Kaiser Roseville Medical Office Building 2

The Kaiser Roseville Medical Office Building 2 project is a 4-story, 265,000 square foot facility on the Kaiser Roseville Campus. Originally designed as a Special Concentric Braced Frame (SCBF) structure, the design was revised to Buckling Restrained Braced Frames (BRBF) during Design Development. Buehler utilized an alternate means of compliance and performance-based analysis to including nonlinear static pushover analysis to justify the use of the BRBF system as it was not yet a recognized system per the California Building Code. This change resulted in a savings of approximately $750,000.00 in structural steel and foundations while reducing the construction duration by 3 weeks.

Size: 265,000 SF
Architect: Stantec
MOB 2 was the first BRBF structure in Placer County; the analysis included a nonlinear static pushover which reduced column demands at the BRBs

Construction Cost: $54,000,000
Contractor: Rudolph and Sletten
Foundations consisted of spread footings on 2’-3’ CLSM fill bearing on high capacity soil – unfortunately, despite numerous borings, there was a previously undetected vein where the high capacity strata was ~12’ below the surface; coincidentally the largest footing on the project requiring almost 70 yards of CLSM in one excavation
