CCL Structural Solutions

CCL has designed and installed the for Lighthouse, the tallest residential tower in in cooperation with Ramboll and Per Aarsleff A/S. The post-tensioned slabs are each 200 mm thick and span up to 10 m.

The 142-meter-tower, together with two lower-level side buildings, will provide 400 homes at a unique location at the tip of Aarhus Island, providing first-class views of the city, the bay, and the forest.

CCL used the Maturix | Real-time concrete monitoring system to monitor concrete strength development at Warwick University Faculty of Arts Building, where the company designed and installed post-tensioned slabs and beams.

Because the Maturix system enables real-time monitoring of the concrete, stressing could be carried out as soon as the designated strength was reached on site. This reduced waiting time, site labour and allowed CCL to optimise the construction schedule while ensuring the integrity of the concrete was maintained.

Usual practice is to cast test specimens for each element and subject these to compression tests in an external laboratory then wait for test results to confirm the correct concrete strength has been reached before stressing can begin.

After construction of the 41-storey Medore building in began in 2010, it was halted at level seven. CCL was called in last year because the client wished to make major architectural changes and complete floors 8 to 39 using post-tensioning.

After determining the need for repair and strengthening of the existing columns and slabs, CCL carried out the work using and steel column jacketing, external and . The company then installed post-tensioned slabs on floors 8 to 39.
