Platform on civil engineering, underground infrastructure, energy, construction equipment & construction machinery
The walls of the sunken N206 ir. G. Tjalmaweg will be finished with a wooden slat wall. A mix of climbing plants will grow around the slats from above and below. ZND Nedicom is taking care of the delivery, engineering and assembly of no less than 7 kilometers of wooden slat wall and relies on the expertise of its regular suppliers Platowood and sawmill Maas Reusel.
Originally a specialist in roofs and facades, ZND Nedicom has been focusing more and more in recent years on wooden cladding and specials in infra. "We notice that there is more attention for building with wood. Also in the civil sector," says Marc Hesen, senior account manager at ZND Nedicom. "In fact, the Tjalmaweg is our first real infra project for which we were approached by Boskalis in 2019. But in the meantime we are also working on other infra-related projects. Our extensive experience with wooden cladding in residential and high-rise buildings proves to be of great added value in this, as does the fixed triangle with short lines of communication between ZND Nedicom, Platowood and Maas Reusel for that matter."
Based on the Final Zoning Plan, ZND Nedicom made a mock-up of the slat wall in the preliminary phase. Hesen: "We slightly optimized the architect's proposal and proposed more sustainable types of wood. From there the choice was made for Platowood Spruce, originating from responsibly managed forests in Northern Europe, FSC®-certified and thermally modified without chemical additives. A truly sustainable choice. We then entered the engineering process with Boskalis." Tim Vrenken, project manager at ZND Nedicom and also ultimately responsible for this project adds: "All in all, we spent more than a year on the engineering process to solve all the structural challenges, such as mounting the rear structure at the site of
the reinforced ground structure and the
concrete L-walls."
The rear structure consists of wooden uprights with a horizontal battens to which the slats are vertically attached. "The entire rear construction is also made in Platowood Spruce," says Vrenken. "The walls are efficiently prefabricated at Maas Reusel into manageable 'racks' 1.20 meters wide and 1 to 6.5 meters long that we assemble in phases on site. The beauty of our cooperation is that Platowood provides the flow of materials directly to Maas Reusel. The first wall elements have already been assembled by us. The aim is to assemble about 120 meters every week. That includes the installation of the rear construction largely in ground anchors. So with a length of 7 kilometers and a total surface area of 22,500 m2 we will be busy for some time," laughs Vrenken.
The slat wall extends at the top to above the entrance and exit and serves there as fall-through protection. ZND Nedicom is also providing the ceiling covering and parapet wall of the bicycle tunnel. "A project that definitely tastes like more," concludes Hesen.
