DESIGN PROCESS
requirements. Certification and classification reports, demonstrating tested performance meeting the project brief, should be obtained by the designer for any specified products and systems. Planning applications are usually made in stage 3. A fire statement should be submitted for applicable buildings in accordance with Gateway 1 planning requirements. This should include a description of the proposed construction and fire performance requirements. Some stage 3 functions are now being undertaken in stage 2 to provide a firm technical base for the concept design and to develop the early-stage fire strategy.
calculations (such as resistance to wind load), installation details and any additional information required by the employer’s requirements.
RIBA STAGE 6 – HANDOVER
Manufacturers’ technical departments should be consulted at the earliest opportunity to obtain copies of all evidence required to be
handed to the building owners as part of the Regulatory Reform (Fire Safety) Order (RRFSO) and Regulation 38.
RIBA STAGE 7 – USE
RIBA STAGE 4 – TECHNICAL DESIGN
In the majority of projects, the design team and construction team will have no stage 7 duties to undertake. The Plan of Work also

inform how far the designers take the design and what design completions are undertaken by the contractor. If a contractor has been appointed at this stage, early discussions with specialist subcontract installers can commence. A submission for Building Regulations approval should include either performance or proprietary specification for through-wall and include certification and classification reports for specified systems. Once the Building Safety Act is implemented, Gateway 2 requirements must be complied with for applicable buildings. Through- wall infill SFS is a series of components that, when tested together and installed as tested, can provide evidence of fire performance. There should be no substitution of components without the system owner’s written approval.
RIBA STAGE 5 – MANUFACTURING AND CONSTRUCTION
CDP is typically applied to the through-wall package, or to the SFS package when through-wall elements are procured separately. The contractor submits
verification of the system selected, any
