Certification must be verified, and the Arborist shall be responsible for all decisions made, and should visit the work sites daily. The Arborist will provide guidance on which roots may be cut and which must be preserved. In general, it is the City’s objective to install the concrete improvements and also preserve the trees. The Arborist’s primary role is NOT just to make a determination on what will happen to the tree if roots are cut, but to help guide the root pruning

City Funded Project Project No. 06911 B.P. Revised 12/21/15 8 September 2019 and concrete repair work with the goal of preserving the tree to the extent possible. The only times when trees will be allowed to be removed is when they are in eminent danger of falling and becoming a danger to the public or diseased to the point of non-recovery. The Arborist’s recommendations may include the application of fertilization, soil amendment, a watering program, etc. However, the implementation of any arborist recommendation beyond root pruning, excavation and grading to bring the proposed concrete improvement to the appropriate level, general protection of the tree during construction and general prudent care during installation of the concrete work shall be considered extra work to be compensated by a contract change order.

The Contractor shall notify the Arborist of the work locations that have been or will be exposed and coordinate an inspection of the tree roots. Roots shall be cut cleanly using a handsaw, loppers or hand shears. Roots shall be cut cleanly prior to use of the backhoe or other excavator to remove material from the site. At no time is the backhoe or other excavator to be used to remove roots.

When tree roots are encountered which are not allowed to be pruned, the Contractor shall excavate only to the extent possible to allow the improvements to be placed flush and conform with the existing improvements, and to remove the tripping hazard as directed by the Arborist.

Under the direction of the Arborist, tree roots shall be cut and removed to a maximum depth of twelve (12) inches below the level of finished grade of the aggregate base. Backfill with six (6) inches clean native backfill material free of organic matter and deleterious material. Wet and compact the aggregate base and the top six (6) inches of native sub-base to 90% maximum relative compaction.

If the Arborist recommends against pruning roots of a particular tree, then the Contractor shall perform one of two tasks as directed by the Arborist and approved by the Engineer. The Contractor shall be directed to (1) construct a concrete curb bend around the tree to keep construction outside of a designated area, or (2) construct the repairs on top of the roots without performing a root cut. Option (2) may require partial grinding of the tree root, and improvements being built directly on top of the tree roots with limited base rock placed on the tree root.

The Contractor shall not perform deep (more than 12 inches) root pruning on both sides of a tree within a 12-month period without authorization from the Engineer due to the risk of causing the tree to fall. The Engineer shall provide historical information on which trees have been pruned in the past.

The following are prohibited in the pursuit of the Contractor’s work when working near trees. DO NOT:  Secure cable, chain or rope to trees or shrubs.  Discharge exhaust into foliage.  Allow fires under and adjacent to trees or other plants.  Cut, break, skin or bruise roots or branches.  Store material, stockpile soil, park or drive vehicles within tree drip lines or in areas with plants.  Allow run off or spillage of damaging materials in the vicinity of the root systems.

that the plastic slopes towards the excavation.

b. Using a sprinkler or soaker hose, apply water slowly to the area of the excavation

for a period of at least 4 hours, approximately 12 hours prior to the work so that

the ground water level is at or near field capacity at the beginning of the work. For

excavations that go beyond the damp soil, rewet the soil as necessary to keep soil

moisture near field capacity.

c. Using an air excavation tool specifically designed and manufactured for the

intended purpose, and at pressures recommended by the manufacturer of the

equipment, fracture the existing soil to the shape and the depths required. Work at

rates and using techniques that do not harm tree roots. Air pressure shall be a

Part 9 - Building Demolition-Lead Based Paint Abatement 1. Description of The Work

A. The work of this Section includes the demolition of buildings and installations where lead based or lead containing paints are present.

City Center Building HAZMAT ABATEMENT 02 82 13 - 27/29 Abatement

B. Submittals:

1) Before Start of Work: Submit the following to the Architect or Owner's Representative for review. Do not start work until these submittals are returned with Owner's Representative's action stamp indicating that the submittal is returned for unrestricted use.

2) Surfactant: Submit product data, use instructions and recommendations from manufacturer of surfactant intended for use. Include data substantiating that material complies with requirements.

C. Abatement of Lead Based Paints

1) Lead was detected in most of the paint samples. The sample results ranged from 110 parts-per-million (ppm) to 1600 ppm in the paint on the HVAC duct work at the roof mechanical room. None of the interior paints were found to contain more than the 0.5% or 5000 ppm threshold or were classified as Lead Based Paints (LBP) for purposes of EPA regulations. Cal OSHA regulations will apply, since the levels of lead in paint were above the detection limit based on the lab reports.

2) Demolition of materials containing lead is a Cal-OSHA level one “trigger task” that assumes exposures will exceed the permissible exposure limit (PEL). For work in public buildings where the PEL is exceeded Cal-OSHA requires that workers be certified by the California Department of Health (DPH). The lead content of most of the paints sampled is high enough that demolition activities disturbing any of them are likely to result in exposures above the PEL. Information concerning the lead sample results must be provided to contractors who in turn must provide employees with lead-specific hazard communication type information including health effects and good hand hygiene practices (e.g., wash hands before eating drinking or smoking, etc.).

3) With regard to the 1600 ppm or other low lead level paint on the steel, stucco, or wood surfaces, demolition activities that disturb it are possible to exceed the PEL only if trigger task activities are used.

4) Furthermore, abrasive blasting, welding, cutting, and torch burning are all Cal- OSHA level 3 “trigger tasks” and employers are required to assume exposures exceed 2,500 ug/M3. The Cal-OSHA lead in construction safety order requires that supplied air respiratory protection be provided for this level of exposure, in addition to lead worker training, certification, hygiene facilities, etc. It is recommended that if any level 3 trigger tasks are to be performed on the steel, then spot-removal of the paint should be conducted first. The paint chips, debris or dust are easily transferred by hand contact so that the importance of good hand hygiene is paramount.

City Center Building HAZMAT ABATEMENT 02 82 13 - 28/29 Abatement

5) The total lead content of many of the paint samples (i.e., the paint of sheet metal and trim) were at the 1,000 ppm total threshold limit concentration (TTLC), and all of the results exceeded 50 ppm, or ten times the 5 ppm soluble threshold limit concentration (STLC) so that loose paint debris must be disposed of as lead hazardous waste. Loose and peeling paints should be removed from surfaces prior to paint stripping or demolition.

6) In order to reduce the amount of lead hazardous waste, it is recommended that the demolition debris should be composited and the samples analyzed by the waste extraction test (WET) for comparison against the 5 ppm STLC. Debris exceeding the STLC must be disposed of as lead hazardous waste.

7) All of the exterior paints above 1000 ppm shall be treated as lead containing paints. Any future removal shall be performed using RRP work methods, following all applicable regulatory guidelines. 8) Any paint removal work shall follow Cal / OSHA regulations regarding trigger task activities, unless the paints are confirmed to be at or below the limit of quantification for lead content. 9) Renovation or demolition work in areas that are not specifically covered by this report shall be re-inspected prior to any disturbance of suspect materials. If the scope of work changes, please allow 24- 48 hours notice for the inspector to perform additional survey work at the site. 10) Notify the consultant 24-48 hours prior to start of any removal or abatement work to arrange for work monitoring and air sampling during the initial phase of the construction, if desired. The construction manager of the project should verify that the abatement contractor is qualified to perform the work and understands the EPA and CDPH specifications and restrictions for working on a public building. A pre job safety meeting is required. Any chemicals to be used on the project must be accompanied by a Safety Data Sheet (“SDS”) and appropriate hazard communication training for all employees at the site.

Asbestos Survey for City Center Building 22300 City Center Drive in Hayward, California

I. INTRODUCTION This report presents our inspection and bulk sampling for asbestos containing materials (“ACM”) at the existing office building at 22300 City Center Drive. in Hayward, CA. The initial inspection was performed from July 30 to September 19, 2019. The facility consists of an eleven story office building. The primary purpose of this inspection is to identify materials, which contain asbestos, which must be removed prior to demolition of the structure. Our scope of work included an asbestos inspection consisting of visual inspection, bulk sampling, laboratory analysis, and the generation of the report findings. The inspection was performed by Mr. Monte Deignan, a Cal/OSHA certified asbestos consultant and AHERA accredited building inspector. Mr. Deignan is also a CA DPH certified lead assessor and inspector.

II. REGULATORY OVERVIEW The following oversight agencies and regulations may affect the implementation of this project as described below: Federal Agencies Environmental Protection Agency (“EPA”), National Emission Standards for Hazardous Air Pollutants (“NESHAP”) Notification 40 CFR 61 Part M • Requires notification when removal or renovation involves greater than 160 square feet or 260 linear feet of friable asbestos containing materials State Agencies / Regulations Bay Area Air Quality Management District (“BAAQMD”) or Cal Air Resources Board • Responsible for enforcement of the federal NESHAP regulations • Requires notification for removal of all friable ACM if exceeding 100 square ft. or 100 linear ft.

Monte Deignan & Associates Certified Asbestos Consultant P.O. Box 546 • Larkspur, CA 94977 • (415) 927-9038 Page 2 of 8 This report may be copied only in its entirety.

• Requires notification prior to demolition regardless of ACM amounts or presence

California Occupational Safety and Health Administration (“Cal/OSHA”) • Responsible for enforcement of Federal OSHA standards • Requires friable and non-friable ACM exceeding 100 square feet to be removed by a registered Cal/OSHA asbestos abatement contractor • Requires that contractors be licensed by the California Contractors State License Board (“CSLB”)

AB 3713 Asbestos Notification Law (Connelley Act) • Requires notification of tenants, employees, and co-owners about the presence and locations of ACM, and the potential health effects

Asbestos Real Estate Disclosure Law • California state law requires the disclosure of ACM presence during real estate transactions.

III. ASBESTOS ANALYSIS PROCEDURES Sampling Strategy The objective of bulk sampling was to determine through laboratory analysis whether suspected materials at this site contain asbestos, and if so, what type and concentrations measured in percentages. Prior to the collection of any samples, all building materials were separated into distinct areas of homogeneity. A homogeneous area represents an area delineated by functional and visual similarity. The area may be further defined by its location within the building, or the age of the material. After homogeneous areas were identified, a sufficient number of samples were collected for submittal to the laboratory for polarized light microscopy (“PLM”) analysis. Because asbestos containing materials have compositional variability, it is possible to obtain different results from samples taken from the same materials in the same building. Therefore, a homogeneous sampling area with at least one positive result will result in the entire area being designated as having asbestos containing material (“ACM”). The collection of bulk samples was based on the guidelines established by the EPA for school buildings (Asbestos Hazard Emergency Response Act (“AHERA”), 40 CFR Part 763, EPA, 1987). In addition, the ASHARA establishes guidelines for the inspection of commercial facilities. AHERA and ASHARA guidelines were used to insure the most reliable procedures for sample collection and reporting.

Monte Deignan & Associates Certified Asbestos Consultant P.O. Box 546 • Larkspur, CA 94977 • (415) 927-9038 Page 3 of 8 This report may be copied only in its entirety.

Standard sampling tools and procedures were used to obtain samples from the suspected materials. The samples were bagged and submitted to the laboratory under standard chain of custody protocols. Representative sample locations were noted on the floor plans of the building and are referenced on the chain of custody form from the laboratory, Microanalytical Laboratories of Emeryville, California. Laboratory Analysis Laboratory analysis was based on polarized light microscopy supplemented by dispersion staining to observe asbestos mineral content. For the purposes of this survey, ACM is defined as any material containing more than 1% asbestos by weight, volume, or point count. For Cal/OSHA purposes, Asbestos Containing Construction Materials (ACCM) is defined as any material with greater than 0.1% asbestos.

IV. VISUAL SURVEY FINDINGS On the mornings of July 30th and 31st, 2019 the first inspection of the facility was performed, after a brief meeting with public works contact. Samples were also collected from the remaining suspect materials found at the site. The inspection process was described and a brief walk-through was performed. The age of the building and the use of asbestos containing materials are usually related. Additional inspections were performed on Sept. 03 and Sept. 19, 2019. Most buildings from the late 1960’s used asbestos in numerous applications. Previous Abatement at the Site It appears from visual inspection that a substantial amount of the interior finishes and TSI on piping have been removed during previous asbestos abatement work. Most of the office partition walls have been removed during the previous abatement work. It appears that the floor has been bead blasted as part of the abatement operations. Most of the duct work and HVAC distribution system above the ceilings have been removed as part of the abatement work. The core areas at each floor have been left at the elevators, rest rooms, mechanical room, and stairwells. The basement and mechanical penthouse do not appear to have been as extensively abated. Walls and Structural Components The office building consists of concrete framed exterior walls with metal-framed interior walls, using a concrete foundation. Each of the floors uses a concrete slab system. The exterior walls are sheathed with window units secured with rubber neoprene gaskets. The window gaskets are sealed with caulking or sealant at the exterior face. The roof is concrete slab roof structure for the main roof and equipment room. Roofing Components The flat roof uses a built up tar and felt system finished with a rock ballast layer. The coved up sections along the perimeter use #90 mineral surface roll roofing. Roof cements are found at most of the roof jacks, vent exhausts, and patched locations. The as-built plans for the building indicates that the below grade water proofing uses asbestos containing materials, such as

Monte Deignan & Associates Certified Asbestos Consultant P.O. Box 546 • Larkspur, CA 94977 • (415) 927-9038 Page 4 of 8 This report may be copied only in its entirety.

protection board for the membrane. It should be assumed that any water proofing membrane will be asbestos containing as well. Interior Finish Components The remaining interior walls are drywall with joint compounds or plaster at core mechanical and rest room areas. The interior ceilings of the remaining rooms are drywall for lower ceilings with remnants of Celotex acoustic ceiling panels found along the perimeter walls. The flooring has been removed except for rest rooms areas, for the most part. The rest rooms use a combination of ceramic tile and vinyl sheet flooring. Minor areas of residual floor filler and mastics are noted at the different floors. The elevator lobbies use a Travertine stone facing over thin-set adhesive. The lobby level uses paver or ceramic tile for the common areas.

The former City Council chambers were inspected on the second site visit. The council chambers use a perimeter skylight system that is assumed to have asbestos in the glazing compound / putty. The inspection did not cover below grade water proofing on the foundation walls, subsurface drain lines, etc. for example. Based on review of as built plans, the below grade water proofing is specified to use asbestos. If materials are noted that appear different from the other materials listed in the sample descriptions, arrange for follow up inspections. Mechanical Systems, Utilities, etc. The mechanical and HVAC systems consist of boiler and air conditioning chillers located at the roof level mechanical room. Most of the equipment has been dismantled in a crude fashion by scavengers after the building was vacated. Gaskets used at pipe flanges have been damaged / disturbed and contain asbestos. Most of the copper wiring and piping have been removed. The heat exchangers on the different floor levels have also been opened up to access the copper pipes. The hot / chilled water pipe system uses mostly fiberglass, with some hard cast thermal system insulation (TSI) found on valves, controls, or fittings. A tan colored duct tape if found on the remaining HVAC ducts. As part of the chiller system, a cooling tower is located on the roof at the East side. A honeycomb matrix is used as part of the water cooling system in the tower. The honeycomb material has been damaged and the debris is spread around the tower assembly. The hot water boiler found in the roof area equipment room appears to have the thermal system insulation removed during previous abatement work in the building. The interior of the boiler does not appear to have additional suspect insulations. The elevators for the building consist of four elevator shafts, with a cable system to lift the cars. The elevator motor units are located in the equipment room and use brake shoes to stop the elevator cars. The brake shoes are suspect for asbestos content. The doors for the elevators at each level are fire rated and have an interior insulation material. All of the fire rated doors at stairwells and machine rooms are assumed positive for an interior ACM insulation layer. A small incinerator was noted at the roof area and the interior of the unit uses a refractory or fire brick. No other suspect insulation was noted on the incinerator at the West side of the equipment room.

Monte Deignan & Associates Certified Asbestos Consultant P.O. Box 546 • Larkspur, CA 94977 • (415) 927-9038 Page 5 of 8 This report may be copied only in its entirety.

The lighting in the building used fixtures containing fluorescent lamps. The ballasts for the lamps are suspect for PCB content. A quick review of the remaining ballasts confirms that the ballasts contain PCB and must be remediated prior to demolition. The fluorescent tubes must be recycled at the time of removal or before demolition.

