When estimating, what is the term for the amount of information an estimator needs?

The term that reflects the amount of information an estimator needs when estimating is insight. Insight in this context refers to a deep understanding and awareness of the project requirements, materials, costs, and processes involved. This enables the estimator to make informed decisions and accurate assessments about the quantities, labor, and materials required for a construction project. The estimator's ability to gather and analyze this information critically influences the accuracy of their estimates.

In construction, clarity, while important, generally pertains to how understandable the information is rather than the quantity of information. Details, although relevant, refer more to specific elements that contribute to the overall understanding but do not encapsulate the broader comprehension needed. Specifications define the requirements of a project but do not inherently describe the estimator's need for a comprehensive foundation of information, which is captured by the term insight.
