The use of KMLs of 9 intersections on the Bruce Highway, with no requirement
for layout plans through preliminary stages (ordinarily requiring plans).
The main problem faced with this project was that no prior planning or options
were provided for detail design. Cost effective design alignment options were
required. The time taken to update and prepare layout plans with the level of
information required, would be extensive. The 12d model is not accessible to all
project stakeholders, compared to Google Earth (free).
The problem was solved by creating a process in 12d Model via a chain. The chain
manipulates the data for appearance purposes in Google Earth and the 12d design
was full computatored to allow for fast and efficient updates. Turnpaths, survey
data, edge treatments, and chainages were all converted. This allowed 2D
geometry to be optioneered numerous times within an extremely short period of
time (e.g. 12 design options in one day).
The use of KML/KMZ outputs from 12d Model to Google Earth allowed design options
to be expressed quickly and simply to the client and reviewers.
