PROJECTS > RETAIL / MIXED-USE / SEISMIC STRENGHTHENING / Macy's Union Square

Project Description /Overview

NYA provided structural and earthquake engineering and design services for the Union Square City Block renovation and expansion. This mixed-use project included a new seven-story concrete framed Macy's Union Square structure designed as a new spine to interconnect and provide seismic strengthening for all four adjacent Macy's buildings, including historic structures built prior to the 1906 San Francisco earthquake. Renovation of the Macy's Union Square Flagship store was on a three-year, multi-phased schedule. The entire store was refurbished and seismically upgraded.

 

Phase I consisted of seismic upgrade and interior renovation of Macy's North into five levels of retail and three levels of office space. Phase II was the tear down and construction of 225,000 square feet of new poured-in-place concrete with a glass and granite fasade (the grand entry is centered on Union Square). Phase III was the continual process of seismic strengthening and retail interior construction to the balance of the buildings based on a series of retail moves.

 

The entire 31-month renovation was performed while the building remained open. The project serves as an excellent example of NYA's continuity in large-scale multi-phased projects.
