Interest shall be computed at the rate of three times the discount rate on 90-day commercial paper in effect at the Federal Reserve Bank in the Federal Reserve district that includes Oregon on the date that is 30 days after the date when payment was received from the contracting agency or from the contractor, but the rate of interest may not exceed 30 percent.

2.3.4 Notice of any withholding under Article 2.3.3 shall be issued to Subcontractor, with a copy to the public contracting agency, specifying: a) the amount to be withheld; b) the specified causes for the withholding under the terms of the subcontract; and c) the remedial actions to be taken by the Subcontractor in order to receive payment of the amounts withheld.

2.3.5 If Subcontractor fails, neglects or refuses to make payment to a person furnishing labor or materials in connection with the public improvement contract within 30 days after receipt of payment, Subcontractor shall owe the person the amount due plus interest charges commencing at the end of the 10-day period that payment is due under ORS 279C.580 (4) and ending upon final payment, unless payment is subject to a good faith dispute as defined in ORS 279C.580. The rate of interest charged to Subcontractor on the amount due shall equal three times the discount rate on 90-day commercial paper in effect at the Federal Reserve Bank in the Federal Reserve district that includes Oregon on the date that is 30 days after the date when payment was received from the contracting agency or from the contractor, but the rate of interest may not exceed 30 percent. The amount of interest may not be waived.

2.3.6 Subcontractor shall assure that workers of Subcontractor and all of its lower-tier subcontractors shall be paid not less than the specified minimum hourly rate of wage in accordance with law.

Under no circumstances shall Subcontractor pay workers less than the specified minimum hourly rate of wage in accordance with ORS 279C.838 and ORS 279C.840. Subcontractor shall assure that the prevailing wage for the Project is posted in a conspicuous and accessible place in or about the Project. If the prevailing wage requirements also provide for contributions to healthSAMPLE and/or welfare plans, Subcontractor shall assure that a notice remains posted describing the plan(s) in a conspicuous and accessible place in or about the Project. Subcontractor shall submit its Certified Payroll Reports to Contractor (for itself and all lower-tier subcontractors) no later than five (5) working days following the last day of each work week.

2.4.3 To the extent permitted by law, the Alternate Billing Cycle, Extended Payment Provision and Extended Certification Period Provision shall be set forth in the Contract Documents. By the execution of this Subcontract Agreement, Subcontractor expressly consents to any change in such Cycle or Provision subsequent to its bid or proposal as is provided in this Subcontract Agreement or the Contract Documents.

2.5 Any billing or estimate submitted by Subcontractor under this Subcontract Agreement shall be in strict accordance with the provisions of this Subcontract Agreement, shall be in the form and detail prescribed by Contractor, shall be accompanied by appropriate notarized waivers of any bond, construction, mechanic’s or materialman’s lien from Subcontractor and from each person performing labor or supplying materials, products, equipment or services used in the Work, and shall be personally certified by Subcontractor’s principal executive officer, evidenced by his or her signature and notarized verification, that-

(c) based on such officer’s knowledge, the billing or estimate fairly present in all material respects the amount due and unpaid to Subcontractor as of the date stated.

Such certification is mutually agreed to be a material provision of this Subcontract Agreement.

2.6 Nothing in this Subcontract Agreement shall obligate Contractor to pay or to request payment for amounts withheld by the Owner, unsatisfactory work progress, defective construction work, materials or products not remedied, or disputed work, materials or products, nor in the even of Subcontractor’sSAMPLE failure to comply with material provisions of this Subcontract Agreement or the Contract Documents, third party claims filed or which may be filed relative to the Work.

Page 7 Griffin Construction Subcontract

days in advance of the monthly date set forth in the Contract or Contract Documents, Contractor may estimate the value thereof.

2.8 The determination made by Owner or its representative of quantities of the Work performed and to be paid for shall be binding and conclusive, and shall conclusively establish the amount of the Work done by Subcontractor. No compensation shall be paid Subcontractor for work not approved, accepted and paid for by Owner and Subcontractor will make no claims against Contractor based on any estimates or calculations other than those made by Owner and for which payment has been made by Owner to Contractor. It is specifically agreed that Contractor’s actual receipt of payment from the Owner for Subcontractor’s work is a necessary condition precedent to any and all partial and final payments by Contractor to Subcontractor.

