The Defense Information Systems Agency seeks contractor services to renovate and expand Building 11, Section 13 at Defense Supply Center Columbus in Columbus, Ohio, with proposals due October 7, 2026 at 2:00 PM CST. This is a Total Small Business set-aside.

Place of performance is Columbus, Ohio. The scope expands the current 4,700 square foot space by adding 3,450 adjacent square feet through demolition of existing furniture and office partitions; installation of new partitions, flooring, wall base, and furniture; and renovation or modification of existing HVAC equipment. The contractor is also responsible for electrical work, communication and data cabling and connections, and mechanical work. Composite cable and conduit, ceiling tile, and a conference table are optional. The NAICS code is 561210, Facilities Support Services, and the PSC code is Z2AA, Repair or Alteration of Office Buildings.

The period of performance is 365 days from award.

The government will remove all electronic items and equipment before demolition; temporary occupancy for 10 people begins February 1, 2026. Construction-level drawings are the first submittal; the government allows ten business days for review of each deliverable.

Evaluation uses a Lowest Price Technically Acceptable (LPTA) methodology across four subfactors: Project Schedule, Systems Furniture, STC Rated Walls & Secure Space, and Mechanical/HVAC Modifications.
