Test it in the model, before you build it on site.

Virtual design and construction: 4D sequencing, 5D cost integration and clash coordination tied to one federated model. Programme conflicts and cost surprises surface in the model, not on site.

Programme risk shows up at the model, or at the crane

Rework and clashes on site

Conflicts that should have surfaced in coordination only show up when the steel hits the slab. Each one becomes a variation order, a programme delay and a contested cost.

Programme blind spots

The schedule lives in P6, the model lives in Revit, and nobody walks the sequence before the crane arrives. Logistics conflicts and access issues only get caught the day the work fails to start.

Cost surprises

Variations land as contested positions instead of measured deltas. Cash flow forecasts trail actual progress. The cost report tells you what already happened, not what's coming next month.

Three capabilities. One coordinated model

4D, 5D and ESG run on the same model the project team already trusts, the one we clash-coordinate on a regular cycle and sign off in the ICE coordination meeting. No second source of truth, no duplicate measure, no separate report living outside the federation.

  1. Construction sequencing, simulated.

    4D linkage of the coordinated model with the live programme. Sequencing conflicts, logistics clashes and crane-access issues surface in the model, weeks before they hit site as variation orders.

    • Construction sequence simulation
    • Logistics & access planning
    • Look-ahead vs as-built tracking
    • Stage-gate reviews tied to programme

  2. Cost loaded onto the model, not the spreadsheet.

    5D integration links the schedule to live cost data. Variations are tracked as quantity deltas, not contested positions. The cost report tracks against the programme, not behind it.

    • Schedule-linked cost reporting
    • Variation tracking from model deltas
    • Cash-flow forecasting
    • Tender package quantity comparison

  3. Embodied carbon, before pour.

    Carbon, energy, water and waste metrics computed from the coordinated model. Material substitution decisions made in design, not retrospectively reported in handover.

How VDC delivery actually runs

  • A dedicated VDC lead owns your programme

    Onsite, accountable, one name on the contract. Walks the sequence with the project team, available in your meetings, your time zone, your site walks.

  • A 260-person studio runs the simulations

    4D sequencing, 5D cost integration and ESG analysis run by a scaled production team. You pay for capacity against the programme, not for a permanent bench.

  • ISO 19650 is baked in, not bolted on

    Author-Checker-Approver on every sequence and cost run. The VDC outputs sit inside the same governed federation as the BIM Delivery model.

Common questions about VDC

BIM is the coordinated model: the geometry and the information every discipline works from. Virtual design and construction is what you do with that model before site, simulating how the building gets built. On a VDC engagement we add 4D sequencing, 5D cost integration and clash coordination on top of the same federated model, so the programme and the budget are tested in the model, not discovered on site.

4D links the coordinated model to the construction programme, so you can play the sequence forward and catch logistics, access and crane conflicts weeks before they reach site. 5D links that same sequence to cost, so variations read as measured quantity deltas against the programme rather than contested positions after the fact. Standalone quantity takeoff for the bill of quantities is a separate service, our model-based quantity takeoff; on VDC the 5D layer is sequencing-integrated cost simulation.

Every discipline federates into one model, and we run clash detection against it on the cadence your BEP sets, to the tolerance each trade and stage requires. Live conflicts are tracked to closure and signed off in the ICE coordination meeting, so the package that reaches fabrication has already been resolved in the model. For teams working across UAE programmes, that coordination cycle runs in your time zone and on your site walks.

We embed. A dedicated VDC lead owns your programme, joins your coordination meetings and walks the sequence with the project team, backed by a 260-person studio running the simulations. You get one accountable name on the contract, and capacity that scales against the programme rather than a permanent bench you have to carry.

Yes. Where the works interface with existing structures, we 4D-sequence against a verified scan-to-BIM record model so logistics and temporary works are planned against real conditions, not assumed geometry. It is the same coordinated model, extended to cover what is already standing.
