Colleen Sullivan

Colleen Sullivan supports critical infrastructure procurement efforts for the W072 Endist Buffalo under the Department of the Army, managing acquisitions aligned with the agency’s mission to advance civil works, waterway maintenance, and environmental remediation. She oversees the planning, solicitation, and award of contracts for heavy civil engineering projects, including dredging, dam rehabilitation, and contaminated site restoration, ensuring compliance with federal procurement regulations and mission-critical timelines. Her work directly enables the Army Corps of Engineers’ national defense and environmental stewardship objectives through timely delivery of complex public works. Sullivan maintains a consistent working relationship with MBX BUILDERS LLC, a primary contractor for large-scale civil infrastructure execution. Her procurement patterns reflect a preference for established contractors with demonstrated capability in heavy construction and environmental engineering, often engaging firms with proven experience in federal water resource projects. While she collaborates with a limited core group of high-performing vendors, she also facilitates competitive bidding to ensure accountability and performance excellence across contract phases. Her contracting portfolio reflects a balanced approach to socioeconomic participation, with nearly three-quarters of awards supporting small business participation. While the majority of contracts are unrestricted, she regularly utilizes Total Small Business Set-Asides and has a notable preference for Women-Owned Small Businesses, demonstrating a deliberate commitment to expanding opportunities under FAR 19.5. This pattern underscores a strategic effort to diversify the contractor base while maintaining technical rigor. Sullivan’s primary focus lies in NAICS 237990 (Other Heavy and Civil Engineering Construction), where she procures complex earthmoving, hydraulic structure repair, and navigation channel maintenance services. She also routinely sources specialty trade services—including plumbing, HVAC, and electrical component manufacturing—to support integrated infrastructure modernization. Her technical domain expertise centers on large-scale public works requiring coordination of environmental compliance, geotechnical engineering, and federal water resource regulations.
