Customer/Project Owner:
City and Borough of Sitka
Contract Value:
$6,800,000.00
Final Value:
$6,915,934.00
Duration:
September 2017‐December 2017
Description:
The Gary Paxton Industrial Park Facility (GPIP) had been long awaited by the City and Borough of Sitka. This design‐build project presented some unique challenges in order to provide the owner with all necessary design criteria. Turnagain was selected as best value proposal. 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.
The barge was dry‐docked and inspected. 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. Turnagain designed and constructed large pile dolphins to moor the floating dock. 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.
Onsite construction of the GPIP Facility presented some complex construction techniques and working conditions. 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. Batter pile were rock anchored into bedrock. Each pile was installed using a vibratory hammer in combination with a D‐46 impact hammer. 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.
Project was completed in the highly sensitive environment with strict environmental oversight. The design‐build approach allowed the owner to have great cost certainty and through completion only saw owner initiated, additional scope, change orders.

Description:
Turnagain Marine Construction was awarded a design-build contract to construct a heavy duty freight dock. The project owner, Kloosterboer Dutch Harbor, was looking for proposals to extend their existing facility’s berthing line to the southwest. Turnagain Marine Construction proposed a complete turnkey design that not only met but exceeded Kloosterboer’s criteria. The dock would be constructed to allow for 750psf uniform loading while providing a 50 year service life.
At the base of the dock there is galvanized steel pile that are capped with precast prestressed concrete panels. The fender system is comprised of HDPE sleeved steel pile along with a rubber energy absorber fender system. A heavy duty galvanized steel bull rail runs along the edge of the dock with 13 mooring bollards. The dock extension has mooring and berthing capabilities along the East and the West edge of the dock, as well as a diagonal berth on the south face of the dock. This system is well suited for commercial vessel operations and will allow Kloosterboer to grow its ever expanding business in Dutch Harbor, AK.

Description:
When the City of Kodiak decided
to replace their vintage Channel
Transient Float they wanted the
most economical project available.
With the best technical response
and the lowest price Turnagain
Marine Construction (Turnagain)
was selected as the best value
design‐build proposal. Turnagain
proposed a complete turnkey
design that not only met, but
exceeded the City of Kodiak’s
design criteria while providing a
total construction duration within
the City’s time constraints.
For the extreme durability that was required at this particular site location, 36” diameter HDPE pipe was chosen for the floatation medium. The float structure consists of heavy creosote glulam timbers, ADA compliant steel grate decking, and an 8” galvanized bullrail. The fender system consisted of 1‐1/2” thick by 20” deep UHMW‐PE, these pile pockets were internal to the float system and were lined using the same UHMW‐PE. Highly durable 24” x .750” steel piling was utilized to secure the float system.
The piling were driven through the existing overburden layer and then socketed into the bedrock to attain the designed loads. A shore side concrete abutment and aluminum gangway was utilized to access the floats. The gangway and float system were outfitted with an electrical system, potable water and a dry fire line system.
Project was completed on‐time and with only owner initiated additional scope change orders.
