Superblock

San Bernardino, California
The City of San Bernardino developed this major
downtown commercial project with various State of California departments as the prime
tenants.
The 13-story signature building is intended for CalTrans district offices, and includes
some retail components at the base. Another 6-story office building is designed to
consolidate various other state offices and also includes some retail spaces. Tthe project
also includes a six level parking facility for about 1,600 cars, transportation
facilities and an auditorium for the common use of the offices in both buildings.
The office buildings are framed in structural steel to provide column free space for the
offices and minimize loads on the driven pile foundations. The earthquake and wind loads
are resisted by a combination of special moment frames and eccentrically braced frames.
The parking facility is a cast-in-place post-tensioned reinforced concrete structure
utilizing long span beams and one-way slabs with shear walls for resistance to earthquake
loadings.
