Success through expertise and competence. Preparing and realising complex construction projects successfully not only requires engineering expertise in all the building trades involved, but also an above-average degree of know-how concerning technical equipment, as well as a maximum of competence when it comes to methodology and public-spirit. The primary causes of problems concerning quality, scheduling and costs will come about after the detailed analyses for structural engineering projects costing far over a billion euros to build, very often due to poor workmanship in technical installations. We have defined one of our most important entrepreneurial challenges as putting a stop to or preventing this.
