1 2 Detailed floor plans and logistics concepts are developed for each construction site to ensure that they operate as smoothly as possible. Where possible, sites receive supplies and dispose of their waste by rail or waterway. We also check whether it is worthwhile using a static con- crete mixing plant, with the aim of reducing traffic. Special rubble collection points ensure that waste is separated right from the construction phase. Resources are conserved by means of reusable system formworks. Enclosed construction equipment is used to cut noise and protect residents and workers on the site during the construction period. 2 1 Sustainable? We always have been!
