Frankfurt Airport will be expanded through the construction of a new rail link and an additional passenger terminal. The combination of a variety of factors, namely the former US airbase no longer being used for military purposes, the introduction of larger aircraft such as the A380, and the optimization of electronic landing systems, means that the land-side passenger capacity can be increased beforehand. In 2004, with a view to taking advantage of this land-side opportunity, Fraport AG tasked AS+P and Dutch company NACO Airport Consultancy and Engineering, based in The Hague, with forming a working party to conduct a capacity analysis and plan the development of the terminal.
The studies aimed to identify capacity bottlenecks and develop measures to eliminate them. AS+P was responsible for examining the structural aspect of the measures. The result: a modular concept comprising individual measures which can be implemented independently of one another. They range from reorganizing operational procedures to conducting alteration work on sections of the terminals. As the project progressed, the focus turned to ensuring the terminal was capable of handling the Airbus 380, which was expected to go into operation out of Frankfurt as of 2006. To this end initial positioning concepts drawn up by Fraport AG were subjected to verification, and the feasibility of the project and its impact on both air and land-sides assessed. On this basis, the project specified initial tasks, the costs involved, and the needed time. In the process NACO and AS+P compiled functional drafts for sections A, B, and C of Terminal 1, as well as all of Terminal 2, including bridges and baggage areas.
