re: Historic Considerations Review Replace Roofing – Woodbury Branch Library

Kathy:

The roofing systems on the high slope portions of the Woodbury Branch Library are to be removed as part of a City and County of Denver FIT Project. The eastern portion of the building is one of the original Carnegie Libraries built in the Denver area. As such, this structure is on the Landmark Preservation Commission’s list of historic places. Because of this, the roofing replacement design for this building needs to be reviewed by the Commission. This letter report has been prepared to address the historic aspects of the new high slope tile roofing system.

Roof Type

The high slope roofs on the library are identical in color and type. The west portion of the building consists of an addition to the main building. There is a small tile roof on this addition that is to be replaced at the same time as the tile on the original structure. At both clay tile covered high slope roof decks relatively new 0.75” thick Ludowici one piece 13.25” Mission clay tile roofing has been installed. The color blend has a primary tile that has an orange/red color. The highlight tiles are dark brown and tan.

The proposed new tile will be the 0.75” thick Mission one piece tile offered by Ludowici. A product sheet is attached that shows the tile and provides its dimensions. The new tile pieces are of the same dimension as the tile roofing to be replaced. The tile will be formed from the same clay mix type as the original tile that were placed on the older library roofs.

Tile Color

Both tile roofs will be removed as part of the project. When the tile roofing is replaced, the design documents will indicate the new colors to be used along with their percentages of the blend. We propose to base the new tile colors on the much older tile found on both the Byers and Park Hill Branch Libraries that our firm is also working on. We believe this was most likely the color blend used on the original portion of this structure. Using the Ludowici Color Guide and samples obtained from Ludowici we have determined a very close match using the following blend of colors. Again, it should be noted that this is the color blend that was approved for the new tile at the Byers Branch Library.

Ludowici Color Percent of Blend Historic Red 75% Aged Oak 15% Aged Cedar 10%

Two photos have been attached after this report. Both photos show the color blend proposed sitting on the existing clay tile roof.

Gutters

There are gutters on the east eave edge of the eastern original building’s high slope roof. At the north and south ends of the gutter, pieces return to the west about 8’. These gutters are old and were most likely placed after the original roof was constructed, as the original structure has a sloped roof with an internal gutter system. The gutters were probably placed to catch the small amount of water that runs off the main original structure’s roof just below the internal gutter. The gutters are 24 gauge painted galvanized pieces broken in a semi-half round profile. A larger 6” gutter was installed.

We propose to replace the existing painted half round gutter with new galvanized steel 6” half round gutters. We would also like to take the gutters along the north, south and west eave edges. This will help with drainage at the grade level around the building. The interior gutter will remain active. Literature showing the half round gutters has been attached along with a photo of the currently installed gutters.

If there are any questions or concerns with this report, please feel free to call.

The Contractor's written request for this inspection shall be made 72 hours in advance. With the request shall come a list of any known deficiencies and when they will be corrected. If the list is too large or contains too many significant items, in the opinion of the Project Manager, no inspection will be held because of the incompleteness of the work. 7. The Project Manager will schedule the Pre-Final Acceptance Inspection and will prepare a list of deficient items (punch list) discovered during the inspection. If during the inspection the list becomes too large or too many significant items are on the list, the inspection will be canceled. After the inspection is completed, the Deficiency List will be transmitted to the Contractor for correction of the deficient items. 8. Final Acceptance Inspection: After the Contractor has completed all items on the De- ficiency List (generated from the Pre-Final Acceptance Inspection) he shall request a Final Acceptance Inspection. The request shall be made in writing at least 72 hours in advance of the inspection. All areas must be cleaned and ready for turnover prior to this inspection. The Project Manager, the design consultant, the facility operator, a representative of the funding agency (if applicable) and other interested parties will inspect the subject Work to ensure that all deficiencies have been satisfactorily attend- ed to and that no new deficiencies have appeared and that all systems are completely functional. Any outstanding or additional deficient items will be noted and handled per the requirements of the Pre-Final Acceptance Inspection noted above until the Work is acceptable to the Project Manager.

SECTION 04 0101 REPAIR OF BRICK AND TERRA COTTA

Part 1 – GENERAL

1.1 SUMMARY OF WORK

A. For repairing brick, terra cotta and marble.

1.2 SUBMITTAL

A. Submit the following items in time to prevent delay of the work and to allow adequate time for review and resubmittals, if needed; do not order materials or start work before receiving the written approval:

1. Certificates should be submitted stating that all Installers of the repair mortar have successfully completed the training workshop for installation of the mortar.

2. Samples of all specified materials and Material Safety Data Sheets (MSDS) as appropriate.

3. Install mortar samples on masonry—preferably on the building. Do not make samples in cups or apply to plywood or other non-masonry surfaces.

4. Written verification from the Contractor that all specified items will be used. Provide purchase orders, shipping tickets, receipts, etc. to prove that the specified materials were ordered and received.

1.3 QUALITY ASSURANCE/TEST REQUIREMENTS

A. Installer certification: All repairs should be performed by a trained installer holding a Training Workshop Certificate. Contractor shall maintain proof of this credential for each installer at the site at all times.

