P--Demolition Multiple Award Contract (Demo-MAC)This contract is a Multiple Award Contract (Demo-MAC) for demolition services issued by the Bureau of Indian Affairs under the Department of the Interior, specifically set aside for Indian Small Business Economic Enterprises (ISBEE) to support economic development within Tribal communities. The solicitation, numbered 140A1626R0011, was posted on June 5, 2026, with a proposal deadline of July 21, 2026, and targets contractors to perform demolition of a wide range of facilities—including schools, dormitories, detention centers, housing units, offices, museums, and historic buildings—across Indian Country and the Continental United States. The contract’s period of performance runs from September 23, 2026, to September 22, 2031, with a total program ceiling of $120 million over five years, and each awardee is guaranteed a minimum of $10,000 in orders unless off-ramped or fully awarded. Task orders will be issued as fixed-price contracts, typically ranging from $50,000 to $10 million, with any remaining outstanding orders required to be completed within five years of contract award and no deliveries permitted beyond that period. Offerors must be certified as Indian Economic Enterprises (IEE) through the mandatory IEE Representation Form and comply with extensive regulatory requirements, including adherence to FAR and DIAR clauses covering ethics, whistleblower protections, subcontracting limitations, labor standards, and procurement integrity. Compliance with safety standards such as NFPA 70E and OSHA is mandatory, requiring contractors to furnish personal protective equipment and manage hazardous materials like asbestos and PCBs according to federal and state regulations for packaging, labeling, and disposal. Technical proposals must include three to five relevant past projects, a completed Past Performance Questionnaire, and a detailed Seed Project Technical Approach covering personnel qualifications and realistic resourcing strategies, all submitted in PDF format with strict formatting rules including 12-point Arial or Times New Roman font, one-inch margins, and paginated headers. Price submissions require an executed SF1449, corporate authority certification, and completed representations in Section K, all bound separately from the technical volume. Evaluation is based on a best-value trade-off approach where non-price factors—experience, past performance, and technical approach—are weighted equally with price, with any “No Confidence” past performance rating resulting in automatic disqualification. Contractors must register for electronic invoicing via the Treasury
