Service 02
Tekla steel models and suitable plant structural model updates developed from agreed design information in supported software environments, with coordination views, exchange files and documentation outputs where included in scope.
We support structural steel and industrial project teams with 3D model development, updates, coordination and model-based documentation.
Work may involve a Tekla Structures model developed from approved engineering drawings, a modification to an existing steel model, or structural modelling support within a compatible plant design environment.
Model purpose and level of development are confirmed at the outset: a coordination model, a detailed steel model, a fabrication-oriented model and an existing-plant update need different inputs, attributes and outputs. Coordinates, member identification, modelling conventions, software versions and native or exchange formats are agreed before production. Drawing packages and independent engineering verification are separate deliverables, not implied by a model.
A 3D structural modelling package should state the model's purpose and level of development before production starts, because a coordination model, a detailed steel model, a fabrication-oriented model and an existing-plant update need different inputs and outputs. The specification covers the model origin and coordinate basis, grids, member identification and naming rules, software version, templates and libraries, and the native and exchange formats to be delivered, such as IFC. Inputs are approved structural layouts and steel schedules, connection requirements where components are modelled, discipline reference models and client review mark-ups. Typical outputs are the model at the agreed detail level, coordinated model views, native or IFC exchange files, revision notes, an issue and coordination register, and model-derived quantity reports where included. Drawing packages are a separate deliverable, not implied by a model, and structural analysis, design adequacy and clash-resolution authority remain with the parties defined in the contract.
Can be scoped on its own as a model-only package, or as the first stage of a steel detailing package. In both cases the model is built from approved design information, to a purpose and level of information agreed at the start.
Where shop and erection drawings are needed, they are scoped under Structural Steel Detailing & Fabrication Documentation, and the detailing model is delivered as part of that package rather than sold twice.
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.
PDMS-related support and piping layout or isometric drawing support are offered only after the available software, compatible files, personnel expertise and project requirements are confirmed. Complete piping design, piping stress analysis, process engineering and mechanical design are not implied.
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.
Client origins, levels, reference models, units, libraries and model conventions established, together with the agreed model purpose and level of information.
Framing members, beams, columns, bracing, platforms, pipe-support structures and agreed secondary steel modelled from the approved design.
Plates, stiffeners, specified connection geometry and associated steel components to the agreed detail level. Connection design remains a separate responsibility.
Structural models and references developed or updated in supported plant environments, such as PDS with FrameWorks Plus and MicroStation, where access, licences and file compatibility are confirmed. This is not full multidiscipline plant design.
Approved revision mark-ups, steel replacement and modification information applied to existing plant and structural models where a compatible update is feasible.
Relevant geometry, discipline interfaces and identified clashes checked, with comments and queries issued. Resolution of other disciplines' clashes stays with their owners.
Agreed model views, documentation and model-derived quantities. Fabrication and shop drawing packages sit in Structural Steel Detailing unless explicitly included.
Accepted native versions, IFC or other supported interchange files, reports and revision notes as contracted, with formats and software confirmed before acceptance.
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.
Models follow the client's modelling rules, naming and level of detail. ISO 19650 information management is followed where the project adopts it.
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 appliedWhether the model serves coordination, detailing, fabrication or an existing-plant update is agreed first, with the attributes each purpose needs.
Origins, units, naming, numbering, profile and material catalogues and modelling conventions follow the client's rules.
Piping, equipment and electrical reference models are used as supplied. Ownership of clash resolution stays as defined in the contract.
Platform, version, licences and the right to work on client model data are confirmed before any update or exchange.
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.
Plant environments listed here come from senior personnel's prior project experience; historical PDS or PDMS competence does not establish a present licence. Access, licence and version for a new package are 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.

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.
Existing files, versions, licences and data rights checked.
Purpose, level of information, origin and coordinates agreed.
Primary and secondary members modelled from approved inputs.
Plates, bolts and specified components added to the agreed level.
Geometry reviewed against other disciplines; queries and clashes raised.
Approved changes incorporated and tracked against revisions.
Native, IFC or other agreed models and reports issued.
Review & responsibility
Models are reviewed for geometry, member identification and agreement with the approved inputs before each issue, and selected interfaces are checked against the reference models supplied. Comments and clashes are logged and closed out through controlled model revisions. A correctly formed model is not proof of structural adequacy, code compliance or clash-free construction.
These are modelling and model-documentation services from approved engineering inputs. Structural analysis, design adequacy, design approval and the authority to resolve other disciplines' clashes remain with the parties defined in the contract. Tekla and other tools are used only where legitimately available and supported.
PDS or PDMS experience does not imply full plant design services. Fabrication and erection drawings extracted from a model are scoped under Structural Steel Detailing & Fabrication Documentation. 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.

No. A model-only package can be scoped on its own. Steel shop and erection documentation is handled through Structural Steel Detailing & Fabrication Documentation.
We first examine the available files, project and version compatibility, required licences, data integrity and the scope of authorised changes, then confirm whether a direct model update is feasible.
Selected geometric interfaces can be reviewed against the reference models available. Clash ownership, resolution authority and final acceptance remain as defined in the contract.
Tekla Structures, PDS with FrameWorks Plus and MicroStation, with exposure to PDMS, and Navisworks for review. Availability of a specific environment and version is confirmed for each package.
Share your existing model or approved structural drawings, required modelling platform and version, reference coordinates and expected outputs to discuss a 3D modelling package.
