Production of estimates of Construction New Orders
New Orders is a monthly series of new contracts and orders for new building,
renovation or alteration work placed by clients outside the construction industry. Press
notices are published on the first Thursday of the month, except where this would
clash with the publication of Output, when it becomes the second Thursday of the
New Orders figures include:
All new contracts and orders for new construction work or renovations and
alterations work obtained in the month from clients and contractors outside the
Extensions to existing contract orders;
The value of new construction work to be done during the contract on serial, run-on
or measured term contracts and package deals;
New construction to be undertaken at the contractor’s own initiative;
Total value of contracts where the responder is the appointed management
The following are excluded:
Contracts for repair and maintenance;
Sub-contracts awarded by other contractors in the construction industry;
Constricts obtained from management contractors;
Additional costs for work in an existing contract, eg on variation of price contracts.
Sampling and collection of all New Orders information.
The monthly construction new orders information for Great Britain is based on
monthly returns from a sample of around 5,500 firms taken from the New Orders
universe of around 27,000 construction contractors. This universe is kept up-to-date
through quarterly exchanges of information with the Inter-Departmental Business
Register as well as information from data suppliers.
Construction firms on CISTATS (our bespoke statistical software package) are
assigned to value groups (VGs) based on their annual level of new work, which are
used to produce a stratified rotational sample, with a rotation period of 24 months.
Rotational sampling is explained in Appendix A. The table below shows the value
groups (or “strata”) and the sampling ratios used:
