Visa Metro Center

OVERVIEW
Langan provided geotechnical services for the design and construction of VISA's West Coast headquarters in Foster City. The project consisted of two 12-story office towers and adjacent 4-story parking structures. Foundations for the buildings include 125-foot-long, 14-inch-square, reinforced concrete piles designed for allowable loads of 130 tons. The piles extend through 50 to 60 feet of man-made fill and weak marine deposits, taking support in stiff clay and dense sand at depth.
