4D & 5D BIM Dubai - Sequence the build and cost it from the same model

BIM Services Dubai links the 3D model to your construction schedule for 4D sequencing, and extracts quantities for 5D cost takeoff.

  • Schedule-linked sequencing
  • Model-based quantity takeoff
  • Updates as design changes

4D and 5D: two linked BIM services

  • 4D sequencing

    The model is linked to your construction schedule to simulate phasing and spot sequencing conflicts before they happen on site.

  • 5D quantity takeoff

    Quantities are extracted directly from the model, so cost estimates track design changes instead of lagging behind them.

  • Built for large, phased sites

    Especially useful for master-plan phases, logistics facilities and any site where phasing against live operations matters.

Our process

How 4D and 5D BIM link your model to schedule and cost

4D BIM ties model elements to your construction schedule so sequencing can be reviewed and clashes in timing - not just geometry - get caught before they hit site. 5D BIM extracts quantities directly from the model for takeoff, so a design change updates the quantities automatically instead of requiring a manual re-measure.

Who 4D and 5D BIM helps most

Contractors managing phased handover or tight cost control get the most from 4D/5D - sequencing catches timing conflicts before they hit site, and quantities update automatically as the design changes instead of needing a manual re-measure.

Where 4D and 5D BIM earns its cost

  • Master-plan phased communities

    Coordinate later construction phases against infrastructure already built.

  • Logistics and industrial sites

    Sequence large-footprint construction against live operations nearby.

  • Cost-sensitive projects

    Quantities tied to the model reduce the gap between design and budget.

4D & 5D BIM questions

Do I need 4D and 5D together, or can I get just one?

They're offered separately. 4D sequencing needs your construction schedule; 5D takeoff needs a model at a defined LOD. Many projects start with one and add the other later.

What software do you use for sequencing?

Navisworks TimeLiner for 4D sequence simulation, linked to the coordinated model.

Does 5D takeoff replace a quantity surveyor?

No, it gives the QS model-derived quantities to work from, which is faster and more accurate than manual takeoff from drawings.
