Nowadays, Information and Communication Technology (ICT) has already brought significant cost savings to several industries. During the construction of a building, modifications may require costly on-site visits of engineers to adapt plans to the new circumstances. ICT such as video conferencing systems may reduce the number of these visits significantly. Video conferencing enables the engineers to remain in the office. But nevertheless they can comprehend any problems and particularities of the complex new situation, adapt their planning, and then instruct the workers on-site. Unfortunately, in-building communication networks, as well as electric installations, are set up very late in the building construction process. In addition, communication over cellular mobile networks (GSM/UMTS) is often not possible inside buildings, especially in basements.
