FAR 52.247-5—Familiarization with Conditions.
Plain-English Summary
FAR 52.247-5, Familiarization with Conditions, is a transportation clause used in solicitations and contracts for transportation or transportation-related services. It requires offerors to investigate and understand the conditions under which the work will be performed, including any difficulties, site-specific circumstances, and safety precautions, before pricing and committing to the work. The clause also makes clear that a contractor cannot later avoid responsibility for performance or claim relief simply because it failed to inspect the work environment or review available information. In practice, this clause shifts the risk of inadequate pre-bid investigation to the offeror and helps the Government obtain realistic pricing and reliable performance for services that may involve unique routes, facilities, hazards, weather, access issues, or other operational constraints. It is intended to reduce disputes over “unknown” conditions by putting bidders on notice that they must do their homework up front.
Key Rules
Applies to transportation services
This clause is prescribed for solicitations and contracts involving transportation or transportation-related services. Its purpose is to ensure offerors understand the operating environment before submitting a price or agreeing to perform.
Offeror must investigate conditions
The offeror is required to become familiar with all available information about the work site, route, service environment, and any difficulties that may be encountered. This includes reviewing information that is reasonably available before award.
Safety precautions must be considered
The clause specifically calls out safety precautions as part of the conditions the offeror must understand. Offerors should account for hazards, protective measures, access restrictions, and any operational safety requirements in their planning and pricing.
No relief for failure to inspect
If the offeror fails to investigate or learn the available information, it is not relieved from properly estimating the difficulty or cost of performance. The contractor bears the risk of underestimating the work because of inadequate pre-award inquiry.
Responsibility for estimating remains with offeror
The clause places responsibility on the offeror to accurately assess performance difficulty and cost. This means the Government is not responsible for correcting a bidder’s assumptions that could have been avoided through reasonable familiarization.
Responsibilities
Offeror
Review all available information about the work, including site conditions, operational difficulties, and safety precautions; conduct any reasonable investigation needed to understand the services; and prepare its proposal based on an informed estimate of performance difficulty and cost.
Contractor
After award, perform the services with the understanding that it assumed the risk of inadequate pre-award familiarization; manage performance in light of the known or knowable conditions; and avoid seeking relief based solely on a failure to investigate before bidding.
Contracting Officer
Include the clause when prescribed for transportation or transportation-related services; make available relevant information that is reasonably available; and ensure offerors are on notice that they are expected to investigate conditions before pricing.
Agency/Requirement Owner
Provide or identify available information about the work environment, difficulties, and safety considerations so offerors can make informed proposals; support accurate solicitation planning by describing known conditions as clearly as practicable.
Practical Implications
Offerors should treat this clause as a warning that pricing errors caused by poor site familiarization are usually their own risk, not a basis for later adjustment.
Before submitting a proposal, contractors should inspect locations, review maps, routes, weather patterns, access limitations, security rules, loading/unloading constraints, and safety requirements where relevant.
A common pitfall is assuming transportation work is routine when local conditions make it unusually difficult or costly; the clause is designed to prevent that mistake.
Contracting officers should ensure the solicitation package includes enough available information to support meaningful familiarization, even though the clause still places the burden on the offeror to investigate.
Disputes often arise when a contractor claims it did not know about a condition that was reasonably discoverable; this clause weakens those claims if the information was available before award.
Official Regulatory Text
As prescribed in 47.207-1 (d) , insert the following clause in solicitations and contracts for transportation or for transportation-related services to ensure that offerors become familiar with conditions under which and where the services will be performed: Familiarization with Conditions (Apr 1984) The offeror shall become familiar with all available information regarding difficulties that may be encountered and the conditions, including safety precautions, under which the work must be accomplished under the contract. The offeror shall not be relieved from assuming all responsibility for properly estimating the difficulties and the cost of performing the services required in this contract because the offeror failed to investigate the conditions or to become acquainted with all information concerning the services to be performed.
