The construction output statistics are derived from the Quarterly Construction Enquiry (QCE). This is a sample survey carried out by NISRA on 700 Northern Ireland firms in the construction industry each quarter. In addition, public bodies carrying out construction work directly are also included within the scope of the survey. This includes the likes of Roads Service and the Northern Ireland Housing Executive.
