For the "De Stordeur" project in Leuven, d-CONCRETE! provided the concrete beams, columns (rectangular and round), slabs and TTPs. The project is a collaboration between a General Contractor (specialized in steel construction) and three Clients. These Clients will each execute their own specialty in this building (executed in 5 phases) when it is finished, namely: one will have a liquor business, the other a garage and the last a climbing hall. The building itself consists of 35 % steel and 65 % concrete. As the General Contractor is specialized in steel construction, we have collaborated conscientiously with it in order to make the project a success.
This collaboration consisted mainly of the exchange of our Tekla models and frequent mutual deliberation. As the site is situated next to a canal, we had different building materials delivered by water (beams and slabs). The following is quite remarkable: one climbing hall with a climbing wall 18 meters high starts at 13 meters from the ground and another climbing hall with a climbing wall 11 meters high starts at 20 meters from the ground. Because the garage (+ parking roof) is situated on the first level, we also included an escalator and an access ramp in our BIM model.
It was a big challenge to adapt the steel structure to our concrete structure, and in particular the corbels. These corbels carry the concrete beams as well as the steel beams (sometimes simultaneously)! Another remarkable point is the length of the columns, sometimes up to 20 meters (with corbels up to 1.7 meters)! Two cranes were needed to fit these columns.
What made the project successful
The close cooperation between our subsidiaries and the controlling engineering agency.
