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'.
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:
- Drawings (location drawings, component drawings and dimensioned diagrams).
- Specifications, design criteria and calculations (specification information can be included on drawings or in a separate specification, but information should not be duplicated as this can become contradictory and may cause confusion).
- Bills of quantities or schedules of work (schedules of work are 'without quantities' instructional specifications often produced by designers on smaller projects for pricing, or for items such as builders work and fixing schedules, such as sanitary fittings, doors, windows, ironmongery, light fittings, louvers, roller shutters, diffusers, grilles and manholes).
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.
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.
