BIM Outsourcing in Kuwait: Modelling, Coordination and Engineering Design Support

BIM outsourcing in Kuwait usually means one of two things: a team that builds and maintains the models for an MEP or ELV scope, or a team that checks and coordinates models produced by others. The two are different jobs with different responsibilities, and mixing them up is a common source of disputes on coordinated projects.

BIM modelling and documentation workflows

A typical workflow for a building services or ELV scope runs in four steps:

1. Set up. Agree the model scope, the software and version, the coordinate system, the level and grid structure, and the shared file location. Link the architectural and structural models at a fixed revision.
2. Model. Build the systems to the agreed level of detail, with the parameters the information exchange requires.
3. Coordinate. Run clash and coordination checks against the other disciplines, log the clashes, and assign them to owners.
4. Issue. Produce the drawings, schedules and model exchange files for each stage, with revision control.

Each step should have a named owner. Where the BIM execution plan sets the requirements, follow it. Where it does not exist, record your assumptions and ask for it to be issued.

Revit MEP modelling scope and model development requirements

A modelling scope should state, for each system, the elements to be modelled, the level of development expected at each stage, and the information to be carried in each element. For ELV and ICT systems, typical elements include containment, cable tray and conduit runs, racks, device families, risers and equipment rooms. The level of detail for a device family differs from that for a riser, so define them separately.

Model development requirements also set the coordinate and level basis. Agree the project base point, shared coordinates and levels with the architectural team before any services model is started. Changing these later moves every element.

Model coordination and clash identification

Clash identification compares elements from different models and reports where they overlap or fail a clearance rule. Not every clash is a design error. Some are tolerance issues, some are placeholders, and some are duplicates. Agree the clash test rules, the tolerance and the report format at the start, and review the rules when the model structure changes.

Keep clash reports short and actionable: the two elements, the location, the discipline responsible for the fix, and a status. A report with 800 open clashes and no owners is not a coordination tool.

Information exchange and naming conventions

Naming conventions make models usable by other teams. Agree file names, view names, family names and parameter names before modelling begins. Where the project uses ISO 19650 terminology, check that the information requirements and the exchange format match the employer's information requirements. The standard applies to the project as set by the contract; confirm its status with the client.

Specify the exchange format for each stage, such as native model files, IFC or PDF drawings, and state which format is the authoritative record. A drawing set that differs from the model is a common problem at handover.

Coordination with project BIM execution requirements

The BIM execution plan, or the equivalent document in the contract, is the reference for the work. It should cover the model uses, the level of detail, the collaboration process, the approval routine and the responsibility matrix. A BIM outsourcing scope that does not refer to it is likely to be incomplete.

Modelling support versus engineering design responsibility

Modelling support produces a model to a design basis set by the engineer of record. Engineering design responsibility covers the design decisions, calculations and approvals. A model can be geometrically correct and still carry the wrong design decision. The appointment should say which party owns each decision, and which party checks the model output against the design basis.

Deliverables, revision control and quality checks

Typical deliverables include the coordinated model at each stage, clash reports with status, drawings and schedules generated from the model, and an issue log. Quality checks should include a model audit against the naming and level-of-detail requirements, a check that drawings match the model, and a review of open clashes before each issue. Revision control should record the model version and the drawing revision together, so the two can be traced to each other.

Common mistakes and how to avoid them

• Starting the model before the coordinate basis is agreed. Agree the base point and levels first.
• Linking outdated architectural models. Record the revision of every linked model.
• Clash checks run without rules. Agree tolerances and test sets before the first run.
• Drawings issued from a model that has not been checked. Run the model audit before any issue.
• Treating modelling support as design sign-off. State the responsibility split in the appointment.

Guidance for consultants, developers and contractors

Consultants should issue a clear BIM scope and the level of detail for each system before appointing support. Developers should include the BIM execution requirements in the tender documents. Contractors should check that the model they receive is the one the design team approved, and should ask for the clash log and the revision record with each issue.

Conclusion

BIM outsourcing works when the modelling scope, the coordinate basis, the clash rules and the responsibility split are settled in writing. Without those, models multiply and clashes stay open. With them, the model becomes a reliable record that every discipline can use.

Frequently asked questions

What is the difference between BIM coordination and BIM modelling?

Modelling creates the elements. Coordination checks the models against each other and tracks the clashes to resolution. Some projects separate these roles and some combine them.

Does a BIM model replace drawings?

Not unless the contract says so. Drawings are often still the issued record, and the drawings must match the model at each issue.

What should I ask a BIM support provider?

Ask which software and version they use, how they run clash checks, how they name and audit files, and how the responsibility for design decisions is split.