Sampling of Building Materials Samples were collected from eighty-nine different building materials during the this survey. Since no other suspect asbestos materials could be found, the sampling was considered complete. All of the samples were catalogued as to location, condition, and submitted for PLM analysis. The samples were hand-delivered to the laboratory using our standard chain of custody protocols after the inspections from July 31, 2019 to September 19, 2019. An additional 5 lead samples were collected on the same date as the asbestos samples. The chipping and peeling paints at the equipment were low in lead content. The ceramic tiles were non detect for lead content. Minor abatement of chipping and peeling paints should be performed at the time of asbestos abatement in the machine or equipment room areas. The exterior paints on the structure are mostly in fair to good condition, with chipping and peeling noted only at interior machine rooms. No paint samples were collected for the purpose of waste characterization at this time, but should be performed at the time of demolition. Many of the insulation products in this building are fiberglass, which may require special handling methods to maintain exposure levels below OSHA permissible exposure limits (PEL). Construction workers are advised to minimize damaging and disturbing fiberglass insulation. All construction personnel are advised to refer to the OSHA guidelines for safe working procedures and personnel monitoring requirements when disturbing fiberglass insulation materials. The current pre-demolition requirement for a PCB assessment applies to this site. A separate report addresses the PCB testing and abatement requirements for the priority building materials. Due to the extended period of time that the building has been vacant, there is a substantial amount of debris from the temporary tenants. Some of the debris contains biological hazards from human waste, drug paraphernalia, etc. During the inspection, droppings from birds and rodents were noted in multiple areas. The openings in the elevator shafts will require temporary rails and the use of appropriate fall protection for any work in the vicinity. A number of the window units are broken and missing. Fall protection will be needed for any work near un-protected openings. Roof abatement above the equipment room will require fall protection for workers within six feet from the edge.

V. CONCLUSIONS Based on the visual inspection, sampling and laboratory analysis, the following results are noted: • The fire rated doors at stairs, elevators, and mechanical rooms are asbestos containing. • The honeycomb panels at the cooling tower are asbestos containing. • The vinyl sheet floorings at the rest rooms are positive for asbestos in the mastics. • The glazing compounds at the council chambers skylights are assumed ACM positive. • The roof felts, membranes, and roof cements at all roof areas are positive for asbestos. • The interior gypsum board / drywall walls are asbestos containing in the compounds. • The brake shoes for the elevator system contain asbestos. • The gaskets used on chilled / heated water pumps, valves, pipes, and flanges contain asbestos. Some disassembly will be required for existing equipment. • The hard cast thermal system insulation on hot or chilled water lines contain asbestos. • The water proofing / Transite panels below grade are assumed to contain asbestos. • The exterior caulking at the window gaskets contain asbestos at all locations. • The acoustic ceiling panels are negative for asbestos. • The interior plaster contains asbestos at the former City Council Chambers. • The stucco at exterior and soffit areas are non-detect for asbestos. • The concrete elements, tile, and thin set mastic materials were all non-detect for asbestos. • The refractory brick at the incinerator was non-detect for asbestos. • The tan colored duct tapes on HVAC ducts are non-detect for asbestos. • The remaining lights in the building are mostly fitted with fluorescent tubes or bulbs and will require recycling prior to demolition. The ballasts in the lighting fixtures shall be checked for possible PCB content, prior to demolition. A separate report for PCBs in other materials will cover PCB in priority building materials.

VI. RECOMMENDATIONS Based on the visual inspection, sampling and laboratory analysis conducted, the following recommendations apply to the materials found on this site: 1. The elevator doors and other fire doors must be abated prior to demolition of the building. It is recommended to unbolt the doors from their frames and remove intact, following all applicable regulatory guidelines.

Monte Deignan & Associates Certified Asbestos Consultant P.O. Box 546 • Larkspur, CA 94977 • (415) 927-9038 Page 7 of 8 This report may be copied only in its entirety.

2. The honeycomb matrix at the cooling tower must be abated prior to any demolition. There is substantial debris that must be collected as well. 3. The roof felts, membranes, and roof cements at all areas must be abated prior to demolition. Water proofing membranes and Transite below grade must be abated prior to demolition. 4. The window caulking must be abated prior to demolition at all window and filler panels. 5. The skylight glazing compounds at the City Council Chamber must be abated prior to demolition work. Confirmation testing is recommended when access is available. 6. The vinyl sheet flooring and floor mastics must be abated prior to demolition of the building. Any removal shall be performed using negative pressure containment, Wet methods, following all applicable regulatory guidelines. 7. The drywall compound and joint tape materials at the wall and ceiling areas contain more than 1 % asbestos. Asbestos PLM point count testing is recommended to potentially allow treating as less than 1% asbestos. The removal of the gypsum board / drywall will require the use of abatement contractors using wet methods, critical barriers, following all regulatory requirements. Notification to the AQMD and waste handling will be required for ACM. Cal / OSHA does not accept composite type of analysis, thus drywall removal will require contractors registered for asbestos related work. All drywall debris must be disposed of in leak tight containers with appropriate warning labels. Cal / OSHA regulations apply to materials with any detectable asbestos, such as this. 8. The remaining thermal system insulation on pipes/ fittings is friable asbestos. Any removal will require Cal / OSHA friable Class I work practices, with negative pressure containment, wet methods, worker training, and proper disposal. 9. The elevator brake shoes must be removed prior to demolition. Mechanical disassembly is the recommended method for removal to keep the materials as non-friable. 10. The acoustic panels, concrete, stucco / plaster / masonry, duct tapes, and tile materials in the buildings do not require any asbestos abatement work / removal. 11. Notification to the BAAQMD is required for the regulated asbestos containing materials found in the building. An additional notification is required for the demolition of the building. 12. All of the fluorescent tubes shall be collected for recycling. All ballasts shall be remediated due to PCB content. 13. Notify the asbestos consultant to arrange for additional sampling if different types of flooring or roofing products are discovered during the course of the demolition. Any chemicals to be used on the project must be accompanied by a Safety Data Sheet (“SDS”) and appropriate hazard communication training for all employees at the site.

VII. LIMITATIONS OF LIABILITY The work and resulting recommendations for this survey are in accordance with generally accepted building survey practices and the AHERA protocols for asbestos inspections. The report generators provide no other guarantees, either expressed or implied. Conclusions and recommendations presented in issued reports are qualitative judgments based on the prevailing regulations affecting the scope of this work at the time of the inspection of the particular building(s). The scope of work was limited to the visible and accessible parts of the building, limited sampling analysis, and data review. The client recognizes that site conditions or access may vary from those encountered at the time of the inspection, and that changing conditions may cause us to alter our recommendations. We have attempted to view as much of the building as possible, without opening hidden areas, removing all of the ceiling panels, or damaging existing property. If conditions or situations occur that expose these non-inspected areas, we will be glad to continue our inspection at that time for those locations. This report is for the express use of the client for whom it was prepared, and is not intended for use by third parties. The authors of this report will not be responsible for interpretation or sue by third parties of any of the information contained in this report. The building survey for asbestos is intended to provide an initial assessment of asbestos containing material at specific locations, and may not be valid at other locations or for other unique materials. Additional site evaluations could result in information that would lead us to revise our conclusions and recommendations. If any doubts exist, call for additional inspections or testing.

PCB Survey for City Center Tower Building 22300 City Center Drive in Hayward, California

I. INTRODUCTION This report presents our inspection and bulk sampling for polychlorinated biphenyls (“PCB”) at the existing City Center Building at 22300 City Center Drive in Hayward, CA. The initial inspection was performed on July 30-31, 2019. Additional inspections were performed in September 2019. The facility consists of an eleven story office building, which has been vacant for a number of years. The primary purpose of this inspection is to identify materials, which contain PCB, which must be removed prior to demolition of the structure. Our scope of work included an PCB inspection consisting of visual inspection, bulk sampling, laboratory analysis, and the generation of the report findings. The inspection was performed by Mr. Monte Deignan, a Cal/OSHA certified asbestos consultant and AHERA accredited building inspector. Mr. Deignan is also a CA DPH certified lead assessor and inspector. There are currently no certification requirements for PCB inspectors.

II. REGULATORY OVERVIEW The following oversight agencies and regulations may affect the implementation of this project as described below: Federal Agencies Building materials containing PCBs at or above 50 ppm that were manufactured using PCBs fall under the category of PCB material / waste. Such materials typically include: joint sealants, caulk, window / door gaskets, mastics, insulation, etc. Refer to Code of Federal Regulations (CFR) 761.3 for a more detailed definition of PCB bulk product wastes. • Disposal of PCB wastes are subject to Toxic Substances Control Act (TSCA) requirement, such as manifesting of the waste for transportation and disposal. Refer to 40 CFR 761 and 40 CFR 761, subpart K.

