How to write a structural steel ITP

Set the shop boundary before listing checks

Identify which organisation details, supplies, processes, welds, examines, coats, packs and dispatches the steel. A distributor, processor, fabricator, coating subcontractor and erector may each hold a different piece of the evidence. Name the lot and interfaces so one party's report remains linked to the member after it changes hands.

Write one checkable row per event

1. Use a specific fabrication activity and identify the member, joint or lot it applies to.
2. Describe what the fabricator compares, inspects, measures or collects. Name the actual drawing/detail or approved procedure in the project version.
3. State a condition that can be observed from the cited source. If the source contains a value, copy its exact value and units into the project plan; this baseline intentionally supplies none.
4. Take frequency, witness rights, notice, reviewer and release conditions from the actual contract. Label proposed internal readiness separately.
5. Name the record and the fields that will connect the result to the member and its source evidence. Leave actual inspection results, dates and signatures blank.

Nine fields from a fictional shop requirement to a plan row

Fictional teaching example only. Drawing ST-F01 Rev B, member mark B17, and specification SP-F01 are invented identifiers. They do not refer to a real project or required standard.

This example shows how to make the evidence trail readable without filling in missing technical decisions. A real project row must replace the fictional identifiers with controlled approved documents.

1. ID and stage

FBR-05 / FBR-06 · Fit-up and welding for member B17, joint shown on the approved weld map.

2. Inspection

Verify joint preparation against the approved procedure before welding; keep the completed weld tied to member B17 and its joint mark.

3. Method

Locate the joint on the controlled weld map, compare the observed preparation features with the approved procedure, and record the joint/member identifiers and observed evidence. After welding, carry the same identifiers into the inspection record.

4. Acceptance criterion

For this fictional excerpt, the joint preparation matches the cited approved procedure and the completed inspection record identifies B17 and the mapped joint. A real weld acceptance condition must come from the project's specified welding and inspection criteria; this example does not supply one.

5. Reference

Fictional SP-F01 Rev A, fabrication interface note; fictional ST-F01 Rev B, member B17; fictional approved weld map WM-F01 and procedure WP-F01 [replace with actual revisions and locators].

6. Frequency or trigger

Before welding the identified joint. The example does not define a wider sampling or inspection rate; use the project requirement.

7. Responsibility

[Enter the assigned fabricator role and any required inspector/reviewer.] The source excerpt names no person, qualification, client witness or design authority.

8. Control or release arrangement

[Enter the actual project inspection point, notice, evidence and release authority if one is specified.] The fictional note does not create an external Hold Point.

9. Record

Joint fit-up and weld record: member B17; joint/weld-map locator; drawing and procedure revisions; observed preparation; production record reference; inspection/NDT report reference only where specified; repair/reinspection or written disposition reference. Actual observations, measurements, dates and signatures stay blank until performed.

Keep the piece-mark trail continuous

A certificate is useful only when the project-required link between it and the physical steel remains clear. A practical trail starts with supplier identification, passes through the incoming register, and survives cutting, processing, assembly, coating and packing. When a mark is transferred, the record should identify the original source and the new member marks. For a weld, add a joint ID and weld-map locator; for subcontract coating, carry the piece/lot marks onto the report; for dispatch, connect those marks to the packing list and dossier index.

On site, the receiving record should be able to resolve the same member mark back to the fabrication dossier. The connection is complete when a reviewer can follow a specific installed member or joint to the drawing, material evidence, process records, inspection report and any disposition without guessing which file belongs to it.

Do not borrow a transport specification for a building

TMR MRTS78 is a Queensland transport and infrastructure contract specification. It has detailed requirements and formal Hold/Witness points for its own work, but those provisions do not become defaults for a commercial building simply because the project uses steel. Confirm the documents and edition incorporated by the actual contract. ASI process and traceability guidance helps identify useful questions; it does not provide this project's numeric weld, NDT, tolerance or coating criteria.

Use the matching fabrication package

Start with the structural steel ITP baseline, then select the steel fabrication ITP template for the shop sequence. The related material receiving record, weld inspection record and bolting record cover separate field evidence where applicable. They remain blank records, not pre-completed inspections.

Separate the site package from fabrication

An erection ITP starts with a workfront, member list and controlled erection information. It records how the site team will identify and inspect the delivered steel, check interfaces and retain evidence for each connection and handover. The fabricator’s dossier supports this work but does not replace site checks. Conversely, the site plan does not redo every shop inspection.

Trace one fictional connection through site records

Fictional teaching example only. Grid C/4, column mark C04, beam mark B12, connection mark CN-C04-B12 and drawing ST-E01 Rev C are invented identifiers. No actual member, installation, survey result or approval is described.

1. Receive the pieces. Record the delivery/packing reference and verify that marks C04 and B12 connect to the listed fabrication records. Note actual visible damage or missing evidence; keep original supplier and fabrication documents.
2. Check the interface. Before placement, identify support/anchor evidence for grid C/4 and cite the project drawing and survey record. Route a discrepancy to the assigned designer or project authority.
3. Use approved erection information. Identify the controlled sequence and temporary stability document applicable to the operation. This is a document and role check; the ITP does not calculate or approve stability or lifting.
4. Record the connection. Link CN-C04-B12 to both member marks, the drawing detail and the installed fastener lot/procedure or site weld evidence actually required by the project.
5. Close with actual geometry and disposition. Record the survey report and measured observations against the source criteria. Link any deviation, written direction, recheck and handover status without pre-filling a result.

Use the erection baseline in a controlled way

The dedicated package steel erection ITP template uses rows ERE-01–ERE-08: workfront documents, delivery receipt, base/anchor interface, approved readiness documents, member placement, bolted and conditional site-welded connections, then geometry and handover. These are candidate planning activities. The actual construction sequence, values, frequency, assigned roles and external control points must come from the project documents.

Use identifiers consistently across the plan, receiving record, survey report, bolt or weld record, NCR/disposition and dossier. If a connection changes, record the approved revision and link the actual installed condition to it. If the evidence is incomplete, state exactly what is missing and who must decide; do not mark a connection accepted merely because the member is standing in place.

Geometry, temporary works and hold points need project sources

The ASI describes erection as placing and connecting components and aligning the frame against project expectations. That description does not provide a tolerance. Copy survey criteria from the adopted project source and identify the exact grid/member/measurement point. Temporary stability and lift controls come from approved engineering documents and the applicable safety process. Contractual Hold/Witness points, notice periods and release permissions also come from the contract; none should be inferred from a template label.

Queensland TMR MRTS78 includes its own infrastructure-specific controls. Those clauses and role arrangements apply only where the relevant TMR contract adopts the applicable current specification. Do not use them to fill a missing building requirement.

Related blank records

Use the steel material receiving record for member identity and delivery exceptions, the bolted connection record for project-required installation evidence, and the steel erection inspection record for location, restraint, geometry and handover observations. Site welding, if in scope, also needs its own weld/map inspection trail. Keep the original survey, test and fabrication reports as evidence; a summary checklist only indexes them.
