A system to test the ground surface conditions of construction sites-for safe and efficient work without physical strain

摘要

Ground surface conditions on construction sites have an important influence on the health and safety of workers and their productivity. The development of an expert-based 'working conditions evaluation' system is described, intended to assist site managers in recognising unsatisfactory ground conditions and remedying these. The system was evaluated in the period 2002-2003. The evaluation shows that companies recognize poor soil/ground conditions as problematic, but are not aware of the specific physical workload hazards. The developed methods allow assessment of the ground surface quality and selection of appropriate measures for improvement. However, barriers exist at present to wide implementation of the system across the industry. Most significant of these is that responsibility for a site's condition is not clearly located within contracting arrangements, nor is it a topic of serious negotiation.
