AZCM provided complete package of construction management services to its client – the Norwegian property development company Schage Real Estate. The project involves over 40,000 sq m of office and retail space, a 30,000 sq m three-story underground parking garage, more than 50 different contractors, subcontractors, suppliers and vendors, hundreds of workers on-site every day, the newest and most advanced construction, technical and technology solutions. The construction of an office building of such size and complexity has not been seen before in Lithuania.
The main, eastern 17-story tower rests on a concrete slab, which was poured using 3,000 cubic meters of concrete. Such a unique and very complex building structure was used for the first time in Lithuania. As designed by Norwegian architects, part of the 17-story East building above the third floor is biased and "suspended" above the ground, creating an impression that 3 bottom floors are supporting the 14 top floors. For the load-bearing purposes and in order to accomplish this architectural feature, a gigantic custom-made 220-ton steel truss had to be installed.
Moreover, the same type of 220-ton steel truss is also used to build the 12-story North building of Quadrum Business City.
It took 5 days just to assemble 40 truckloads of component parts shipped from neighboring Latvia to build a 750 ton lifting capacity crane, which was used for installation of one of these megastructures.
Because this was the first time such a construction solution was used in Lithuania, we had to be extremely precise, accurate and detailed in planning the work and logistics. We constantly improved our knowledge and expertise on this unique solution to ensure highly professional and precise process management.
Also unique in Lithuania was the use of monolithic cavity-type floor slabs fabricated using plastic "bubbles". They take up a certain volume inside the slab, reducing the amount of concrete required as well as the weight of the structure.
Other construction solutions that are still new or uncommon in Lithuania are also being utilized in building Quadrum. They include exposed concrete, tight wire rope and a unique foundation slab, which was poured using 3,000 cubic meters of concrete.
