Hoonah Cruise Ship Dock Co. hired Turnagain Marine Construction to provide a cruise ship berthing facility in Hoonah, Alaska, providing direct access to the upland amenities. Under this design-build contract, Turnagain teamed with Moffatt & Nichol, Transpac Marinas, and Jesse Engineering amongst others to provide a turn-key facility to meet the cruise ship facility demands. Design and construction include dolphins with socketed and rock anchored piling, floating pontoon, trestle and transfer span with associated supports, and electrical distribution.

The City of Unalaska hired TMC to remove and replace the existing upland and floating facilities associated with C Float with the Robert Storrs Harbor. Construction includes demolition, socketed pile, floating dock, cast-in-place concrete, site work, and both upland and dock utilities.

Services Provided: Offshore Crane & Barge Support

Working in conjunction with Global Diving & Salvage and the USCG, Turnagain utilized its crane barge, the Brightwater, to raise the World War II tugboat Challenger from the bottom of the Gastineau Channel near Juneau. Crews reconfigured the Brightwater to pass beneath the bridge to Douglas Island and move safely into position. The old tugboat weighing in excess of 150 tons was hoisted and dewatered before then being towed away for demolition.

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.

Contract Value:
$2,198,000.00

Final Value:
$2,236,467.00

Duration:
March 2017‐June 2017

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.

Customer/Project Owner:
Petro Marine, Sitka Facility

Description:
Turnagain removed the existing float facility and designed, constructed and installed an upgraded floating fuel facility. Turnagain managed the permitting process and provided constructability reviews at all stages of the design. The new float was a heavy industrial dock moored with 4 socketed 30” diameter piling. Shallow bedrock required that the float piles be driven then drilled 15’ into rock. Turnagain used a bubble curtain for noise attenuation and implemented an invasive species control plan to insure clean operations. Based on past performance and quality of work, Petro Marine is a repeat client for Turnagain.

Design‐Build

Description:
The Port Lions Ferry Terminal project sole-source, design-build which Jason Davis, Turnagain Marine Construction President, partnered with the City of Port Lions to develop a new ferry terminal facility. After two years of development and negotiation, the result was a new sheet-pile bulkhead accessed by a shot rock fill causeway faced with armor rock. Crews quarried and placed over 30,000 CY of shot rock embankment, bedding stone, and armor rock delivered via barge from an offsite quarry while enduring rough Alaskan winter weather conditions.

Notable Items:
Barging • Shoreline Grading • Bedrock Placement

Description:
Located in the extreme tides and currents of Cook Inlet, Alaska, the Chevron Nikiski Shoreline Revetment project required the installation of 25,000 CY of bedding stone and armor stone. Due to the extreme environment of Cook Inlet, armor rock was required to be quarried from over 500 miles away and barged to the jobsite. Onsite work included placement of bedding rock and armor stone in 35 feet of tide fluctuation, shoreline grading, and the demolition and excavation of the filled open-cell sheet pile bulkhead dock. Removal of the open-cell sheet pile bulkhead structure involved the handling and disposal of contaminated soils from within the excavation.
