Who we work with

Four kinds of client buy navisworks model review & clash detection from us

The scope looks similar on paper. What each buyer actually needs from it does not — so the engagement is shaped around it.

Steel & equipment fabricators

Shop loaded, schedule fixed, no spare detailing capacity in house.

What you get

Clean, standards-compliant sheets that match the way your shop reads drawings, produced faster than hiring for the peak.

EPC & engineering contractors

Multi-discipline scope, moving client revisions, hard contractual dates.

What you get

Elastic drafting capacity that absorbs document-production peaks without diluting your in-house engineering team.

Consultants & design offices

Work won beyond current capacity, delivered under your own stamp.

What you get

A white-label drafting desk working inside your CAD standard, so issued drawings look like your own office produced them.

Owners & operators

Plant modifications, life extension and independent verification.

What you get

Legacy drawings and as-builts brought back under control in a single, consistent and genuinely usable document set.

How we deliver

From your drawings to issued-for-construction, in five steps

The same engagement runs every navisworks model review & clash detection project, whether it is a single package or a multi-year frame agreement — so you always know what happens next and who owns it.

  1. 01

    Share your inputs

    Day 0 · NDA on request

    Send what you already have — markups, sketches, scans, legacy DWGs or point-cloud data, plus your CAD standard, layer convention, title block and sheet-numbering rules. Incomplete inputs are fine; we list the gaps rather than guess at them.

  2. 02

    Fixed quote in 24 hours

    Within 24 hours

    A senior engineer reviews the package and returns a priced proposal with scope, assumptions, exclusions and a milestone plan for your navisworks model review & clash detection. No obligation, no placeholder pricing.

  3. 03

    Model & engineer on AutoCAD

    Licensed AutoCAD + Revit

    Work is produced directly in your CAD environment to your layer, lineweight and annotation standard — models federated and clash-checked in Navisworks where several disciplines meet, so the drawings you receive are already coordinated.

  4. 04

    Two-stage senior check

    Checker → senior approval

    Nothing leaves our office on one pair of eyes. An independent checker verifies the technical content, then a senior engineer approves it against ISO 128 / ASME Y14.5 and your project specification.

  5. 05

    Issue, revise, close out

    6 deliverable types

    Final issue is a tidy, standards-compliant set: native files plus PDF and DWG, clash and review reports where modelling is in scope, and an as-built update once site changes are captured. Comments are closed within two revision cycles, and RFIs raised during fabrication or construction are answered inside 48 hours.

Exactly what a navisworks model review & clash detection package covers

No vague scopes and no surprise variations. This is what sits inside the base price, what you can bolt on, and what we need from you to start.

Engagement & pricing

Four ways to buy the same engineering

Pick the commercial model that matches how your navisworks model review & clash detection work arrives — one-off package, measurable units, or continuous capacity.

Fixed lump sum

one price, whole scope

Best for

Defined navisworks model review & clash detection packages where the inputs are frozen and you need budget certainty before you commit.

Scope, assumptions and exclusions written into the proposal, so variations are visible rather than invoiced quietly.

Typical turnaroundQuoted in 24 hours, milestones agreed at kick-off

Per-sheet rate

Most used

per drawing sheet

Best for

Drafting, conversion and redraw work where sheets are the natural unit of scope.

Banded by sheet complexity, agreed from a sample before work starts.

Typical turnaround15–30 sheets per drafter per week depending on complexity

Hourly rate

per engineer hour

Best for

Markups, model reviews and open-ended support where scope cannot be counted up front.

Transparent timesheets with a not-to-exceed cap you set.

Typical turnaroundSame-day start, weekly timesheet and progress report

Dedicated engineer

per engineer month

Best for

Continuous workload, frame agreements and clients who want a named engineer who learns their standards and stays on the account.

Your engineer works on licensed AutoCAD inside your workflow, reporting to your lead as an extension of your team.

Typical turnaroundEngineer allocated within 5 working days, with overlap hours in your timezone

Quality assurance

Two senior checks before anything reaches you

Every navisworks model review & clash detection deliverable is checked by an engineer who did not produce it, then approved by a senior engineer who signs it by name.

Licensed software — no cracked tools, ever
  1. Stage 1

    Independent discipline check

    Checked by an engineer who did not produce the work

    The checker rebuilds the critical numbers rather than reading along with them, marking up every sheet of the navisworks model review & clash detection package against the inputs.

    • Every dimension, note and annotation cross-checked against the source markup or model
    • CAD standard compliance: layers, lineweights, text styles, blocks and title-block data
    • Sheet numbering, references, revision clouds and drawing register kept consistent
    • Model integrity — origin, shared coordinates, levels and grids verified before issue
  2. Stage 2

    Senior engineer approval

    Approved by name against ISO 128, ASME Y14.5, Client CAD standards

    The approving engineer looks past compliance at whether the solution is buildable, economical and right for how the asset will actually be used.

    • Drawing readability and completeness reviewed as a constructor would read it
    • Discipline coordination and clash status confirmed against the latest federated model
    • Output formats, file naming and transmittal contents checked against your document control
    • Package approved by a senior engineer before anything is released to you

    Only then is the package released — with the checker and approver recorded against the revision.