Monte Deignan & Associates Environmental Consulting P.O. Box 546 • Larkspur, CA 94977 • (415) 927-9038 Page 2 of 7 This report may be copied only in its entirety.

• Building materials such as concrete, brick, and metal contaminated with PCB are considered PCB remediation wastes. Refer to 40 CFR 761.3 for definition of PCB remediation wastes. • TSCA regulated does not apply solely to materials containing PCBs at or above 50 ppm. There are circumstances where materials containing PCBs below 50 PPM are subject to TSCA regulations. Refer to 40 CFR 761.61(a)(5)(i)(B)(2)(ii) for specifics. State Agencies / Regulations • The disposal of PCB waste is subject to California Code of Regulations (CCR) Title 22, Sections Division 4.5, Chapter 12, Standards Applicable to Hazardous Waste Generators. • PCB wastes are regulated as hazardous waste by Department of Toxic Substances Control (DTSC) under the Health and Safety Code (HSC). • Criteria for determining PCB wastes are the following: total threshold limit concentration (TTLC) of 50 ppm and above of PCB, soluble threshold limit concentration (STLC) of 5 ppm and above as an oily liquid.

San Francisco Bay Area Regional Water Quality Control Board (RWQC) • The regional water board in 2015 reissued the Municipal Regional Permit (MRP) that regulates discharges of storm water runoff. The MRP includes provisions for reducing discharges of PCB in storm water runoff and requires municipalities to develop a program to manage PCB priority building materials prior to demolition and implement the program prior to July 01, 2019. • Applicable structures are defined as buildings constructed or renovated between January 01, 1950 and December 31, 1980. Wood frame buildings and single family residences are exempt from the applicable structures definition, regardless of age. • Priority Building Materials are listed as: caulk, rubber window gaskets, adhesive mastics, thermal system insulations, and fiberglass insulation. • Lighting ballasts, transformer fluids, polyurethane foams, etc. which may all contain PCBs, are traditionally managed prior to demolition under current state and federal regulations that require removal / disposal of as universal wastes. The Bay Area Stormwater Management Agencies Association (BASMAA) assumes that the ballasts, transformer fluids, polyurethane foams will be treated under the existing separate programs.

Safety and Health Procedures • All equipment and wastes containing or contaminated with PCB shall be properly labeled to alert workers to the special handling and disposal requirements. • Any time that contact with PCB waste or materials is possible, the use of personal protective equipment (PPE) must be used. PPE typically consists of gloves, eye wear, disposable coveralls, and respiratory protection for liquid and airborne mist situations. Contaminated clothing and gear must be disposed of as PCB waste.

Monte Deignan & Associates Environmental Consulting P.O. Box 546 • Larkspur, CA 94977 • (415) 927-9038 Page 3 of 7 This report may be copied only in its entirety.

• Monitoring to confirm that employees are not exposed above the PEL without correct PPE.

III. PCB ANALYSIS PROCEDURES Sampling Strategy PCBs are mixtures of synthetic organic chemicals with the same chemical structure and physical properties ranging from an oily liquid to a wax like solid. PCB were used in hundreds of industrial and commercial applications due to their insulating properties, high boiling point, non-flammability, and chemical stability. Production of PCBs was ceased in 1977, with some building products still containing PCBs up to approximately 1980. PCBs are known to cause a variety of adverse health effects including cancers, immune system disorders, reproductive system disorders, nervous system disorders, etc. Since PCBs do not break down easily in the environment, debris from building demolition is susceptible to being transported by storm water discharges into the San Francisco Bay, where it may remain or be introduced into the aquatic food chain. Starting on July 1, 2019, demolition of applicable structures must be tested for PCB content in a list of priority building materials. Materials with PCB at or above 50 ppm must be remediated prior to demolition of the building. Local building departments are required to obtain a BASMAA format screening assessment form prior to issuance of a demolition permit. Standard sampling tools and procedures were used to obtain samples from the suspect priority building materials. The samples were collected in glass jars, with Teflon lids and submitted to the laboratory under standard chain of custody protocols. Representative sample locations were noted on the floor plans of the building and are referenced on the chain of custody form from the laboratory, Enthalpy Laboratories of Berkeley, California. Laboratory Analysis Laboratory analysis was based on EPA 8082 PCB analysis, with an initial EPA 3540 SOXHLET extraction process. For the purposes of this survey, regulated PCB is defined as any material containing 50 ppm or above. For oily liquid materials, a STLC level of 5 ppm or above is classified as a PCB regulated waste.

IV. VISUAL SURVEY FINDINGS On July 30-31st and September 03rd, 2019 the inspection of the facility was performed, after a brief meeting with the public works department contact. Samples were also collected from the various interior and exterior components. The age of the building and the use of PCM containing materials are usually related. Most buildings from the early 1950’s up to 1980 used PCBs in numerous applications. The as built drawings for the office tower show a construction date of 1969, thus the building falls well within the applicable dates for PCB containing components. An asbestos survey was conducted at the same time and found a number of components that will require remediation or abatement for asbestos prior to demolition.

Office Tower Building: Walls and Structural Components The office building consists of concrete framed exterior walls with limited masonry planters in the entrance area, using a concrete foundation. The roof is concrete slab roof structure for the main roof. Most of the flooring finishes have been removed during previous abatement work at the site. Caulking is found at the window exterior gaskets. All of the windows use a neoprene gasket to secure the glazing in the frames. The insulation at walls and above ceilings have been removed or were minimal.

Priority Building Materials Priority Building Materials are listed as: caulk, rubber window gaskets, adhesive mastics, thermal system insulations, and fiberglass insulation. Caulk is found at the exterior face of the window gaskets and at the expansion joint on the grade level walkways around the building. Rubber window gaskets are found at all of the main windows frames. There are different types of gasket depending on the frame material of concrete or metal. Adhesive mastics are found in remaining floor mastics that were not abated previously. Thermal system insulation at the site consist of residual fiberglass insulation on hot water piping. Some of the hard cast cementitious TSI that remains contain asbestos and were not tested for PCB content, since they will be abated prior to demolition.

Some materials or components were not accessed during the course of this inspection. The inspection did not cover behind metal trim, or other priority building materials covered by newer finish surfaces, etc. for example. If materials are noted that appear different from the other materials listed in the sample descriptions, arrange for follow up inspections.

Sampling of Building Materials Samples were collected from the twenty-five different building materials during this survey. Since no other suspect materials could be found, the sampling was considered complete. All of the samples were catalogued as to location, condition, and submitted for EPA 8082 PCB analysis. The samples were hand-delivered to the Enthalpy Analytical laboratory using our standard chain of custody protocols on the afternoon of July 30-31, 2019 and September 03, 2019.

Quality Assurance and Quality Control Part of the submittal requirements call for the use of a QA/QC checklist. • Proper sampling equipment was used: tools consisting of utility knives and chisels were cleaned before use. Sample containers were glass jars, with Teflon lids. • Proper decontamination procedures used: The tools were cleaned after each use following the three bucket method to prevent cross contamination of samples. • Sampling collection spatial frequency was achieved: For each type of priority building material, the appropriate 3-5-7 rules for the correct number of bulk samples was followed. • Samples were received by the lab within the proper temperature and time range: The samples were delivered in a cooler on the same afternoon that the samples were collected. • A National Environmental Laboratory Accreditation Program (NELAP) was used: Enthalpy Analytical Lab in Berkeley, CA was the lab used for the analysis. • Samples were extracted and analyzed within the method holding time for EPA 8082 PCB analysis: The lab report indicates compliance with the EPA 3542 SOXHLET extraction process. • Sample reporting limit met data quality objectives: The reporting limit for each sample was below the 50 ppm regulatory threshold.

V. CONCLUSIONS Based on the visual inspection, sampling and laboratory analysis, the following results are noted: • The rubber window gaskets and caulking all contain PCB, above the 50 ppm level. • The expansion joints contain PCB above the 50 ppm level. The tile and mortar adjacent to the expansion joints shall be treated as PCB contaminated and abated within 2 inches of the joints. • The fiberglass insulation in the office building were non detect for PCB. • The floor mastics at the office building basement only contain PCB, above the 50 ppm level. • The lights in the building are mostly fitted with fluorescent tubes or bulbs and will require recycling if the light fixtures are removed or replaced. The ballasts in the lighting fixtures shall be checked for possible PCB content, which may be covered under the previous environmental surveys. Any ballast without a “No PCB” label is to be abated / remediated. Any transformers in utility rooms or vaults shall be assumed to contained PCB above 50 ppm.

