Project: Design a local road

Project brief

The brief

Step 1 — Survey and surface

1. 1Import points with description keys; group ground shots.
2. 2Build EG with breaklines and a boundary; check it.
3. 3Produce an existing site plan with contours.

Step 2 — Geometry

1. 1Lay out the alignment with criteria-based design.
2. 2Create the EG profile and design a grade with PVIs and vertical curves within your standard's limits.
3. 3Keep minimum grades for drainage along kerbs.

Step 3 — Corridor and drainage

1. 1Build the assembly and corridor with daylight targeting EG.
2. 2Create the corridor top and datum surfaces.
3. 3Lay out a stormwater line with pits at low points and at intervals; draw it in profile; check cover.

Step 4 — Outputs

1. 1Create sample lines and cross-section sheets.
2. 2Calculate cut and fill with the Volumes Dashboard; state factors used.
3. 3Produce a plan/profile sheet (Plan Production tools or layouts) and a one-page design summary.

Deliverables

Common mistakes

• Designing geometry before checking the surface.

  Bad survey points and missing breaklines give a wrong existing ground; every later step inherits the error.

• Ignoring the chosen standard's limits.

  Keep criteria-based design on and record any departure with a reason.

• Reporting volumes without stating factors.

  Always state bulking/compaction factors and which surfaces were compared.
