The construction sector is one of Europe's biggest industries, representing some 10% of GDP and 50,5% of Gross fixed Capital formation. It employs more than 12 million EU citizens and it is estimated that 26 million workers in the European Union depend in one way or another, on the construction sector.

The construction sector in CEN covers more than 3000 work items on product standards and test methods (for use in building and civil engineering). Of these, about 600 standards started to be prepared under the Construction Products Directive (CPD) and are or will be harmonized under the Construction Products Regulation (CPR), along with about 1500 supporting standards (test methods).
