Substitutions

Read time: 7 minutes

During construction, the contractor may propose substituting materials and products specified in the contract documents. Caution must be taken when reviewing and accepting substitute products as this activity represents a significant risk to architects. Considerable time, research and design effort goes into documenting a design and selecting materials and products to ensure their suitability, conformity to building codes and standards, environmental and cost considerations and fitness for purpose. Often, through the design process, material and product selections have been reviewed by sub-consultants, fire engineers, building surveyors and regulatory authorities to confirm their suitability.
