Darryl Speller

Darryl Speller serves as Project Manager within the Public Buildings Service’s PBS R11 Construction Services Division Center 1, part of the General Services Administration. In this role, he oversees the end-to-end delivery of federal construction projects across the National Capital Region, with a focus on integrated design-build procurement strategies. He manages the planning, solicitation, and contract administration of mission-critical facility upgrades, ensuring compliance with federal building standards, historic preservation guidelines, and sustainability mandates. His acquisitions are primarily construction-focused, emphasizing modernization of aging infrastructure and the integration of energy-efficient systems to support federal operational continuity. Speller collaborates closely with specialized construction contractors experienced in federal compliance, particularly those with expertise in plumbing, heating, and air-conditioning systems. While specific vendor names are not disclosed, his working relationships are characterized by long-term partnerships with firms that demonstrate proven performance in complex public-sector environments, including those with experience in historic renovation and high-performance building systems. He prioritizes contractors who adhere to rigorous safety protocols and possess the technical capacity to execute design-build deliverables under tight regulatory and schedule constraints. Speller maintains a strict preference for HUBZone-set-aside contracts, directing 100% of his procurement activity toward eligible small businesses located in historically underutilized business zones. This unwavering commitment reflects a strategic alignment with federal socioeconomic goals and ensures meaningful economic opportunity in underserved communities. His contracting patterns consistently prioritize HUBZone-certified firms, reinforcing the agency’s dedication to equitable access and workforce development through federal construction spending. His technical domain is narrowly focused on NAICS 238220—Plumbing, Heating, and Air-Conditioning Contractors—reflecting deep expertise in mechanical systems procurement for federal facilities. He specializes in procuring comprehensive HVAC upgrades, hydronic system replacements, and integrated building automation controls, ensuring compliance with GSA’s sustainability benchmarks and energy performance standards.
