The Civil Engineering Contractors Association was established in November 1996 at the request of contractors to represent the interests of civil engineering contractors registered in the UK as well as to provide a full range of services to members. CECA promotes the positive contribution that the civil engineering industry makes to the nation. The Industry is an integral part of the economy and CECA members construct and maintain national infrastructure which is fundamental to both the social and economic needs of the country. CECA’s current membership is in excess of 350 civil engineering companies which range in size from large and well-known national names to the medium and smaller sized company which may operate at a more regional level. CECA members account for 75-80% of the civil engineering workload undertaken in Great Britain. Britain's civil engineering contractors employ around a quarter of a million personnel, from civil engineers and other construction professionals to general operatives. Well over 100,000 others are engaged in producing the materials and products that are incorporated in civil engineering works. They account for close to a fifth of all construction output, with the annual value of their works rising towards £20 billion.
