Tetra Tech INCA provided preliminary and final design for the Sitka Dock. INCA developed alternatives for the shore connections and mooring system; analyzed loads, tidal fluctuations, and wind loads; evaluated and developed alternatives for pontoon reinforcement; and provided siting of the pontoon. Special features included the design of ramp connections using a specially fabricated set of elastomeric and steel bearings for kinetic energy absorption in the event of docking collisions.

This design was named an “Outstanding Example of Excellence in Concrete Construction” by the Washington Aggregates and Concrete Association.
