San Francisco, CA
181 Fremont Street
Scope/Solutions
At the time it was constructed, the 802 ft tower at 181 Fremont was the third tallest building in San Francisco and the tallest residential building on the west coast. The mixed-use development houses fifty-five condominiums on the upper seventeen floors, office space below, and ground-level retail. The building showcases a triangulated roof and prominent exoskeleton, giving it a profile that stands out amongst the area’s other high rises. SGH consulted on the roofing and waterproofing for the project.
SGH consulted on below-grade and terrace deck waterproofing, and roofing. Highlights of our work include:
- Helping establish performance criteria and select roofing and waterproofing systems
- Detailing and coordinating the roofing and waterproofing with other building enclosure assemblies and landscaping, mechanical, electrical, and plumbing designs
- Consulting on the below-grade waterproofing design and coordinating it with the pile foundations
- Developing waterproofing strategy for the bridge deck connecting to the adjacent transit center
- Helping design the waterproofing and integrating it with the facade assemblies at private terraces and the wrap-around observation deck
- Reviewing related submittals to compare with the design intent
- Observing in-progress and as-built construction to compare with project requirements
- Evaluating variations in the as-built details and helping develop solutions
- Witnessing field quality control water testing of waterproofing and roofing systems
