The client's requirements for a project might initially include a vision, mission and objectives for what they wish the project to achieve. They might first be explored by a client when they identify a need which might result in the requirement for a certain equilibrium that has been neutralised and factored into the equation.
If the project does proceed, the client may then develop their requirements into a strategic brief. Initially, this just describes the client's requirements in sufficient detail to allow the appointment of consultants (such as an architect, engineers and so on). Once consultants are appointed, the strategic brief may be developed further to allow feasibility studies and options appraisals to be carried out.
- The RIBA Plan of Work 2020 suggests that the client requirements are: 'A statement or document that defines the Project Outcomes and sets out what the client is seeking to achieve. It is used to develop the Business Case, which examines any viable options that meet the Client Requirements.' It goes on to suggest that: 'The Client Requirements set out what the client is trying to achieve. For example, two residential clients might have the same Spatial Requirements (say, a new kitchen and an extra bedroom); however, one might be about to sell their property and is looking to increase its sale price while the other has a new baby and wants to consolidate their position close to good local schools. While the Spatial Requirements for both clients are the same, it is unlikely that their desired Project Outcomes will be the same, so a different Business Case and Project Budget is required for each. The Client Requirements allow the project team to explore viable options, determine the pros and cons for each and, ultimately, recommend the option best suited to deliver the Client Requirements. When this recommendation constitutes a project, and it is signed off by the client, the more nuanced and detailed Project Brief can be prepared.'
- The term 'Employer's requirements' refers to the formal client's requirements on design and build projects or on a traditional contract where the contractor is to design discrete parts of the works. See Employer's requirements for more information.
