Service 03
Engineer-approved structural information translated into steel detailing models, assembly and single-part shop drawings, specified connection details, erection plans and fabrication schedules for pipe racks, platforms and industrial steelwork.
We provide structural steel detailing support for industrial facilities, pipe racks, pipe bridges, access platforms, equipment supports and associated steelwork.
The service translates approved structural design information, connection requirements and fabricator practices into a coordinated detailing model, fabrication documents, erection information and material schedules for project review and workshop use.
Depending on the assignment, a package can comprise a Tekla Structures model, general arrangement and erection information, assembly drawings, single-part drawings, member and part marks, bolt and material lists, and supported digital fabrication outputs. Detail level, approval stages, connection-design responsibility and formats are agreed before work begins.
A structural steel detailing package turns an approved structural design into the information a fabricator and an erector need. It typically contains a detailing model such as Tekla Structures, general arrangement and erection drawings, assembly drawings for each shipping piece, single-part drawings for plates and profiles, member and part marks, bolt lists and material take-offs, and NC or DSTV machine files where contracted. The detailer works from the approved structural GA and member design, the connection design or criteria with its design authority confirmed, material grades, bolting and welding requirements, and the project and fabricator shop standards. Detail level, approval stages, connection-design responsibility and file formats are agreed in writing before work starts, and every issue carries a revision record. The structural or connection designer stays responsible for engineering decisions and calculations, and the detailer's production checks do not replace the engineer's or the fabricator's own contractual reviews.
Downstream of approved structural and connection design, upstream of the fabricator's workshop. We detail what the engineer has designed; the engineer and the fabricator keep their own review and approval roles.
A model-only assignment without drawings is scoped under 3D Structural Modelling & Plant Model Support. Standalone quantities can be purchased under Material Take-Offs, BOM & Engineering Documentation.
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.
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.
Framing drawings, member sizes, engineer-specified connections, design marks, material grades, project standards and fabrication preferences reviewed; missing information raised as queries.
Agreed model geometry for steel members, bracing, beams, columns, platforms and secondary components, built with supported tools.
Specified base and end plates, gussets, stiffeners, connection plates, bolts and weld information documented from approved design instructions. Design calculations are not implied.
Members and assemblies located with grids, levels, marks and orientation, with erection plans and elevations and field connection indications.
Workshop information for each fabricated assembly: components, dimensions, fabrication positions, connections and relevant notes.
Isolated member and plate information with part identification, material, dimensions, holes, cuts and the necessary workshop details.
Erection plans, member and assembly IDs, field connections and agreed installation-location information. Erection methodology and temporary works design stay separate.
Drawing- and model-derived member, plate, bolt and material schedules with a defined measurement and revision basis.
NC / DSTV or other machine data, only after the software workflow, the fabricator's equipment requirements and present capability are validated for the package.
Approved design and fabricator feedback incorporated, models, drawings and lists kept consistent, and controlled revision records issued.
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.
Detailing follows the project-specified steel, welding and bolting standards and the approved connection design. The scope of work records the applicable editions.
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 appliedMember and connection design come from the responsible engineer. The detailing basis records who owns each before modelling starts.
Marks, numbering, title blocks, drawing presentation and bolt and weld conventions follow the fabricator's or client's agreed standards.
Material grades, welding, bolting, coating notes and tolerances as stated in the project specification and its editions.
Tekla version, drawing formats, machine-file requirements and review stages are agreed before production.
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.
Tekla Structures is the primary detailing platform. Machine data is issued only after the fabricator's equipment requirements and the software workflow are validated for the package.
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.
Model Review & Coordination
Model review, walkthrough and coordination checks against other disciplines.
The usual sequence for this service. Steps can overlap, and review comments loop back to earlier steps.
Approved design, connections and standards reviewed; queries raised.
Model conventions, marks, detail level and approval stages defined.
Members and approved connections modelled to the agreed level.
Arrangement, assembly, single-part and erection sheets prepared.
MTO, BOM and bolt lists prepared and reconciled with the model.
Geometric and document consistency checked before submission.
Engineer and fabricator comments incorporated; revisions re-issued.
Review & responsibility
Coordinated structural steel detailing helps project and fabrication teams identify interface issues, maintain member and assembly identification and minimise avoidable discrepancies between models, shop drawings and material documentation. Changes are reviewed against the agreed design basis and incorporated through controlled model and drawing revisions. Deliverables remain subject to the review and approval responsibilities assigned under the project contract.
The structural designer or connection designer remains responsible for engineering design decisions and calculations unless a separately qualified design scope is expressly contracted. A steel detailer's production checks do not remove the engineer's or fabricator's contractual reviews.
Connections are detailed from the engineer's connection design. A standalone model without drawings is scoped under 3D Structural Modelling & Plant Model Support. 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.
