Customer: City of Steamboat Springs
Scope: General Contractor for Wastewater Treatment
Plant Expansion Project
Cost: $9 Million
Location: Steamboat Springs, Colorado

Civil Constructors served as the general contractor to expand the Steamboat Springs Wastewater Treatment Plant. Working closely with both the City of Steamboat Springs and McLaughlin Water Engineers, this two-year project was completed on time and within the owner's budget. The project team used new technologies for both the new construction and modifications to the existing facilities, developing new and innovative methods to meet the project's specifications.

Subgrade over excavation requirements and extensive yard pipe installation called for large quantities of specifically graded fill and bedding materials. Using knowledge of the subsurface soil makeup from the boring logs, Civil processed (crushed) the large volume of new structure excavation material on site to generate all of the required fill and bedding. This resulted in considerable purchase and hauling cost savings associated with imported materials.

Civil also designed and constructed specialized gang form wall panels to enable the large lower wall fillets to be poured monolithically with the exterior structure and partition walls. This expedited construction of the walls at a lower unit cost, and provided a better product to the owner.

Continual efforts to maintain open communication and good standing with the owner and engineer, along with a mindset of providing the owner with the best product, helped the product to be completed smoothly and be completed on schedule.

Galena Ave. Bridge
Customer: Illinois Department of Transportation
Scope: Replacement of the Galena Avenue Bridge while under two-way traffic
Cost: $17.3 Million
Location: 713' Crossing of the Rock River in Dixon, Illinois.

Civil Constructors was the general contractor to replace a 60-year-old bridge across the Rock River in Dixon, Illinois. Through the direction of Project Manager, Jeff Boldt and Project Superintendent, Russ Thruman, this project used causeways, sectional barges and mechanical winches to access the construction of three piers and four spans crossing the Rock River in downtown Dixon.

IDOT wanted to minimize the inconvenience to the general public as much as possible, so an aggressive schedule along with unusually large penalties was incorporated into this contract. In addition, they required that two lanes of traffic be open at all times while building the new structure in the same location.

The project involved removal of an existing eight-span arched concrete superstructure and replacing it with a four-span arched welded plate girder and concrete superstructure. The existing bridge was roughly 60 foot wide, while the new bridge was to be 100 foot wide.

Because the project had to be built fast, good access was a key. Basically, work near piers #1 and #3 were done off rock causeways while work done at pier #2, near the middle of the river, was accessed using a sectional barge. The barge measured 60' by 130' and was big enough to float a 65 ton and a 110 ton crane, plus over 100 ton of plate girders.

In all, this massive project incorporated 90 semi-loads of welded plate girders, over 800 loads of redi-mix concrete, and 25 semi-loads of reinforcing bars.

Sinnissippi Dam
Customer: Illinois Department of Natural Resources
Scope: General Contractor for Reconstruction of the Sinnissippi Dam
Cost: $9.5 Million
Location: 1335' Crossing of the Rock River in Rock Falls, Illinois.

Civil Constructors served as the general contractor to reconstruct the 100 year old bridge and dam across the Rock River in Rock Falls Illinois. Through the direction of Project Manager Eric Loomis and Project Engineer Chad Terry, this project used the combined talents of both our Freeport and Moline employees to bring this two-year project to completion on time and within our budget.

Through the use of an old structure upstream, a cofferdam was created to control the flow of the Rock River. This resulted in considerable cost savings associated with imported materials.

Civil also used an EFCO gang form system to enable crews to place concrete daily. This expedited construction of the concrete spillway portion of the project, and provided a better product to the owner.

Continual efforts to maintain open communication and good standing with the owner and engineer, along with a mindset of providing the owner with the best product, helped the project to be completed smoothly and be completed on schedule.
