What do specifications in construction define?

Specifications in construction serve a crucial role by detailing the quality of work and the materials that must be used throughout a project. They provide precise instructions on how various components of a project should be constructed, including specific performance standards and the appropriate materials that meet those standards. This ensures that the finished structure meets both safety and functionality criteria, and compliance with local building codes and regulations.

While timelines, architectural styles, and cost estimations are important aspects of construction projects, they fall outside the main purpose of specifications. Specifications focus specifically on the "how" and "what" of construction, ensuring that any work performed aligns with the required standards and delivers the intended quality. This forms a key basis for contracts and helps maintain communication between architects, engineers, contractors, and suppliers throughout the project.
