What document provides detailed information about materials and methods of construction?

The correct answer is specifications. Specifications are critical documents that outline the specific requirements for the materials, workmanship, quality, and performance of a construction project. They provide detailed descriptions of the materials to be used, the methods of construction to be followed, and the standards that must be adhered to throughout the process. This level of detail is essential for ensuring that all parties involved in the project have a clear and consistent understanding of what is expected, which plays a significant role in the successful execution and completion of the project.

Blueprints typically refer to the architectural drawings or plans that visually represent the layout of the project, including dimensions and placements of structures. While blueprints are essential, they do not typically include all the detailed specifications about materials and methods.

Work orders are documents that instruct workers to perform specific tasks but do not provide comprehensive guidelines on materials or construction methods.

Site plans are a representation of the property's layout, showing the placement of buildings and other structures within a specified area but are lacking in the detailed instructions found in specifications regarding construction methods and materials.

Thus, specifications serve as the backbone of construction documentation, delineating the necessary details that ensure projects are executed correctly.
