Collapsing scaffolds pose a constant danger in today’s construction industry and can result in serious injuries and substantial financial losses. To avoid the occurrence of such incidents on scaffold structures, a solution based on technological brokering between scaffolding and a wireless sensor network was evaluated on technological and market based feasibility. Interviews revealed the wall anchoring of scaffolds as a weak spot, which frequently fails as a consequence of human errors. As a result, several sensor types where examined on their suitability as an automated early warning system for wall fixings. Data from the interviews was analysed and suggested only a moderate marked feasibility, due to limited financial possibilities and modest innovation willingness within the scaffolding industry. The most promising design consists of either an accelerometer or strain gage, but low output signals, high noise levels and limited space make the system challenging and require extensive testing. Thus, the technological feasibility was found to be relatively low with several uncertainties when considering the requirements on simplicity, reliability, low time consumption and costs.
