Transportation

BSK supports transportation agencies and project teams with environmental, geotechnical engineering, materials testing, and special inspection services for infrastructure projects throughout California. Our experience spans planning, design, construction, and redevelopment of transportation facilities, where regulatory compliance, public safety, and constructability are critical to project success.

From early environmental investigations to construction-phase quality assurance, BSK provides technical support tailored to the complex conditions often associated with transportation corridors and facilities. Our environmental professionals perform site assessments, soil and groundwater investigations, and hazardous materials characterization at rail yards, airports, shipyards, roadways, and other transportation hubs—addressing impacts related to fuels, lubricants, solvents, and legacy industrial uses. During construction and redevelopment, we deliver timely analytical and waste characterization services that help manage risk, support disposal decisions, and maintain compliance.

BSK’s geotechnical engineers and construction services teams work closely with public agencies, engineers, and contractors to support local, regional, state, and federally funded transportation projects. We understand the regulatory, safety, and quality requirements associated with transportation infrastructure and perform services in accordance with Caltrans, ASTM, AASHTO, and applicable federal standards. Our certified laboratories and experienced field staff allow us to respond quickly and scale resources to meet demanding schedules.
