Service 04 · 4D Simulation
Vultris links the programme to the BIM model so bid teams, planners, project leaders and clients can see the proposed method, test the sequence and make decisions with a shared view of the work.

The delivery problem
Vultris starts by checking the current information and responsibility structure. The proposal then focuses on outputs that remove or expose the actual constraint.
How companies appoint us
A tender animation, baseline review and recovery study are not the same service. The scope, level of detail and update cycle should match the buyer, deadline and decision.
Usually appointed by: Bid manager, planning manager or pre-construction director
The contractor or specialist bidder must explain a complex method, show control of logistics or distinguish its proposal before the tender return.
Typical scope: Bid-programme and model review, construction sequence, temporary works and logistics representation, review sessions, final animation and key stills for the written submission or interview.
Usually appointed by: Project director, planning manager, developer or PMC
The proposed baseline must be tested against the physical project before teams, access routes and work fronts are committed.
Typical scope: Programme-to-model linking, site setup and logistics phases, work-area and handover review, decision log and agreed 4D sequence for mobilisation.
Usually appointed by: Project controls, construction or package team
The team needs a clearer way to coordinate upcoming work, report progress or explain the effect of a change.
Typical scope: Rolling look-ahead simulations, critical-area studies, planned-versus-actual views, progress meeting material and updates tied to agreed status dates.
Usually appointed by: Project director, planner, contractor, developer or PMC
Several recovery ideas exist, but their effect on access, work fronts, logistics and other trades is not clear.
Typical scope: Targeted option modelling, side-by-side sequence comparison, constraint record and decision-ready visuals. Delay analysis is separate unless expressly appointed.
Usually appointed by: Main contractor, specialist contractor or design consultancy
A concentrated package—such as complex structure, façade, plantroom, fit-out or themed works—has difficult interfaces or installation constraints.
Typical scope: Focused model preparation, package sequence, access and installation review, interface workshops and a concise output for tender or delivery coordination.
What we can deliver
The final animation is only one output. The value comes from preparing the model, checking the programme structure, representing the real constraints and reviewing the sequence with the people responsible for delivery.
Review whether the activity structure, model breakdown and available information are suitable for the required 4D decision.
Agree the zones, work packages, temporary elements, logistics items, dates and review points that must be represented.
Connect programme activities to the correct model elements and locations at a useful level of detail.
Explain the proposed methodology, sequence, logistics, temporary works, key milestones and package handovers in the bid.
Test how gates, delivery routes, laydown, storage, lifting and changing work zones operate through the programme.
Focus on a difficult area or package such as structure, façade, plantrooms, specialist steel, fit-out or themed works.
Show upcoming work fronts, prerequisites and planned-versus-actual status using an agreed update process.
Compare alternative sequences or additional work fronts so the project team can see the operational effect before deciding.
What we need
What changes
Is 4D worth commissioning?
Not every project needs 4D. It earns its place when the physical sequence is difficult to explain, test or coordinate—and when the project team will use the findings.
Common questions
Yes, if the available programme, models and decision route are sufficient for the required scope. We first confirm what can be delivered credibly within the remaining tender period.
No. Tender and early-stage models are often incomplete. We assess whether the existing geometry is usable, what must be prepared and which missing elements need simple temporary representation.
We can review and help structure programme information for 4D use. Formal planning responsibility remains with the appointed planner or contractor unless programme development is expressly included in our scope.
No. A video can support a bid or meeting, but the core service is checking the link between activities, model elements, work areas, access, logistics and temporary conditions.
No simulation can guarantee delivery. It can expose physical and sequencing assumptions, improve communication and support review; programme feasibility still depends on durations, resources, productivity, procurement and other planning inputs.
We confirm this during the initial review. The practical requirement is usable schedule data, suitable model geometry and a clear way to identify activities, zones and work packages.
