Cleaning contracts are won and lost in hallways, not just on a SAM.gov abstract. Square footage in a statement of work can be right and still miss the locked wing that can only be cleaned after 7 p.m., the break room that is a second kitchen, or the security line that adds 20 minutes to every shift change. A site visit — sometimes called a pre-bid walkthrough, pre-proposal conference, or site inspection — is how you see those things before you put a number on paper.
This is general information for small cleaning contractors, not legal advice and not a substitute for the official solicitation. BidBeacon is not affiliated with SAM.gov or any government agency.
What the official rules actually say
When an agency includes FAR provision 52.237-1, Site Visit, the text (April 1984 version, still the current provision as of the FAR page checked for this guide) tells offerors they are “urged and expected to inspect the site where services are to be performed” and to satisfy themselves about general and local conditions that may affect the cost of performance, to the extent the information is reasonably obtainable. It also says that failure to inspect the site is not grounds for a claim after award.
In plain language: if you skip the walk and later discover that trash must be carried to a dock two buildings away, that is generally your problem, not a change-order opportunity. Always read the clause actually printed in your solicitation; agencies can add local instructions on top of the FAR provision.
A site visit and a pre-proposal (or pre-bid) conference are sometimes combined and sometimes separate. The conference is for questions and administrative clarifications. The walk is for conditions. Both will have rules in the notice.
First: is the visit required, optional, or “optional but necessary”?
Open the official SAM.gov notice and look for site-visit dates, RSVP cutoffs, security instructions, and any sentence that says attendance is mandatory in order to submit an offer. Those sentences control.
- Mandatory attendance: if you do not sign in as required, your offer may be rejected. Calendar the RSVP date, not just the walk date.
- Optional attendance: you may still bid, but you are pricing blind wherever the written documents are thin. For janitorial work, “optional” is often still wise.
- No visit scheduled: you may ask the point of contact, in writing and before the question deadline, whether a walkthrough will be offered. Do not show up unannounced at a federal building.
The notice will also say who may attend (often a limit per firm), what identification to bring, and whether non-citizens need extra time for clearance. Follow those instructions exactly. A late RSVP is frequently a no.
Before you go
Re-read the performance work statement, the quality standards, the pricing schedule, and any floor plans or equipment lists. Make a walk sheet so you are not improvising in a noisy corridor. Useful prompts for janitorial work include:
- Hours the building is occupied versus the hours you are allowed to work; alarm and escort rules.
- Actual areas in scope: restrooms, offices, clinics, hangars, barracks, outdoor smoking areas, gyms, childcare rooms, holding cells, or secure spaces with special standards.
- Surfaces and fixtures: restroom counts, flooring types, glass, kitchenettes, loading docks.
- Government-furnished equipment versus contractor-furnished (vacuums, autoscrubbers, consumables, can liners).
- Utilities, janitor closets, water, and whether chemicals must be stored to a specified standard.
- Trash, recycling, medical or hazardous waste (do not guess; if it is in scope, get it in writing).
- Parking, badging, loading access, and union or wage-determination issues you already saw in the attachments.
- Staffing constraints: continuous presence, day porter versus after-hours, emergency call-back.
Bring a way to take notes the site will allow. Some federal facilities prohibit photos. Ask before you photograph anything, including a restroom or a badge desk.
During the walk
Stay with the group. The government technical representative or contracting staff will usually show in-scope areas only. If a door is not opened, ask whether that space is in the contract. If two buildings are on the map and you only see one, say so.
Ask questions in the format the office requested. Many offices will not give a binding answer in the hallway; they will collect questions and post written answers in an amendment. That is a feature. A verbal “we usually don’t worry about that” will not help you later. Get the issue into the official Q&A.
Sign the attendance sheet if there is one, and keep your own record of who from your firm attended, the date, and the escort’s name.
After the walk
Refresh the SAM.gov notice for an amendment that may change the due date, add minutes, or correct the statement of work. Price the job you saw, not the job you hoped to see. If the walk revealed that you cannot staff the hours or meet a clearance requirement, a no-bid is appropriate.
If you are new to federal work, this is a good moment to call your APEX Accelerator. A counselor cannot walk the site for you, but they can help you organize questions and read the amendment that follows the visit.
How this ties back to the notice
Site-visit rules live in the same opportunity as the due date, the time zone, and the attachments. Our guide on how to read a SAM.gov notice covers those fields. A walkthrough does not replace the wage determination or the quality standard in the file. It tells you whether your labor estimate for those standards is fantasy.

Finding notices that may include a walkthrough
Search SAM.gov for free (NAICS 561720 is the janitorial code) and open each official notice for site-visit language. BidBeacon’s free, 7-day-delayed state pages also list still-open federal janitorial notices for states including Alaska, Colorado, Missouri, South Dakota, Utah, and Virginia, at https://bidbeaconalerts.com/bids/. Because those pages are delayed, do not use them as your only calendar for an RSVP — confirm dates on SAM.gov as soon as you can. If you want earlier visibility, BidBeacon’s daily alerts have a 14-day trial at $39/month. Either way, the official notice is the document you follow.
