Service 06
Structural steel quantities, bills of materials, member and bolt schedules, reinforcement quantities and revision-controlled drawing records, reconciled with the agreed source revision and measurement basis.
We prepare structural quantity information and supporting drawing documentation for steel, concrete and reinforcement packages.
Depending on the agreed source and measurement basis, assignments may include steel material take-offs, member, profile and plate lists, bolt schedules, bills of materials, reinforcement schedules and model-derived quantity reports. We also support drawing registers, review-comment incorporation, revision records and native and PDF package preparation.
For quantities to be useful, the governing drawing or model revision, units, inclusions, exclusions and treatment of changes must be clear. Production-level drawing and model checks support consistency within the agreed scope, but they are not independent structural design verification or commercial quantity certification.
A structural material take-off is reliable when its source, basis and limits are stated with the numbers. Each MTO should name the governing drawing or model revision it was taken from, the units and measurement basis, what is included and excluded, and how later changes will be reflected. Typical outputs are steel MTOs with member, profile and plate lists, bolt schedules, bills of materials where the source data allows, concrete quantities and reinforcement schedules, together with drawing registers, revision logs, comment logs and native and PDF issue packages. Inputs are the approved drawing or model issue, the agreed quantity basis, material grades and unit conventions, and the client's numbering, review and transmittal requirements. Quantities taken from an early or superseded revision are the most common source of error, so each report is tied to an issue. Production checks support consistency, but procurement quantities, commercial certification and engineering verification stay with the client's responsible parties.
Available standalone, or as embedded deliverables within other services when contracted. Every quantity and register depends on an issued source revision, so the source and measurement basis are agreed before extraction.
Bar bending schedules originate in Reinforced Concrete & Rebar Detailing; this service can compile and reconcile them for procurement. The company-wide checking process is described on the Quality & Delivery page.
Discuss Your ScopeThe work that can be commissioned under this service. Any item can be scoped on its own or as part of a package; deliverables are agreed in writing for each project.
These are production-level checks and document-control services; they do not replace independent engineering verification, formal design approval or professional certification.
The work within this service, in the order it is usually produced. Any part can be scoped on its own; the deliverables for each package are agreed in writing.
Issued drawings or models, units, measurement method, exclusions and the required report structure agreed first.
Lengths, counts, sectional weights where defined, and grade and member identification from the source information.
Drawing- or model-derived plate, bracket, bolt and connection material schedules where the source information is adequate.
Assembly- and member-based material reports with consistent marks, units and source revision.
Measurable concrete volumes and reinforcement and BBS-related quantity schedules based on defined input revisions.
Reports compared with the drawings and updated after approved changes, recording the basis and superseded versions.
Document IDs, titles, issue dates, revisions, purpose of issue and agreed status codes.
Client template conformity, naming, annotation, title blocks and references.
Authorised changes incorporated with a checkable revision history.
Agreed native and PDF files, registers, lists and technical documentation.
Sheets, references, dimensions and title-block information checked. This is not independent engineering approval.
Drawings compared with the model revision they were extracted from.
Member and list quantities reconciled to source; approved comments confirmed closed.
Package contents, revisions and transmittals verified before issue.
Structures this service regularly covers on energy and industrial projects. These are applications, not stages of the work.
What we work from
Each input is logged with its revision and status before production starts.
What you receive
Actual deliverables, formats and assumptions are negotiated and confirmed in the scope of work for each package.
Quantities follow the project's measurement rules; registers and transmittals follow the client's document control procedure.
The scope of work records the applicable standards and editions for each package. A reference to a standard does not imply design verification or certification.
How standards are appliedUnits, measurement method, inclusions, exclusions and rounding are agreed before extraction and stated on every schedule.
Each schedule names the drawing or model revision it was taken from; superseded versions are recorded, not overwritten.
Numbering, status codes, purpose of issue, review cycles and transmittals follow the client's document control procedure.
Report layout, spreadsheet structure and native / PDF handover follow the agreed format.
Examples a project may specify
Illustrative only, not a fixed or exhaustive list. The governing documents and editions are those named in your contract and project specification.
Model-based quantities depend on access to the source model and version, confirmed during scope review.
Software listed reflects the senior team's project experience. Supported platforms, versions and file formats for a new package are confirmed during scope review.
File formats & workflowSteel Modelling & Detailing
3D structural steel models, general arrangement, shop and fabrication drawings, and model-derived MTO.
2D Drawing Production
Arrangement, detail, RCC and as-built drawings, and revision incorporation on existing drawing sets.
The usual sequence for this service. Steps can overlap, and review comments loop back to earlier steps.
Measurement rules, report structure and register format agreed.
Governing drawing or model revision confirmed.
Quantities and documentation prepared from the source.
Quantities reconciled against the model and drawings.
Exclusions and assumptions annotated on the schedule.
Schedules and records issued with their source revision.
Re-issued after approved revisions, superseded versions kept.
Review & responsibility
Schedules are reconciled against the drawings or model they were taken from before issue, and comment logs track each review comment to closure. Where production checks are contracted, the checklist used and its findings are recorded with the package. No independent quantity-surveyor or commercial certification is implied.
Quantities and documentation are prepared from the client's issued sources and the agreed measurement basis. Procurement quantities, commercial certification and engineering verification remain with the client's responsible parties.
Production checking of every package is described on the Quality & Delivery page. Bar bending schedules originate in Reinforced Concrete & Rebar Detailing; this service can compile and reconcile them for procurement. Work outside these limits can be discussed as a custom scope.
Excerpts from drawings produced by our senior team during previous professional engagements. They are confidential, so they are reduced, watermarked and shown without title blocks. Full drawings are for clients only.

Straight answers on how this service works. Scopes outside what is described here are reviewed case by case; we confirm we have the right competence before quoting.
Ask about your scopeEither can be assessed. The method and accuracy depend on how complete the source is, which is reviewed before the basis is agreed.
No. No independent quantity-surveyor or commercial certification is implied; quantities are reported against their stated source and basis.
Yes, where the scope and the document-control interfaces are agreed, including revision status, transmittals and native / PDF handover.
We can carry out production-level documentation checks: completeness, references, model-to-drawing consistency and quantity reconciliation. Formal independent engineering verification is not part of this service.
Share your drawing or model package, current revision, required material categories and reporting format to request structural MTO, BOM or documentation support.
