URS has received a five-year contract extension from WRB Refining for providing mechanical maintenance and construction services at the Wood River Refinery at Roxana in Illinois, US.

URS will perform general mechanical maintenance, capital projects, and turnaround services on refinery equipment, under the contract.

The refinery produces gasoline, diesel and jet fuels, as well as asphalt, propane and chemical feedstock with the capacity to process and refine around 314,000 barrels per day of light and heavy crude oil.

URS energy and construction president George Nash said the company is continuing its two decades of service at the Wood River Refinery.

"With its high level of expertise, our integrated team of URS and WRB Refining personnel works together to keep the facility operating in peak condition, and we are pleased to continue this partnership," Nash added.
