Platform on new construction, renovation, restoration and transformation
The construction of Vivium Naarderheem's new healthcare building required speed, smart logistics and an integrated approach. For Lomans Totaalinstallateur, it was just such a project in which technology, teamwork and innovation came together beautifully. Mechanical engineering project leader Vincent van der Hoeven and chief electrical engineer Edo van Zomeren explain how they approached it.
With 220 care rooms, numerous washrooms and six floors, Vivium Zorggroep's care building is a huge job. “Really typical of a project for Lomans,” says Van Zomeren. “But the construction speed and the enormous size certainly make it challenging.” One of the solutions to make construction as efficient as possible was to work with prefabricated parts. “That was really the key to success for us.” For the electrical work, for example, the team worked with pre-assembled flush-mounted boxes with flexible, pre-wired hoses. “In the shell construction, you can roll those out at once. That saves an enormous amount of time.”
In the mechanical engineering corner, complete prefabricated bathroom skids were used: steel frames with sewage, air ducts, water pipes, a flow-through appliance and even a piece of interior wall in one element. “This allowed us to hoist two bathrooms against the ceiling at the same time,” Van der Hoeven says. “In such a small space, that saves days of work.” The large numbers of plumbing fixtures also arrived pre-assembled in trays at the construction site. “Everything was packed per two bathrooms. That made the logistics very efficient.”
Lomans took care of all climate installations, sanitary facilities and electrical systems. From fire alarm and evacuation systems to data networks, outbreak protection and the nurse call system: everything is linked via a self-programmed KNX building management system. Prefabricated equipment was also used for cooling and heating. The distributors came directly from Lomans' new prefab hall, which was put into use for the first time on this project.
The team worked entirely digitally. “We no longer use paper drawings,” Van Zomeren explains. “Via ACC models on the tablet or phone, everyone always has the current drawing work at hand.” In addition, the building was captured with a 360-degree camera. “It's like Google Street View, but inside. You can walk back in time, compare with the 3D model and see exactly what's where. That saves an enormous amount of searching. In the past we had to take individual photos and then of course the one corner you needed was not in the right place. Now you really capture everything. A very nice technique to work with. And it wasn't just us: our project partners also looked at our innovative methods with amazement.”
