This study is intended to support the REFIT Sectoral Fitness Check of the Construction Sector, undertaken by the European Commission and expected to be published in the spring of 2017. The Sectoral Fitness Check aims at examining how various EU legal acts impact on the construction sector, and at identifying possible areas of improvement, including reduction of regulatory costs and burdens and a better alignment of provisions, if applicable. The analysis included evaluating the efficiency, coherence, effectiveness, relevance and EU added value of most relevant provisions of EU legislation, with respect to the objectives for a more competitive and sustainable construction sector, in particular for SMEs. Particular attention was paid to identifying any synergy or inefficiencies arising from these acts
