TRANSMISSION MAIN, Anchorage, AK

Client: Anchorage Water & Wastewater Utility
General Contractor: MWH Americas, Inc.

Project Summary:
B.C. Excavating assisted MWH Americas, Inc. field crews using SmartBall® technology to record and detail the condition of approximately 130,000 lf of large diameter water mains. The SmartBall®, produced by Pure Technologies, is a free-floating foam ball with an instrumented aluminum core that detects acoustic activity associated with leaks and pockets of trapped gas in pressurized pipelines. In other words, the ball “listens” for leaks as it floats through a pipe. The acoustic signal also helps to identify pipe segments that have been weakened by corrosion, so that AWWU can plan for maintenance before an emergency repair is required. B.C. Excavating was tasked with project support ranging from setting trench boxes and caissons to preparing pipe for testing sensors on transmission main ranging from 24 inch to 72 inch in diameter throughout Anchorage.

MOUNTAIN VIEW VILLAGE LOFTS, Anchorage, AK

Client: Cook Inlet Housing Authority
General Contractor: Boslough Construction, Inc.

Project Summary:
B.C. Excavating teamed with Boslough Construction to build a mixed use residential/commercial building for Cook Inlet Housing Authority. For the utility installation B.C. Excavating utilized two of its Vactor trucks along with its caisson and specialty trench shoring technology to surgically locate and connect to a water mainline running down a main street in Anchorage. The work was required to be performed over the weekend and at night so that a full shut down of the four-lane street could be accomplished. The site itself proved to be a challenge in its own right. As site excavation proceeded, it became immediately apparent that the site had in the past been utilized as an asphalt disposal pit with areas of densely compacted asphalt ranging from 5-20+ feet thick. B.C. Excavating set up an onsite screening plant, screened the asphalt and disposed of it off site. The large volume of asphalt exported from the site left the client facing a huge potential cost in replacement structural gravel. Through value engineering, B.C. Excavating and the clients came up with a plan to mine an area of the site that did not require structural gravel to help off-set the costs. The project also required the reconstruction and updating of Park Street which included new traffic loops, sidewalks, retaining walls and signage.

LITTLE CAMPBELL CREEK FISH PASSAGE IMPROVEMENTS, Anchorage, AK

Client: Municipality of Anchorage, Public Works

Project Summary:

Once the concrete box culvert was put into place a channel substrate was placed in the bottom of the culvert and a meandering channel was constructed for the fish. Headwalls were constructed on either end of the fish passage and final restoration included paving the site and providing stream embankment stabilization measures.
