All participants work in BIM (client, architect, advisers and executive companies) in one design model.This integral and integrated work method is geared towards collaboration from the earliest point in the design process.
Using the right software and storing information in a central location enabled all parties involved to share their knowledge and expertise in a structured manner, facilitating optimal communication.
Implementing BIM not only optimises the design process; it also allows the client, users and all other parties involved a lot of insight into the design. In this model, elements are not lines; they are objects with information. When the model is finalised, it basically takes one button to display all amounts and material specifications. In a 3D world, consequences of design choices immediately become clear, making it easier to get a clear view of feasability.
With BIM, the client is a full member of the design team. After completing the design stage, the executing parties can use the model to efficiently realise the building, greatly limiting the cost of failure.
During the design stage, the parties involved enter all relevant information in the BIM model. In the execution stages, the executive parties use product information from the design stage. In the execution stage, the process and product information is developed further, so that all information needed to manage and maintain the structure in the maintenance stage remains readily available. This stage contains major savings opportunities since a large part of the costs of maintaining a building are made in this exploitation stage.
In essence, Van Rossum is working on the third generation of BIM projects. We gain more experience during every generation, which we implement in following projects. We are able to make optimal use of the advantages in this third generation of projects.
In a number of projects, this has been carried through in the execution as well. All information from the subcontractors was entered three-dimensionally as well, making deviations visible through clash checks. This didn’t run as smoothly as with the other projects, and the suppliers in particular still have difficulty with this method, but our experience is that it absolutely provides added value in the case of clear agreements. Currently, around 70% of our employees are able to draft in Revit.
