Which practice is typical for construction surveys?

• A. Construction surveys (layout, as-built, quantity)
• B. Topographic surveys
• C. Cadastral surveys
• D. Environmental surveys

Answer: (A)

Construction surveys focus on what happens on the job site to guide the build and verify what is actually built. They involve layout and staking to position features exactly where the design specifies, as-built measurements to record the finished locations and dimensions, and quantity measurements to estimate earthwork and other material needs. This combination is what keeps a construction project progressing accurately and recorded against the plans, from initial setting out to final as-built documentation and material quantification. Other survey types serve different stages or purposes: topographic surveys map the terrain for design, cadastral surveys define property boundaries, and environmental surveys address environmental conditions and compliance. So, the typical practice during construction is the construction surveys that cover layout, as-built, and quantity.
