VDC (Virtual Design Construction)

Virtual Design Construction (VDC) Benefits

  •   Quickly and accurately evaluate the implications of “what-if” design scenarios and changes
  •   Systems allow for utilization of the conceptual model to provide cost and systems analysis
  •   Provide 3D visuals for better communication
  •   Visually evaluate sequencing and scheduling in a simulated environment
  •   3D coordination to prevent system collisions and improve installations
  •   Improved scheduling of activities that overlap business operations
  •   Improved quality through increased prefabrication
  •   Improved site safety
  •   Reduced waste

With the vast majority of a project's cost dedicated to the construction phase, real savings of time and money can be experienced in the field. By pre-planning sequencing and reducing conflicts and changes during construction, our project team can avoid many of the mistakes that erode budgets and schedules. The use of VDC for clash detection while coordinating various subcontractors has proven highly effective. The ability to conceptualize the construction and detect error beforehand reduces the time that would be spent on the job site developing a new planned saves money that would be required to pay off extra materials to re-route the issue. 

Project Coordination

Success in VDC requires more than just a firm grasp of the technology. We place a premium on early team integration, goal congruency, and extensive communication among project stakeholders, knowing the value it brings to the construction process. This collaborative approach has become an integral part of our building process.

Clash Detection

Clash detection is an important and integral part of the VDC modeling process. Clash detection arises out of the fact that, in VDC modeling, there is not just one model, but several, that are, in the end, integrated into a composite master model. Our team involves each discipline: structural engineering, MEP engineering, environmental engineering and etc. We create a model, independently of all the others, based upon the architects original model, which is the starting point for all the other disciplines. After each of the disciplines has finished their work, clash detection begins, which is the process of finding where the models "clash": elements of separate models occupying the same space, or with parameters that are incompatible, or in 4D BIM modeling, a time sequence that is out of order.

Field Coordination

In the field, our team utilizes VDC to streamline construction operations. Using virtual models to help us coordinate construction documents and activities, and identify sequencing and access issues, we can better manage the quality and pace of work, and ensure a safe job site.


Virtual Reality / Augmented Reality / 3D

Our team gives our clients visibility into their finished facility long before construction is complete. With insight from virtual walkthroughs, they can visualize what their project will look like and can make informed design decisions to ensure that the end product meets their vision. 

Scheduling / 4D

4D scheduling in VDC allows Journey Group to see problems scheduled in the work durations and analyze congestion and accessibility more effectively than through a standard Gantt chart.  A more powerful aspect of 4D schedules is that, unlike a static building model, they are in a dynamic state.  By linking time to building components, it is possible to virtually construct the project using the actual BIM model.  The Family Health and Wellness Center located in Columbus, Nebraska is a complex project consisting of three different building types, precast concrete panels, metal building system and structural steel with stud infill.  The use of 4D scheduling allowed the team to virtually construct the building looking for possible issues with the delivery of materials and sequencing of the construction.  The 4D scheduling also helped with materials management of the precast panels.  By requesting only the panels that were needed for the immediate construction, storage of large quantities of materials on the site were reduced as well as the handling of materials more than once.

Cost Estimating / 5D

With VDC, Journey Group maintains greater control over a project’s schedule and budget. Combining a project’s cost with the virtual model allows us to help our clients evaluate material selections, knowing instantly how each change will affect the facility’s projected costs. The use of quantification on projects such as the Avera Medical Clinic located in Mitchell South Dakota provided the opportunity to verify quantities of materials provided by subcontractors to help ensure that materials in the project were accounted for. This double-check helped provide the owner with a more complete and accurate overall project cost.
