How to read a federal construction solicitation
A federal construction package looks intimidating because it's standardized, not because it's complicated. Once you know the notice types, the packet's anatomy, and the three or four fields that decide a bid, you can triage one in minutes.
Notice types: what stage is this?
SAM.gov notices follow a lifecycle, and reacting correctly to each stage is half the game:
- Sources sought / RFI — market research, not a bid. Responding (a capability statement and a short email) can shape whether the job becomes a set-aside and puts you on the agency's radar.
- Presolicitation — a heads-up that the solicitation is coming; start your teaming and site-logistics thinking now.
- Solicitation: IFB (Invitation for Bids) — sealed bidding; lowest responsive, responsible bidder wins. Most straightforward construction work runs this way.
- Solicitation: RFP (Request for Proposals) — negotiated procurement; price plus stated evaluation factors (past performance, technical approach). Expect to write, not just price.
- RFQ (Request for Quotations) — simplified acquisitions; faster, smaller, less paperwork.
- Amendments — every change to the package. You must acknowledge amendments in your bid or risk being thrown out as non-responsive.
Anatomy of the packet
A typical package: the solicitation form and clauses (often on SF 1442 for construction), the specifications organized by division, the drawing set, a wage determination, and a stack of attachments — geotech reports, hazmat surveys, phasing plans, bid schedules. The decisive details cluster in predictable places: bonding requirements in the clauses, liquidated damages and period of performance in the contract terms, site-visit and RFI dates in the cover instructions, and the magnitude range in the synopsis.
That predictability is why parsing works: JobsiteBids pulls bonds, prevailing-wage applicability, liquidated damages, licensing, insurance, and key dates out of each packet into structured fields, with anything the documents don't state left blank.
The wage determination (Davis-Bacon)
Federal construction contracts over $2,000 carry Davis-Bacon prevailing-wage requirements — which in practice means essentially every job you'd bid. The wage determination in the packet lists, by labor classification, the minimum hourly rate plus fringe benefits you must pay for site work; determinations come in four flavors (building, residential, highway, heavy) matching the work type.
Price labor off the wage determination, not your private-work rates — the fringe component surprises shops new to federal work. On contracts over $100,000, time-and-a-half over 40 hours is additionally mandated by the Contract Work Hours and Safety Standards Act. Certified payroll reporting comes with the territory; build the administrative hour into your overhead.
A five-minute triage that actually works
Before committing estimator hours: confirm the set-aside (can you win it?), the magnitude (can you bond it? — see bonding explained), the dates (is the site visit still attendable, and is there runway to price it?), and the liquidated damages (can you live with the schedule risk?). Only then does the spec book earn a read.
And watch the amendments after you commit — a moved bid date or revised bid schedule arrives as an amendment, and acknowledging every one is mandatory.
Where the decisive fields actually live
The reason a fourteen-PDF packet is triageable in minutes is that the facts driving a bid/no-bid decision sit in predictable places. You are not reading the package on the first pass — you are locating six fields.
| What you need to know | Where it lives |
|---|---|
| Can we legally win it? | The set-aside field on the SAM.gov notice, before you open anything |
| Is it our size of job? | The magnitude of construction range in the synopsis or the notice body |
| Can we bond it? | The bonding requirements in the solicitation clauses |
| What are we exposed to on schedule? | Liquidated damages and period of performance in the contract terms |
| Is there still runway? | Site visit, question cutoff, and bid due dates in the cover instructions (SF 1442 for construction) |
| What do we have to pay the crew? | The wage determination attached to the packet |
Frequently asked questions
- What is the difference between an IFB and an RFP?
- An Invitation for Bids is sealed bidding: bids are opened publicly and the award goes to the lowest responsive, responsible bidder on price alone. A Request for Proposals is a negotiated procurement where price is weighed against stated evaluation factors such as technical approach and past performance — so an RFP means writing, not just pricing.
- What happens if I don't acknowledge an amendment?
- Your bid can be rejected as non-responsive, regardless of your price. Amendments are how every change to the package is issued, and acknowledging each one in the manner the solicitation requires is mandatory. It is one of the most common reasons an otherwise strong construction bid is thrown out.
- What is a sources sought notice versus a solicitation?
- A sources sought notice is market research posted before a solicitation exists — no award comes from it, but the responses help the agency decide scope and whether to set the work aside. A solicitation is the actual request for bids or proposals. Responding to the first is how you influence the second.