2.9 Subcontractor shall make prompt payment to all its sub- subcontractors and material suppliers, and to persons performing labor or furnishing materials or equipment used or to be used in the performance of the Work. Subcontractor shall defend and indemnify Contractor, its sureties and representatives, from any claim or demand alleging Subcontractor’s failure so to do, or the failure of any of Subcontractor’s sub-contractors at any tier so to do, expressly including any interest, costs or attorneys fees which may be claimed or awarded. No moneys shall be deemed as earned or owing until Subcontractor has paid all obligations incurred for labor, materials, supplies, equipment and any other obligations incurred in performance of the Work, or which may become claims against Contractor’s bond or may become liens against Contractor’s earning or against the property or improvements of the Project. Any portion of the Price unpaid, whether upon partial payments or final payment, may be considered as held by Contract in trust for the benefit of any laborer, materialman or other creditor and Contractor reserves the right, prior to making any partial payment or final payment to request and receive from Subcontractor a certification under oath, and such other evidence as Contractor may request, that all obligations incurred by or on behalf of Subcontractor which are or may become such clam or lien have been paid, and Subcontractor’s written waiver of any claim or lien to the extent of such payment.

2.10 Upon the completion and acceptance of the Project and payment therefore in full by Owner, Subcontractor will be paid the remaining amount due Subcontractor under this Subcontract Agreement, to the extent of Owner’s payment to Contractor forSAMPLE the Work. All prior payments shall be subject to correction in the final payment.

2.11 It is specifically understood and agreed that Contractor is not an insurer or guarantor of the amount or nature of the Work and that quantities of the Work are approximate only, Owner and Contractor expressly reserving the right to add to or subtract from the amount thereof and to make changes therein. Subcontractor shall be bound thereby to the same extent

Page 8 Griffin Construction Subcontract

that Contractor is bound thereby. No adjustment in the Price shall be made unless Owner adjusts said price with Contractor and makes payment therefore to Contractor. Subcontractor shall not be entitled to damages for delays by reason of any act of Owner, unless and until Owner compensates Contractor for Subcontractor’s damages, and Subcontractor’s sole remedy for such delay shall otherwise be an extension of time, if granted by Owner. Subcontractor shall not be entitled to recover damages from Contractor for delays or damaged caused by the act or omission of any other subcontractor, nor shall Subcontractor be liable to Contractor for delays occasioned by the act or omission of any other subcontractor of Contractor, unless and until such other subcontractor compensates Contractor for Subcontractor’s damages.

Where appropriate, Subcontractor shall utilize a blanket resale certificate. Where Subcontractor has not utilized a resale certificate but has paid tax on a purchase of articles that are subsequently sold at retail in connection with Subcontractor’s performance of the Work, the Subcontractor shall not Contractor the sales tax paid by the Subcontractor. Subcontractor shall include a provision similar to the foregoing in all subcontracts and purchase orders issued by it in connection with the performance of the Work.

Contractor shall not be responsibly to Subcontractor for any act, omission or damage caused to Subcontractor by any such other entity, including Contractor’s other subcontractors. In the event Subcontractor is delayed by any cause beyond its control, Subcontractor is entitled to an extension of its scheduled time of performance to the same extent Contractor actually receives from Owner an extension of the Contract time and performance for Subcontractor’s Work, provided Subcontractor shall have timely provided to Contractor all necessary notice and evidence required by the Contract Documents. Subcontractor shall not be entitled to any other remedy, cost, damage or adjustment on account of delay.

3.4 If any portion of the Work depends upon prior performance of any other work by Contractor or its other subcontractor, Subcontractor, by commencing such portion of the Work, accepts the adequacy and completeness of such other work.

3.5 Subcontractor shall comply with instructions given by Owner or its representatives, or by Contractor, including any instructions to suspend or delay the performance or completion of the Work or any portion thereof. Subcontractor shall be entitled to an adjustment of the Price or of the time of performance only to the extent that Contractor actually receives from Owner an adjustment of the amount paid to Contractor or an adjustment of the time of performance under the Contract or Contract Documents as a result of such instruction.

The Wallace Group, Inc., (Wallace Group) has completed a geotechnical engineering exploration for the proposed Avion Water Office Building located in southeast Bend, Oregon (Figure 1, Vicinity Map). A figure with exploration locations is shown on Figure 2, Exploration Location Map.

Based on discussions with the Client, and review of preliminary plans provided by Neal Huston & Associates (project Architect), dated October 3, 2019, we understand the proposed improvements include construction of a new office building. The new building and associated improvements will be constructed on a parcel of land located south of and adjacent to the existing Avion Water Company’s office building. We understand once the new office building is completed, the existing facility will be refurbished for use as a shop facility. The new office will be approximately 9,000 square feet, single-story, timber-framed, and have exposed and polished concrete slab floors. Other improvements will include underground utility infrastructure installation, updated access drives and parking areas, stormwater collection and disposal, and landscaping.

Subsurface explorations generally encountered fill materials and native silty-sand soil underlain by shallow basalt bedrock in the areas explored. The depth to basalt bedrock ranged from approximately 1 to 11 feet below ground surface (bgs). The proposed development area is currently covered with boulder fill deposits from historical nearby developments. Underlying a surficial layer of topsoil, the fill materials typically consisted of a silty-sand-with-gravel, cobble and boulder matrix. Boulders up to 4-feet in diameter were encountered within the fill materials. The fill materials extended up to 4-feet bgs and were underlain by native silty-sand and weathered-in-place basalt bedrock that typically classifies as silty-sand-with-gravel. The hard basalt bedrock caused refusal to excavation with the excavator and will require hydraulic hammering to excavate for the proposed developments.

