Virtual Design and Construction (VDC)

Design and construct buildings digitally

VDC in essence, is completing a virtual construction of any project before commencing physical construction. The key benefits being the identification and minimisation of design and construction issues before they arise; thus minimising cost over runs and ensuring a timely project delivery.


To illustrate the process and activities involved in this holistic framework, below is a process overview showing how our VDC projects are executed. The overview uses an illustrative example to highlight the extensive benefits to the project from utalising VDC.

Stage 1

Requirement defining & Concept design

Our team of architects works closely with you to develop a concept design. Early on, this takes the shape of hand stages. Once a design direction is finalised, a low fidelity 3D model is create to help visualise the concept.

Itterative process

Clients are typically heavily involved in the concept development process. Design at this stage go through multiple rounds of iterative revisions to develop a bespoke concept design.

The final output from this phase will include sketches and low fidelity renders covering the following:

  • Facade
  • Elevations
  • Layout
  • Landscaping

Additionally, low fidelity renders of external facades will be delivered, along with an itemised list of features.
Stage 2

Detailed Design

The Detailed Design phase has three stages. Client input and revisions are incorporated at the end of each phase, namely: DD50, DD80 and DD100.

The detail design phase can take anywhere from a few weeks to several months. This will depend on the scope of work, specialist subcontractors and client feedback loop.

Design Development 50% (DD50)

This is where the building takes shape. The architecture and structure elements are being finalised, space planning and MEP designs are being developed.

If specialist sub-consultants (ID, Lighting, Way-finding), are to be appointed, they are appointed at the start of DD50. The final DD50 submission will incorporate elements of the specialist sub-consultants works into the overall design.

Design Development 80% (DD80)

Architecture and structure design is finalised in the early stages of DD80. By the end of DD80, other elements, including space planning, MEP and sub-consultant designs are finalised. Only overall coordination is remaining for the final stage DD100. In some cases, ID can be finalised as part of DD100.

Although Renders are created at each stage of Design Development, High fidelity and photo realistic visual renders of the external facade are created as part of DD80.

Design Development 100% (DD100)

All elements are coordinated and the building is digitally constructed. Any issues that arise from digital construction are rectified. Final project renders and walkthroughs are created. By the end of DD100, the project is ready for construction.

Stage 3

Preparation of Tender Documents
and Project Management

Once DD100 is approved, accurate BOQs, IFC drawings and specifications will be extracted from the BIM models and all tender packages, including the following will be created:

  • Main Contractor
  • MEP Contractor
  • Cealing & Flooring
  • Fitout and joinery
  • Drywall
  • Signage

Shop drawing submittals in BIM will be included as part of these tender packages. These will later be used to create a Digital Twin, which will help reduce both the environmental and financial cost facilities and asset management.

Following awards, JES will manage the project and oversee site work to ensure designs are followed and that construction is progressing as planned. The following falls within the JES purview as part of project management and site supervision.

  • BIM Management
  • Site Supervision
  • 4D Progress Reporting
  • Risk Management
  • Validating Authority Requirements
  • Coordinating Government Approvals

Reporting schedules are determined by client requirement and are presented in 4D Simulation format.
Stage 4

Handover and Digital Twin
Development (Optional)

Following completion and authority approvals, JES will organise all deliverables and perform final snagging and commissioning, to ensure the project is built as per standards. The project will then be handed over to the client or facilities management teams.

We are then able to utilise LOD 500 (as built) BIM models to develop Digital Twins. Over the project life cycle, Digital Twins can enable significant savings in both asset management and environmental costs of the development.
