The French Market
SGH provided fire life safety and accessibility consulting services to assess the original French Market building and identify conditions that may need to be addressed as part of the planned renovation project.

Scope/Solutions
The new nineteen-story building at 200 Park Avenue brings 965,000 sq ft of Class A office space and 22,400 sq ft of outdoor terraces to downtown San Jose. The structure relies on a lateral-force-resisting-system comprising composite plate shear walls known as SpeedCore, making it the second project of its kind in the world and first in California to use this system. SGH provided construction engineering services to the steel fabricator/erector.
By performing advanced analyses, SGH helped the construction team progress ahead of the already efficient schedule afforded by the SpeedCore system. Highlights of our work include:
- Evaluating the partially constructed building behavior under lateral loading
- Designing shoring and bracing, including a temporary lateral-load-resisting system to stabilize the structure during erection, and providing the structural steel erector with bracing options to facilitate erection of eight levels of steel above the highest completed floor system without grouting the SpeedCore steel plates
- Performing finite element analyses to understand the behavior and buckling strength of the ungrouted steel plate system; evaluating the structure’s ability to support two tower cranes attached to the bare steel plates ahead of grout placement several levels below the cranes (a condition not represented in the contract documents); and recommending additional trusses constructed within the core of the steel plates to achieve the required strength and stiffness—allowing the general contractor to achieve the aggressive construction schedule
- Providing analysis and erection requirements to maintain lateral stability of steeply sloping columns
- Designing weld platforms, including temporary connection details
- Evaluating column lifting lugs and base for temporary construction loading
- Assisting with the erection aid design

SGH designed a seismic upgrade for the building in 1982. In the late 1990s, SGH conducted a prepurchase survey of the exterior facade and was then retained by the new building owner to design facade repairs.