B. Mortar Samples: Prepare a sample of each type of repair listed below, using masonry removed from the building where designated by the Owner. Prepare, install, and finish each sample repair according to the specifications. All samples must be applied to masonry. Prepare samples in an area where they will be exposed to the same conditions as will be present on the building during curing. Allow samples to cure at least three days (or longer, if possible) before obtaining Owner’s approval for color match. Mortar colors will continue to lighten as they cure and are exposed to the weather, so samples should be installed as far in advance as possible. A slightly darker color will give better long term results. Samples should be viewed from a minimum distance of 18-22 feet.

1.4 DELIVERY, STORAGE, AND HANDLING

A. Materials are to be delivered, stored, and handled to protect them from damage, extreme temperature, and moisture in accordance with Manufacturer’s written instructions.

1.5 PROTECTION/SITE CONDITIONS

A. Cold Weather Requirements: Do not work in temperatures below 40° F, when the substrate is colder than 40° F, or when the temperature is expected to fall below 40° F for 48 hours after installation of repair mortars. Building an enclosure and heating areas to maintain this temperature may only be done with the written approval of the Specifier.

B. Hot Weather Requirements: Protect repair mortar from direct sunlight and wind. Do not use or prepare mortar when ambient air temperature is above 90° F.

E. Approved alternate masonry repair products.

Part 3 – EXECUTION 3.1 WORKMANSHIP

A. Do not use any additives, such as bonding agents, accelerators, or retardants in the mortar.

3.2 PREPARATION FOR REPAIRS A. Remove all loose mortar and masonry prior to installation of the repair mortar. “Sound” masonry with a hammer to verify its integrity. If necessary, cut away an additional 1/2” of the substrate to ensure the surface to be repaired is solid and stable. Remove any sealant residue.

B. Where cramp anchors, threaded rod anchors, or dowels have been cut and pieces remain embedded in the substrate: Anchors that are free of rust, solidly embedded, and do not project beyond the surface of the masonry unit may remain. All others should be removed.

C. Cut the edges of the repair area to provide a minimum depth of 1/4”. The edges of the repair should be square cut. Do not allow any feathered edges in the repair area.

G. For very dry or porous surfaces, pre-wet the substrate ahead of time to prevent the substrate from drawing moisture out of the repair too quickly. Re-wet the surface immediately before applying the repair material.

3.3 MIXING MORTAR FOR REPAIR

A. It is recommended that a dust mask be worn during mixing. Do not mix more material than can be used within 30 minutes. Discard any mixed material that has been unused for 30

04 0101 - 2 REPAIR OF BRICK AND TERRA COTTA FIT Roof Replacement Technical Specifications

minutes or more.

B. Mixing ratios for limestone, sandstone, granite, marble, brick, terra cotta, precast concrete, and structural concrete are as follows:

1. Approximately 4 ½ to 5 parts dry material to 1 part water: M100 - Brick and Terra Cotta

C. Add water to dry ingredients and mix well. Adjust amount of water according to the weather and the porosity of the substrate.

3.4 APPLICATION OF REPAIR MATERIAL

A. Apply the mortar mix using a trowel in a series 1“ lifts allowing mortar to dry approximately 10-20 minuets between lifts. If applied in layers, scrape off any cement skin that has formed and continue application. Dampen the surface before applying the next layer. Work mortar firmly into the surface of the masonry, including the corners, and under and around all mechanical anchors. B. Build up repair material so that it is slightly above the adjacent masonry surface. Allow mortar 15 to 30 minutes to set slightly (wait time will vary with temperature and humidity–longer in cool weather), and then scrape off excess material using a straight edge (a plasterer’s miter rod is good for this). Do not press down or “float” the repair. Where repairs occur at panel edges or corners, form mortar to match the profile of the surrounding masonry. In all cases, finish and texture repair so that it is as indistinguishable as possible from the adjacent masonry.

3.5 FINISHING TECHNIQUES

A. To obtain a smooth finish to match terra cotta, marble, or brick, the finished repair can be troweled to leave a smooth surface. This may cause the repair to lighten and may need to be stained or painted to match. Glazed surfaces can be matched using Cathedral Stone’s masonry Mineral Coating and masonry Terra Coat. (see data sheet)

B. Clean any mortar residues from area surrounding the repair by sponging as many times as necessary with clean water. This should be done before repair material sets.

C. Patching mortar can be textured to match rough surfaces using a variety of finishing tools.

D. After the repair has been cured and allowed to dry for at least one week, if the appearance of a repair does not meet the specifications of the job, the surface color of the repair may be enhanced by applying a vapor permeable, mineral based pigmented stain.

3.6 CURING PROCEDURE

A. Lightly mist the repair with water to wet the entire surface of the finished repair approximately 30 minutes to 1 hour after completion on hot sunny days, and approximately 2 hours or longer, on cool or cloudy days. Time will vary with temperature and humidity. Mist several times a day during the 72 hours following the repair installation. Should access to the repairs be impossible for a period of time, plastic may be used to cover them temporarily. The application of plastic, however, does not remove the need for normal curing techniques. Never cover repairs with plastic immediately after finishing— the water in the repair will be trapped on the surface, causing it to lighten.

3.7 CLEAN UP

A. Remove uncured mortar from the perimeter of the repair before it dries using clean water and a rubber sponge. Repeat several times with clean water to prevent a halo effect (staining of

04 0101 - 2 REPAIR OF BRICK AND TERRA COTTA FIT Roof Replacement Technical Specifications

adjacent masonry). Cured mortar may only be removed chemically or mechanically.

B. Remove uncured mortar from tools and equipment with water as soon as possible. Cured material may only be removed chemically or mechanically.
