Road & Villa Pad Layout Designer – Hilly Terrain
Budget: $500 – $800 USD
We have a 113-acre (45 ha) hilly property in a tropical region with heavy seasonal rainfall.
Terrain includes ridges, small peaks, ravines, and small rivers.
We will provide full topographic data from a professional RTK drone survey:
1 m DEM (bare earth, GeoTIFF)
Orthophoto (5–10 cm)
1 m & 2 m contours (DXF/SHP)
Slope map (GeoTIFF)
Property boundary & key features (SHP/DXF)
Scope of Work:
Design an all-weather road network connecting the property entrance to 4 villa pads (one per mini-peak).
Keep sustained grades ≤10%, short bursts ≤12%.
Add switchbacks where needed with minimum inner radius 12 m (SUVs).
Minimize cut/fill, avoid >20% slope areas.
Include basic drainage/culvert points (no structural engineering).
Design level villa pads tied smoothly into the terrain.
Deliverables:
Plan view (PDF) with road alignments, curve radii, key stations, and villa pads.
Profiles (PDF) for each road segment showing grades, elevations, and curve tables.
Centerlines & pads in DXF/SHP for CAD/GIS.
Google Earth KML/KMZ for 3D viewing.
Cut/fill volume estimates per road segment and pad.
Required Skills:
Demonstrated experience designing roads and pads on hilly terrain from DEM/contour data.
Proficiency in Civil 3D, Carlson Civil, or Softree RoadEng.
Ability to work with GeoTIFF DEMs, DXF/SHP contours, orthophotos.
Understanding of drainage design for high-rainfall environments.
