- Permitting coordinationLocal, state, federal, environmental, and consultant requirements stay connected to constructability.
- Specialized equipmentBarges, cranes, landing craft, tugs, service boats, and fabrication support demanding sites.
- Long-term serviceInspection, maintenance, lifts, accessories, repair, and upgrades protect the finished work.

A working waterfront legacy
Built on the water since 1976.
This photograph captures Paul Wilcox, founder of Waterfront Construction, aboard an early WCI workboat—a reminder that this company was built by people doing the work on Northwest waters.
The equipment and projects have grown, but the standard remains the same: understand the site, solve the hard problems, and build work that lasts.
