Experienced, credentialed and versatile, OSI is proud to be awarded many contract vehicles, showcasing our ability to fit your specific needs.

This Contract is available to all federal agencies worldwide and its mission is, “to provide expertly managed space, products, services and solutions, at the best value.”

Under this Contract, OSI is able to provide consultation, survey, training, engineering and facilitation services quickly and cost effectively. We offer our specialized consultant service at rates that have been fully negotiated and approved by GSA, making it unnecessary for you to seek further competition, nor make a separate determination of fair and reasonable pricing when placing orders under a Federal Supply Schedule contract vehicle.

Being chosen to participate in this contract speaks to our reputation in our field, as schedule requirements dictate that only well-qualified and performance-tested firms become eligible for the schedule at fair and reasonable prices.

OSI also has multiple vehicles in the Department of Defense (DOD) and the Department of Homeland Security (DHS). Our rates have been fully negotiated by DCAA and the Department of Homeland Security’s Office of Procurement.
