Writing Useful RFIs for Steel Building Interfaces
Write steel building requests for information that locate a real conflict, identify compared revisions, and explain the dependent activity.
Define the condition and its scope
An RFI asks a bounded question that the recipient can answer within their responsibility.
Coordination connects the steel package to the rest of the building. Red iron framing, cold-formed infill, foundations, doors, roof equipment, and interior finishes can each have a different document author. A correct component can still arrive with an unresolved interface. Establish which issued drawing governs each condition, how questions reach the responsible professional, and where responses are recorded. Separate a contractor's field measurement from a designer's acceptance of that measurement, and keep both available to the people preparing fabrication or installation documents.

Gather the inputs before deciding
Write the subject around the decision required, not a general trade heading. Locate the question by grid, elevation, opening identifier, or detail reference and list the documents that disagree. Describe the observed condition separately from a suggested option. State what work depends on the answer and the needed response date without presenting urgency as authority to proceed. Avoid combining unrelated conflicts in one request; separate questions let reviewers assign appropriate responsibility and close each answer clearly.
- Conflict location and grid
- Drawing revisions compared
- Required technical decision
- Dependent work date

Set observable handoff deliverables
A vague question such as 'please advise' conceals the specific decision needed.
| Input | Evidence to keep with it | Review status |
|---|---|---|
| Conflict location and grid | Located marked-up detail | Identify reviewer and written decision |
| Drawing revisions compared | Compared document revision list | Identify reviewer and written decision |
| Required technical decision | Written decision and resulting revision | Identify reviewer and written decision |
Sequence review and release
Check the current documents before submitting the RFI so the question does not reproduce an already issued answer. Send the bounded question through the project channel, record receipt, and track it against the dependent activity. When answered, identify whether another discipline must concur or a revised drawing is required. Notify the supplier and crew using the affected instruction. If the response remains ambiguous, ask a focused follow-up rather than selecting the interpretation that is easiest to construct.
- Locate conflict location and grid in the current record.
- Compare drawing revisions compared with the table's evidence.
- Document the decision: Close the question only after dependent documents reflect the answer.
Worked project coordination example
A wall detail and door schedule show different jamb positions. The RFI marks both references, gives the measured location, and asks which coordinated position governs before wall framing begins.
Apply the stated release decision to the case: Close the question only after dependent documents reflect the answer. The responsible team determines acceptance for the actual project and records any condition that still requires resolution.
Keep a closeout record another team can use
Keep the RFI number, located attachments, response, reviewer identity, and resulting document revision in one traceable record. Record distribution to the packages that rely on the answer. Distinguish a response that confirms existing requirements from one that changes them and needs separate scope authorization. Field leaders should use the accepted instruction, not an isolated screenshot of the answer. Close the request when its downstream documents and relevant installation decisions are coordinated, while preserving any remaining contractual issue separately.
For this issue, include written decision and resulting revision in the handoff. If review remains pending, identify the dependent work and its owner; do not present the record as a completed technical acceptance.
Common questions
Should an RFI propose an unreviewed field fix?
Describe the issue; label any proposal clearly for responsible professional evaluation.
How should conflict location and grid be documented?
Close the question only after dependent documents reflect the answer. Retain located marked-up detail and check that the decision reached the team performing the dependent work.

Prepare a supply inquiry
- Record the project drawing or detail and the specified product, profile, or system.
- List the complete configuration, physical units, quantities, and cuts per piece.
- Request current manufacturer documents; confirm compatibility, price, and availability before ordering.
- Obtain the responsible professional's review for loads, code requirements, or installation.
