REFERENCE PLANES 002
...a practical example (part2) - the finishing steps...

We’ve got the planes positioned and the profiles extracted… all we have to now is
- create the design profile and
- build the finished corridor.
This is a follow on from previous posts:
“Widen at Grade.. the concept”
“ref planes 002 a practical example (part 1)”
ARD/EZY + Corridors - (how to create the corridor)

(a follow on from this post)
This has become topical recently as there have been questions on exporting ARD models to Trimble and Leica instruments for setout. (LandXML is an option but its cool to take the corridor)
Creating the corridor from ARD is a one click operation - there are 2 minor setups to do first.
We’re assuming the network is all modeled up in ARD so we’re just going to look at the steps to generate a full corridor object.
REFERENCE PLANES 002
...a practical example (part1)

One of the most common reconstruction jobs being done for Road Authorities these days is adding bus turning lanes to existing intersections.

The goal is to minimise the work on the existing roads by grading the new string to preserve and extend the existing road crossfall where possible. The challenge is to control the drainage around the new kerb - its a perfect example of reference planes in action.

REFERENCE PLANES 001
...widen a road at grade - the concept

-
At every training session we’ve done for local councils where road reconstruction is the brunt of the work being done, we get told that green field work is irrelevant and there is really only one question they want to know about:
“what is the easiest and most reliable way to widen a road at its existing grade?”

It starts our reasonably simple but can become complex when the road is suddenly part of an intersection which also has to be partially reconstructed while making sure the crossfalls stay within the max/min tolerances (roundabout reconstruction for eg).
The answer to all this (and a lot more) is REFERENCE PLANES
ARD/EZY + Corridors

(..part 1 of many..)
Question:
-Advanced Road Design(ARD)and Corridor Ezy(EZY)
Do they actually use Civil 3D objects?
short answer - yes
longer answer, follow link
(BTW, ARD and EZY are the same thing)
