A 19 foot wide by 82‐foot transfer span weighing 110 tons, cast‐in‐ place concrete abutment, shore side concrete approach apron, a dry fire line and an electrical distribution and lighting system. Each pile was installed using a vibratory hammer in combination with a D‐46 impact hammer. Batter pile were rock anchored into bedrock. Crews installed two 48‐inch diameter, 160 feet in length plumb pile with rock anchors and four 30‐ inch diameter, 140 feet in length batter pile. Onsite construction of the GPIP Facility presented some complex construction techniques and working conditions. Turnagain was able to provide the owner a cost savings by designing the batter sleds into the dolphin caps, reducing the amount of required falsework. Turnagain designed and constructed large pile dolphins to moor the floating dock.

To achieve a 50‐year design life with minimal maintenance the barge was retro‐fitted with a new coating system, full anode replacement, and a high capacity wear deck with the ability to handle a 260 kip axel load. Two floating dock options were analyzed with a final decision to provide the city with a 19,000 square foot retro‐fitted ABS Class barge to be the basis of the design.

Turnagain was selected as best value proposal. This design‐build project presented some unique challenges in order to provide the owner with all necessary design criteria. The Gary Paxton Industrial Park Facility (GPIP) had been long awaited by the City and Borough of Sitka. AGC Excellence in Construction Award Winning Project
