The process for completing the design and construction of a building is often divided into notional ‘stages’. This can be helpful in establishing milestones for the submission of progress reports, the preparation of information for approval, client gateways, and for making payments. However there is a great deal of ambiguity between the naming of stages by different organisations and the definition of what individual stages include (see comparison of work stages) and so it is important that appointment documents make it clear specifically what activities fall within which stage, and what level of detail is required.
‘In use’ is a new phrase coined by the Royal Institute of British Architects (RIBA) for the 2013 Plan of Work. This plan comprises eight work stages, and its new terminology, stage referencing system and lack of detail have generated some criticism.
- 0 - Strategic definition.
- 1 - Preparation and brief.
- 2 - Concept design.
- 3 - Developed design.
- 4 - Technical design.
- 5 - Construction.
- 6 - Handover and close out.
- 7 - In use.
Stage 7, ‘In Use’ is described by the RIBA as a new stage within the Plan of Work which includes post-occupancy evaluation and post-project review as well as ‘…new duties that can be undertaken during the In Use period of a building.’
- Energy consumption and energy certificates.
- Tenants queries.
- Facilities management.
- The preparation of tender documents for maintenance and operation contracts.
The RIBA suggest that whilst the building's ‘end of life’ might be considered during this stage, it is more likely to be part of Stage 0 for a new project.
