Ballard provided personnel composed of a four-person surface supplied diving crew to team with the owner’s engineer to provide a full structural inspection and analysis of the Alcoa Pier pilings and pierhead.
Scope of Work
Multi-season repair work which consisted of the following types of repairs: timber pierhead, epoxy jacket, concrete, and piling. These repairs were recommended by the experienced dive crew Ballard mobilized on-site.
Ballard handled both the inspection portion as well as the numerous repairs deemed necessary by the inspection crew. The repairs were handled throughout the years, after project execution, to avoid the harsher seasonal weather months. Working underneath the pier, both above and below the water’s surface, required numerous workarounds to protect Ballard crews, as well as efficiently execute the inspection and necessary repairs. Safety protocols and a United States Coast Guard’s (USCG) approved dive platform was utilized to overcome the tight regions underneath the pier.
These necessary repairs ensured the structural integrity of the pier for years to come and brought ease of mind to the owners. In addition, with an after-repair inspection, the owners have an established baseline to determine if future repairs are needed.
