Excavating began the project with less than 60 days left in the construction season for paving, work on the project consisted of installing water, sewer and storm improvements. Prepping for building slab and prep for curbs sidewalks and paving. Work was accomplished on time and on budget with snow falling one day after paving. For the B Street location, a 32,000+ square foot building, oversized footings were required due to the height of the building and utility connections and a storm water system were installed.



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:
In May of 2011 B.C. Excavating was awarded a contract to install a 340-foot concrete fish passage in Little Campbell Creek. During construction the creek was diverted through a 24-inch HDPE pipe. 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.

Project Summary:
B.C. Excavating was the general contractor for the installation of a landfill gas collection system to burn Methane from the Anchorage Regional Landfill. B.C. Excavating was able to complete the project on time under very tight time constraints. During the course of the project B.C. Excavating provided the client over $65,000.00 in savings through value engineering proposals. The project included installation of 14,000 lf of 4-18 inch HDPE piping around the landfill to transport landfill gas. The piping was tied into 50 vertical wells that were drilled onsite. Our subcontractor, Criterion General, constructed a 30-foot by 50-foot building to house the equipment to process the gas. Enterprise Engineering designed the foundation for B.C. Excavating on this project. A 45-foot flare was set up onsite for burning the landfill gas. In addition to the gas extraction system B.C. Excavating installed over 5,000-feet of perimeter trenching around the landfill to control stormwater runoff.

Excavating utilized seven trench boxes and four caissons to ensure the safety of all personnel involved. This project involved intricate traffic control, heavy public involvement and concerned business owners. Daily public involvement was necessary to keep the business owners informed of road closures and disruption to their services. A close and cooperative working relationship was essential to the successful completion of this project.
