About the company
Southwest Siteworks LLC is a self-certified small disadvantaged business based in Arizona that provides construction, road maintenance, and environmental services. It operates as a sole proprietorship limited liability company.
Through prime contract awards, Southwest Siteworks LLC has provided mechanical hazardous fuel reduction services to the Department of the Interior Fish and Wildlife Service. This included a $144,460 purchase order for vegetation management work at the Buenos Aires National Wildlife Refuge in Arizona. The contract was set aside for small businesses and had a firm fixed-price with a March 2024 completion date. Southwest Siteworks LLC has also performed road maintenance, construction, and disaster recovery activities for the U.S. Forest Service. This encompasses routine treatments like sign installation, drainage work, slope stabilization, guardrail repair, and surface blading on unpaved roads, as well as emergency response tasks like hazard removal and culvert replacement after events like wildfires.
Southwest Siteworks LLC currently holds two major single-award blanket purchase agreements (BPAs) from the U.S. Forest Service. One BPA valued at $50 million provides road engineering, maintenance, and construction services across six national forests in Arizona through February 2033. The other $50 million BPA covers similar road work plus disaster recovery treatments in New Mexico through December 2032. Under these vehicles, Southwest Siteworks LLC can receive task orders for a comprehensive range of road system support activities, from routine vegetation management and surface treatments to complex drainage installations, bridge construction, and post-fire rehabilitation work. The Forest Service issued these BPAs without set-asides to establish long-term sources for road maintenance and construction requirements across the Southwestern Region's diverse terrain.