Based on this exploration, the site appears suitable for the proposed development from a geotechnical perspective, provided the recommendations contained in this report are incorporated into design and construction.

1.1 GENERAL The Wallace Group, Inc., (Wallace Group) completed a geotechnical engineering exploration for the proposed Avion Water Office Building in southeast Bend, Oregon (Figure 1, Vicinity Map). A figure with exploration locations is shown on Figure 2, Exploration Location Map.

1.2 PROJECT DESCRIPTION Based on discussions with the Client, and review of preliminary plans provided by Neal Huston & Associates (project Architect), dated October 3, 2019, we understand the proposed improvements include construction of a new office building. The new building and associated improvements will be constructed on a parcel of land located south of and adjacent to the existing Avion Water Company’s office building. We understand once the new office building is completed, the existing facility will be refurbished for use as a shop facility. The new office will be approximately 9,000 square feet, single-story, timber-framed, and have exposed and polished concrete slab floors. Based on preliminary information from Parametrix (project Civil Engineer), we anticipate the finished floor elevation will be approximately 3,846.75 feet mean sea level (msl). Other improvements will include underground utility infrastructure installation, updated access drives and parking areas, stormwater collection and disposal, and landscaping.

1.3 PURPOSE AND SCOPE OF SERVICES The purpose of this exploration was to evaluate general subsurface conditions within the development areas in order to provide recommendations for foundation design and other geotechnical aspects related to site development. Our scope of services included the following tasks:  Review regional and project area geology;  Explore subsurface conditions with backhoe test pits and perform penetration testing on shallow soil using a Dynamic Cone Penetrometer;  Perform engineering analyses and develop recommendations for foundations, floor slabs, site preparation, excavations, grading, pavement design, and site seismicity; and  Prepare this geotechnical report summarizing our findings, conclusions, and recommendations.

2.1 SUBSURFACE EXPLORATION Subsurface conditions were explored on January 27, 2020. Eight (8) test pits, designated TP-01 through TP-08, were excavated to depths ranging from approximately 1 to 11 feet bgs. Test pits were excavated with a CAT 311 excavator operated by Terry Shine Excavation of Bend, Oregon. A Wallace Group geotechnical professional logged the test pits, performed Dynamic Cone Penetrometer (DCP) testing, and visually classified the materials encountered. The test pit logs, located in Appendix A, describe the materials encountered at each location explored. The soil and bedrock types between explorations are anticipated to be similar; however, some variation should be expected. The stratigraphic contacts indicated at each point of exploration represent the approximate boundaries between soil and bedrock types. The approximate locations of the test pits are shown on Figure 2.

A more complete description of the sampling techniques and soil classification terminology is presented in Appendix A.

Soil samples were transported to our Bend geotechnical laboratory where they were visually classified and prepared for laboratory analysis. Laboratory tests were conducted in general accordance with standard procedures and included the following:

 Moisture Content, ASTM D2216  Gradation Analyses, ASTM C117 / C136  Classification of Soil for Engineering Purposes, ASTM D2487

Laboratory test results are included in Appendix B.

4.1 SURFACE Currently, the proposed development area is substantially undeveloped. Portions of the development area appear to be currently used by the Client for vehicle parking. The remainder of the site supports mature ponderosa pines and native grasses and shrubs. Based on the topographic survey completed by Parametrix, dated January 22, 2020, the site appears to be relatively level with exception of boulder stockpiles that are located within the proposed building footprint. The boulder stockpiles are up to approximately 4-feet tall in some locations. Elevations across the development area range from approximately 3,841 to 3,846 feet mean sea level (msl).

4.2 SUBSURFACE CONDITIONS Subsurface explorations generally encountered organic topsoil, fill materials, and native soil over shallow basalt bedrock in the areas explored. The depth to basalt bedrock ranged from approximately 1 to 11 feet below ground surface (bgs). Underlying the organic topsoil, the fill materials typically consisted of a silty-sand with gravel, cobble and boulder soil matrix. The fill material extended up to 4-feet bgs and was underlain by native silty-sand, silty-gravel-with- sand and weathered-in-place basalt bedrock. In several locations the native silty-sand was highly pumiceous. All excavations encountered refusal on hard basalt bedrock and basalt boulders with the CAT excavator.

4.2.1 Fill Materials All exploration locations encountered existing, undocumented fill materials extending from the surface up to 4-feet bgs. The existing fill materials consisted of silty-sand with gravel, cobble and boulder soil matrix. Boulders up to 4-feet in diameter were encountered within the fill matrix. The soil matrix was moist, brown, and contained fine to coarse-grained sand and gravel. Based on DCP testing, the density of fill materials are variable and range from loose to dense.

