Production information

The Construction Project Information Committee (CPIC) defines production information as '...the information prepared by designers, which is passed to a construction team to enable a project to be constructed'.

(Ref. CPIC The importance of production information - The Construction Project Information Committee provides best practice guidance on the preparation of production information.)

Production information is incorporated into tender documentation and then the contract documents.

The quality of production information is extremely important. Unless it is prepared and co-ordinated properly, there will be disputes and delays on site, and costs will be incurred.

Responsibility for production information depends on the selected system of procurement and the chosen form of contract.

On traditional contracts (and management contracts and construction management contracts), production information may be produced by the consultant team, on behalf of the client. Some elements of production information may be produced by specialist contractors, co-ordinated by the lead designer. Any gaps in this information that require specialist input after the tender process should be clearly defined showing abutment details to adjacent work faces and how such work is integrated into the overall scheme.

On other forms of contract (such as design and build or private finance initiative projects), responsibility for preparing production information and co-ordinating information prepared by specialist contractors may lie with the main contractor.

Production information may include:

There should be a particular emphasis on equipment with long manufacturing times, such as switchgear, chiller units, lifts, escalators or bespoke cladding systems, and on front-end construction such as service diversions, demolition, setting out details, underground drainage, piling and groundworks.

Definitions and rules relating to drawn information for 'with quantities' projects are described the New Rules of Measurement. See New Rules of Measurement for more information.

Increasingly, software is used to prepare elements of production information such as computer aided design (CAD) to prepare drawings, common data environments (CDE), and proprietary systems for the preparation of specifications.

The advent of building information modelling (BIM) can allow the automatic generation of all elements of production information from a single co-ordinated model, resulting in a reduction in errors and so costs.
