Project Description:

At the top of San Francisco’s Russian Hill we replaced a failing 35’-tall retaining wall with a new shotcrete and rock-bolt wall. The new wall was colored and sculpted to harmonize with the nearby rock slopes. 

A job-specific man-basket was fabricated to allow the drilling and installation of rock anchors 30 feet above the roadway. The work was within the city right-of-way and in front of the entrance to a large parking garage, requiring close coordination with The City of San Francisco and the residents of the Summit Condominiums.
