Briarwood Sewer 
Billings, Montana

 

In 2008, COP Construction LLC was awarded the $5.2 million project for sanitary sewer improvements to the Briarwood Subdivision in Billings, Montana. This subdivision is located 5 miles south of Billings on the south side of the Yellowstone River. The scope of the work included 24,000 lineal feet of 8 inch through 18 inch sanitary sewer pipe, 850 lineal feet of suspended pipe for the crossing of the Yellowstone River from the existing highway bridge, construction of a lift station wet well, building, and related pumps and mechanical piping, installation of six bore and jack casings, and a 70 foot service bridge. The project route passed through rural property and the Briarwood Golf Course. The south end of the work ended at the small treatment plant serving the Briarwood Subdivision. The existing treatment plant was no longer needed and was removed upon completion of the project. Several areas of the sewer pipe installation required excavation depths as great as 30 feet. The bore and jack work was performed by three separate subcontractors, coupled with our support for shoring, pit construction, and ultimately assistance with grade adjustment in order to meet the requirements for the project. Work was continuous through the winter of 2008-2009 and was finished in late summer of 2009.

Springville Reach Pipeline
Springville, Utah

The Spanish Fork Provo Reservoir Canal Pipeline-Springville Reach is one portion of the overall Central Utah Water Project. This project consisted of 4.8 miles of 60" welded steel raw water pipeline installed using a slide rail shoring system. Along the length of the pipeline were 11 concrete structures of varying sizes and complexity, most with interior mechanical work. The entire pipeline was successfully tested at 450 psi. Besides the 60" pipeline, the project replaced numerous water, sewer, storm drain, and irrigation facilities. Significant traffic control included lane modifications and daily traffic switches on Highway 89, and extensive residential detours. The pipeline passed through the residential streets of Springville for about 3 miles of its total length. Extensive aging underground utilities and wet soil conditions were daily challenges. Work began in December 2009. All 25,300 LF of pipe was installed by October 2010 with the use of three mainline crews.