VI. RECOMMENDATIONS Based on the visual inspection, sampling and laboratory analysis conducted, the following recommendations apply to the materials found on this site: 1. The window gaskets, caulking, and expansion joints shall be remediated as PCB materials using work practices that prevent release the materials into the environment. Workers shall use full PPE for PCB type of remediation. The removal methods shall prevent the materials from becoming airborne and shall prevent waste from leaving the work area. The waste shall be packaged in leak tight and labeled containers. The waste shall be delivered to an approved waste or disposal facility for PCB, using hazardous waste manifests. 2. The other priority materials were found to contain less than 50 ppm. No remediation is required if the results are less than 50 ppm or the materials are abated due to asbestos content. Lighting ballasts are to be reviewed and handled per existing regulations based on earlier reports. 3. Notification to the local building department is required for the BASMAA assessment screening application form. A copy of this report and lab results are part of the required submittal. 4. Notify the environmental consultant to arrange for additional sampling if different types of priority building products are discovered during the course of the demolition. Any chemicals to be used on the project must be accompanied by a Safety Data Sheet (“SDS”) and appropriate hazard communication training for all employees at the site.

VII. LIMITATIONS OF LIABILITY The work and resulting recommendations for this survey are in accordance with generally accepted building survey practices and the BASMAA protocols for PCB inspections. The report generators provide no other guarantees, either expressed or implied. Conclusions and recommendations presented in issued reports are qualitative judgments based on the prevailing regulations affecting the scope of this work at the time of the inspection of the particular building(s). The scope of work was limited to the visible and accessible parts of the building, limited sampling analysis, and data review. The client recognizes that site conditions or access may vary from those encountered at the time of the inspection, and that changing conditions may cause us to alter our recommendations. We have attempted to view as much of the building as possible, without opening hidden areas, removing all of the ceiling panels, or damaging existing property. If conditions or situations occur that expose these non-inspected areas, we will be glad to continue our inspection at that time for those locations. This report is for the express use of the client for whom it was prepared, and is not intended for use by third parties. The authors of this report will not be responsible for interpretation or sue by third parties of any of the information contained in this report. The building survey for PCB is intended to provide an initial assessment of PCB materials at specific locations, and may not be valid at other locations or for other unique materials. Additional site evaluations could result in information that would lead us to revise our conclusions and recommendations. If any doubts exist, call for additional inspections or testing. Respectfully submitted,

Monte Deignan Principal

The window units from the third to eleventh floor use a heavy neoprene rubber gasket to secure the glass and filler panels. The gasket is sealed at MDA the exterior face using a black colored caulking. The gasket is inserted into a reglet or notch in the concrete jamb, sill, or head areas. An aluminum fitting is mounted in the jambs to hold the gasket. The metal channel also prevents the PCB oils from directly leeching into the porous wall surfaces. Supplemental testing is pending that will confirm the concrete jamb does not contain more than 50 ppm of PCB contamination. Monte Deignan Photo 3 shows the gasket cut and partially removed for PCB testing. The sample ID is marked on the adjacent concrete jamb. & Associates Photo 4 is a detail from the as built construction drawings showing a section view through the jamb.

This data package contains sample and QC results for three black caulking samples, two blk/wht caulking samples, and one tan/brown fiber glas sample, requested for the above referenced project on 07/30/19. The samples were received cold and intact.

PCBs (EPA 8082): All samples underwent sulfuric acid cleanup using EPA Method 3665A. All samples underwent sulfur cleanup using the copper option in EPA Method 3660B. PCC-13:GASKET (lab # 312320-003) was diluted due to foaming. PCC-14:EXP. JOINT (lab # 312320-004) and PCC-15:EXP. JOINT (lab # 312320-005) were diluted due to client history of high non-target or organic acid interference. PCC-11:GASKET (lab # 312320-001) and PCC-16:EXP. JOINT (lab # 312320-006) were diluted due to the color of the sample extracts. No other analytical problems were encountered.

This data package contains sample and QC results for nine gasket samples, requested for the above referenced project on 09/03/19. The samples were received intact.

PCBs (EPA 8082): All samples underwent sulfuric acid cleanup using EPA Method 3665A. All samples underwent sulfur cleanup using the copper option in EPA Method 3660B. Low surrogate recovery was observed for decachlorobiphenyl in PCC-108:GASKET (lab # 313556-008); results may be biased slightly low. A number of samples were diluted due to foaming. No other analytical problems were encountered.

MEMORANDUM

TO: Ms. Terri McCracken PlaceWorks 1625 Shattuck Avenue, Suite 300 Berkeley, CA 94709

FROM: Jim Martin ENVIRONMENTAL COLLABORATIVE

DATE: 13 August 2019

SUBJECT: Results of Bat and Bird Nesting Survey Former City Hall Building Demolition Project Hayward, California

The memo summarizes the results of the survey for nesting birds and roosting bats conducted for the former City Hall Building in Hayward, located on City Center Drive. The City is planning to demolish the building, which has been vacant since it was damaged during the Loma Prieta Earthquake in 1989. The structure is 10 stories in height, with the bottom floor partially below grade. It has been occupied by squatters at various points over the past 30 years, but has been cleared of occupants and remains vacant.

The City requested that Environmental Collaborative assess the potential for nesting birds and roosting bats to better understand whether they could pose a constraint, or affect the schedule for demolition. Nests of native birds in active use are protected under the federal Migratory Bird Treaty Act and State Fish and Game Code. Some species of bats are recognized as Species of Special Concern by the California Department of Fish and Wildlife (CDFW), maternity bat roosts in particular being considered important wildlife habitat as nursery sites.

Methods

I, Jim Martin of Environmental Collaborative, conducted the survey on Friday, July 19, 2019, and was accompanied by Suzanne Philis from the City’s Economic Development Department. After entering the building, I inspected accessible areas on each floor, using a hand-held high powered flashlight when light levels were low. The building has undergone interior demolition in the past on most of the floors, with most of the floor coverings, partitions, fixtures, wiring and false ceilings removed. Most of the remaining windows have been painted over, and many of the broken and missing windows have been replaced with sheets of plywood or open metal grates that have been bolted into place.

Upon entering each floor from either the east or west stairwells, I inspected the perimeter of the

1 floor from the outside and interior walls, as well as the remaining central rooms where bathrooms and utility closets were once located. I inspected the floors and ceilings for any signs of birds or bats, including dead animals, droppings, white wash, feathers, nest materials, egg shells or other signs of possible presence. Where observations were made, the location was noted and summarized in a field survey form. Locations where access into the building is still possible by birds and bats was also noted, including broken or missing windows, doors, and ventilation screening. An inventory of missing or broken windows is contained in Attachment A, together with representative photographs showing current conditions.

Results

The only sign of wildlife activity observed during the inspection was of non-native rats and pigeons (Columba livia). Rat droppings were observed on many of the floors in varying amounts, although no dead rats were encountered. Pigeons are entering the building through missing windows on Floors 3, 4, 6, 7, 8, and 9, as well as the top flights of the stairwells, and utility rooms on the roof. Occupation by pigeons on each floor varies, based on the amount of bird droppings. Eggs were found near the east stairwell entrance to the 9th floor, and two young pigeons were still in their nest on the west stairwell to the rooftop. Piles of pigeon feathers were observed in the largest of the rooms on the roof where ventilation screening was missing and doors are left open, likely resulting from pigeons being preyed on by a falcon or other raptor.

The only nesting observed inside the building was by non-native pigeons. Nests and eggshells were observed in the east stairwell leading to the 9th Floor, and a nest occupied by two juvenile birds was observed in the west stairwell between the 9th Floor and access to the roof level. Concentrations of pigeon droppings were observed on several floors on the north side of the central rooms, where utility ducts and other surfaces above the bathrooms and utility rooms provide perching and possible nesting substrate. No other evidence of any active bird nesting was observed in or on the building.

Missing windows allow for access by pigeons and other birds on most floors of the building. An estimate of missing window coverings (plywood or metal grates) was made on each floor, which are tabulated and summarized in Appendix A. Photographs showing the interior condition, window coverings, and missing window/door/vent coverings that allow for access by birds and other wildlife are also shown in Appendix A. A total of 52 window coverings were missing on floors 2 through 9 of the building, and most openings (doors, windows, vents) to the stairwell and utility rooms on the roof are also missing coverings which allows unobstructed access by birds. Pigeons and their signs of occupation were observed on seven levels of the building (including the utility rooms on the roof level).

