San Francisco, CA
340 Fremont Street
Scope/Solutions
The 41-story apartment tower at 340 Fremont Street offers luxury residences and many amenities, including lounges, a fitness center, below-grade parking, a dog park, and podium terraces designed for entertaining. The building, clad primarily with curtain wall, metal panels, and precast concrete, fits well amongst the surrounding modern high rises in the budding Rincon Hill neighborhood. SGH consulted on the building enclosure design.
SGH consulted on the design for below-grade, podium, planter, and balcony waterproofing; precast concrete and metal panel rain screen exterior wall systems; glazing; and roofing. Highlights of our work include the following:
- Helped select building enclosure systems to meet budget and performance requirements
- Reviewed proposed design concepts and performed preliminary analysis to verify glass types and mullion design
- Modeled intersections of roofing, waterproofing, and cladding to evaluate constructability and continuity of the building enclosure
- Developed details to integrate the various systems
- Prepared specifications for roofing, waterproofing, and flashing, and performance specifications for the design-assist cladding
- Assisted with reviewing bids and answering contractors’ questions during the bidding process
- Visited cladding manufacturing plants to observe quality control procedures
- Participated in cladding coordination meetings with the subcontractors, general contractor, and architect during shop drawing development to resolve detailing and installation conflicts prior to construction
- Observed cladding mockups and performance testing
- Provided construction administration services, including reviewing contractor submittals, observing ongoing construction, and witnessing field testing to compare with the design and performance requirements; performing special warranty inspections for below-grade waterproofing; and analyzing alternate details to accommodate as-built variations
