Formwork with one-sided anchor technology saves labor time

Right in the center of The Hague, the Education and Culture Complex (OCC) is under construction. Central to the complex are the four halls, each with its own shape and atmosphere. Due to the high acoustic requirements, a huge volume of concrete is being processed. A technically and constructively challenging project for construction consortium Cadanz (Boele & van Eesteren | Visser & Smit Bouw), which is saving considerable labor time by using PERI formwork with single-sided anchoring technology.

The OCC is being realized on the Spuiplein and will soon be the new home of the Dance and Music Center The Hague Foundation, the Netherlands Dance Theater, the Residentie Orkest and the Royal Conservatory. According to Birgit Maathuis, executor of construction combination Cadanz, it is a unique '(concrete) project' by Dutch standards. "Both in terms of size and structural challenges. Everything here revolves around mass. The complex more or less consists of seven independent units: four halls - the theater hall (1,500 persons), concert hall (2,500 persons), ensemble hall (600 persons) and rehearsal hall (200 persons) - and three stability cores that are all individually founded and constructively separated from each other."

PERI MAXIMO
The concrete structures of the halls and stability cores will all be cast on site. Cadanz relies on PERI's MAXIMO panel formwork. "It is a modular formwork system that is easy to assemble and disassemble, and last but not least, gives an attractive result," says Maathuis. "We deploy different types of PERI formwork, the biggest bulk of which is surely the MAXIMO." John Appelhof, project manager of PERI BeNeLux can agree: "The OCC is the largest project for us at the moment in the Netherlands. There is about 2,800 m² to MAXIMO formwork on site. The big advantage of this type of formwork is the one-sided attachment without spacers and cones. This saves an enormous amount of time. And for the realization of the high walls of the halls (up to 38 meters high) we supply our CB climbing system, a crane climbed system to realize great heights quickly and efficiently." Maathuis is also enthusiastic about the formwork system. "Our people are very familiar with the PERI system and enjoy working with it. That makes it possible for us to realize large volumes in a short time. Hundreds of cubic meters of concrete are poured every week."

One-sided mounting and dismounting
The one-sided fastening and dismantling of the MAXIMO formwork certainly comes in handy at the OCC, as halls are being realized one above the other. Maathuis: "This is immediately where the complexity of the work lies. Right next to both lower halls, the walls for the halls above are being realized, which rest on their own foundations, also right through the basement floor. We are now fully engaged in the concrete work and expect to complete the concrete work in the second half of 2019." The actual completion and opening of the OCC is scheduled for 2021.
