Daniel J Diffenderfer

Daniel Diffenderfer serves as a key procurement professional within U.S. Coast Guard Base Honolulu (70Z034), supporting the agency’s mission to sustain maritime operational readiness through strategic acquisition of ship repair, vessel systems maintenance, and shore infrastructure services. He manages a diverse portfolio of contracts aligned with federal acquisition regulations, focusing on technical services that ensure the seaworthiness of Coast Guard assets and the functionality of critical waterfront facilities. His acquisitions typically involve complex maintenance contracts, facility upgrades, and specialized engineering support, requiring deep coordination with technical stakeholders and compliance with Coast Guard engineering standards. Diffenderfer maintains collaborative relationships with a broad spectrum of contractors, including specialized shipyard firms, marine systems integrators, and infrastructure service providers. While no single contractor dominates his award profile, his procurement patterns reflect consistent engagement with vendors possessing maritime maintenance expertise, metal fabrication capabilities, and facility services experience. He prioritizes vendors with proven track records in naval and coast guard environments, fostering long-term partnerships grounded in technical competency and regulatory compliance. His contracting approach demonstrates a strong preference for open competition, with 85.3% of acquisitions conducted without set-aside restrictions. However, he actively supports small business participation, allocating 14.7% of awards to total small business set-asides under FAR 19.5, consistently enabling qualified small businesses to compete for vessel maintenance and facility support contracts without socioeconomic targeting to 8(a), HUBZone, or SDVOSB categories. His primary procurement focus centers on NAICS 561730 (Landscaping Services), reflecting environmental and aesthetic maintenance at coastal installations, and NAICS 336611 (Ship Building and Repairing), underscoring his technical expertise in naval vessel sustainment. Additional emphasis on 336612 (Boat Building) and 561790 (Other Services to Buildings and Dwellings) highlights his role in supporting both fleet and shore-side infrastructure, requiring integrated knowledge of marine engineering, corrosion control, and facility lifecycle management.
