A benchmark is defined as a known elevation that serves as a reference point for measuring land or site conditions. In construction and surveying, benchmarks are critical as they provide a standard point from which other elevations can be determined. They are typically established with great accuracy and are permanently marked for future use. This is particularly important in ensuring that all elevations on a construction project are consistent and aligned with this reference, which helps in avoiding errors related to height discrepancies.

In contrast, the other options refer to different aspects of project management and construction processes. A scheduled progress goal relates to the timeline of the project; the start time and date pertains to project initiation; and the standard for construction site productivity evaluates how efficiently work is being performed. These elements are vital for successful project management but do not define what a benchmark is in the context of elevation and surveying.
