A topographic survey makes it possible to understand the land with specific data before design or construction. It is a technical basis for architecture, engineering, and construction.
It may include elevations, levels, contour lines, profiles, sections, existing structures, apparent boundaries, relevant elements, and digital terrain models.
What it is for
It helps define design levels, earthworks, site placement, drainage, access, and construction decisions.
Deliverables
The deliverable may be a topographic plan, digital file, report, profiles, sections, or data prepared for the technical team.
