Bridges
West Coast Contractors constructs durable bridges that connect communities, utilizing expertise in foundations and pile driving. Our team adapts to environmentally sensitive areas while maintaining structural integrity in harsh conditions. Recent projects include replacement bridges in Crescent City, California, featuring concrete piers and decks built on challenging terrain.
Marine Construction
We specialize in marine construction projects like piers, harbors, and cofferdams, overcoming challenges such as weather and environmental restrictions. Our work on NOAA's Marine Operations Center in Newport, Oregon, demonstrates our ability to meet tight deadlines while minimizing ecological impact through GPS-guided technology.
Pile Driving
Our precision pile-driving services support infrastructure like power plants and bridges. For Pacific Gas & Electric's Humboldt Bay Power Plant, we drove nearly 1,000 concrete piles with specialized hammer attachments, ensuring structural stability in confined spaces near overhead power lines.
Shoreline Rehabilitation
We restore shorelines while balancing ecological concerns and structural needs. Projects involve dredging, erosion control, and habitat preservation, as seen in our work on the Isthmus Slough Bridge, where we installed cofferdams to enable underwater construction of bridge piers.
Foundations
Building strong foundations requires geological expertise and environmental sensitivity. For Oregon Resources Corporation's mineral processing plant, we removed contaminated soil, drove over 500 pilings, and poured 8,000 yards of concrete to create a stable base in sandy soil conditions.
