Which statement best describes a Construction Survey?

• A. Determining property boundaries for mortgage purposes
• B. Measuring quantities for earthwork
• C. Locating floodplains
• D. Controlling elevation, horizontal position, dimensions, and stakeout of line and grade for construction

Answer: (D)

Construction surveying is about laying out a project on the ground so it’s built exactly where and how the design specifies. It revolves around controlling where things sit (horizontal position), how high or low they are (elevation), and the exact dimensions, with stakeouts that mark the line and grade for construction crews to follow. That makes the statement about controlling elevation, horizontal position, dimensions, and stakeout of line and grade for construction the best fit because it directly describes the on-site layout and guidance role of a construction survey.

The other activities described—determining property boundaries for mortgage purposes, measuring quantities for earthwork, and locating floodplains—are important surveying tasks, but they serve boundary determination, quantity takeoff, and land-use mapping rather than the on-site layout and staking that define construction surveying.
