Design-und-Build-Projekt: Planung und Bau einer Messwarte mit Laborgebäude

Design-and-Build Project: Design and construction of a control room with laboratory

Design and build contracts are of particular interest for clients if tight schedule requirements for the completion and commissioning of buildings have to be considered and the projects have a high level of complexity. With these preconditions clients rather decide to award separate planning, procurement and construction processes with all necessary interface coordination to one contractor for reasons of efficiency. BASF SE has awarded a design and build contract to HOCHTIEF Building GmbH for a three-storey control room building with laboratory for a new production plant of toluoldiisocyanat (TDI) at the main BASF site in Ludwighafen, Germany. The planning was performed by the department Consult IKS Energy of the HOCHTIEF Engineering GmbH in Frankfurt. The scope of planning included partially the design engineering and the approval planning as well as the full detail planning for all disciplines (architectural planning, structural and façade engineering, building physics, HVAC engineering and laboratory planning). Furthermore, the reinforced concrete structure built on a pile foundation had to be designed blast wave resistant. In addition the requirement for gas tightness had to be considered in the building design, including the execution of an internal air supply in the case of emergency.
