Virtual Design & Construction
Virtual Design & Construction (VDC) is building the entire project virtually (digitally) before being built in the real world. VDC utilizes Building Information Modeling, clash detection, and construction animation to render a 3D model of the project.
“In my opinion and experience, it would have taking an additional 20% of on-site labor hours to complete this project, with a very negative effect on the construction schedule.”
David Walker, Supervisor – Raleigh, NC
Benefits of Virtual Design and Construction
Services:
-
Rendering of 2D and 3D drawings
-
Total Station Robot - Take the field layout, convert to CAD and use the Trimble robot to locate points for hangers, turn-ups, etc.
-
Clash Detection/Coordination of trades - the coordination and Clash Detection of the MEP trades using 3D models.
Accuracy:
-
Coordination and clash detection of MEP allows for the discovery and correction of issues before implementation.
-
RTS is used to pinpoint control points for field layout, reducing the error rate over string line field layout.
Quality:
-
Components can be prefabricated, simplifying the on-site installation process, increasing overall quality.
-
Controlled factory environments allow for precision and predictability.
Cost:
-
The use of services, accuracy, and quality decrease on-site errors, wasted material, and scheduling overages resulting in a lower project cost.
Facility Management:
-
A 3D model of the facility is more accurate and simplifies the maintenance process.
VDC Process
- Planning - Supervisors/foremen plan conduit rack layouts, group circuits, and develop an install plan.
- BIM - The field layouts are modeled in 2D or 3D, depending on the project’s needs and availability of files.
- Coordinate - If required, the model is put through multi-trade coordination (HVAC, Fire Protection, Mechanical Pipe, etc.) and clash detection.
- Submit - Once modeled and coordinated; drawings will be produced with all pertinent information to install electrical systems.
- Prefabrication - A prefabrication detail package is reviewed and submitted. Components are prefabricated.
- Construction - The model, the RTS points, and the prefabricated components are used in the field to increase accuracy, efficiency, and productivity.
- Facility Maintenance - accurate 3D modeling supports long-term maintenance and service needs of each project.
