CPV code 71313410 designates Risk or hazard assessment for construction in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
71313410 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 71313400 (Environmental impact assessment for construction).
