Key to Success in Implementing VDC
The virtual building design industry is seeing an upward trend worldwide and one of the key components driving this trend is the successful implementation of VDC. Virtual design and construction (VDC) is a process that provides a single platform for all project stakeholders to collaborate and make changes in a project, while working to budgets and deadlines. One of the main features of VDC is that it uses models and data to encourage regular communication between all stakeholders right till completion. What optimises success with VDC is the contribution of qualified professionals who deliver services quickly and at lower cost. One of the benefits clients enjoy from the VDC process is that they are provided with building information modelling (BIM) capabilities and information that help in design, project planning and construction. Collaboration between clients and contractors at earlier stages are enabled by the use of VDC. Thus, the need for rework is reduced, and project time and costs are saved. Changes are managed, workflow is collaborated, and documents are monitored in VDC. By identifying key goals, technical concerns are addressed early on. A cloud-based working environment helps collaboration in VDC. BIM in the construction industry facilitates the creation of a single model from design specifications, RFIs and equipment data sheets, helping clients monitor the progression of the project. Thus, VDC helps firms to: • Envision, modify and improve a project without wasting time or materials • Collaborate between contractors or subcontractors and clients • Establish sustainable elements into design • Track labour, materials and schedules for project completion • Provide digital delivery of plans for fabrication Consultants and MEP professionals must work effectively for the overall success of the VDC process. Consultants manage design, but coordination and installation are usually handled by separate trades – mechanical, electrical, plumbing, etc. Smooth implementation of VDC benefits all stakeholders concerned. By using BIM 360 Glue or Revit BIM software tools during design phase coordination, the model can be sent from design to construction. Also, coordination in VDC facilitates prefabrication. BIM modelling tools in VDC streamlines MEP coordination, identifying and resolving conflicts. The results of successful and effective VDC implementation include: • Complete fabrication of MEP elements • Reduction of rework for mechanical subcontractors • Less conflicts at field installations • Fewer RFIs occur in MEP coordination • Significant savings in cost and time Usually, coordination and installation are carried out by separate trades in the VDC process. Each may not have enough skills or resources to fully implement effective VDC, so profitable and timely delivery of projects could benefit from the right design partner. Advantage of Overseas VDC Experts General contractors usually have their own teams, but they do not always have enough modelling resources or the required skillset. VDC implementation requires expertise in handling precise data with the right tools. It is, therefore, preferable to employ a VDC expert from the relevant disciplines, who brings technical knowhow and experience in BIM virtual construction to the table. Western firms increasingly find that such experts are being located overseas, especially with experienced partners who have a large pool of qualified technical professionals and extensive experience working in the US, UK and other Western markets, leading to accurate design services, greater profits and on-time deliveries.
