Industrial Projects Benefitting from Our Expertise


Inland Empire Energy Center Construction Site

The Conco Companies have been delivering expert concrete services for commercial, educational, entertainment, healthcare, public works, and parking projects as well as for industrial projects. Our portfolio contains several large industrial projects throughout the West Coast such as the United Spiral Pipe LLC (USP) plant, the Inland Empire Energy Center, and the former Solyndra facilities.

Completed in 2010, United Spiral Pipe (USP) is a state-of-the-art spiral welded pipe manufacturing plant in Pittsburg, CA. The enormous rectangular shaped building is 35 ft. tall, more than six city blocks long, and approximately a block and a half wide. As a joint venture of United States Steel Corporation and two South Korean firms, the steelmaker Posco and SeAH, a spiral steel pipe manufacturer, the plant cost more than $130 million to construct. The architect and engineer on the project was the Continental Design And Management Group.

According to the USP website, the plant has world-class pipe making and coating capabilities and can produce 300,000 net tons of API specification line pipe per year in outside diameters ranging from 24 inches to 64 inches. The massive steel pipes are used to transport oil and natural gas for the expanding North America pipe market. Constructed to LEED standards, it exceeds California’s Title 24 lighting requirements and is one of the most advanced and efficient spiral pipe mills in North America to-date.

The Inland Empire Energy Center was constructed in response to the quickly growing, under-serviced energy market in Southern California. The new energy plant was built by the General Electric Company and managing partner, the Calpine Corporation. Located on 46 acres in Romoland, CA. in Riverside County, the plant came online in 2008. The large 800MW, natural gas-fired plant is capable of meeting the energy demands of almost 600,000 households in the area. We invite you to take a look other Conco projects featured on our website.

Since that time, we have taken a leading role as top concrete contractors in the region. We have four regional offices serving California, Oregon, Nevada, Colorado and Washington.