No signs of any bat presence were observed anywhere in the building. This included absence of any bat guano, dead bats, or characteristic landing and perching areas. Given that most of the interior is now gutted and open, roost habitat is largely absent in the structure. Future occupation of the structure before demolition seems unlikely given the marginal habitat quality and fact that bats haven’t been utilizing the structure with the numerous missing windows and other access points.

Conclusions and Recommendations

Although no evidence of native birds or bats were observed during the building assessment, there remains a potential for future bird or bat occupation prior to the start of demolition activities. As indicated above, nests of native birds in active use are protected from destruction under State and federal law. Birds typically nest from early March through the end of August, 2 and once a nest is occupied it would have to be avoided until any young have fledged, which could significantly delay building demolition. Similarly, maternity roosts of native bats are considered a sensitive resource by CDFW, some species are further recognized as SSC and should be addressed as part of any CEQA review.

The constraints that nests in active use pose to building demolition can be avoided by timing the demolition outside the bird nesting season. In the Hayward area, native birds typically nest from March 1 through August 31. If demolition can be completed before March 1, 2020, no further treatment or controls on wildlife access into the building would be necessary. No evidence of any native bird nesting or bat roosting was observed, and retrofitting all of the missing windows, doors, and vents would be a large undertaking for a building slated for demolition.

If demolition can’t be scheduled outside the bird nesting season, it would be advisable for the City to consider sealing off the missing windows, doors and vents prior to the onset of the nesting season. This would help preclude the potential for native birds to gain access to the building and establish new nests that would have to be avoided until any young have fledged. There is really no way to fully seal up the structure from possible bat occupation without effectively sealing each of the plywood and grated openings, but this seems unwarranted given the interior condition of the building and very remote potential for establishing roosting habitat.

My suggestion is that the City re-evaluate the status of building demolition in January 2020, and if demolition can’t be accomplished before March 1, 2020, that the unsealed windows, doors and vents in the building be sealed before that time. This should prevent birds from gaining access inside the building, establishing new nests, and affecting timing of building demolition. Alternatively, the City could schedule building demolition after the end of the bird nesting season later in 2020, after August 31st.

I trust this provides you with the information requested regarding bird and bat occupation of the former City Center Building. Please feel free to contact me at 510-393-0770 if you have any questions regarding the above assessment.

(WC3) has performed a structural assessment of the property located at 22300 Foothill Boulevard, Hayward, California. The objectives and scope of this assessment were planned in discussions between Catherine Ralston and Gary Nordahl of Hayward City and Giyan Senaratne and Mike Molyneux of WC3. In general, the objectives of this assessment were to: 1. Assess the overall structural condition of the building. 2. Identify portions of the building that are, or may be, structurally deficient. 3. Review the recommendations from past structural evaluations. 4. Recommend repairs for deficiencies found in the structure. 5. Provide preliminary cost estimates for needed repairs. 6. Hazardous materials. 7. Provide potential recommendations for demolition. 1.2 Background The property consists of an eleven-story reinforced concrete non-ductile moment-frame structure. The structure was completed in 1969 and served as city hall for Hayward City as well as leasing out other floors of the building to businesses. It is our understanding that after the Loma Prieta earthquake in 1989, City Hall was relocated to another facility and the City Hall office building was sold. A structural assessment of the existing structure was completed in 1990, 1991, and 1992 where renovations were recommended. These renovations were never completed, and the structure has not been in use since 1990. During this time the old City Hall office building have been used by vagrants. There are several locations where it appears that destructive testing has been done to verify reinforcement conditions. Infill framing and finishes have been removed. The elevator core and stairway shafts are framed with steel studs and are exposed in many locations. The gypboard at the stair shafts has been damaged in many locations. Hayward City would like to know if the structure can be retrofitted or if demolition would be recommended.

1.3 Building Description The high-rise office building is an eleven-story, concrete slab, beam, girder, and column structure. The lateral force resisting system consists of concrete non-ductile moment frames. The concrete columns around the exterior of the structure along with spandrel beams comprise the concrete moment frames at the upper levels. The bottom two levels consist of a plaza which transitions to larger concrete moment frames with larger beams and columns. Concrete beams run east/west with concrete girders spanning north and south between concrete columns. A 3-1/2 inch concrete slab spans the estimated 2’-6” space between the beams. Steel stairs join each level at the north and south ends of the structure. Elevator and stair shafts are found in the middle of the building as well. People can enter the building from the second

The top floor or roof contains a mechanical penthouse surrounded by an asphaltic gravel covering and a tall parapet wall around the entire exterior.

1.4 Applicable Codes Currently, the State of California has adopted both the 2016 California Building Code (based on the 2015 IBC) and the Uniform Code for the Abatement of Dangerous Buildings (UCADB) for use in ensuring that both new and existing buildings meet a minimum level of life safety. Both of these codes were used in performing this assessment of the project and are referenced throughout this report. The 2019 version of the California Building Code will be effective January 1, 2020.

2.1 Site Inspection Summary A site inspection was conducted by Mike Molyneux of WC3, Gary Nordhal and Sammy Lo of Hayward City, and Tim Cannard of Kellco Services on Tuesday, July 9th, 2019. During the site visit a visual inspection of the structural conditions, code-related issues, and potential hazardous materials was performed. Table 1 shows some structural items of interest that were discovered during the site inspection.

Table 1. Photos and Descriptions

Photo #1: This is a photo from the east side of the building. The concrete frame of the upper nine stories can be seen. The openings are two feet, six inches wide with two-foot, six-inch columns in between. One of the larger columns for the plaza level can be seen at the bottom of the picture.

Photo #2: This photo shows the typical floor construction. Similar floor construction was seen at all levels. Concrete girders span the 25’-0” between the concrete columns at each floor with concrete beams/purlins spaced at roughly 2’-6” on center. No significant cracking was seen in the beams, girders, columns, or slab throughout the building.

Photo #3: This photo shows the non-ductile concrete frame from the interior. No significant cracking could be seen at the top or bottom of the concrete columns. The change in color at the base that can be seen in the picture is from removal of the floor finishes. This is not spalling or cracking of the concrete columns.

Photo #4:

This photo shows the extent of the concrete frames along a typical north and south side of the building. No significant cracking can be seen in the concrete floor slab. The metal cage/grating that has been added at the openings throughout can be seen in the picture as well.

Photo #5: This photo shows a retrofit brace that was added at some point. There are no design calculations or clarification as to why this was added in any of the reports reviewed as part of this investigation. The adjacent column has exposed rebar and a cut section which appears to have been done as part of destructive testing. It is assumed that this brace was added to provide lateral support at this level where destructive testing has been done. See the following picture.

Photo #6: This photo shows a section of a typical concrete column where the outer concrete has been removed to expose the steel reinforcement. The reinforcement shown does not meet the requirements of Sections 18.7.5.2 and 18.7.5.3 of ACI 318-14 for transverse reinforcement for moment frame columns. These sections of the ACI provide for more ductile frames and decrease the risk for catastrophic failure. As a result, it is clear that the existing structure is a non-ductile concrete building.

Photo #7: This photo shows the longitudinal reinforcement of the moment frame columns as well as the ties and tie spacing. The tie spacing is reported as twelve inches on center in the February1990 report provided by EQE Engineering. The reinforcement could only be verified at this location but is assumed to be typical throughout. A change of reinforcement at higher levels would be normal as the cumulative seismic loads at higher levels would be lower.

Photo #8:

This photo shows a typical concrete column cross section that has been cut. It is assumed that the cut was made to verify the typical longitudinal reinforcement. This column was cut in the east side of the building at one of the lower levels. The concrete floor beams span parallel to this wall. This wall would have less gravity load but is still considered part of the lateral force resisting system. It is assumed therefore the brace in previous pictures was added.

Photo #9:

This photo shows the condition of much of the infill framing around the stairwells. The steel studs are still there but many of them are bent and the gypboard is missing. These walls are non-load bearing.

Photo #10:

This photo shows a typical masonry infill wall that occurs at the northwest side of the building. Due to the gap and bracing at the top of the wall it is clearly a non-bearing, non- shear wall. No visible cracking could be seen in the masonry walls at any level.

Photo #11:

This photo shows the mechanical penthouse on the roof of the building. The walls appear to line up with the concrete beams and columns below. The penthouse has the same moment frames and gravity framing as the levels below.