4.2.2 Silty-Sand and Silty-Gravel-with-Sand All explorations encountered native silty-sand and silty-gravel-with-sand below the fill materials. The native silty-sand and silty-gravel-with-sand extended to depths ranging from 2½ to 11-feet bgs in the areas explored and was underlain by basalt bedrock. In several locations, the silty-sand soil was highly pumiceous and light brown to tan. Near the contact point with the basalt bedrock surface, the soil contained more gravel-sized fragments and was slightly cemented. This is typical of weathered-in-place basalt that is present near the soil and bedrock

TWG20R010 Page 4 of 17 February 14, 2020

62915 NE 18th St, Ste 1, Bend, OR 97701 p | 541.382.4707 f | 541.383.8118 wallacegroup-inc.com contact. The silty-sand and silty-gravel is slightly moist to moist, brown to light tan, and fine- to coarse-grained. DCP testing indicates the silty-sand and silty-gravel is loose.

Gradation tests indicate the native soil generally classifies as silty-sand (SM) and silty-gravel (GM), according to the USCS. The native soil samples contained between 16.4 and 23.4 percent clay- and silt-sized particles. Moisture content of the native soil ranged from 8.3 to 24.0 percent.

4.2.3 Basalt Bedrock Basalt bedrock was encountered beneath the native silty-sand and silty-gravel-with-sand in all test pits. Where encountered, the depth to basalt bedrock ranged from 1 to 11 feet bgs. The CAT 311 excavator encountered refusal on competent basalt bedrock, which typically requires drilling and blasting, or hydraulic hammers to remove. Competent basalt bedrock exhibits negligible settlement under the anticipated tank loads. The unconfined compressive strength of competent basalt bedrock typically ranges from 3,000 to 8,000 pounds per square inch (psi), based on core samples collected at other nearby locations.

4.3 GROUNDWATER Groundwater was not encountered in the explorations and should not influence site development. Localized perched water may occur at the soil/basalt interface during wet periods. A review of well logs obtained from the Oregon Water Resource Department indicates groundwater level is at least 300 feet bgs in the project area.

5.1 REGIONAL AND SITE GEOLOGY The site is located within the High Lava Plains Physiographic Province of central Oregon, near the adjacent Cascade Range foothills to the west. This relatively young volcanic region is characterized by a multitude of volcanic cones and buttes, lava flows, and lava tubes. The region exhibits moderate topographic relief and is relatively smooth in nature. The region exhibits a poorly developed drainage network with few canyons and gullies because of central Oregon’s location in the rain shadow formed by the Western and High Cascade Mountains. Yearly precipitation averages between 8 and 15 inches. Except for isolated lake (lacustrine) sediments and fluvial deposits, most of the rocks in the province are volcanic, and thick accumulations of basaltic lava and welded tuff are common. The underlying rock formation mapped at the project site is the Pleistocene era Basalt of Newberry volcano.

Seismically, the project site is in a northwest-trending zone of en echelon faults that parallel the High Cascade Mountain Range. These structural features extend northward from a convergence zone at Newberry Volcano and are generally referred to as the Sisters Fault Zone. This zone includes the Tumalo, Rimrock, Black Butte, and Green Ridge Faults and may represent a structural transition between the Brothers and Metolius Fault zones (Geomatrix, 1995), or mark the eastern boundary of the High Cascades Graben (Taylor, 1981). The nearest fault is roughly traced approximately ¼ mile east of the project. This is the Rimrock-Tumalo section of the Metolius Fault Zone. Generally, this section of the Metolius Fault Zone is thought to be last active during the Middle and Late Quaternary, and less than 750,000 years old (USGS, 2019).

5.2 SEISMIC DESIGN CRITERIA Central Oregon lies in an area of low to moderate seismic risk. The 2019 Oregon Structural Specialty Code (OSSC), based on the 2018 International Building Code (IBC), requires that structures be designed to sustain the maximum considered earthquake.

Based on subsurface explorations at the project site, we anticipate the finished subgrade for the development will be underlain by less than 10 feet of native silty-sand and gravel or structural fill. Hard basalt bedrock will typically be located at a depth less than 10 feet bgs within the building footprint. The overburden soil and basalt bedrock will not be liquefiable during earthquakes. Other seismically related hazards, including lateral spreading, landslides are not applicable for this project. Based on our evaluation of the soil and rock encountered in the explorations and other published geologic information, we recommend the seismic soil

62915 NE 18th St, Ste 1, Bend, OR 97701 p | 541.382.4707 f | 541.383.8118 wallacegroup-inc.com profile for the upper 100 feet beneath the site be considered a ‘Rock’ profile. The associated Site Class is defined as B. Related seismic design criteria are presented in Appendix C. Based on our understanding, the building does not classify as a “Special Occupancy Structure” or “Essential Facility” per Chapter 18 of the Oregon Structural Special Code (OSSC).

