SCOPE

A local council received funding from Transport for NSW’s Safer Roads program for the design and implementation of 4 road safety projects. 20km of the road was required to be surveyed; the following information is to be contained in the survey:

• Investigation and location of existing traffic facilities i.e. line marking, signage, guideposts etc.
• Items likely to affect installation of any proposed measures i.e. driveways, culverts, power poles etc.
• The survey is to be undertaken with appropriate traffic control if required and if required is to be in accordance with RMS “Traffic Control at Work Sites Manual”
• 100mm Accuracy

SOLUTION

• Use Nextcore UAV LiDAR as survey capture
• Fly from 10 safe locations across the length of the site
• Reduce static observations from survey grade base & LiDAR base against CORS
• Survey connection to state survey marks & RTK GPS survey QC points across entire job length
• Feature extraction from LiDAR point cloud
• Survey features extracted in accurate 3D space

RESULT

• 20km of Survey Accurate data captured in 2 days
• Feature extracted & drafted in 4 days (compiled hours)
• Delivered in 3 days from capture
• Project delivery in 3D platforms as well as AUTOCAD in survey layers
