How to Evaluate an Alternative Product for a Project
Compare requirements, evidence and differences in one register. Keep sample submission separate from approval for use.
A product that looks similar is not automatically suitable for a project. An alternative-product review should show how the proposed item addresses the current requirements.
Establish the reference
Use the latest specification, drawings and relevant approved material records. A comparison based on an outdated revision can lead to an incorrect conclusion. Our construction material technical-file guide explains the supporting document scope.
Compare requirements individually
List the characteristics defined by the project and identify the proposed product’s response to each one. Reference the supporting document or drawing. Mark missing information as pending rather than assuming compliance.
Build a simple comparison register
- Requirement and source document/revision
- Reference product description
- Proposed alternative and supporting document/page
- Differences or missing information
- Installation, accessory and delivery effects
- Review owner, decision and decision date
These fields form a working template, not a test result or certificate of conformity.
Make differences visible
A difference does not always mean rejection, but it may require review by the responsible project authority. Keep the supplier’s equivalence statement separate from project approval.
Review the wider impact
A substitution may affect accessories, connections, installation methods or delivery sequencing. Show these effects alongside the commercial comparison. Do not present unverified cost or time savings as confirmed outcomes.
Record the decision
Track submission, technical review and approval as distinct stages. Receiving a quotation or submitting a sample does not establish approval for use. See our material-submittal revision guide to keep the decision connected to the correct product and version.