62915 NE 18th St, Ste 1, Bend, OR 97701 p | 541.382.4707 f | 541.383.8118 wallacegroup-inc.com 6.0 CONCLUSIONS AND RECOMMENDATIONS

Based on the results of field exploration, laboratory testing, engineering analyses and our local experience, it is our opinion that the site is suitable for development from a geotechnical perspective, provided the recommendations presented in this report are incorporated into design and construction.

6.1 EXCAVATIONS AND GRADING Based on preliminary information provided by the project Civil Engineer, we anticipate an approximate finished floor elevation (FFE) of 3,846.75 feet msl. Based on this information, we anticipate cuts of approximately 3-feet will be required to remove fill materials and native soil to expose basalt bedrock and native soil below foundation elements. Site grading and utility trench excavations will be made into fill materials, native silty-sand, and basalt bedrock. The native soil and fill material can be excavated with conventional earth-moving equipment such as backhoes, excavators, and bulldozers. The hard basalt rock is generally competent to fractured and will likely require drilling and blasting or hydraulic-hammer chipping to remove. Utility trench installations will likely encounter bedrock that will need to be removed.

Basalt bedrock, excavated with hydraulic hammers, would be classified as “stable rock” when applying OSHA excavation guidelines. Typically for permanent slopes, competent basalt may be cut at a slope not exceeding ½: 1 (H:V). Basalt rock that is fractured or excessively disturbed by blasting may require classification as “Type B” material and would require slopes not exceeding 1:1 (H:V). Native silty-sand should be classified as “Type C” material. Temporary slopes in native silty-sand should not exceed 1½ :1 (H:V). Groundwater will not influence subgrade, utility or foundation excavations.

6.1.1 Site Preparation We recommend that all existing fill materials are removed from development areas. Below foundation elements, all fill material should be removed to expose native soil or basalt bedrock. Where shallow basalt bedrock is present at the bottom of footing elevations, we recommend over-excavation of 6-inches and replacement with compacted aggregate base course (ABC).

After removal of unsuitable materials as noted above, the subgrade in the building pad, parking, and access drive areas should be proof-rolled with a loaded 10-cubic-yard dump truck, or full 4,000-gallon water truck, to confirm subgrade stability prior to placing new fill. Any deflection observed during proof-rolling should be addressed. If unstable (“pumping”) soil is

TWG20R010 Page 8 of 17 February 14, 2020

62915 NE 18th St, Ste 1, Bend, OR 97701 p | 541.382.4707 f | 541.383.8118 wallacegroup-inc.com observed in isolated areas, remedial measures may consist of further compaction, including moisture-conditioning (aeration), or over-excavation and replacement with granular, structural fill. Pumping soil conditions are more common when site preparation occurs during spring and after periods of prolonged precipitation. Wallace Group should be consulted to observe proof- rolls and subgrade bearing conditions prior to placing structural fill or concrete forms.

With slight risk of post-construction settlement, the owner may choose to remove only the upper 1-foot of existing fill material within proposed parking and access drive areas and replacement with compacted ABC. Preparation of subgrade should be in accordance with recommendations provided above.

6.1.2 Structural Fill Materials and Placement Where structural fill is needed to raise grades beneath load-bearing elements, such as floor slabs, footings, and paving areas, we recommend it consist of appropriately-graded sand and gravel having 100 percent passing a two-inch sieve, less than 30 percent retained on the ¾-inch sieve, and less than 20 percent passing a No. 200 sieve. On-site, non-organic, native soil, fill material, and excavated basalt from cut areas should be suitable for re-use as structural fill after processing and proper moisture-conditioning, provided it meets the specifications provided in Table 6.1.2. We recommend structural fill below footings, and within their zone of influence, have a maximum dry density (ASTM D1557) of at least 90 pcf.

In addition, we recommend:  Structural fill be moisture-conditioned to within a range of +/- 2 percent to optimum moisture content, placed in 8-inch loose lifts, and compacted as recommended in Table 6.1.2, Engineered Fill Specifications Summary.  Structural fill should not be placed during freezing weather or on frozen subgrade to avoid potential thaw settlement.  Wallace Group periodically observes the fill placement and tests the fill for grain-size and compaction. Table 6.1.2, below, summarizes the placement and compaction specifications for anticipated uses of structural fill for this project.

