Reuse of roof tiles, pavers, carpet tiles and more

As many environmentally friendly solutions as possible

The 38 senior apartments in the Oranjehof will be built traditionally. The main construction consists of sand-lime brick and wide slab floors. There is a lot of attention to sustainability and circularity. The homes will function Zero-Meter. "And wherever possible, used or recycled materials will be used," says Hubèrt van der Graaf, project manager of Jongekrijg+Maasbouw, part of Bouwgroep Schrijver

Foundation with Olivier piles

A construction challenge already arises at the foundation. Next to the plot is a high-pressure gas pipeline, which could pose a danger to the immediate vicinity in case of vibrations. "So we had to apply a vibration-free piling system," Van der Graaf explains. "Add to that the pile length of 31 meters and you have a challenge. To do this, we used a 36-meter high pile driving rig to drive 104 Olivier piles into the ground."

Sustainability and circularity

In the construction team phase, Jongekrijg+Maasbouw actively sought ways to improve the sustainability

ambition of HW Wonen. Optimal insulation, ground-source heat pumps and solar panels make the homes independent of fossil fuels. But it goes further.Roof tiles are reused in facades, paving tiles are reused in walkways and for carpet tiles a remnant batch is sought. Traditional PIR is giving way to mineral wool made from 70% recycled glass, window frames are produced with FSC-certified wood, and the PS box is to make way for the traditional box again, so that no tempex ends up in the ground. 

Shared ambition

For Jongekrijg+Maasbouw, this sustainability ambition is more than welcome. "It's important and it suits us. Our own housing was built completely circular, to show how extensive the possibilities are in this area. Surely that says it all." The task now for the construction of Oranjehof is to make the building wind and watertight as soon as possible, so that the shell construction can flow smoothly into the finishing.

Pilot project Wkb

For Jongekrijg+Maasbouw, Oranjehof is also a pilot project to prepare for the Building Quality Assurance Act, which will take effect in early 2023. To this end, it has worked with an external quality assurance company to draw up a quality assurance plan. Van der Graaf: "Important benchmarks, such as reinforcement in foundations and floors, structural components, insulation connections, but also certificates, attestations, et cetera, are recorded in this quality assurance plan report. This allows us to demonstrate to our client that the work has been carried out correctly and that the materials have been applied correctly. This still requires extra effort now, but our executors are now ready to take over the work of the external quality assurance officer."
