You will find the Wijnen building site for the De Citadel project in the Reinier Engelmanstraat in Amsterdam. Work preparations started in January 2020. The pilings work started in May. 149 non-subsidised rental homes are being built here. The apartments are expected to be rentable in two years.
This is not Van Wijnen’s typical building site. It is located in the middle of a residential area, which means that it is surrounded on all sides by buildings. A cramped building site requires the contractor to plan properly and have a sound logistics process. Materials are immediately put in the right place when unloading the lorry. There is no room for a storage place where materials can sit for any length of time. It’s like building on a postage stamp. Which is quite fitting given that this site used to house a PostNL mail sorting centre.
This building site is so cramped that supply lorries have a very small turning circle to enter and leave the site. Van Wijnen first looked for a suitable solution. But they were not 100% satisfied with what they found and asked Heras for advice. Heras proposed the solution of installing two sliding gates as a double sliding gate. This creates 14 metres of free passage.
Heras was commissioned soon thereafter. In the meantime, two double sliding gates have been delivered and assembled. The gates are secure on Stelcon plates by drilling. Currently, the customer opted for manual operation in combination with a gatekeeper. This solution now works perfectly. In the future, it will always be possible to choose to electrically operate the gates (remotely).