6.2 FOUNDATIONS We recommend the proposed office building foundation elements are supported on conventional cast-in-place concrete spread footings. Where shallow basalt bedrock is present at the bottom of footing elevations, we recommend over-excavation of 6-inches and replacement with compacted ABC. Footings bearing on properly compacted ABC and native soil should be

TWG20R010 Page 10 of 17 February 14, 2020

62915 NE 18th St, Ste 1, Bend, OR 97701 p | 541.382.4707 f | 541.383.8118 wallacegroup-inc.com designed for a maximum allowable bearing pressure of 2,000 pounds per square foot (psf). The following criteria should also be incorporated into project plans and specifications:  Exterior footings should bear below frost depth. A minimum foundation burial depth of 18 inches is required for frost protection.  The bottoms of footings should be compacted with suitable compaction equipment, such as a jumping jack or vibrating plate connected to an excavator.  Continuous strip footings should be at least 12 inches wide. Isolated pad footings should be at least 18 inches square.  Expected settlement of footings bearing on up to 10 feet of soil, underlain by basalt bedrock will be up to ¾-inch.  The allowable bearing pressure can be increased by 1/3 for temporary loads such as wind and seismic.  Structural fill and ABC placed beneath footings should be compacted to 95 percent of modified Proctor density, ASTM D1557.  Placement and compaction of structural fill should be observed and/or tested on a part- time basis by a Wallace Group technician working under the direction of a professional engineer.  The ultimate coefficient of sliding resistance between the concrete and bearing materials is 0.47. A factor of safety against sliding greater than 1.5 is considered acceptable if passive resistance is ignored. If passive resistance is included in sliding resistance a factor of safety greater than 2.0 should be used.

6.3 FLOOR SYSTEMS AND EXTERIOR FLATWORK Native soil and structural fill will likely be exposed at slab subgrade level for the new office building. The compacted native soil and new structural fill will provide adequate support for floor slabs if they are placed, compacted and prepared in accordance with Section 6.1.1 – Site Preparation. Structural fill below interior slab on grade should be compacted to 95 percent of ASTM D1557 as indicated in Table 6.1.2, Engineered Fill Specifications Summary.

We recommend a minimum of 6 inches of crushed ABC be placed beneath interior slabs-on- grade. The base course should comply with the specifications shown in Table 6.1.2, Engineered Fill Specifications Summary, and be compacted to 95 percent of ASTM D1557. If more than six inches of material is needed to establish bottom-of-slab level, either additional base course or structural fill, compacted to 95 percent of ASTM D1557, can be used to raise the subgrade level. A modulus of subgrade reaction of 125 pounds per cubic inch (pci) should be used for slab thickness design.

62915 NE 18th St, Ste 1, Bend, OR 97701 p | 541.382.4707 f | 541.383.8118 wallacegroup-inc.com Light-duty concrete flatwork, such as sidewalks, should be underlain by a minimum of 4 inches of crushed aggregate leveling course compacted to at least 92 percent of ASTM D1557. Structural fill beneath light duty exterior slabs and sidewalks should be placed in lifts not exceeding eight inches thick. All organic material, including roots larger than ½-inch in diameter, and other deleterious material exposed at slab or sidewalk subgrade elevations should be removed to firm, unyielding native soil and replaced with structural fill.

The native soil has low to moderate frost heave potential in their present moisture condition. However, if a source of moisture becomes present, the soil would exhibit some frost heave. Exterior slabs could heave on the order of ½-inch if the silty-sand subgrade soil was saturated and sub-freezing temperatures occurred. The most effective and economical method to control frost heave is provision for adequate drainage of surface runoff away from development areas and other foundation elements.

6.4 DRAINAGE CONSIDERATIONS Foundation and slab performance will be influenced by drainage conditions around the perimeter of the proposed structure. Adequate drainage should be provided and maintained throughout the life of structure and water must not be allowed to infiltrate below the foundation. We recommend the ground surface be sloped to drain surface water away from the development areas without ponding. The ground surface adjacent to foundation should be sloped away from the foundation at least 5 percent in landscaped areas and 2 percent in hard- surfaced areas. This site is underlain by shallow basalt bedrock which will inhibit stormwater infiltration. Perched water should be anticipated at the soil and basalt interface during wet seasons. Adequate surface sloping will help to direct water away from the foundation.

6.5 PAVEMENT RECOMMENDATIONS 6.5.1 Parking Areas and Access Drives We anticipate that traffic will likely consist of light automotive and moderate-duty service vehicles. Traffic during construction will consist of heavier vehicles with higher wheel loads and precautions should be taken to prevent damage to any newly constructed pavement.

In our opinion, the proof-rolled inorganic native granular soil and properly compacted new structural fill will provide adequate subgrade support for asphalt or concrete-paved areas associated with the development. Additionally, if the upper 1-foot of existing undocumented fill is removed in parking and access drive areas, and the subgrade is properly prepared, we anticipate sufficient adequate support for paved areas. Proper roadway section drainage,

62915 NE 18th St, Ste 1, Bend, OR 97701 p | 541.382.4707 f | 541.383.8118 wallacegroup-inc.com including site drainage to avoid ponding of water adjacent to roadway areas, will aid in reducing the potential for pavement distress. Structural fill in paved areas should consist of processed on-site native soil, or imported sand and gravel meeting the requirements of Table 6.1.2, Engineered Fill Specifications Summary. Parking and access drive subgrade fill should be placed in maximum 8-inch lifts, loose thickness, moisture-conditioned, and compacted to at least 92 percent of ASTM D1557.

