FAR 36.521—Specifications and drawings for construction.
Plain-English Summary
FAR 36.521 tells contracting officers when to include the clause at 52.236-21, Specifications and Drawings for Construction, in construction-related solicitations and contracts. It covers three main topics: mandatory use of the clause for fixed-price construction contracts and fixed-price dismantling, demolition, or removal of improvements contracts above the simplified acquisition threshold; discretionary use of the clause for those same fixed-price contracts at or below the simplified acquisition threshold; and the required selection of Alternate I or Alternate II when the Government needs record drawings, depending on whether reproducible shop drawings are needed. In practice, this section matters because it controls how the Government and contractor will handle specifications, drawings, and record-drawing deliverables on construction projects. It helps ensure the contract clearly addresses drawing responsibilities, reduces disputes over design documents, and supports accurate as-built records for future maintenance, operations, and renovations. For contractors, it signals when the clause will govern submittals and drawing obligations; for contracting officers, it is a drafting rule that must be applied correctly based on contract type, dollar threshold, and record-drawing needs.
Key Rules
Mandatory clause above threshold
The contracting officer must insert FAR 52.236-21 in solicitations and contracts for fixed-price construction contracts and fixed-price dismantling, demolition, or removal of improvements contracts when the expected contract amount exceeds the simplified acquisition threshold.
Optional clause at or below threshold
For the same types of fixed-price construction or demolition/removal contracts at or below the simplified acquisition threshold, the contracting officer may include the clause, but is not required to do so.
Record drawings require special selection
If the Government needs record drawings, the contracting officer must use the clause with the appropriate alternate rather than the basic clause alone.
Alternate I for reproducible shop drawings
Use Alternate I when reproducible shop drawings are needed as part of the record-drawing requirement. This alternate is intended for situations where the Government wants record drawings that can be reproduced from shop drawing materials.
Alternate II when reproducible shop drawings are not needed
Use Alternate II when the Government needs record drawings but does not need reproducible shop drawings. The alternate selected should match the actual documentation format the Government expects to receive.
Responsibilities
Contracting Officer
Determine whether the contract is a fixed-price construction or demolition/removal contract, check whether the expected amount is above or at/below the simplified acquisition threshold, and insert FAR 52.236-21 accordingly. If record drawings are needed, select Alternate I or Alternate II based on whether reproducible shop drawings are required.
Contractor
Review the solicitation and contract to understand whether the Specifications and Drawings for Construction clause applies and whether an alternate has been included. If included, comply with the clause’s requirements for drawings, submittals, and any record-drawing obligations tied to the selected alternate.
Agency/Program Office
Identify early whether the project will require record drawings and whether reproducible shop drawings are necessary, so the contracting officer can choose the correct clause version. Provide the technical input needed to align the contract documents with the project’s documentation needs.
Practical Implications
This section is a drafting and administration checkpoint: if the wrong version of the clause is used, the contract may not clearly assign drawing and record-drawing responsibilities.
The simplified acquisition threshold matters because it determines whether inclusion of the clause is mandatory or discretionary for covered fixed-price construction and demolition/removal work.
When record drawings are needed, the contracting officer must think beyond the basic clause and choose the correct alternate; failing to do so can create confusion about the format and reproducibility of required drawings.
Contractors should pay close attention to whether shop drawings must be reproducible, because that affects how submittals are prepared and what deliverables may be required at closeout.
Common pitfalls include overlooking demolition/removal contracts, assuming the clause is only for traditional construction, and not coordinating technical staff input before finalizing the solicitation.
Official Regulatory Text
The contracting officer shall insert the clause at 52.236-21 , Specifications and Drawings for Construction, in solicitations and contracts when a fixed-price construction contract or a fixed-price dismantling, demolition, or removal of improvements contract is contemplated and the contract amount is expected to exceed the simplified acquisition threshold. The contracting officer may insert the clause in solicitations and contracts when a fixed-price construction or a fixed-price contract for dismantling, demolition, or removal of improvements is contemplated and the contract amount is expected to be at or below the simplified acquisition threshold. When the Government needs record drawings, the contracting officer shall- (a) Use the clause with its AlternateI, if reproducible shop drawings are needed; or (b) Use the clause with its AlternateII, if reproducible shop drawings are not needed.
