When a study is conducted on materials, systems, equipment and accessories it is commonly known as:

• A. Substitution Study
• B. Value Engineering Study
• C. Quality Assurance Study
• D. Materials Audit

Answer: (A)

In construction management, a substitution study is the analysis used to evaluate alternative materials, systems, equipment, and accessories that could replace existing ones. The goal is to achieve the required function and performance at lower cost or with greater value while still meeting durability, safety, and compatibility criteria. This makes substitution study the best fit for describing a focused look at possible replacements across the project scope. Value engineering is broader, encompassing function improvement and overall cost reduction, not just evaluating substitutes. Quality assurance studies concentrate on ensuring processes and outputs meet quality standards, not on identifying replacement options. A materials audit centers on verifying materials, quantities, and compliance rather than exploring substitutions.
