Spring Valley, CA – A roadway improvement project to increase pedestrian safety. Cast in place retaining walls were constructed at existing side slopes to widen the street for sidewalk and curb ramp construction. In addition to the 2700 square foot cast in place retaining wall a 4250 square foot soil nail and shotcrete retaining wall was constructed in order to cut back a slope on the opposite side of the street.
This was a landslide repair to a slope that undermined four houses and a swimming pool in Oceanside, CA. The site work included the installation of tie backs (56 anchors with 300 kip loads) and reinforced shotcrete (225 Cubic yards). The project also included slope re-grading (14,000 cubic yards), and the reconstruction of an existing retaining wall.
Groundforce can be seen here putting up the sculpted Shotcrete finish for a 600 foot long, 10,000 square foot Soil Nail Wall project for the folks at KB Home in San Marcos.
This is the first time we have worked with KB Home and we hope to do more in the future.
Groundforce has completed construction of a Seawall for the City of San Diego in La Jolla. The Seawall was constructed to prevent bluff erosion and undermining of the new City Lifeguard Station being constructed at the site.
The project required use of limited access drilling equipment. The wall was constructed with a series of tie back anchors and sculpted Shotcrete to simulate the surrounding bluff materials. The project General Contractor was Stronghold Engineering. Geotechnical Engineering was provided by Southern California Soils and Testing. Structural Engineer of Record was BWE/Burkett and Wong.
Working under contract with the City of Alhambra, Groundforce has just completed the Grandview Drive Wall Stabilization Project. The work included installation of 125 Soil Nails, 180 Cubic Yards of Reinforced Shotcrete, Wrought Iron Fencing and a Plaster finish at the shotcrete wall.
The project Geotechnical Engineer was David Colbaugh with Evans, Colbaugh and Associates. Soil Nail wall design was by Ricardo Jordan with Earth Support Systems, Inc.
