William P. Gelberg Inc. specializes in advanced manufacturing and precision fabrication services under NAICS 339950, focusing on the design, development, and production of specialized components and systems for government applications. The company leverages technical expertise in metalworking, prototyping, and quality-controlled assembly processes to deliver mission-critical hardware solutions that meet stringent federal specifications. Their capabilities include CNC machining, tolerancing to micro-inch standards, material certification, and adherence to AS9100 and ISO 9001 quality frameworks, ensuring reliability in high-stakes environments. A key differentiator is their ability to support low-volume, high-complexity production runs with rapid turnaround, making them a trusted partner for custom engineering needs that commercial manufacturers cannot efficiently address. While award history is not available to confirm specific agency engagements, the firm’s technical profile suggests alignment with defense, aerospace, and scientific research sectors where precision-manufactured parts are essential. Their operations are likely tailored to support procurement cycles involving small business set-asides, particularly in areas requiring certified fabrication of non-standard hardware. The company is positioned as a niche manufacturer serving government markets that demand certified, small-batch production with rigorous documentation and traceability. Their focus on NAICS 339950 indicates deep specialization in other miscellaneous manufacturing, including custom tooling, instrumentation housings, and electro-mechanical assemblies. As a woman-owned small business headquartered in Washington, D.C., William P. Gelberg Inc. benefits from federal procurement preferences and maintains a strategic presence in the nation’s capital, facilitating close coordination with federal procurement offices and technical stakeholders. The company holds formal certification as a Woman-Owned Business, enhancing its eligibility for targeted contracting opportunities.

Stotfold Town Council is seeking experienced contractors for the renovation of the Cemetery Toilet Block, a project with an estimated budget of 190,000 to 210,000 GBP including VAT.
