Installation of the electrotechnical systems to be supplied
The project involves the construction of the new Integrated Regional Control Center South (IRLS Süd) with the associated outdoor facilities on the Teichkoppel 21 site in Bad Oldesloe. The project comprises a two-story main building with control center area and administration wing as well as staff, technical and other functional rooms, plus a one-story, unheated technical annex with integrated radio mast, and an access-secured outdoor area. The site area is 8,740m². The supporting structure is planned as a solid steel-concrete skeleton with an infill of lightweight concrete masonry. The staircases will be of StB construction. The roof construction will be realized as a lightweight structure in timber construction. The building project has a gross floor area of approx. 3,460m². The building will be supplied with drinking water by the municipal drinking water network and with hot water by means of central hot water generation (fresh water station). The heat supply is ensured by a gas condensing boiler as peak load generator and a brine/water heat pump as base load generator.
