FAR 52.236-27—Site Visit (Construction).
Plain-English Summary
FAR 52.236-27, Site Visit (Construction), is a solicitation provision used in construction acquisitions to tell offerors that they are expected to inspect the project site before submitting an offer or quotation. It specifically ties the site-visit requirement to the construction clauses that will be included in the resulting contract: FAR 52.236-2, Differing Site Conditions, and FAR 52.236-3, Site Investigations and Conditions Affecting the Work. The provision explains how site visits will be handled in two ways: either by giving offerors contact information so they can arrange visits during normal duty hours, or, under Alternate I, by announcing an organized site visit with a set date, time, and meeting location. In practice, this provision helps reduce later disputes about site conditions, access, and contractor assumptions by encouraging pre-bid inspection and making clear that the contractor bears responsibility for understanding visible site conditions. It is especially important in construction because site conditions can materially affect cost, means and methods, scheduling, and risk allocation. The provision also supports fair competition by giving all prospective offerors the same opportunity to inspect the site and gather information before pricing their work.
Key Rules
Site inspection is expected
Offerors or quoters are urged and expected to inspect the site where the work will be performed. This is not merely optional language; it signals that bidders should investigate the physical conditions before pricing the work.
Differing site conditions clause applies
The solicitation must state that FAR 52.236-2, Differing Site Conditions, will be included in the resulting contract. This matters because it allocates risk for unknown or unusual site conditions and gives the contractor a contractual remedy in appropriate cases.
Site investigations clause applies
The solicitation must also state that FAR 52.236-3, Site Investigations and Conditions Affecting the Work, will be included in the resulting contract. This clause reinforces that contractors are responsible for examining the site and considering conditions that could affect performance.
Arrange visits during duty hours
Under the basic provision, site visits may be arranged during normal duty hours by contacting the named government representative at the listed address and telephone number. The solicitation should provide enough contact information for offerors to schedule access efficiently.
Organized visit option
Under Alternate I, the agency may schedule an organized site visit instead of individual arrangements. The alternate must specify the date, time, and meeting location so all participants receive the same access opportunity.
Equal access and clarity
Whether the visit is arranged individually or organized by the agency, the provision is intended to give all prospective offerors a fair chance to inspect the site and obtain the same basic information. The government should avoid ambiguity about when, where, and how the visit will occur.
Responsibilities
Contracting Officer
Include this provision in the construction solicitation as prescribed, identify the contact person and site-visit logistics, and ensure the solicitation clearly states whether visits are arranged individually or through an organized event. The contracting officer should also make sure the resulting contract will include the Differing Site Conditions and Site Investigations clauses.
Agency/Technical Representative
Provide accurate site-visit coordination details, host or facilitate access during normal duty hours, and, if using an organized visit, set the date, time, and meeting location. The agency should ensure prospective offerors receive the same practical opportunity to inspect the site.
Offeror/Quoter
Inspect the site or otherwise make a reasonable site investigation before submitting an offer or quotation. The offeror should use the visit to identify visible conditions, access constraints, staging issues, and other factors that may affect price, schedule, and performance.
Contractor
After award, rely on the contract clauses and the pre-award site investigation to manage site-related risk. The contractor must not assume that later claims will succeed if the conditions were reasonably discoverable during the site visit or through required investigation.
Practical Implications
This provision is a major risk-management tool in construction contracting: it pushes bidders to look at the site before pricing, which reduces surprises and disputes later.
A common pitfall is treating the site visit as optional in practice; even though the language says "urged," contractors who skip the visit may still be held responsible for conditions they could have discovered.
Another pitfall is incomplete solicitation information: if the government does not clearly identify the contact person, access process, or organized-visit details, bidders may not have a fair opportunity to inspect.
Contractors should document what they observed during the visit and use that information when preparing pricing, means-and-methods assumptions, and questions before bid due date.
Contracting officers should ensure the site-visit instructions are consistent with the actual site access rules and security requirements, especially where entry is restricted or coordination is needed in advance.
