Coliseum Connections

“This project has gone very smoothly. I’m optimistic modular will be able to save money and time to create more affordable housing in the Bay Area.” 

Deanne Tipton, Project Manager of Cahill Contractors

“The goal with modular construction is when it’s done, no one will know it’s modular.”

Stacking Up to Affordability: Oakland’s largest modular residential project

Coliseum Connections will be Oakland’s largest modular residential development adjacent to a BART station. All 110 residential units in the four-building development were designed utilizing wood-framed modular construction to shorten the construction schedule and minimize overall construction costs (an estimated $4 million was saved in construction costs). The project was completed within 17 months. 179 modular units were stacked together to construct the development. 

In addition to utilizing factory-built housing, this structure also required the use of three material types to support the factory-built portions: wood stem walls at the crawl space, steel framed transfer beams for a large amenity space, and a large elevated concrete slab over underground parking. DCI Engineers’ coordination of interface details for the three supporting materials required close coordination between the design team, the general contractor, and the modular supplier.

DCI designed the primary framing systems, which included the PT concrete podium deck that integrated detailed connections for the installation of the modular units. 

Project Highlights

  • Contains 110 living units (half market rate rental units and half affordable rental units).
  • The five-story main building contains a community café and gym.
  • Three buildings include 44 two-story townhomes.
  • DCI designed the foundation system considering the required extent of soil improvements to control differential settlements between the change in foundation elevations of the main building and the parking garage.
  • A partially below-grade parking structure with 89 stalls.
  • Development is located next to the Coliseum BART Station.
