01Start with the outcome, not the catalogue
Describe what the project needs to do before naming a product. Capacity, weather protection, access, durability, operating pattern, visual intent and programme constraints are usually more useful starting points than a preferred model number.
This leaves room to identify the right system while preserving the requirements that actually matter to the architect, developer, council or operator.
02Separate fixed requirements from preferences
A brief becomes easier to price and review when non-negotiable requirements are clearly distinguished from preferences. Dimensions, site exposure, accessibility, structural interfaces and required documentation may be fixed; colour, accessory packages or control options may still be open.
That distinction prevents optional features from being treated as compliance requirements and stops critical constraints from being lost inside a long wish list.
03Define the interfaces
Most project-product problems occur at interfaces: structure to façade, roof to drainage, equipment to power, pool to foundation, court surface to substrate, or modular building to local services.
The brief should identify what the supplied system connects to and which party is responsible for designing, verifying and constructing each adjoining element.
04Ask for evidence that matches the claim
Certificates, test reports, drawings and technical data are useful only when they relate to the selected product or configuration. A generic factory certificate should not be treated as evidence for a project-specific structural, fire, wind or durability claim.
List the documents the project team actually needs and identify which requirements remain subject to destination-specific engineering or approval.
05Keep supply scope and local works visible
Supply-only projects work best when foundations, installation, electrical work, drainage, lifting, site preparation, local engineering and statutory approvals are shown as separate scopes unless expressly included.
Clear scope boundaries are not exclusions hidden in fine print; they are part of making the project buildable and the quotation comparable.
06Design the brief for change
Projects evolve. A useful brief records what is approved, what is provisional and what can still change without forcing a full redesign. It also identifies future expansion, enclosure, accessories or additional phases that may affect today's interfaces.
This is particularly valuable for staged sports facilities, outdoor rooms, modular developments and repeat procurement programmes.
07Finish with a decision record
When the product pathway is selected, retain the assumptions, verified dimensions, agreed options, evidence set, exclusions and local responsibilities alongside the final quotation or submittal.
That decision record becomes the bridge between early research, specification, procurement and the team that eventually receives or installs the supplied system.
