Progress Monitoring and As-Built of Heritage Drive Rebuild

Owner: The City of Calgary

Data collection with terrestrial mobile mapper.  LiDAR survey and panoramic photos of entire road right-of-way at all phases of road construction:

  • ¤excavation
  • ¤subgrade
  • ¤base gravel
  • ¤fine gravel
  • ¤base asphalt
  • ¤second lift asphalt
  • All road elements on GIS layers, such as:

  • ¤streetlights
  • ¤pavement markings
  • ¤concrete curbs / barriers
  • ¤fencing
¤Post-construction surface shows the extent of changes to the right-of-way since flood damage.
¤Combined with inspection reports, City has a detailed record of the project from start to finish.

Deliverables

¤ArcGIS shapefiles for roadside assets
¤AutoCAD drawings - contour plans, roadway plans and profiles, roadway cross-sections, cut / fill volumes.
¤Report summarizing methodology, results and recommendations for further use.

Value-Add

¤Employing mobile mapping during the project ensured data was obtained without interruption / delay to the contractor.
¤Corrections to ‘legacy’ data in existing database:
¤Two streetlights did not exist
¤Two streetlights out of position by approximately 15m and 30m
¤Significant corrections to the streetlight record representing approximately 20% of the asset class in the project limit.
