The RIBA Plan of Work: Eight Key Project Stages Explained (2024)

The RIBA Plan of Work 2013 is published by the Royal Institute of British Architects. It also endorsed by the Chartered Institute of Architectural Technologists, the Royal Incorporation of Architects in Scotland, the Royal Society of Architect in Wales, the Royal Society of Ulster Architects and the Construction Industry Council.

The RIBA Plan of Work organises the process of briefing, designing, constructing and operating building projects into eight key project stages, detailing the tasks and outputs required at each stage.

It was first available in 1963 as a fold out sheet demonstrating the roles of participants in design and construction in the format of a simple matrix. It has evolved through its history to reflect the increasing complexity of projects, ever-changing regulatory requirements and industry demands, and government criticism. The latest version has moved online as a downloadable PDF and has become far more flexible, with stages such as procurement and planning permission being movable and matters surrounding BIM and sustainability coming into consideration.

NOVO are regularly appointed to carry out consultancy and design of the mechanical and electrical services involved in various projects, often at the Stage 4 Technical Design level of the RIBA Plan of Work. The plan provides universal milestones, allowing us to better communicate our progress with our clients and subcontractors.

The eight key stages of the Plan of Work are detailed below.

Stage 0: Strategic Definition

During this first stage, the client’s business case, strategic brief and other core project requirements are identified. Initial considerations are made for assembling the project team. The Project Programme is established after a review of several sites. The consultants, in collaboration with the client, can properly define the scope for a project and the Preparation and Briefing process can then begin.

Stage 1: Preparation and Brief

In order to maximise the productivity of Stage 2 Concept Design, several parallel and significant activities need to be carried out throughout Stage 1.

This includes the development of the initial Project Brief and any related feasibility studies. The Project Team is assembled, and each party’s roles are defined. When preparing the initial Project Brief, it is necessary to consider the desired project outcomes (potentially derived following feedback from earlier and similar projects), the project’s budget, and the site itself (by undertaking site appraisals and collating site information).

A project risk assessment is required at this stage, and the procurement strategy and Project Programme should be developed.

Stage 2: Concept Design

The Concept Design represents the design team’s initial response to the project brief. Throughout Stage 2, the initial Concept Design is produced in line with the requirements of the initial Project Brief. The Project Team develops a number of Project Strategies including the sustainability, maintenance, operational and handover strategies. These strategies consider post-occupancy and operational issues along with the consideration of buildability. Third party consultants are essential at this stage. The brief is revisited, updated and issued as the Final Project Brief, as part of the Information Exchange at the end of Stage 2.

Stage 3: Developed Design

Concept Design is further developed, and the design work of the core designers is progressed. By the end of Stage 3, the architectural, building services and structural engineering designs will all have been developed and will have been checked by the lead designer. The Cost Information is to be aligned to the Project Budget.

Project Strategies that were prepared in Stage 2 should be developed and detailed, allowing the client to signed them off once the lead designer has checked each strategy and verified that the Cost Information incorporates sufficient allowances.

Stage 4: Technical Design

The lead designer co-ordinates the preparation of the technical design, as this may involve design by specialist subcontractors as well as the client’s core design team. By the end of this stage the architectural, structural and mechanical services design and specifications should describe all main components of the building and how they fit together, and any performance specified work should be defined.

Stage 5: Construction

During this stage, the building is constructed on site in accordance with the Construction Programme. This includes the erection of components that have been fabricated off site. The procurement strategy will have set out the designer’s duties to respond to design queries from site generated in relation to the design.

Stage 6: Handover and Close Out

The project team will facilitate the successful handover of the building in line with the Project Programme and conclude all aspects of the building contract. Other services may be required at this point which will be dictated by the project specific schedules of services. This should be aligned with the procumbent and handover strategies.

Stage 7: In Use

This new stage of the RIBA Plan of Work acknowledges the potential benefits of harnessing the project design information to assist with the successful use and operation of the building.

The RIBA Plan of Work is a comprehensive framework that has been fundamental in guiding architectural and construction projects for years. As an enthusiast in this domain, my expertise lies in the intricate process of project management, design strategies, and the implementation of various stages outlined in this framework.

Let's break down the concepts used in the article:

  1. RIBA Plan of Work 2013: This document, published by the Royal Institute of British Architects, structures the entire lifecycle of a construction project into eight key stages, from initial conceptualization to post-construction use and operation.

  2. Evolution of RIBA Plan of Work: Originally introduced in 1963 as a simple matrix outlining participant roles, it has since evolved to accommodate the complexities of modern projects, adapting to changing regulations, industry demands, and government criticisms.

  3. Key Stages:

    • Stage 0: Strategic Definition: Identifying core project requirements, assembling the project team, and establishing the project program.
    • Stage 1: Preparation and Brief: Developing the project brief, assembling the project team, conducting feasibility studies, risk assessment, and defining roles.
    • Stage 2: Concept Design: Initial response to the project brief, developing strategies (sustainability, maintenance, operational), and revisiting the project brief.
    • Stage 3: Developed Design: Further development of the design, alignment with budget, and preparation of detailed strategies.
    • Stage 4: Technical Design: Coordinating technical design, involving specialist subcontractors, and detailing architectural, structural, and mechanical services design.
    • Stage 5: Construction: On-site construction according to the program, responding to design queries, and following the procurement strategy.
    • Stage 6: Handover and Close Out: Facilitating successful handover, concluding the building contract, and aligning with procurement and handover strategies.
    • Stage 7: In Use: Utilizing project design information for successful building operation and acknowledging post-construction benefits.
  4. Importance of the Plan of Work: It serves as a universal milestone for communication among stakeholders, allowing clear progress tracking and facilitating effective communication with clients and subcontractors.

  5. Role of NOVO: This consultancy firm is regularly engaged in mechanical and electrical services design, often operating at the Stage 4 Technical Design level of the RIBA Plan of Work.

  6. Online Evolution: The latest version has moved online as a downloadable PDF, offering increased flexibility by allowing movable stages like procurement and planning permission and incorporating considerations about BIM (Building Information Modeling) and sustainability.

This structured approach ensures that every aspect of a building project, from its conception to its ongoing use, is meticulously planned and executed, enhancing communication and collaboration across all stakeholders involved.
