Allan Preston

Allan Preston supports the Public Buildings Service’s Region 2 Building Services Branch in executing strategic procurement initiatives to modernize and maintain critical federal infrastructure, including courthouses, ports of entry, and government facilities. He manages the acquisition lifecycle for complex construction and engineering services, ensuring compliance with federal regulations and alignment with GSA’s mission to deliver safe, resilient, and efficient public buildings. His work encompasses full-spectrum contracting for commercial and institutional construction projects, as well as integrated engineering services required for design, structural assessment, and facility upgrades. Preston plays a pivotal role in translating agency infrastructure needs into legally compliant, performance-based solicitations that prioritize lifecycle cost efficiency and long-term operational readiness. Preston collaborates with a diverse pool of qualified contractors, primarily general contractors with expertise in federal construction and licensed engineering firms specializing in civil, structural, and MEP systems. While no single vendor dominates his portfolio, he consistently engages firms with proven experience in federal facility projects, emphasizing pre-qualified contractor lists and past performance evaluations. His contracting approach prioritizes competitive sealed bidding and negotiated procurements under FAR Part 14 and Part 15, fostering transparent, merit-based selection processes that ensure technical competence and schedule reliability. Preston’s procurement strategy reflects a strong preference for open competition, with 100% of acquisitions conducted without set-aside designations. This indicates a focus on selecting the most technically capable and cost-effective offerors regardless of socioeconomic status, consistent with the agency’s need for specialized, large-scale capabilities in high-risk federal construction environments. While small business participation is not formally prioritized through 8(a), HUBZone, or SDVOSB set-asides, he remains compliant with all small business subcontracting requirements under applicable contract clauses. His primary procurement focus lies in NAICS 236220 (Commercial and Institutional Building Construction) and 541330 (Engineering Services), reflecting deep expertise in managing integrated design-build and construction management contracts. He routinely procures services related to structural renovation, seismic retrofitting, HVAC modernization, and building systems integration, requiring precise technical specifications and rigorous performance metrics to ensure compliance with federal building codes and sustainability standards.
