I attach considerable importance to the health and efficiency of the UK construction industry. Construction represents 8 per cent. of GDP and employs almost two million people. Construction is central to the delivery and maintenance of the national infrastructure and therefore to all our public service, including health care, transportation, housing and education. The Government's Rethinking Construction initiative aims to work with the industry improve its productivity and competitiveness by addressing issues such as the efficiency of processes and the quality of the end product.