Based on the project soil conditions and assumed traffic loads for asphalt-paved parking and access drives, we recommend a pavement section of 3-inches of Asphaltic Concrete (AC) underlain by 6-inches of crushed ABC. Concrete pavement, if constructed, should consist of a minimum of 6-inches of concrete underlain by 8-inches of ABC. Concrete pavement is recommended for areas with heavy anticipated wheel loads, such as trash enclosures.

6.5.2 Asphalt Pavement Material Specifications The AC should be dense-graded, hot mix asphalt concrete (HMAC) as specified in ODOT Section 00745 plus the following supplemental specifications for density testing:

 The HMAC mix design for the roadways should be Level 2.  The asphalt binder should be PG 64-28, or as specified by the Civil Engineer.  The ABC should be ¾-inch minus, dense graded aggregate as specified in ODOT Sections 00641 and 02630.10.  Road-mixed ABC is permitted per Section 00641. Road-mixed ABC allows water to be added on-site for compaction vs. pug-milled materials processing.  The HMAC should be compacted to a minimum of 92 percent of the Rice theoretical maximum density. The ABC should be compacted to a minimum of 92 percent of ASTM D1557.

Supplemental Specifications for Density Testing: The roadway AC and ABC should be field tested for in-place density. Density test frequency should be based on a “roll-pattern” or Standard City of Bend procedures.

APPENDIX A

APPENDIX A FIELD EXPLORATION SUMMARY GENERAL Subsurface conditions for the Avion Water Office Building project located in Bend, Oregon, was explored by excavating 8 test pits (designated TP-01 through TP-08), at the approximate locations shown on Figure 2 , Exploration Location Map. Test pit logs are included in this appendix. The test pit explorations were performed on January 27, 2020. The procedures used to excavate the test pits, and collect soil samples, and other field techniques are described in detail in this appendix. Unless otherwise noted, all soil sampling and classification procedures followed local engineering practices which are in general conformance with relevant ASTM procedures and the Unified Soil Classification System (USCS). “General conformance” means that certain local and common excavation and descriptive practices and methodologies have been followed.

TEST PITS Eight (8) test pits were excavated with a CAT 311 excavator operated by Terry Shine Excavation, of Bend, Oregon. The excavator bucket was 24 inches in width and equipped with conventional spade teeth. The test pits were observed by a Wallace Group geotechnical professional who maintained a detailed log of subsurface conditions and materials encountered, collected soil samples at appropriate depth intervals, and documented excavation backfilling. The test pits were excavated to depths ranging between approximately 1 to 11 feet below ground surface (bgs). Bulk samples were retrieved for laboratory testing. Test pit locations should be re- excavated during construction and backfilled in accordance with Section 6.1.2 -Structural Fill Materials and Placement.

Dynamic Cone Penetration (DCP) testing was conducted to evaluate the relative density of the soil. DCP procedures are generally described in ASTM Special Technical Publication 399, which have been modified by Wallace Group to provide better representation of soil relative density or stiffness. During the DCP test, a 1.5-inch diameter steel cone is driven up to 18 inches into the soil using a 15-pound hammer dropped from a height of 18 inches. The number of blows is recorded and can be roughly correlated to the Standard Penetration Test. The number of blows required to drive the cone 12 inches into the soil provides a measure of the relative density of granular soils such as sand and gravel, and the strength of cohesive soils.

SAMPLING Disturbed soil samples were retrieved from the test pits. The samples were classified and sealed in plastic bags for further examination and physical testing in our laboratory for gradation and moisture content.

TWG20R010 Page 1 of 8 February 14, 2020

TEST PIT LOGS Figure A is a Legend explaining the information and symbols presented on the test pit logs. The logs of the test pits are presented on Figures A-1 through A-8. The logs describe the materials encountered and the depths where materials and/or characteristics of these materials changed, although the changes may be gradual. Where material types and descriptions changed between samples, the contacts were interpreted. On each test pit, the types of samples collected (including their identification number) are reported, including laboratory test results and DCP blow counts.

MATERIAL DESCRIPTIONS Soil samples were visually classified in the field as they were collected. Consistency, color, relative moisture, degree of plasticity, and other distinguishing characteristics of the samples were noted. Afterwards, the samples were re-examined in the laboratory, various standard classification tests were conducted, and the field classifications were modified where necessary. The terminology used in the soil classifications and rock descriptions are defined beginning on Page 3 and are included under material description on each log.

GROUNDWATER Groundwater was not encountered during subsurface exploration for this project.

