Key takeaways
- Register in SAM.gov with NAICS codes aligned to DOI buying patterns before you chase a solicitation.
- Track DOI forecasts and sources-sought notices — most awards are shaped months before the RFP drops.
- Mirror the Section L instructions and Section M evaluation factors heading-for-heading in your response.
- Quantify past performance with contract numbers, dollar values, periods of performance, and CPARS ratings.
How DOI buys
DOI awards flow through a mix of full-and-open competitions, small business set-asides, and task orders on existing vehicles. Most competitive dollars move through indefinite-delivery contracts, so incumbency on a vehicle is often the real gate. Watch the agency forecast, respond to every relevant sources-sought and RFI, and build relationships with the contracting officer and program office long before the solicitation posts.
What DOI evaluators reward
Technical volumes that are traceable to the statement of work score highest. Evaluators are scoring against a checklist derived from Section M, not reading for prose quality. Give them one clearly labeled response per requirement, show staffing that is realistic against the labor categories and clearances required, and prove risk mitigation with named plans rather than adjectives. DOI evaluators value environmental compliance fluency (NEPA, ESA) and demonstrated ability to work in remote locations.
Common reasons DOI bids lose
Missing a mandatory form or page-limit rule is the top cause of elimination — compliance failures are unrecoverable. After that: generic past performance that isn't same-size, same-scope, and same-complexity; unsupported labor mixes; pricing that can't be traced to the basis of estimate; and technical approaches that describe what the agency already told you instead of how you will deliver it.
FAQ
Do I need a contract vehicle to win DOI work?
Not always, but it helps. Many DOI requirements above the simplified acquisition threshold are competed as task orders on GWACs or agency IDIQs. Subcontracting or teaming with a vehicle holder is a common first step while you build past performance.
Where do I find DOI opportunities?
SAM.gov is the authoritative source for solicitations above $25,000, plus the agency's own procurement forecast for planned buys. RFP Scribe pulls the live SAM.gov feed so you can filter by agency, NAICS, set-aside, and due date.
How long does an DOI proposal take?
Teams typically spend two to six weeks on a mid-size response. RFP Scribe compresses the drafting phase by building the compliance matrix from the solicitation and generating first-draft narrative from your Company Brain.
