Design and build: production information
The production information stage is concerned with preparing the information the contractor will need to construct the project. It should also include the completion of applications for statutory approvals.
 Starting the work stage.
The contractor co-ordinates a start-up meeting to receive feedback from the previous stage and agree the programme for the preparation of production information along with its format, identification of any work packages, sequencing and co-ordination procedures, including co-ordinating and integrating information from specialist contractors.
There should be a particular emphasis on equipment with long manufacturing times such as switchgear, chiller units, lifts, escalators and bespoke cladding systems, some of which may justify early ordering as well as booking piling rigs. Front-end construction work such as site exploration, service diversions, demolition, setting out, underground drainage, decontamination, site clearance piling and groundworks may merit placing of preliminary contracts.
The client and contractor should consider the need to appoint rights of light surveyors and party wall surveyor(s) and to serve party wall notices, if this has not been done. In addition, the client may identify a requirement to appoint additional independent client advisers if the consultant team has been novated or switched to the contractor.
 Preparing production information and completing statutory approvals.
The contractor prepares a schedule of production information that is requried, including responsibilities for its preparation, a programme for its preparation and a document control system for revision control.
The contractor co-ordinates:
- The preparation and integration of production information.
- The preparation of schedules of inspections and tests, mock-ups and samples.
- The preparation of a draft building user's guide and a building log book.
- Development of the client's site waste management plan (if there is one).
- The establishment of quality control systems and setting out criteria.
- Outstanding information needed for building regulations and other statutory approvals (such as negotiations with the Highways England, structural calculations, CO2 emission rates and a list of specifications used in the CO2 emission rates calculations) which must be submitted before works start on site.
If required by the employer's requirements, the contractor prepares contractor's design documents (such as a production information report) for the client describing production information, including any remaining components, assemblies, specialist items, samples or materials for comment by client.
The client considers the contractor's design documents and comments within the specified time, either accepting, making comments or rejecting the contractor's design documents. This can only be done in relation to compliance with the employer's requirements. The client should be wary of 'approving' contractor proposals as this might be deemed to relieve the contractor of their liability for those items.