TERMINOLOGY USED TO DESCRIBE SOIL AND ROCK SOIL DESCRIPTIONS Soils exist in mixtures with varying proportions of components. The predominant soil, i.e., greater than 50 percent based upon total dry weight, is the primary soil type and is capitalized in our log descriptions, e.g., SAND, GRAVEL, SILT or CLAY. Lesser percentages of other constituents in the soil mixture are indicated by use of modifier words in general accordance with the Visual-Manual Procedure (ASTM D2488-93). “General Accordance” means that certain local and common descriptive practices have been followed. In accordance with ASTM D2488, group symbols (such as GP or CH) are applied on that portion of the soil passing the 3-inch (75mm) sieve based upon visual examination. The following describes the use of soil names and modifying terms used to describe fine- and coarse-grained soils.

Fine - Grained SOILS (More than 50% fines passing 0.074 mm, #200 sieve) The primary soil type i.e. SILT or CLAY is designated through visual – manual procedures to evaluate soil toughness, dilatancy, dry strength, and plasticity. The following describes the terminology used to describe fine - grained soils and varies from ASTM 2488 terminology in the use of some common terms.

Primary soil NAME, adjective and symbols Plasticity Plasticity Description Index (PI) ORGANIC SILT CLAY SILT & CLAY ML & MH CL & CH OL & OH SILT Organic SILT Non-plastic 0 - 3 SILT Organic SILT Low plasticity 4 - 10 Clayey SILT Silty CLAY Organic clayey SILT Medium >10 – 20 Plasticity Clayey SILT CLAY Organic silty CLAY High Plasticity >20 – 40 Clayey SILT CLAY Organic CLAY Very Plastic >40

Modifying terms describing secondary constituents, estimated to 5 percent increments, are applied as follows: Description % Composition Trace sand, trace gravel 5% - 10% With sand; with gravel 15% - 25% Sandy, or gravelly 30% - 45%

TWG20R010 Page 3 of 8 February 14, 2020

Borderline Symbols , for example CH/MH, are used where soils are not distinctly in one category or where variable soil units contain more than one soil type. Dual Symbols, for example CL-ML, are used where two symbols are required in accordance with ASTM D2488.

Soil Consistency. Consistency terms are applied to fine-grained, plastic soils (i.e., PI > 4). Descriptive terms are based on direct measure or correlation to the Standard Penetration Test N-value as determined by ASTM D1586-84, as follows.

Unconfined Compressive Strength Consistency Term SPT N-value Tons/sq.ft. kPa Very soft Less than 2 Less than 0.25 Less than 24 Soft 2 - 4 0.25 - 0.5 24 - 48 Medium stiff 5 - 8 0.5 - 1.0 48 – 96 Stiff 9 - 15 1.0 - 2.0 96 – 192 Very stiff 16 - 30 2.0 - 4.0 192 – 383 Hard Over 30 Over 4.0 Over 383 Note: For SILT with low to non-plastic behavior, (i.e., PI < 4) a relative density description is applied.

Coarse-Grained Soils (less than 50% fines) Coarse-grained soil descriptions, i.e., SAND or GRAVEL, are based on that portion of materials passing a 3-inch (75mm) sieve. Coarse-grained soil group symbols are applied in accordance with ASTM D2488 based upon the degree of grading, or distribution of grain sizes of the soil. For example, well graded sand containing a wide range of grain sizes is designated SW; poorly graded gravel, GP, contains high percentages of only certain grain sizes. Terms applied to grain sizes follow.

Particle Diameter Inches Millimeters Sand (S) 0.003 - 0.19 0.075 - 4.8 Gravel (G) 0.19 - 3.0 4.8 - 75 Add itional Constituents Cobble 3.0 - 12 75 - 300 Boulder 12 - 120 300 - 3050 Rock Block >120 >3050

The primary soil type is capitalized, and the amount of ‘fines’ in the soil are described as indicated by the following examples. Other soil mixtures will provide similar descriptive names.

TWG20R010 Page 4 of 8 February 14, 2020

Example: Coarse-Grained Soil Descriptions with Fines 10% fines 5% fines (Dual Symbols) 15% to 45% fines GRAVEL with trace silt: GW or GP GRAVEL with silt, GW-GM Silty GRAVEL: GM SAND with trace clay: SW or SP SAND with clay, SP-SC Silty SAND: SM

Additional descriptive terminology applied to coarse-grained soils follow.

Coarse-Grained Soil Containing Secondary Constituents Clean < 5% fines With sand or with gravel 15% - 25% sand or gravel Sandy or gravelly 30% - 45% sand or gravel With cobbles; with boulders Any amount cobbles or boulders. Additional terms may be used to describe amount including abundant, scattered.

Cobble and boulder deposits may include a description of the matrix soils, as defined above.

Relative Density terms are applied to granular, non-plastic soils based on direct measure or correlation to the Standard Penetration Test N-value as determined by ASTM D1586. Relative Density Term SPT N-value Very loose 0 - 4 Loose 4 - 10 Medium dense 10 - 30 Dense 30 - 50 Very dense > 50
