Topographic Survey Drafting

High-accuracy elevation mapping, contour interpolation, surface feature layouts, and downstream integration.

Topographic Survey Drafting

TOPOGRAPHIC DRAFTING & SURFACE INTERPOLATION

A topographic survey is the foundation that engineers, architects, and planners build on, so accuracy in the contours and surface data matters as much as accuracy in the boundary. ArcusCAD turns elevation shots, breaklines, and surface data into topographic drawings your engineering team can design from immediately, whether the project involves a small residential lot or a large commercial site with complex grading needs.

We pay close attention to how contours interpolate around structures, drainage paths, and site features so the finished drawing reflects the real conditions on the ground rather than a rough approximation. Because topo surveys often feed directly into grading, drainage, and utility design, we build every drawing with the next phase of the project in mind.

WHAT WE DO:

  • Interpolate contour lines at the interval your project requires
  • Plot spot elevations, drainage patterns, and existing utilities across the site
  • Map surface features including vegetation, structures, pavement, and grade breaks
  • Process data from total stations, drone LiDAR flights, and mixed field datasets
  • Organize deliverables into clean, engineering-ready CAD layers for direct hand-off to design teams
  • Coordinate with your firm's design standards so the topo integrates cleanly with downstream civil drawings

Deliverables & Formats

  • Civil 3D Surface Models: TIN surfaces, point groups, and contour mappings.
  • Layout PDFs: Set sheets at correct engineering scales.
