This project is for the construction of Two (2) Munitions Storage Igloos at Ellsworth AFB, South Dakota. The site contains two (2) existing earth- covered munition storage igloos that will need to be demolished that are 5145 square feet (SF) total. The existing structures consist of a thick concrete bunker encased in an earthen berm. Hazardous materials might be present in the existing structure and will need to be accounted for in the budget for proper disposal. The new igloos will be a new Earth Covered Magazine (ECM) to include concrete access pavement, communications, security systems, and utility electrical connection. The new Munition Storage Igloos are based on a Standard Design 421-80-08 REV1 designed by Huntsville MCX (Hayman-type). Each of the new proposed igloos are 80 feet long x 25 feet wide with an area of 2000 square feet (SF). The site work includes regrading around the proposed storage igloos to support positive drainage, new hardstand for access, concrete, and bollards. The site is located within the munition storage area (MSA) and will require escorts throughout all stages of construction. The contractor must coordinate access and inspections of all materials brought into the MSA. Construction Limits will be established within the MSA with temporary fencing. This chain-link fence will meet minimal

requirements and have visual screening material attached to limit views into and out of the construction zone. A temporary working pad may be constructed between the two (2) existing igloos to stage and park any construction equipment. Estimated Project Solicitation Issue date: December 2026 Small Businesses are reminded under FAR 52.219-14(e)(3) General construction, it will not pay more than 85 percent of the amount paid by the Government for contract performance, excluding the cost of materials, to subcontractors that are not similarly situated entities. Any work that a similarly situated entity further subcontracts will count towards the prime contractor's 85 percent subcontract amount that cannot be exceeded. Prior Government contract work is not required for submitting a response to this Sources Sought synopsis. Project

Period of Performance: 540 calendar days from construction Notice to Proceed (NTP). RESPONSES: Please respond to all information requested in this notice not later than 2:00pm Central Time
