Every development project must begin with infrastructure design – and professional planning is the key to ensuring a functioning infrastructure. HOCHTIEF Consult's Infrastructure competence center pools this planning expertise to ensure successful implementation of development projects worldwide. In Taiwan, for example, we were responsible for the complete planning of a 42-kilometer high-speed railway section in what was the world's biggest infrastructure project at the time. Our competence center also planned all roadways for aircraft, airport operation, and public access at a new airport in Athens, in addition to being responsible for overall planning management. When it comes to tunnel projects, our planners, designers, geotechnical engineers, and planning coordinators are in great demand worldwide because they combine economy and safety in an ideal manner.
