What determines the type of materials or methods used in construction?

The type of materials or methods used in construction is primarily determined by specifications. Specifications provide detailed descriptions of the materials, standards, and performative qualities required for a construction project. They outline exactly what materials are needed, their various characteristics, and the processes that must be followed to ensure the desired quality, safety, and performance of the completed structure.

Specifications form a crucial part of the construction contract and help to ensure that all parties involved have a clear understanding of what is expected. They serve as a guideline for architects, engineers, contractors, and suppliers, ensuring that everyone is aligned on the materials and construction techniques to be employed.

While building codes establish minimum safety standards that must be adhered to, they do not dictate the specific materials or methods like specifications do. References and UL (Underwriters Laboratories) certifications serve to provide additional guidance or validation but do not play the central role in determining the types of materials or construction methods required for a project as specifications do.
