Future development of production sites in the motor industry require an integrated approach for design and realization of the building construction works as well as co-ordination with the produc- tion process to find on one side a feasible solution for the building construction and to allow on the other side minimized disturbance of the plant production out-put. If the plant is located in the inner districts of a city, the task will be complicated by taking the boundary conditions of the adjacent areas into account. To develop the answer which fits the needs of the plant management best, it is necessary to start the basic design considerations with a survey of the existing building, sufficiently deep to elaborate all necessary information, especially concerning material qualities, geometrical dimensions, actual loading conditions etc. Based on these, the structural concept chosen has to go beyond the usual measures taken in many aspects. For example techniques like incremental launch- ing, well known from bridge construction, soil improvement by jet-grouting, the application of mono-piles for transferring the loads to deeper situated soil-layers or gluing for the application of strengthening elements are used. Another aspect of the design exercise follows from fire-resistance considerations. Modified regulations or/and a changed profile of use may yield to a new assessment of the structural qualities when exposed to fire. This can only be done by adopting modern calcula- tion and design methods. It is worth to mention, that especially for a successful implementation of the soil-improvement-strategies, for the development of innovative connection devices and for the fire-resistance design, a complete coverage of the on-site-work by independent experts, if necessary accompanied with measurements and testing, is fundamental.
