VDC Services
Plan and manage construction on the model before you commit resources on-site. Powerkh works as your off-site virtual design and construction department — reviewing constructability, running coordination, sequencing the build, and extracting quantities so your field teams execute with fewer surprises.

Virtual Design and Construction Services for Contractors
VDC (Virtual Design and Construction) is the practice of using building information models to plan and rehearse the entire construction phase before work begins on-site. It combines constructability review, model-based coordination, 4D sequencing, site logistics modeling, and quantity extraction to test how a design gets built and resolve issues on screen.
VDC is more than clash detection. It is the practice of using building information models to rehearse the entire construction phase — testing how the design gets built, in what order, with which crews and equipment, and at what cost — before anyone breaks ground. General contractors and trade partners who run projects through a VDC workflow catch buildability issues, sequencing conflicts, and quantity gaps while they can still be resolved on screen.
Powerkh acts as an outsourced VDC company for contractors who need this capability without building an in-house department. Our engineers combine constructability review, model-based coordination management, 4D sequencing, site logistics modeling, and quantity extraction into one construction-phase service. With 400+ delivered BIM projects for clients across the US, UK, and Europe, we know how to translate design models into information your superintendents and project managers can actually use.
Why Contractors Outsource VDC to Powerkh
A VDC department on demand
Get the output of a full virtual construction team — coordinators, modelers, and 4D planners — scaled to each project, without recruiting or fixed overhead.
Catch problems before mobilization
Constructability reviews and coordination on the model surface missing details, unbuildable connections, and trade conflicts while a redesign is still a model edit, not a change order.
One partner across 3D, 4D, and 5D
Coordination, sequencing simulation, and model-based quantities come from the same team working on the same model, so nothing is lost between disciplines.
Field-ready information
Deliverables are built for the jobsite — coordinated models, installation sequences, logistics plans, and quantities your foremen can act on, in imperial or metric units.
Our VDC Services
Constructability reviews
Model-based analysis of the design against real construction methods — flagging details, tolerances, and connections that will not work in the field.
Coordination management
We run the multi-trade coordination process end to end: model federation, issue tracking, meeting support, and sign-off — building on our dedicated BIM coordination and clash detection service.
4D sequencing support
Construction sequence simulations linked to your schedule, covered in depth by our 4D BIM scheduling service and delivered here as part of the wider VDC workflow.
Site logistics models
Models of cranes, hoists, laydown areas, temporary works, and access routes so site setup is planned on screen instead of improvised on day one.
Quantity extraction
Model-based quantity takeoffs for estimating, procurement, and progress payments — the foundation of our 5D cost services.
Field BIM support
Ongoing model updates, viewpoint packages, and BIM 360 setup so site teams work from the current coordinated model, not stale drawings.
How We Work as Your VDC Partner
-
Scope the engagement
Send your models, drawings, and project goals. We define which VDC functions you need — from a one-off constructability review to full construction-phase support — and provide a free quote.
-
Set up the model environment
We federate discipline models, establish naming and coordination standards, and configure BIM 360 or your preferred common data environment.
-
Review and coordinate
Constructability findings and coordination issues are logged, prioritized, and tracked through resolution with your design team and trade partners.
-
Sequence and quantify
The coordinated model is linked to your schedule for 4D simulation and used to extract quantities for procurement and cost control.
-
Support construction
Through the build, we keep the model current, produce lookahead visuals for site meetings, and answer model questions during your working day — our English-speaking team is available 8:00–18:00 UTC+2, Monday to Friday.

FAQ
What is the difference between VDC and BIM?
BIM is the model and the information inside it. VDC is how contractors use that model to plan and manage construction — constructability review, coordination, sequencing, logistics, and quantities. Powerkh provides both: BIM production services and the VDC workflow built on top of them.
Who are VDC services for?
Primarily general contractors, construction managers, and trade partners during preconstruction and construction. If you need to verify buildability, run trade coordination, or plan sequencing and site logistics, VDC is the service that ties those activities together.
How does this relate to your BIM coordination, 4D, and 5D services?
Those pages describe individual capabilities in depth — clash detection, schedule simulation, and cost. VDC is the umbrella engagement where we combine them for a construction project and manage the process, not just deliver a single output.
Can you work with models produced by our architects and engineers?
Yes. We take design models in Revit, IFC, or NWC, audit them for construction use, and build the VDC workflow around them. Where models are missing, our team can model from 2D drawings first.
How much do VDC services cost?
We price hourly based on the scope you need. After reviewing your models and project requirements we send a free quote, and you pay only after the work is delivered.
