Multi-level Residential Adaptive Use Building

Structural engineering and design services were provided for this adaptive-reuse project that transformed the outdated office building into a 510,000-sf modern apartment building. The high-rise includes 418 units with indoor and outdoor amenities. These amenities include a dramatic roof deck providing residents with 360° views of the Bay Area, garden space, grass lawn, lounges, fire pit and a grilling area.

A complete top-to-bottom renovation was completed as well as an occupancy change requiring the structure to be analyzed and proven to current building code. Our team utilized performance-based design to evaluate and analyze the existing structure. Working with the City and an independent 3rd party peer reviewer, the following four-part system to evaluate the existing structure was developed:

  • Static code level analysis
  • Static service-level earthquake analysis
  • Non-linear dynamic analysis
  • Testing of existing moment frame weld quality

The precast concrete panel exterior was replaced with a modern glass façade, and the entire interior rebuilt with high-end finishes.

The building earned a GreenPoint certification due to its adaptive reuse of the existing structure and high-performance curtain wall. The adaptive reuse project also won the Engineering News Record’s (ENR) 2015 “Best of the Best” award in the Residential/Hospitality category.
