1031 Walnut, currently in design, is a large multifamily development consisting of two separate four-story Type V wrap buildings with approximately 670 dwelling units in Fremont, CA. The project’s unique shape and configuration includes several landscaped courtyards with a swimming pool, creating smaller communities within the large development.
Each building will have an above-grade concrete parking garage, totaling nearly 1,200 stalls. The parking garages are surrounded by units. North Garage is six-level, and South Garage is five levels with roof deck amenities on the sixth level, including a pool, bowling alley and fitness room.
The long spans needed in the amenity spaces were accommodated by utilizing a concrete post-tension slab which was integrated into the light frame structure. This maximized flexibility of the space by minimizing internal columns.
CKC worked closely with the geotechnical engineer to solve the site’s soil issues and ultimately used a shallow foundation system below the parking structure and a post-tension foundation below the residential structure. The two structures have significantly different weights and so it was necessary to balance these foundation systems to minimize differential settlement.
