Department of the Interior (DOI)

The Department of the Interior (DOI) is the federal agency responsible for managing and conserving the nation's natural resources and cultural heritage, overseeing approximately 480 million acres of public lands, administering trust responsibilities to more than 570 federally recognized tribes, and generating billions in revenue from energy and mineral leasing on federal lands.

What is the Department of the Interior?

DOI manages nine major bureaus and offices with distinct procurement needs. The Bureau of Land Management (BLM) oversees energy development leasing, range management, and recreation on federal lands. The National Park Service (NPS) manages 400+ park units requiring facilities management, concession services, and construction contracts. The Bureau of Indian Affairs (BIA) provides services to tribal governments. The Bureau of Reclamation operates western water infrastructure. The U.S. Fish and Wildlife Service manages wildlife refuges and endangered species programs.

DOI contracting spans environmental and natural resource management services, scientific research and monitoring, IT systems, construction and facilities management (particularly in national parks), fire management support, water infrastructure operation and maintenance, and tribal government services support. The acquisition workforce is distributed across bureaus, with the Office of Acquisition and Property Management (PAM) providing policy oversight.

Government contractors pursuing DOI opportunities should focus on agency procurement forecasts published through bureau-specific forecast portals, BPA and IDIQ vehicles (including the Interior Department's agencywide IT vehicle EITAAC), and set-aside opportunities under the Buy Indian Act (25 U.S.C. § 47), which authorizes preferences for Indian-owned businesses on contracts benefiting Indian programs.

Why DOI matters for government contractors

DOI obligates approximately $3-4 billion annually in contract spending. Environmental services, natural resource management, and IT modernization are consistently high-spend categories. Contractors with expertise in environmental science, GIS, wildfire management, or tribal government services have significant opportunities across DOI bureaus.

Example

An environmental services firm wins a five-year IDIQ contract with the Bureau of Land Management to conduct environmental impact assessments for proposed energy projects on federal lands. The firm provides interdisciplinary teams of biologists, archaeologists, and environmental engineers who evaluate project impacts and prepare documentation required under the National Environmental Policy Act (NEPA). The contract includes small business set-aside task orders for tribal monitoring services under the Buy Indian Act.

Frequently Asked Questions

What is the Buy Indian Act and how does it affect DOI contracting?

The Buy Indian Act (25 U.S.C. § 47) authorizes DOI to use Indian-owned businesses preferentially when procuring goods and services for the benefit of Indian programs. Unlike typical set-asides that require competition among certified firms, the Buy Indian Act authorizes direct awards to Indian-owned businesses when economically justified. This creates significant opportunities for Native American-owned businesses doing work with BIA and tribal programs.

What NAICS codes are most common in DOI contracting?

Common NAICS codes in DOI contracting include 541620 (Environmental Consulting Services), 541370 (Surveying and Mapping), 237990 (Other Heavy and Civil Engineering Construction), 561210 (Facilities Management), and 518210 (Data Processing). Natural resource management and scientific services represent a significant share of DOI's services spending.

Does DOI have its own contract vehicles?

Yes. DOI maintains agencywide contracts including the EITAAC (Enterprise Information Technology Acquisition for the Americas) vehicle for IT services, and bureau-specific IDIQs for environmental services, facilities management, and professional services. Contractors should register on relevant DOI IDIQ vehicles to access task order competitions.

Where can contractors find DOI procurement forecasts?

DOI's main procurement forecast is published annually through the DOI Acquisitions website. Individual bureaus (BLM, NPS, FWS, Bureau of Reclamation) also publish bureau-specific forecasts. SAM.gov is the primary portal for active solicitations and contract award notices.
