Worked example · US federal contract bid writing
A lowest-price technically-acceptable small business set-aside for one 5,100 sq ft building. Under LPTA the price gets you looked at and the paperwork keeps you in; we show both.
Worked example against a live public notice. The notice is real and publicly available. The bidder, Fairlead Custodial Services LLC, is a fictional company with invented facts, written to show our method. This is not client work and no bid was submitted.
The public notice (real)
The notice may have closed or changed since we read it. Always work from the current version on the portal.
The bidder (fictional)
Commercial janitorial services · Bourne, Massachusetts, on the Upper Cape and a short drive from the base · 14 employees: owner, one working supervisor, 12 part-time cleaners
Every fact about this company is invented for the example.
Step 1 · Read the notice
Step 2 · Gates
Registration, set-aside and size (3.3.1-33; 3.6.1-17; 3.6.1-7)
SAM.gov registration is active (invented); check the renewal date falls after 20 October. Total small business set-aside under NAICS 561720 at $22 million; the firm is well under it and self-performs, so Limitations on Subcontracting are not a problem.
Insurance certificate (SA18; AMS 3.4.1-10)
A certificate meeting the AMS clause for work on a Government installation must be in the offer. The broker has not yet confirmed the wording (invented). Get it in writing before the first draft, not the last.
Base access (SOW 1.08)
All staff hold REAL ID-compliant licences (invented). Vetting at the Pass and ID Office happens after award, but a refused worker would leave a two-person crew short, so a trained reserve is named in the technical proposal.
Past experience: three similar contracts in five years (Section M Factor A)
Three contracts of similar scope exist (invented), but each must be documented against items (a) to (i). One missing field makes the offer non-responsive. Similar size matters too: the building is 5,100 sq ft, so small sites are a fit, not a weakness.
Past performance: three third-party surveys (Section M Factor B)
References must send Attachment J-3 to the Contracting Officer themselves before 3:00 PM ET on 20 October. Surveys sent by the bidder are not accepted. This depends on three busy people doing something for you on time.
Deadline
Five and a half weeks. Site visit RSVP by 22 September, questions by 2 October. Enough time if the reference chase starts this week.
Step 3 · The honest call
Step 4 · The matrix
Instructions tell you how to submit. Evaluation criteria tell you how you are scored. The matrix holds both together.

Step 5 · Response excerpt (fictional bidder)
Building 130 is 5,100 sq ft, about 2,258 sq ft of carpet and 2,643 sq ft of tile. We would staff it with one working supervisor and one cleaner, Monday to Friday. SOW 2.01 and 2.02.G require work to start before 3:00 PM Monday to Thursday and before 12:00 PM on Friday; our crew would start at 1:00 PM and 10:00 AM respectively and finish the daily list in the same visit. A trained reserve cleaner would be vetted at the Pass and ID Office at the same time as the crew, so a sick day does not become a missed service. No service is planned on the eleven federal holidays in SOW 1.07.
Every visit is recorded on the daily checklist (SOW 1.04.B(2)): one sheet per day listing the SOW 2.02.A tasks by room, signed by the worker who did them and countersigned by the supervisor. The month's sheets are attached to the invoice, which is what the SOW says the COR uses to approve payment. Any deficiency the COR raises on a daily inspection is corrected the same day at no cost (SOW 1.06); the supervisor's mobile number goes to the COR at the start of the contract and the reserve cleaner is the second call.
Periodic tasks run to a twelve-month calendar handed to the COR in the first week of performance: weekly damp-mop and buff of the tile and washing of the glass door entries; monthly spot-scrub and spray-wax, lavatory doors and partitions, and the stairwell; quarterly high dusting and inside-and-out washing of the 18 large and 3 small windows with their shades; semi-annual strip and rewax, light fixtures and receptacles, and shampoo of all carpet; annual cleaning of interior walls (SOW 2.02.B to F). Strip and rewax and carpet shampoo are booked for Fridays after the daily service, using the low-speed machine and extractor we own.
We supply the paper towels, liquid soap, two-ply toilet tissue and liners (SOW 1.02) and keep a two-week stock in the janitor closet with the SDS binder. Equipment stays on site only with the COR's agreement; otherwise it travels on the van. The certificate of liability insurance under AMS 3.4.1-10, the completed J-2 Staffing Access Questionnaire and the price breakdown showing direct labor hours per period are in the offer as SA18 requires.
Relevant experience excerpt (fictional facts)
Fairlead Custodial Services LLC has cleaned a 6,000 sq ft town library five nights a week since 2021 (about $42,000 a year), a 4,500 sq ft credit-union branch since 2022 (about $30,000 a year) and an 8,000 sq ft medical office suite since 2023 (about $45,000 a year). Each is a fixed monthly price covering daily service, periodic floor care and consumables, and each has been renewed at least once. None of the work is subcontracted.
For each contract the past experience section gives the items Section M lists at (a) to (i): title and contract number, client contact name, phone and email, annual value, the full task list and frequencies, percentage subcontracted (zero), start and current end dates, and a statement that there have been no disputes, claims or schedule failures. Each of the three clients has agreed to complete Attachment J-3 and send it to the Contracting Officer directly; we have asked them to copy us so we know it has gone.
We have not held a federal contract before. The solicitation as read does not require one, but it does require the documentation to be complete and the surveys to arrive before 3:00 PM ET on 20 October. That is the part of this offer we would manage most closely.
