URBAN ROADS DESIGN (4 roads, 4 T-intersections and 1 crossing intersection)

The times for Task 1 have been excluded from the accumulated times to provide more realistic productivity calculations for international projects, since the surface creation was based on South African survey data formats.

Model Maker is extensively used in South Africa by surveyors to deliver survey information to engineers. The TOT file format contains all surveyed points as well as the triangulation done by the surveyor. The same process is available for a survey that was done in Civil Designer.

Process:

Autodesk® Civil 3D® & iDAS

Select the function "Create surface from TOT file"

Autodesk Civil 3D only

Extract points data from TOT file manually
Import points
Draw triangulation manually between points
Create surface from CAD objects

Process step 1:

Autodesk Civil 3D & iDAS (2 minutes)

Select the function "Create corridors from polylines"

Autodesk Civil 3D only (28 minutes)

Create alignments
Calculate super elevation for each alignment (for drainage purposes)
Create profiles from surface
Create profile views
Create vertical alignments (profiles)
Create corridors
Create corridor road edge profiles (static profiles are created that must be redone with every change)
Set profile view band sets
Create corridor(s) top surface
Create corridor(s) datum surface
Create sample lines

Process step 2:

Autodesk Civil 3D & iDAS (15 minutes)

Adjust vertical alignments

Autodesk Civil 3D only (15 minutes)

Adjust vertical alignments

Process step 3:

Autodesk Civil 3D & iDAS (5 minutes)

Create all intersections

Autodesk Civil 3D only (60 minutes)

Create all intersections

Process :

Autodesk Civil 3D & iDAS (5 minutes)

Create combined surfaces
Add surface labels*
Add chainage labels*
Add alignment name labels*

Create survey grid

* iDAS can create and edit all selected globally

Autodesk Civil 3D only (12 minutes)

Create combined surfaces
Add surface labels
Add chainage labels

Create setting out data tables
Create survey COGO points
Create COGO point array

Process :

Autodesk Civil 3D & iDAS (4 minutes)

Create plan and profile sheets for all alignments automatically
Create plan production for cross-sections
Adjust cross-section datum and section view height for all cross-sections
Create cross-section sheets
Calculate quantities
Export quantities in columnated format

Autodesk Civil 3D only (16 minutes)

Create plan and profile sheets manually for each alignment, and edit to fit in the viewport on each sheet
- Create view frames
- Create sheets
- Adjust profile view viewports
Create plan production for cross-sections
Adjust cross-section datum and section view height individually
Create cross-section sheets
Calculate quantities
Export quantities in Autodesk Civil 3D format
Manipulate data in the spreadsheet editor

Notes:

The timing above excludes:
- horizontal alignment adjustments
- plan production templates creation
- assembly development
- cadastral data cleanup
- title block details
- label adjustments
- alignment and intersection setting out table sheets
- benchmarks
- services
- sheet set creation
- acquiring data from the surveyor
All tests were done by an experienced Autodesk Civil 3D and iDAS engineer.
