Quick answer

Navisworks Model Review & Clash Detection covers federating multi-discipline models and running clash detection and review sessions. Done properly, it follows ISO 128, ASME Y14.5, Client CAD standards and produces 2d detail drawings that a fabricator or reviewer can use without rework. Structural Engineering Services delivers navisworks model review & clash detection to clients in 40+ countries with a senior-engineer review on every package.

What navisworks model review & clash detection actually includes

Navisworks Model Review & Clash Detection is the discipline of federating multi-discipline models and running clash detection and review sessions. In practice a complete scope covers the full chain from design inputs to construction-ready output, not just a single drawing or calculation.

A typical navisworks model review & clash detection package from our team includes: 2d detail drawings, bim / 3d models, clash detection reports, as-built drawings. Each deliverable is produced on licensed AutoCAD, Revit, Inventor, Navisworks, BricsCAD and passes an internal checker review before it reaches you.

How the work is delivered, step by step

Most engagements follow the same five-stage flow, whether the package is a single drawing or a multi-month frame agreement.

  • Share inputs — design drawings, specifications and the project schedule.
  • Free quote in 24 hours — fixed lump-sum, per-tonne, per-drawing or hourly.
  • Model & engineer — built on AutoCAD to ISO 128.
  • Review & approve — internal check, then your comments closed fast.
  • Issue for construction — 2d detail drawings and bim / 3d models issued with revision control.

Which codes and standards govern navisworks model review & clash detection

The governing standard depends on where your project is built. Our teams work daily to ISO 128, ASME Y14.5, Client CAD standards and to client specifications such as Shell DEPs and major operator standards.

Getting the code basis agreed at kick-off is the single most effective way to avoid late-stage rework — it fixes load combinations, material grades, tolerances and documentation format before modeling starts.

When you need it — and when you don't

You need professional navisworks model review & clash detection whenever the output feeds fabrication, regulatory review or a design-responsibility handover. Early concept sketches and feasibility studies can be lighter, but anything issued for construction should carry a checked, code-referenced package.

If you are unsure which level of detail your project needs, send us your inputs — a senior engineer will scope it honestly, even if that means telling you a smaller package will do.

How it runs

A navisworks model review & clash detection package, stage by stage

Most engagements follow the same five stages, whether the scope is one drawing or a multi-year frame agreement. Durations below are typical for a small-to-medium package.

Phased submissions let fabrication start on the first release while later stages are still in production — agree the split at kick-off.

  1. 01

    Inputs & kick-off

    Day 0–1

    Design drawings, specifications and the schedule are logged in a document register. The code basis (ISO 128) and the deliverable list are agreed in writing.

  2. 02

    Fixed-price proposal

    Within 24 hours

    A senior engineer scopes the work and returns a lump-sum, per-unit or rate-based proposal with the inclusions stated line by line.

  3. 03

    Model & engineer

    Days 2–10

    The work is built on licensed AutoCAD to ISO 128, with interim progress models shared so misunderstandings surface early rather than at issue.

  4. 04

    Check & client review

    Days 8–12

    An independent checker reviews the package against the compliance matrix, then your comments are closed and recorded against the 2d detail drawings.

  5. 05

    Issue for construction

    Days 12–15

    2d detail drawings and bim / 3d models are transmitted under formal revision control, with native files and the checker's record attached.
