Installation water, sewer, rainwater installation and dry fire lines

'Challenges also make work fun'

Installatiebedrijf Werkendam (IBW) provided the complete S-installation for the Waterside II project: water, sewerage, rainwater installation and dry fire lines. The company also took on the installation of the plumbing system.

IBW operates in four disciplines: plumbing, electrical, roof and zinc and lead work. The company works for medium-sized and large contractors and housing associations. Since last summer, two people from IBW have been walking continuously on the Waterside II construction site. Depending on the construction speed of the contractor, this will be expanded to three or four people during the final construction. The cooperation goes smoothly, says IBW project manager Gerrit Vermeulen. "The start of each project requires some flexibility from all parties, but at some point a train is created. There was only some delay because some prefabricated parts were not delivered to the contractor, but we made up that time later."

The work on Waterside II is fairly standard for IBW. What made it interesting is that all the apartments are different and the penthouses will have more and more luxurious plumbing. "With a standard project, after ten drawings you know the dimensions by heart. Here you have to look closely at each apartment to see what the situation is and what will be in it. In addition, the building has a stepped structure, which presented challenges with determining the outlet of the vents. But that also makes the work fun."

The WKO supply in the complex is centrally controlled. Therefore, additional hot water protection was installed: if the cold water pressure drops, the hot water protection shuts off the supply in the apartment, preventing the danger of scalding. A large part of the installation is installed against the ceiling of the parking basement. This is quite a challenge. During the development phase, this was drawn up in consultation with all parties. Vermeulen: "Because of the low height it is already difficult to get the necessary slope. In this regard, the use of BIM really does offer a solution, because everything is modeled in 3D and any clashes are already seen on the screen and not only in practice."
