Approved equal
In the UK construction industry, the term "Approved Equal" refers to a product, material, or equipment that is not specifically listed or named in the contract documents (such as specifications or drawings) but is considered acceptable as a substitute because it meets the specified performance and quality criteria. It is a mechanism that allows for flexibility in the selection of materials and products, provided that they meet the required standards and receive the necessary approvals. This term ensures that alternatives can be considered without compromising the quality or performance of the construction project.
- The "Approved Equal" must comply with the performance specifications, standards, and quality levels outlined in the contract documents. It should provide the same functionality, durability, and performance as the specified item.
- The contractor or supplier proposing an "Approved Equal" must seek approval from the project’s architect, engineer, or client representative. This usually involves submitting technical data, certifications, and possibly samples for review.
- The approval process considers various factors, including technical performance, compatibility with other components, aesthetics, lifecycle costs, and any impact on the construction schedule.
- Substituting with an "Approved Equal" should not increase the project's overall cost unless agreed upon by all parties. If the substitution leads to cost savings, these may be shared according to the contract terms.
- The use of an "Approved Equal" must be formally documented in the project records. This often involves written approval or a change order, ensuring that there is a clear and traceable record of the decision.
- The responsibility for ensuring that the "Approved Equal" meets the required standards typically falls on the contractor. Any risks associated with the substitution, such as potential defects or failures, may also rest with the contractor unless otherwise agreed.
- The concept of "Approved Equal" provides flexibility in procurement, allowing contractors to propose alternative products that might be more readily available, cost-effective, or innovative while still meeting project requirements.
