SMITHSONIAN INSTITUTION.SMITHSONIAN INSTITUTION.SMITHSONIAN INSTITUTION · Response deadline: Mon, 09 Nov 2026
What the government is buying
The Smithsonian Institution is seeking an Indefinite Delivery Indefinite Quantity (IDIQ) contract for construction services in the Washington, D.C. metropolitan area. An IDIQ structure means the government establishes a master agreement with one or more vendors and then issues individual task orders for specific projects as needs arise. This arrangement works well for ongoing maintenance, repairs, renovations, and new construction work that varies in scope and timing.
Under NAICS code 236220, this falls under Commercial and Institutional Building Construction, which covers construction of non-residential buildings including museums, offices, educational facilities, and similar institutional structures. The Smithsonian operates numerous museums, research centers, and historic properties across the National Mall and beyond, creating diverse construction needs ranging from exhibition space renovations to building systems upgrades.

Who can bid
This opportunity is 100% set aside for small businesses under the Small Business Set Aside - Total program. To compete, your business must:
- Meet the SBA size standard for NAICS 236220, which is based on average annual receipts (see the solicitation for the specific threshold, which SBA periodically updates)
- Be registered and active in SAM.gov with the appropriate NAICS code
- Hold any required surety bonding capacity for construction work
- Demonstrate relevant past performance in commercial or institutional construction
Certified 8(a), HUBZone, SDVOSB, or WOSB firms that are also small businesses under this NAICS may bid, though no additional preference applies beyond the total small business set-aside. Joint ventures are permitted under SBA rules but must comply with affiliation and control requirements.
How to put together a competitive bid
Construction IDIQ competitions typically emphasize technical capability, pricing strategy, and past performance. Focus on these elements:
Team and capability: Demonstrate experience with federal or institutional clients, particularly historic preservation or occupied-building work if relevant to Smithsonian properties. Highlight your project management systems, safety record, and quality control processes.
Pricing structure: IDIQ contracts typically require a pricing schedule for common construction tasks (e.g., per-square-foot costs, unit prices for trades, overhead rates). Develop competitive yet realistic pricing you can sustain across multiple task orders. The ceiling amount and ordering period length are critical for financial planning—see the solicitation for specifics.
Past performance: Prepare relevant project summaries with comparable scope, complexity, and contract value. Include client contact information for verification. Federal references strengthen your submission.
Bonding and financials: Verify your surety backing can support the anticipated task order range. Construction contracts often require performance and payment bonds.
Small business documentation: Ensure your SAM profile, SBA size standard self-certification, and any certification documents are current and accurate.
