Project Overview
Collins, as a subconsultant, performed an underwater inspection of a remote island community’s dock in Hydaburg, Alaska.
The dock is composed of varying sections of timber decking and caps with timber piles, as well as concrete decking, steel/concrete caps, and concrete piles. A Level I and Level II underwater inspection was performed by Collins’ in-house engineer-divers using surface-supplied air equipment. Water depths at high tide are up to 50 fsw. A hydrographic survey was also performed.
