Fast track infrastructure project to secure a Tier 1 Transmission Substation. Project required installation of precast concrete walls, double stacked wall ranging in size from 12’ to 16’ tall. The project presented many challenges including varying soils conditions, inclement weather and multiple agencies (County of Santa Clara, NERC and Cal Trans). Soils conditions varied greatly throughout the site ranging silty sand, cobbles/boulders and serpentine. Installation the foundations required several different drilling methods. Several agencies had to be coordinated for permitting, engineering and testing/inspection throughout the project, including Cal Trans for work within the HWY 101 Right Of Way.
No injuries or near misses on the project.
7,400LF of precast concrete security wall ranging in size from 12' to 14' tall
