Project Summary

The use of KMLs of 9 intersections on the Bruce Highway, with no requirement for layout plans through preliminary stages (ordinarily requiring plans).

The Challenge

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 Solution

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 Result

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.
