Fire Station #45

SGH investigated leakage at the building featuring aluminum glazing assemblies incorporated into two types of exterior walls: load-bearing masonry walls and wood-framed walls clad with cement plaster. We performed visual surveys to document existing conditions, water testing to identify leakage paths, and field testing to determine the water absorption of the masonry.

During our investigation, we identified leaks through the exterior walls, around windows and doors, and through the casement window assemblies. SGH developed conceptual repairs for the City of West Sacramento’s consideration and subsequently designed the following repairs:

• Recladding cement plaster walls
• Repointing masonry walls
• Removing and replacing all sealant joints associated with the exterior walls, including perimeter sealant at fenestrations, masonry expansion joints, and joints between masonry and cement plaster walls
• Replacing the windows and storefront assemblies
• Providing new louvers integrated into the exterior wall assembly
• Replacing deteriorated gaskets around the large, roll-up doors
• Overlaying the roof with a single-ply roof assembly
• Replacing the roof deck waterproofing

SGH provided construction administration services, including reviewing submittals, visiting the site to observe ongoing repair work, answering contractor questions, and helping address field conditions.
