Construction in progress at CombiVliet (50 ha)

Since March this year, CombiVliet has been sending out regular construction updates on its 4th greenhouse in the Netherlands. The nursery is expanding by 12.2 hectares, which means the greenhouse acreage at the NoordVliet location is growing to 50 hectares.

In March, Havecon finalized the foundation, and started fitting the drainage. They began assembling the steel construction as well.

On behalf of heating company Dalm, FBO welded the pipelines in the greenhouse. Later that month, Havecon finished fitting the drainage of the 12 hectare greenhouse. All materials for the drainage were delivered on time by Holstein Waterservices.

The "men of steel" had to pay attention to where to put which columns, because here and there the columns had holes for electricity and lighting. Marco Broch dug in the 20,000 Volt cables.

In April, Havecon was busy putting up the steel construction for the greenhouse. Despite the rain, which was quite heavy at times, construction moved along steadily.

By then, all the heating pipes were in the ground. Only the (PVC) CO² pipelines needed to be laid, but that wasn't possible until the glass was laid.

The glazing itself moved along speedily. In two weeks, over 6 hectares (half the greenhouse) was glazed by Havecon. The pipelines next to the concrete path were finalized as well, with Welvreugd putting the finishing touches to the PE line.

CombiVliet itself started mounting the lighting, produced by Stolze, in the bars. Stolze also supplies the control panels for in the greenhouse. PDI mounted the screen motors and screen trays, while FBO started putting up the HT groups in the greenhouse.

Last week, Havecon had fully glazed the entire greenhouse, despite snow and hail on April 27. All the walls were up as well. Now all that remains are the finishing touches, like mounting the wire arches and preparing the doors.

All CO2 pipelines have also been fitted, starting with the large 630 mm pipes right down to the smaller 125 mm pipes. Alfen has placed the first transformers between greenhouse 3 and 4, according to plan.

PDI has been working full steam ahead, with almost all top wires finished, and all wall screens mounted. Dalm is working on assembling the distribution pipes for HT and LT heat. Half of the greenhouse is now ready.

Marco Broch is working on digging for the drainage pipes, and Welvreugd is digging pipes for the drip system. This is pretty much the last of the digging that needs to be done in the greenhouse. Now CombiVliet will work on leveling the greenhouse surface.
