The City of Billings awarded the Aronson Road and Bridges Project to COP Construction LLC in January, 2008. The $5.6 million dollar project was for the construction of two bridges and 3000 feet of new asphalt road to provide another new access to Billings Heights from Airport Road. Contract time required completion of all work by October, 2008. The showcase of the project involved a new bridge over Alkali Creek. This bridge was a 200 foot single span steel girder structure, on a curve, and with a cast in place concrete deck and walkways. The girders required for the project weighed 630 tons and were supplied to COP Construction LLC by Roscoe Steel, also of Billings, MT. Additional project improvements included MSE walls, street lighting, storm water pipe, inlets, and outfall structures, extension of the water main, and major street landscaping.

In 1915 the City of Billings purchased its waterworks from Montana Water Company at a cost of $315,000. The original waterworks plant was built in 1886-87, and at that time, the City had a population of approximately one thousand.
Since then the City of Billings Water Treatment Facility (aka Gerald D. Underwood Water Treatment Plant) has continued to expand in an ongoing effort to keep up with the growth of Billings. The source of supply for the City's waterworks is the Yellowstone River. The nominal capacity of the water treatment plant is about 50 million gallons per day (MGD). Daily average usage is approximately 24 MGD, however at peak times during the summer months the plant will process at capacity-50MGD.
Water is pumped from the plant to eleven different zones within the City, and a 600-foot elevation differential exists between the highest and lowest portions of the City's water service area. The plant currently services approximately 115,000 people.

Current Expansion
In 2005 the City of Billings contracted with COP Construction LLC, a prominent, local, municipal general contractor to both renovate and expand the Underwood facility. This is a very technically challenging project in many respects, especially in light of the fact that this is a renovation/expansion around an ongoing operation. The completed project is estimated at $17 million and will take about two years to complete. When completed, the treatment plant's capacity will increase about 20% or to a capacity of 60MGD. This should serve the City's population well into the future.

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.
