Marcia K Beckwith Inc.

Marcia K Beckwith Inc., doing business as MKB Construction Co., is a woman-owned small business headquartered in Fairview Heights, Illinois, that has been registered in the System for Award Management since January 2002. The company specializes in construction, repair, renovation, and infrastructure services for the U.S. Department of Defense, with a primary focus on facility maintenance and modernization projects at military installations. MKB Construction Co. has established itself as a reliable partner for the Air Force and Air National Guard, delivering complex construction projects ranging from routine maintenance tasks to multi-million dollar facility upgrades that support operational readiness and regulatory compliance.

MKB Construction Co. has executed an extensive portfolio of federal construction and facility improvement projects, with over 40 prime contract awards documented in recent years totaling more than $20 million since 2020. The company's service offerings encompass HVAC system upgrades and repairs, roofing repairs and replacements, fire suppression system modernization and repairs, electrical system improvements, interior renovations, boiler and controls system repairs, ADA and architectural barrier compliance modifications, chilled water line repairs, CRAC unit repairs, kitchen renovations, storm damage restoration, and general facility maintenance across multiple buildings. The primary funding agency for these awards has been the U.S. Air Force's Air Mobility Command, with secondary awards from the Air National Guard and Air Force Space Command. The majority of MKB Construction Co.'s recent contracts have been delivery orders issued under the Scott Air Force Base Multiple Award Construction Contract (MACC) program, a $90 million indefinite delivery vehicle. MKB Construction Co. has secured contracts both under total small business set-asides and on unrestricted competitive bases, with individual delivery order values ranging from approximately $25,000 for minor repairs to $2.36 million for comprehensive fire suppression system modernization. Notable recent awards include a $2.36 million delivery order for fire suppression system repairs in Scott AFB hangars (September 2025), a $2.32 million contract for multipurpose facility repairs with the Air National Guard (September 2023), a $2.26 million boiler and controls system upgrade (June 2022), and a $2.06 million HVAC component repair project (July 2021).

MKB Construction Co. holds a single Indefinite Delivery Contract (IDC) as a prime awardee: the FY 24 Multiple Award Construction Contract (MACC) Program at Scott Air Force Base, Illinois, awarded by the U.S. Air Force's Air Mobility Command on May 1, 2024, with a ceiling value of $90,000,000 and an ultimate completion date of April 30, 2032. This is a Firm Fixed-Price Indefinite-Delivery Indefinite-Quantity (IDIQ) contract designated as a total small business set-aside with multiple award status, meaning MKB Construction Co. competes alongside other qualified small businesses for individual task orders. Under this MACC vehicle, MKB Construction Co. provides construction, repair, renovation, and general infrastructure services at Scott Air Force Base with potential extension to other Department of Defense installations. The contract scope encompasses facility maintenance, HVAC upgrades, electrical system improvements, roofing repairs, fire suppression system work, and general building renovations, with task orders typically valued between $25,000 and several million dollars. The Air Mobility Command has been the sole agency issuing task orders under this IDC, awarding numerous delivery orders for specialized facility improvements including hangar fire suppression modernization, roof replacements, HVAC repairs, building renovations, chiller repairs, interior room renovations, exterior door repairs, and storm damage restoration. This MACC vehicle has become the primary contracting mechanism through which MKB Construction Co. executes its federal construction work, providing the Air Force with flexible procurement authority to address recurring facility maintenance and capital improvement requirements across the installation while supporting the agency's preference for awarding work to certified woman-owned small businesses.
