ANCHORAGE, AK – PND Engineers, Inc. (PND) recently earned eight awards for four Alaska projects. Recognition came from the States Organization for Boating Access (SOBA), Engineering News Record (ENR), the Society of American Military Engineers, and Pile Driver Contractor Association (PDCA). The Port of Juneau Cruise Ship Berths project was the most decorated, collecting five honors.

The Statter Harbor Boat Launch Replacement project received an Outstanding Project award from SOBA in August. The City and Bureau of Juneau entered into a cooperative agreement with the Alaska Department of Fish and Game (ADFG), Division of Sport Fish (Sport Fish) to fund the replacement of the existing Statter Harbor boat launch. The original boat launch ramp and boarding float was constructed in 1986 by the State. The use of the existing facility was limited during low tides because the concrete ramp surface did not extend to sufficient water depth and parking capacity was inadequate to meet demand. The low tide limitations caused further congestion and backups in the parking area during the low tidal stages. The deteriorated ramp was recently replaced with a new two-lane, all tide boat launch ramp including a new ADA compliant boarding float. The new ramp has increased the boat launch capacity and in combination with the new parking area has decreased wait times and congestion and improves safety. Improvements also include reconfigured highway access, uplands parking expansion for 100 vehicles with trailers, 85 vehicle only stalls, make ready and tie down lanes and improved launch maneuver and traffic flow patterns. Earlier this year, the Statter Harbor Boat Launch project was recognized as the 2016 ASCE Juneau Project of the Year.

PND designed winning entries in multiple categories in the 2017 ENR Northwest Best Projects competition. Winners of the competition – which was open to projects in Alaska, Oregon, and Washington – were announced in late September. PND’s winning projects were the Port of Juneau Cruise Ship Berths, which took top honors in both the Best Airport/Transit and Best Specialty Contracting divisions; and the Chignik Public Dock, named Best Highway/Bridge project. The dock qualified in that category because it serves as a regional stop for the Alaska Marine Highway System (AMHS).

The Port of Juneau Cruise Ship Berths subsequently won two additional 2017 Best Projects Awards from ENR in the Excellence in Safety and Specialty Construction categories.

Manson Construction Co. was the general contractor for the City and Borough of Juneau’s port project, which was completed in May. Pacific Pile & Marine, LP, built the Chignik dock for the Alaska Department of Transportation & Public Facilities, also completed in May. Both projects are now eligible to compete for ENR’s national Best of the Best award, which will be announced in December.

The Port of Juneau project designed two new cruise ship berths directly offshore from an existing timber wharf, to accommodate cruise ships up to 1,100 feet long with varying widths and offloading configurations. The design utilizes two floating concrete floating pontoons, a 50-foot by 400-foot south berth and a 50-foot by 300-foot north berth, two HS-20 load-rated vehicle transfer bridges, mooring and breasting dolphins, pile supported approach docks, small vessel moorage float, gangways, catwalks, various dockside water, sewer, and electrical utilities, and other necessary infrastructure in support of tourist activities. Extensive large diameter steel piles were incorporated into the design to support compression, tension, and lateral loads in variable soil and bedrock conditions. PND utilized rock sockets, rock anchors, and SPIN FIN™ pile tips in the design based on specialized experience developing marine foundation solutions.  

For Chignik, PND designed a new multi-use public facility to meet both transportation and commerce needs of local and regional communities. The dock serves as an all-tide deep-draft facility that can accommodate medium- and large-vessel berthing and provide moorage of Alaska Marine Highway System vessels including the Tustumena, Tustumena II and Kennicott. The modern, high-capacity sheet pile bulkhead is 310 feet long., and project documents were prepared to meet requirements for FHWA/DOT grant funding.

The Juneau Cruise Ship Berths project was also named 2017 PDCA Project of the Year in the Associate/Engineering Affiliate category. This award, announced in September, highlighted the project’s use of a pile-supported solution to address access, mooring and breasting structures over deep water. PND’s design used 179 steel pipe piles, incorporated into 24 independent structures, to support the two berths. The piles ranged from 24 feet to 48 inches wide, and from 100 feet to 240 feet long. Where overburden was insufficient, PND incorporated tensioned rock anchors through the center of the driven piles. Where full-moment connection was required in shallow overburden, PND used rock-socketed pipe piles with rock anchors to support the deeper water structures.

Most recently, PND earned kudos for its design of the U.S. Coast Guard Forward Operating Location Hangar at Cold Bay. The design-build project by AKS Architecture & Tutor-Perini Construction earned the SAME Seattle-Tacoma Post’s 2017 Small Business-Gold Award in its Projects of Excellence competition, announced in early October. Along with a new 70-foot by 90-foot hangar, the project, completed in October, included site demolition, site work, concrete apron, sidewalks, fuel tank, fencing, and water and sewer connections. PND provided geotechnical, civil, structural, and foundation design, and obtained permits, and provided construction administration support. Geotechnical field investigations utilized a dynamic cone penetrometer (DCP) test to determine in-situ strength and stiffness properties as a cost savings technique for the foundation design. The foundation will include conventional reinforced concrete spread footings at frame columns, and a thickened edge at the slab perimeter. The main structure will be a four-bay pre-engineered metal moment frame building with a mezzanine and breezeway tying in to the adjacent, existing hangar. A snow drift study was conducted using wind data collected at the Cold Bay airport. The hangar was designed for both high wind and high seismic loads anticipated at the site, with a metal roof, snow guards and bird protection.

PND, founded in Anchorage in 1979, is a full-service engineering firm that provides civil, structural, arctic, marine, geotechnical, and coastal engineering; hydrology; surveying; environmental permitting; project management; and construction inspection services for a range of projects. PND has offices in Anchorage, Palmer and Juneau, Alaska, Seattle, Wash., and Houston, Texas, as well as a subsidiary, PND Engineers Canada, Inc., in Vancouver, B.C.


 

CHIGNIK DOCK PROJECT KUDOS

Chignik Dock Team,

You all deserve a big kudos for a job well done.  The Alaska Marine Highway System (AMHS) ferry M/V Tustumena just recently made its first docking at the new Chignik facility… Please enjoy the attached photos of this event. The preceding emails show that the community, AMHS, and DOT Commissioner are very happy with the new dock facility in Chignik.  I’ve heard nothing but compliments about the project you all participated in to make happen.  Most dock users will probably never know how challenging this project was and the amount of effort and collaboration each of you gave to the success of the project.  If I haven’t said this to you before, working with each of you during the construction of the project was a great pleasure.  As a DOT construction manager, this project has been my favorite project to work on so far simply because of your team spirit and hard work …  So thank you for making this project such a success!  

Thanks,

Todd Boris
