Prefab and modular building methods are on the rise. Not only in the architecture, but in the entire building sector: more and more installers are integrating prefab into their workflow. Depending on the type of project, the location and the construction team, this can deliver many productivity advantages.
Transport to the site
An example of one such productivity advantage is clearly evident in the Brouwerseiland project. In this project, DWT Groep is looking after the installations for various houses in the Zeeland Delta.
The sandy roads on the different islands make it difficult for transport to access the construction site. Prefab offers a solution for this: by preparing elements as much as possible in a clean workshop, traffic around the construction site is kept to a minimum, thereby reducing any problems caused by sand and the weather. To maintain transparency during the design phase, DWT Groep is opting for BIM. Aart-Jan Stroober, work planner at DWT Groep: “Revit does not need to cost more time but does provide a great deal of insight and possibilities, also with a view to prefab.”
Prefab in the BIM workflow
By involving prefab early on in the building process, the workflow changes. The choice of manufacturer will in fact have to be made in advance. Engineer download manufacturer-specific content via MEPcontent, so that they can start modeling with up-to-date, orderable products, complete with article numbers and price information.
Engineers are using the prefab functionality, which is automatically included in Stabicad, to create simple prefab sets with several prefab elements. The coding that is applied to these sets can be adjusted. With the press of a button, several prefab sheets and material lists can then be simultaneously generated based on the information in the model. When link to ERP software (for example, Syntess) is applied, the components for the prefab sets can be ordered directly. This creates an efficient workflow.
Information for the construction site
Prefab is also being more frequently applied in non-residential construction. Take for instance the prestigious EPO New Main, for which Hoogendoorn is looking after the sanitary installations.
René Kamer, Head of Implementation at Hoogendoorn: “We work as much as possible with prefab; that is a must in terms of efficiency. This is certainly the case for the sewer system, for which almost everything is supplied prefab. To this end, we have been using the prefab functionality from Stabicad to great effect, which generates prefab drawings with cutting lists for our men at the workplace. Engineers no longer have to measure the pipe lengths and calculate the cutting dimensions at the site themselves. Moreover, the circumstances for assembling are better at the workplace that at the construction site. Without prefab in BIM, you simply cannot work efficiently and maintain the construction tempo.
