Virtual Design & Construction (VDC) is an approach in which not only the Product (such as buildings, roads or bridges), but also the Process (management of the design) and the Organisation (parties involved) are modelled in order to come to an optimal design.
VDC is based on 3 main pillars: visual, measurable and integral.
- Visual: by using BIM and design in the Royal HaskoningDHV iRooms
- Measurable: by making the objectives from program of requirements measurable
- Integral: by jointly deigning with stakeholders (discipline-transcending) to an optimal design
The gains of Virtual Design & Construction
By using VDC, all design parties and consultants are involved in the design of the product, process and organization. The use of the Royal HaskoningDHV iRoom and the application of BIM stimulate a comprehensive and integral approach leading to the best design. It also proves that the risks in the project are reduced considerably and substantial time gains can be achieved during the design and construction. This also means that the cost of financing during construction can be significantly lower than normally is the case.
Advantages in a nutshell
- What You See Is What You Get
- Transparent design choices
- Support of and collaboration with client and/or other stakeholders
- Reduction of construction lead time by ± 10%
- Reduction of contingency costs up to 50%
The modelling of the product is established by means of BIM: a dynamic and digital 3D model of the building, in which all the information is linked and accessible to all parties at any time. In addition, Royal HaskoningDHV iRooms facilitate integrated design sessions, using interactive ICT facilities and an intelligent BIM. By virtually building the project (for example building, bridge, or road) during these design sessions, all disciplines develop a better understanding of the design and any bottlenecks become clear very quickly. Not only the designers and consultants, but also the client and contractor(s), can be involved early in the process. This helps to prevent structural defects, which is a significant savings in the implementation phase. This approach results in a proven reduction of the contingency by 25-50%.
An efficient process is a prerequisite to achieve a good design and thus an optimal building. Process modelling is used to jointly determine at an early stage which parties, at what stage of the process, are necessary. The design process is not unilaterally imposed this way, but by all disciplines integrally determined. This practical approach ensures support between involved parties and guarantees an efficient design process. By also connecting the construction process to time and to the virtual model, more insight and understanding is created in the construction planning.
Research (Flagger & Haymaker, Stanford University, 2007) shows that most of the time of the design team is spent on managing the design. VDC also models this aspect of the design process, where it is very important to identify decision makers and decision terms. By modelling the organization and identifying the stakeholders, we can establish early in the process which stakeholders deserve extra attention. Next, the organization is connected to the process in order to decide to get clear decision terms. Simply put: who does what and when? This modelling results in a clear insight in the process and leaves more time for design work itself. Waiting for partial solutions or redoing the work belongs to the past.
