Powell CWM provided land surveying and mapping services to the Missouri Department of Transportation for the outer road improvements in Grandview, Missouri. The services were completed under a Master Hourly Rate Fee Agreement and issued under Memorandum of Understanding (MOU) number KC-31.
The project was completed and delivered on January 15, 2016 and consisted of the following land surveying and mapping services:
Recovered and located the project control network established for MoDOT project #J4P3004 (MOU #KC-28) and extended control network throughout the project area.
Reestablished the existing horizontal alignment and right of way of Interstate 49 through the project area.
Reestablished the existing horizontal alignment and right of way of Outer Roads, Main Street, Truman Drive, 140th Street, 15th Street, High Grove Road, 129th Street, Booth Lane, and Route 150.
Provided mapping and tin file of the project area.
Mapped utilities per observed evidence together with evidence from plans and marking by Missouri One Call. Rim and inverted elevations were taken on all sanitary and storm sewer structures within the project area.
3D laser scanning was used to perform a majority of the project’s mapping. A Leica C10 laser scanner attached to our vehicle mounted terrestrial scanning platform (TopoLift) was utilized to map the project area. This method was chosen to avoid hindering traffic operations and for its speed in data collection.
Secondary control points were established throughout the project area for the scanning phase at approximately 500-foot intervals. These points were established using traditional surveying traverse methods and differential leveling.
The scan data consisted of 524 ScanWorlds and over 5.2 billion points that were analyzed, registered, and extracted using Leica Cyclone-Register software. The registered points were modeled and the roadway triangulated irregular network (tin) model was created in MicroStation utilizing TopoDOT point cloud processing software.
Powell CWM prepared and delivered a Pre-Design Survey, 3D point cloud, and a detailed survey report. The project was completed on time and within budget.