Photo #12:

This photo shows the two-story plaza at the northwest side of the building. The typical concrete moment frame stops at the top of the second level with larger concrete frame columns occurring below. The plaza is one- story at the east side of the building and extends to two stories at the west end.

Photo #13:

The area at the middle of the building is open with the stairs and walkway extending through the middle of the building. It appears that this would create a soft story or extreme soft story as defined in Table 12.3-2 of ASCE 7-10. There is potentially a torsional irregularity at the lower level as defined in Table 12.3-1 of ASCE 7-10.

Photo #14:

This photo provides a clear view of the two- story plaza level at the west end. A cross section of the plaza level columns has not been cut to verify the existing reinforcement.

2.2 Overall Structural Condition of Building The structure has been vacant since around 1990. During this time typical maintenance has not been completed. Many of the windows have been broken out allowing the elements into the building. The building has also been occupied by vagrants and animals. The concrete slabs, beams, girders, and columns appear to be in good condition. There was no observable exposed reinforcement in the slabs, beams, girders, or columns except for one location where destructive testing of two columns was completed on the east end of the building. It is clear from the destructive testing and exposed reinforcement that the building does not meet current standards for a lateral force resisting system. The CBC defines substantial structural damage as: 1. In any story, the vertical elements of the lateral force resisting system have suffered damage such that the lateral load-carrying capacity of the structure in any horizontal direction has been reduced by more than 33 percent from its pre-damage condition. 2. The capacity of any vertical gravity load-carrying component, or any group of such components, that supports more than 30 percent of the total area of the structure’s floors and roofs has been reduced more than 20 percent from its pre-damage condition and the remaining capacity of such affected elements, with respect to all dead and live loads, is less than 75 percent of that required by this code for new buildings of similar structure, purpose and location. From the surface it appears that the damage would be considered less than substantial and that repairs and retrofits can be completed to bring the building up to date and code compliant. Damage and testing that has occurred on similar structures since the Northridge and Loma Prieta earthquakes has shown that significant retrofits and alterations would be required to rehabilitate the building to meet the requirements of the current building codes and prevent potentially catastrophic damage and failure of the building’s lateral force resisting system. This would require analysis of the current structure in order to provide retrofit options for the lateral force resisting system. Similar analysis has been provided in the past considering earlier building codes and forces. Deficiencies and potential retrofit are discussed in the following sections.

3.1 Dangerous Building Declarations It is our opinion that the building should be classified as “dangerous” as defined in Section 302 of the UCADB and that abatement should be required. The following is a list of the deficiencies that should be addressed by the building owner. Included is a description of the specific items in the UCADB that would classify this building as “dangerous”. This is not a comprehensive list of non-compliant code items, but a general listing of deficiencies encountered during our brief site visit. The main purpose of our visit was to ensure the structural adequacy of the structure from a life-safety perspective with code-compliant issues being secondary in importance.

1. From a design perspective there are two load conditions that must be considered by a structural engineer. The first of these is the gravity load path which consists of making sure that appropriately sized columns, beams and walls are provided to carry the gravity loads (i.e. persons, partitions, furniture, etc.) from any point in the building down to the foundations. The second

Page 10

2400 CAMINO RAMON, STE 240 SAN RAMON, CA 94583 OFFICE: (925) 275-1700 FAX: (925) 275-0600

condition is the lateral load path which ensures that the building has enough lateral resistance to protect it from a wind or earthquake event. It is evident after walking through the building that there are multiple structural deficiencies/irregularities in the lateral force resisting system. Significant retrofits would be required at all levels of the structure to meet the requirements of the California Existing Building Code (CEBC) and California Building Code (CBC). 2. Section 302 of the UCADB lists eighteen (18) conditions where if any are true would require a building or structure to be deemed “dangerous” and would require the owner to abate those conditions known to be dangerous. It is our opinion that at least three (3) of these conditions are applicable to this structure. The following is a listing of those three definitions as well as a description of why we feel they have been triggered: a. Section 302 – Item 2: “Whenever the walking surface of any aisle, passageway, stairway or other means of exit is so warped, worn, loose, torn or otherwise unsafe as to not provide safe and adequate means of exit in case of fire or panic.” The stairways are open in many instances and littered with debris from improper maintenance of the building. The center stairways and elevator shafts are not passible as they have been used as a trash dump by vagrants that have occupied the building through the years. The structural integrity of the center stair structures could not be verified as the trash made the stairs impossible to observe. b. Section 302 – Item 4: “Whenever any portion thereof has been damaged by fire, earthquake, wind, flood or by any other cause, to such an extent that the structural strength or stability thereof is materially less than it was before such catastrophe and is less than the minimum requirements of the Building Code for new buildings of similar structure, purpose or location.” It has been determined by research and testing that the current construction of this building is unsafe in seismic events. The existing lateral force resisting system - a non-ductile moment frame system - for this structure is no longer an approved system. Provisions for ductile concrete moment frames were added to the 1973 UBC. Significant modifications would be required to rehabilitate the structure to meet current accepted design standards. c. Section 302 – Item 12: “Whenever the building or structure has been so damaged by fire, wind, earthquake or flood, or has become so dilapidated or deteriorated as to become (i) an attractive nuisance to children; (ii) a harbor for vagrants, criminals or immoral persons; or as to (iii) enable persons to resort thereto for the purpose of committing unlawful or immoral acts.” During the site visit it was apparent that the property has been “attractive” for vagrants or other persons. While on site we saw evidence of vagrants which have used the structure for shelter. Evidence of trash and graffiti was seen throughout the site. The city has removed the vagrants and is in the process of cleaning up the structure.

3.2 Structural Deficiencies A structural analysis of the building was conducted by EQE Engineering in February of 1990. At that time EQE determined that key elements of the building were significantly overstressed when considering codes that were in use at the time of the evaluation. The detailing of the structure also provided for little ductility. The high-strength concrete and reinforcement detailing could cause sudden failure of sections of the lateral force resisting system increasing loads to other sections of the building and increasing the likelihood of catastrophic failure. There are also soft story and torsional irregularities at the plaza level. Per Table 12.3-2 of ASCE 7-10 a soft story is defined to exist where there is a story in which the lateral stiffness is less than 70% of that in the story above or less than 80% of the average stiffness of the three stories above. Per Table 12.3-1 of ASCE 7-10 a torsional irregularity is defined as where the maximum story drift, computed including accidental torsion at one end of the structure transverse to an axis is more than 1.2 times the average of the story drifts at the two ends of the structure. These irregularities could serve to magnify lateral forces where these forces are not intended. Collapse of the plaza level is also possible in a seismic event. Three methods for seismic retrofit have been considered as part of our assessment. Although these methods are not the only possibilities they are the most common and have also been considered in the past when conducting evaluation of the building. Method 1 Proposed upgrades include providing structural infill walls between some of the concrete frames at all levels above the plaza. Enough infill would be required to reduce the potential force to the concrete frames to allow ductile failure. Further analysis of the building would be required to determine the required infill and reinforcement to accommodate current lateral forces. However, in-fill walls typically consist of reinforced concrete walls which in turn increase the weight of the structure and the corresponding seismic loading of the structure. Steel braced frames are recommended at the plaza level to account for the soft story and torsional irregularities. A complete structural analysis of the structure would be required to determine the infill framing and braced frame member sizes and anchorage. Additional concrete and reinforcement may be required at the footings to resist the overturning forces at the base where braced frames are added. Method 2 A second analysis was provided by EQE Engineering in March of 1991. This report suggests the use of base isolators and seismic separation joints at the plaza level. Base isolators essentially provide an elastic base that the building would be founded on. The elastic base dampens the seismic forces imparted to the structure above. By providing base isolators at the plaza level the forces to the frames above would be reduced. Although the forces at the upper level would be reduced the existing moment frames as detailed do not meet the ductile concrete moment frame detailing requirements set forth in Chapter 18 of the ACI. It is our opinion that although base isolators would lessen the forces at the upper levels that seismic retrofit of the upper frames would still be required. A preliminary analysis by EQE in 1992 indicates that they gave a 50/50 percent certainty that the structure would provide life safety in a magnitude 6.0 seismic event.

