1395 22nd Street Construction Progress UpdateSep 04 2018 · 0 comments · Mixed-Use, NISHKIAN MENNINGER, Residential ·0
Construction of the 980,000 GSF, mixed-use residential and public stair project in Potrero Hill and Dogpatch neighborhoods has been an unusual spectacle for most San Franciscans. Align Real Estate, Perry Architects, Min|Day, Fletcher Studio, Build Group, and Nishkian Menninger are teaming up on this challenging project to put a 600-foot long building onto the east side of Potrero Hill.
When completed 1395 22nd Street development will include two structures: an eight-story residential building over a below grade parking garage adjacent to a three-story industrial building. The northern residential building will contain 263 residential units, landscaped open space, and the industrial space will be used for Production Distribution and Repair (PDR) by the City of San Francisco. 1395 22nd Street structure is being built against an 80-foot tall serpentine hill, cut at a 1:1 slope. It required 260 micropiles, 126 tiebacks, 240 soil nails, 68 rock bolts and 3,000 lineal feet of grade beams cut into five levels of hillside to anchor the structure to the hill. The vertical load-carrying system for these buildings will consist of post-tensioned concrete slabs supported by reinforced concrete columns and concrete shear walls. The façade will use various building materials to appear as individual residential buildings along the hill. The two buildings are supported by deep foundations and are separated by a seismic joint.
A serpentine stair at the north side of the construction site will connect Missouri Street at the top of Potrero Hill to Texas Street at the bottom. The stair covers an elevation gain of approximately 85 feet and allows access to the residential building on multiple landings.
With the completion of the hillside anchorage, the project is on schedule to top out the structure this month, September 2018. We are also pleased to report that the project is on track for LEED Gold Certification, and project completion is on target for the Summer/Fall of 2019.
