1. Structural Repairs to Roof Decking The existing blocking between the roof truss was not connected to the roof truss, allowing the sheeting to move, which loosened the plywood nails. The structural engineer recommended repairing blocking at key areas and stapling the existing plywood to replace the loose nails. 2. Additional Stucco Removal and Installation The limits of stucco replacement were expanded on the upper south side of the building (facing Bernal Avenue) due to failed waterproofing behind the existing stucco. Additional stucco was removed to install new flashing between the roof and the walls after the existing flashing that was to be reutilized was found to be in worse condition than originally thought. 3. Address Concentrated Roof Water The roof has large valleys that drain through a single point. After removing the roof at these locations, extensive water damage was encountered. To prevent future failures, additional downspouts and metal flashing were added, armoring the areas against premature failures. 4. Window System Change for Seismic Bracing The specified window system had a wider frame that conflicted with the seismic bracing of the building. The window system was changed to a system with a thinner frame that could accommodate the seismic braces. 5. Plywood Replacement at Eaves The plywood at the eaves was found to have early stages of dry rot and the structural engineer recommended that it be removed and replaced. The work includes coating the underside of the eaves to prevent future deterioration of the wood. 6. Miscellaneous Wood Repairs Water-damaged wood was repaired in various areas throughout the roof. It included repairs to the fascia boards, roof decking, blocking and valley areas. An additional $294,938 of potential change orders has been identified to replace the gable end windows, relocate the HVAC equipment to install maintenance access ladders, and cover the costs to address project delays. The work is as follows: 7. Gable End Windows As mentioned above, the existing windows were found to be primarily held in place by stucco and not connected to the framing as required. In addition, the windows did not have waterproofing around their openings and showed signs of water instruction at many locations. The clerestory windows are included in the contract, but the gable end windows were not included. To correct the issue, the gable end windows need to be pulled out, have window framing added, then flashed and reinstalled. The architect recommended the installation of new windows instead of the reuse of the existing windows to improve energy Page 3of5
