Location: Santa Clara, CA

Project Partner: Truebeck Construction

Challenge: Design and execution of temporary construction dewatering of a jobsite without affecting external water levels.

Overview: Condon-Johnson was contracted to design and build an impermeable shoring system and dewatering system and install foundation driven piles for a new six story office building with two levels of below grade parking and mechanical rooms.

Results: Condon-Johnson analyzed the site’s subsurface conditions composed of stream deposited alluvium consisting of interbedded layers of clay, silt, sand, and gravel. This soil profile coupled with the building’s unique footprint made for a complex permeation cutoff and dewatering model. Condon-Johnson’s design and execution produced a dewatered construction site without affecting the ground water level outside of the property.
