  40. 40. A E The RIBA Plan of Work organises the process of briefing,designing,delivering, maintaining,operating and using a building into eight stages. It is a framework for all disciplines on construction projects and should be used solely as guidance for the preparation of detailed professional services and building contracts. 0 Strategic Definition 1 Preparation and Briefing 2 Concept Design 3 Spatial Coordination 4 Technical Design 5 Manufacturing and Construction 6 Handover 7 Use Projects span from Stage 1 to Stage 6; the outcome of Stage 0 may be the decision to initiate a project and Stage 7covers the ongoing use of the building. Stage Outcome at the end of the stage The best means of achieving the Client Requirements confirmed If the outcome determines that a building is the best means of achieving the Client Requirements, the client proceeds to Stage 1 Project Brief approved by the client and confirmed that it can be accommodated on the site Architectural Concept approved by the client and aligned to the Project Brief The brief remains “live” during Stage 2 and is derogated in response to the Architectural Concept Architectural and engineering information Spatially Coordinated All design information required to manufacture and construct the project completed Stage 4 will overlap with Stage 5 on most projects Manufacturing,construction and Commissioning completed There is no design work in Stage 5 other than responding to Site Queries Building handed over, Aftercare initiated and Building Contract concluded Building used,operated and maintained efficiently Stage 7starts concurrently with Stage 6 and lasts for the life of the building Core Tasks during the stage Project Strategies might include: – Conservation (if applicable) – Cost – Fire Safety – Health and Safety – Inclusive Design – Planning – Plan for Use – Procurement – Sustainability See RIBA Plan of Work 2020 Overview for detailed guidance on Project Strategies Prepare Client Requirements Develop Business Case for feasible options including review of Project Risks and Project Budget Ratify option that best delivers Client Requirements Review Feedback from previous projects Undertake Site Appraisals No design team required for Stages 0 and 1. Client advisers may be appointed to the client team to provide strategic advice and design thinking before Stage 2 commences.

Further guidance and detailed stage descriptions are included in the RIBA Plan of Work 2020 Overview. © RIBA 2020 Stage Boundaries: Stages 0-4 will generally be undertaken one after the other. Stages 4 and 5 will overlap in the Project Programme for most projects. Stage 5 commences when the contractor takes possession of the site and finishes at Practical Completion. Stage 6 starts with the handover of the building to the client immediately after Practical Completion and finishes at the end of the Defects Liability Period. Stage 7starts concurrently with Stage 6 and lasts for the life of the building. Planning Note: Planning Applications are generally submitted at the end of Stage 3 and should only be submitted earlier when the threshold of information required has been met. If a Planning Application is made during Stage 3,a mid- stage gateway should be determined and it should be clear to the project team which tasks and deliverables will be required. See Overview guidance. Procurement: The RIBA Plan of Work is procurement neutral – See Overview guidance for a detailed description of how each stage might be adjusted to accommodate the requirements of the Procurement Strategy.
