Representative highlights of Willdan Geotechnical's recent bridge projects are presented below.
Client: U.S. Army Corps of Engineers
Project: Los Angeles River Bridge Repair & Replacement
Willdan Geotechnical provided an engineering geology and geotechnical engineering study for the replacement of a 755-foot long railroad bridge over the Los Angeles River and a 282-foot bridge over the Dominguez Channel. The geotechnical investigation included the development of drilling work plans, drilling safety plans, construction of temporary diversion dikes in the river channel, soil logging, soil sampling, borehole abandonment, evaluation of nearby active faults, borehole geotechnical and geophysical testing, probabilistic seismic hazard analyses, quantitative liquefaction and settlement estimates, detailed pile design recommendations, borehole geophysical test report and foundation report.
Client: City of Agoura Hills, California
Project: Kanan Road/101 Interchange Design
This project won the Southern California APWA Traffic Congestion Mitigation Project of the Year in 2007. Willdan Geotechnical performed geotechnical investigation that included development of drilling work plans, permit acquisition, traffic control, soil and rock logging, sampling, laboratory geotechnical tests, and foundation recommendations for highway improvements consisting of removal of existing off-ramps, relocation and widening of streets, construction of bridges and relocation and construction of new on- and off-ramps.
