What is a key component of the project manual in relation to specifications?

The project manual is an essential document in the context of construction and engineering projects, and its primary function is to encompass the written requirements for the project. This includes detailed specifications that describe the materials, workmanship, and standards necessary for the successful completion of the project.

By systematically outlining these requirements, the project manual serves as a critical reference for contractors, architects, and engineers involved in the project. It ensures that everyone is on the same page regarding what is expected, which helps to maintain quality and consistency throughout the construction process. The specifications included are vital for assessing compliance and evaluating bids from contractors, making option B the correct choice.