Page 12

2400 CAMINO RAMON, STE 240 SAN RAMON, CA 94583 OFFICE: (925) 275-1700 FAX: (925) 275-0600

Additional analysis of the structure would be required to determine the extent of infill concrete and reinforcement that would be required. Method 3 A third analysis provided by EQE in 1992 provides recommendations for base isolation in conjunction with braced frames at upper levels. This recommendation by EQE falls in line with our concerns that even with base isolation that the building could still sustain significant damage in a seismic event. EQE recommends that braced frames be added from the foundation, all the way to the upper level. The cost of this retrofit at the time of evaluation was higher than the previous two recommendations but would provide a higher likelihood of life safety in a seismic event.

3.3 Hazardous Materials During our site visit we were joined by Tim Cannard, a hazardous materials expert. He indicated that there is asbestos in glues that could be seen on some surfaces as well as ductwork tape and potentially in the concrete from the quarries and pumping equipment. He also indicated that there could be trace amounts of PCB’s, lead, and mercury in the building. The amounts would have to be determined by testing. When determining the demolition process these hazardous materials will have to be considered.

4.1 Demolition Recommendations West Coast Code Consultants does not specialize in demolition. We provide a description of the building to obtain a more accurate bid for demolition services. It is recommended that this information be used to contact demolition contractors that could then provide a more accurate bid for demolition services. The following is a description of the size, construction, materials, and condition of the building. This information was obtained from the detailed analysis of the structure that was conducted by EQE in 1990 and confirmed on our visit to the site on July 9th, 2019. 1. The building is seventy-seven feet, six inches by one hundred seventy-seven feet, six inches and eleven stories tall. The topography of the site slopes from east to west with the entrance to the second level being on the east side. There are several tall, large rooms which occupy the lower level at the west end with smaller mechanical equipment rooms which occupy the lower level at the east end. The east end of the second floor contains the old city council chambers. Large concrete beams support the gravity loading from the columns which occur from the floors above. The third through eleventh floor contain thirty-inch by thirty-inch concrete columns spaced at twenty-five feet on center. These concrete columns support the gravity framing which consist of two concrete girder beams that span the entire structure from east to west with intermediate support being provided by the concrete columns. A 3-1/2” concrete deck is supported by concrete beams spanning north to south. These beams span roughly twenty-five feet and are spaced at an estimated thirty inches on center. There is a mechanical penthouse at the roof level. This penthouse is of similar construction as the typical framing at each level but is contained within the area supported by the columns below (roughly one hundred twenty-five feet by twenty-five feet). Much of the mechanical equipment remains at the penthouse level. This equipment consists of some

Page 13

2400 CAMINO RAMON, STE 240 SAN RAMON, CA 94583 OFFICE: (925) 275-1700 FAX: (925) 275-0600

large machinery. There is a parapet wall which occurs around the outside perimeter of the building which is the same height as the mechanical penthouse. A preliminary cost estimate for demolition of $3,500,000 to $4,500,000 was obtained by contacting multiple demolition companies in the Hayward area. Preliminary estimates for the cost of demolition are much lower than those provided for any of the retrofit solutions. It should be noted that estimates provided for demolition were provided based on a rough description of the size and condition of the building to demolition contractors. The estimate should be verified prior to making any final decisions.

5.1 Cost Estimate Method 1 Preliminary cost estimates for the seismic retrofit of the building were provided by EQE in their 1990 report. EQE estimated the cost for the seismic retrofit at $3.6 million. West Coast Code Consultants came up with a cost estimate of $5.4 million for seismic retrofit. This breakdown can be seen as method one in Appendix ‘A’. Method 2 Initial cost estimates by EQE for Method 2 are $5.6 million for seismic upgrades including the base isolators. Initial cost estimates by West Coast Code Consultants for Method 2 are $7.1 million. This breakdown can be seen as Method 2 in Appendix ‘A’. Keep in mind that this method does not account for the structural fill that would be required at the upper levels. Method 3 takes this into account. Method 3 Initial estimates for Method 3 are $8.7 million. West Coast Code Consultants came up with a cost estimate of $9.7 million. This breakdown can be seen as Method 3 in Appendix ‘A’. To help with cost estimates West Coast Code Consultans also considered FEMA 156, Typical Costs for Seismic Rehabilitation of Existing Buildings. By considering the year of construction, seismic zone, square footage, construction type, seismic system, and inflation rates we were able to come up with a lower and higher bound for the estimated retrofit construction costs. The lower bound for the estimated retrofit costs is $4.1 million. The upper bound for the estimated cost is $11.8 million. Our estimates fall within the bounds of the FEMA cost estimates. Our cost estimates do not account for architectural, mechanical, electrical, fire sprinklers, fire alarms, tenant improvements, disabled accessibility, energy compliance, and plumbing work. These cost estimates are for seismic retrofit only and provide for life safety in a seismic event. Preliminary time estimates for retrofit construction is two years. Estimates for the demolition timeline can be obtained along with bids provided by the demolition contractor. For a more accurate cost analysis destructive testing and bids would be required by an experienced contractor.

6.1 Conclusion It is our opinion that the City should abate the “dangerous” conditions that exist at this site. Section 402 of the UCADB states that abatement should be provided by means of repair, rehabilitation, demolition or removal. It is our opinion that the building is not in eminent danger of collapse. The lateral force resisting system used in construction is no longer an approved system. Significant upgrades to the lateral force resisting system would be required in order to bring the structure up to current code. This would require extensive structural analysis and costly structural upgrades. This would bring the structure up to current code but would not include the cost to complete the finish of the building. New windows, mechanical equipment and ductwork, plumbing, electrical, partitions and interior finishes would be required. New elevators and possibly stairs would be required. All these items would further increase the cost of the finished structure and should be considered when determining what should be done with the building. The extent of the damage should be assessed and the extent of repair required should be determined. In this instance, the City should hire a licensed structural engineer to analyze the building and ensure that an appropriate gravity and lateral load path are provided down to appropriate foundations utilizing a code- accepted lateral force resisting system. Appropriate design drawings and supporting calculations should be provided to the City and a building permit should be obtained prior to commencing any repair work. Initial demolition estimates for the site are much lower than retrofit costs even without considering the cost of finishes. If demolition is determined to be the more desired course of action it is recommended that the building be demolished from the top down in lieu of implosion. Due to the project location as well as hazardous materials that are present in the building implosion would be difficult, expensive, and may not be possible. Prior to demolition hazardous materials should be removed from the building. Bids should be obtained from contractors experienced in the removal of hazardous material and demolition. Please note that this is simply a structural assessment and does not constitute a detailed evaluation of the building. Feel free to contact us at any time should you have any questions or concerns regarding this assessment.

DIRECTIONS TO CONTRACTORS:

The following are directions to contractors by the City of Hayward and this proposal is made with reference to them:

Proposals are required for the entire work. The amount of the proposal for comparison purposes will be the total of all items. The total of unit basis items will be determined by extension of the item price bid on the basis of the estimated quantity set forth for the item.

The contractor shall set forth for each item of work, in clearly legible figures, an item price and a total for the item in the respective spaces provided for this purpose. In the case of unit basis items, the amount set forth under the "Total" column shall be the extension of the item price bid on the basis of the estimated quantity for the item.

In case of discrepancy between an item price in words and the price in figures, the price in words shall prevail. In case of discrepancy between the item price and the total set forth for a unit basis item, the item price shall prevail, provided; however, if the amount set forth as an item price is ambiguous, illegible or uncertain for any cause, or is omitted, or in the case of unit basis items, is the same amount as the entry in the "Total" column, then the amount set forth in the "Total" column for the item shall prevail in accordance with the following:

(1) As to lump sum items, the amount set forth in the "Total" column shall be the item price.

(2) As to unit basis items, the amount set forth in the "Total" column shall be divided by the estimated quantity for the item and the price thus obtained shall be the item price.

All questions concerning proposals are to go to the City Project Engineer designated on the cover of the Specifications, and any changes to the Contract Documents shall be made by addendum.

The contractor’s attention is directed to Section 2, "Proposal Requirements and Conditions," of these special provisions regarding submittal of proposal on City furnished forms.

If this proposal shall be accepted and the undersigned shall fail to contract as aforesaid and to give the two bonds in the sums to be determined as aforesaid, with surety satisfactory to the City of Hayward, within ten (10) days, not including Sundays and legal holidays, after the contractor has received notice from the City of Hayward that the contract has been awarded, the City of Hayward may, at its option, determine that the contractor has abandoned the contract, and thereupon this proposal and the acceptance thereof shall be null and void and the forfeiture of such security accompanying this proposal shall operate and the same shall be the property of the City of Hayward.
