The rate of serious work-related injuries compensated in the building and civil engineering industry is more than twice the average. The rate of approved work-related diseases is five times the average (Larsson et al., 2011). The most frequent types of occupational accidents on building and civil engineering sites are losing control or a person falling, either from a height or on the same level. Two-thirds of the reported occupational diseases are to the musculoskeletal system, resulting from excessive workload (AFA Insurance, 2011; Byggindustrins Centrala Arbetsmiljöråd, 2010; Swedish Work Environment Authority, 2011). Furthermore, accident analyses show that the design of the building influences the construction safety (Behm, 2005; Gambatese et al., 2008; Haslam et al., 2005).
