Owners whose previous projects have employed Building Information Modeling (BIM) tend to want to use BIM again on future projects. Why? BIM projects produce better buildings faster and more affordably—smarter buildings with lower operations and maintenance costs. Indeed, BIM evangelists like Holland’s HFB Group are increasingly finding that they’re preaching to the choir when they try to sell owners on the benefits of BIM.
“BIM project owners almost always want to use BIM again,” says Sharif Ben Chamach. “BIM helps us design and build higher-quality projects faster and more affordably. But for owners, the real benefits arrive over the long haul, as digitally connected systems and automated operations drive better performance and lower facility management costs.”
Already a fan from previous projects, the Kingdom of the Netherlands was enthusiastic about using BIM for the renovation and expansion of the Palace Het Loo. BIM could accelerate the design and construction of the palace, once a residence of the Dutch royal family and now a museum. It could also streamline the installation of smart building components, like a climate control system, paving the way for increased comfort for museumgoers plus lower operations and maintenance costs.
Because the palace was built in 1684, there were no original design documents to work from—so HFB had laser scans taken of every inch of the palace, inside and out, and used the resulting point clouds to create a 3D model in BIM that is an exact copy of the building. Now, during the design phase, the project is also using BIM to conduct virtual construction and speed subcontractor design submission and clash detection.
In the field, team members connect, collaborate, and keep up to speed on the project using BIM. Since this is such an old building with extremely limited documentation, team members are also adding to the intelligent model information about existing building elements, including the materials in floors, walls, and ceilings.
In so doing, the team is making it possible to connect the entire palace using sensors and smart systems. In addition, in the intelligent model, the project is creating a single source of all information about the building and its components.
So far during the design phase of the Palace Het Loo project, HFB has shaved weeks from the schedule by using BIM. Previously, the palace used a Microsoft® Excel® spreadsheet to track information on its nearly 600 rooms. Now, despite a significant expansion, that information will be part of the intelligent model—along with all the additional data documented during the design and build phases of the project. Between that and the installation of new smart systems, when construction is complete the palace will offer improved performance along with lower operations and maintenance costs. As a result, the owner will be more likely to require BIM on future projects—and HFB will be better positioned than ever to help the increasing numbers of owners around the world to use BIM.
After HFB Group finishes construction, the BIM model will be a single source of information about the building and its smart systems
