Plastic site road at the University Hospital of Tübingen
Perfect protection for sensitive construction sites
From 2023, the Gynaecological Clinic of the University Hospital of Tübingen is to receive a new extension for the prenatal and fertility outpatient clinic as well as two nursing wards. In order to be able to increase the bed capacities in advance, ten bed modules for about 20 beds were already installed in June 2020. The company used the plastic site road from thyssenkrupp Infrastructure to protect the largely listed hospital site. The site road elements proved their worth both in the delivery of the modules by heavy-duty transporters and in the positioning of the mobile crane required for their installation. These include low weight combined with high load capacity and low transport and processing costs. In their conclusion at the end of the work, which was completed to the client's satisfaction within a week, the construction partners agreed: "The use of the plastic site road made a significant contribution to optimally protecting the paved access road to the installation site as well as the surrounding park and meadow areas."
All requirements fulfilled
The plastic elements are real lightweights. No special vehicles are required for transport to and from the site. A single truck can transport up to 75 panels, depending on their size - transport costs are correspondingly low. The elements are made of polyethylene, measure 3,000 mm x 2,400 mm x 45.5 mm and can be laid as far as possible without prior earthwork. Despite their relatively low dead weight of around 280 kg per panel, the load-bearing capacity is approx. 160 t/m2, depending on the substrate. In addition, the elements are easy and quick to lay and ensure optimum load distribution. This contributes to economical processes on the construction site. On a Tuesday, the site road elements were delivered to the hospital site and laid there by a truck with loading crane and a large forklift. After the paved access road and the meadow areas as well as the site for the mobile crane had been laid out accordingly, the ten modules that had been ordered were transported to Tübingen and on site the mobile crane placed them on the individual foundations with steel lattice girders that had been prepared in advance and connected to each other.
The real millimeter work was completed in just a few hours. The next day, the site road elements could already be dismantled, and after removing the plastic sheets, no damage to the subsoil could be detected. After the outer cladding of the modules and the installation of the remaining medical technology, the station was able to go into operation on schedule in September 2020.
