New challenges in construction-site logistics of large-scale construction projects are emerging. Along with the classical project goals among timeliness, cost and quality, the reduction of external effects of construction projects on the environment and adjoining residents becomes more and more important. It is the social awareness that forces building owners and investors to action. The impact of the population is multi-layered. On a first level, the permit legislation and plan approval law gives a legal framework for the voice of the population. Investors and building owners have to go through a long inspection and approval procedure in order to commence the construction activities. On a second level, media attention calls for image cultivation. Building owners tend to be willing to do more than is necessary by law. There is a trend towards internalizing external effects, to strive for ecological and urban compatibility and to increase social acceptance of construction projects. This shift of paradigm has vital effects on the construction-site logistics of large-scale construction projects, since logistics can make a considerable contribution to these new challenges. Especially, the bigger a construction project and the more urban the location of building project, the more significant are the effects on the logistics. The happenings around the modernization of Stuttgart's railway station Stuttgart 21 have shown the impact of the public's voice. The Deutsche Bahn has come up with a logistical concept, which almost completely avoids the transportation of the around 6 Million m³ of ground excavation from the city center of Stuttgart by trucks. Instead, the logistical concept makes use of transportation by train. A similar situation around the new building of Potsdamer Platz in Berlin has even made use of river-bound transportation in order to avoid a full congestion of whole city districts. But the effects reach further than the choice of mode of transportation. There is a need of clever logistical concepts that are integrated into early planning phases of projects. The classical approach of leaving the logistics up to the construction company is often outdated. Instead, there is a trend towards centralizing logistical services and integrating specialized logistics service providers from the early stages of a project. As a result, building owners and investors gain more degrees of freedom in the tender structure, as the cross-contractor responsibility of a general contractor often becomes obsolete. Changes affect both, the planning as well as the operative side of logistics. Centralized services when necessary, reach as far as slot control systems for every truck move in the logistical chain. This paper displays two example projects in airport construction site logistics and examines how new challenges are faced today, the new building of the Berlin Brandenburg International airport and the extension of Terminal 1B at Frankfurt airport under traffic operation. It shows how innovation in construction site logistics today is both, organizational and technological. (original abstract)
