The Department of Defense, specifically the U.S. Army Corps of Engineers, Louisville District, intends to award a sole source modification to Burns & McDonnell Engineering Company, Inc. for the additional design of a Dedicated Outside Air System (DOAS) as part of the renovation of Building 2245 at March Air Reserve Base, CA. This modification involves expanding the existing design scope to include the integration of a DOAS, which will require rerouting and adding ductwork and reconstructing the exterior screening wall, while working in conjunction with the ongoing full design efforts for the facility. The modification is deemed necessary due to the additional costs and scope that exceed the original task order, and interested parties are invited to demonstrate their capability to provide similar services by submitting their information to the primary contact, Bonny Dylewski, by June 27, 2025, at 10:00 a.m. Eastern Time.
