Cerrudo Services repaired two existing floating docks and gangways at the US Coast Guard Station Humboldt Bay. The work included removing, disposing and replacing existing pile guide assemblies, gangway casters, gangway connections and boat dock bumper wheels.
The pile guide assemblies were designed to be fabricated and galvanized prior to installation. The guide piles were surveyed before fabrication to determine pile batter and location so that the pile guide assembly would not bind at any time during tidal variations. After fabrication, the pile guides were installed to ensure a one inch gap between the pile and roller when the pile is centered to the pile guide assembly.
The gangway connections were replaced with one inch stainless steel pivot rods rotating on new fabricated pier mounts. Each gangway was fitted with new heavy duty swivel casters to allow lateral movement during extreme weather conditions. Floating dock bumper wheels were removed and replaced with 9-1/2 x 8 inch rubber corner bumpers on all corners of the floating dock.
The project was scheduled to minimize interference with the Coast Guard facilities normal operations. The two floating docks remained in service during the entire construction period.
