Powell CWM provided land surveying and mapping services to the City of Lee’s Summit, Missouri for the roadway improvements of Ward Road from Route 150 to 163rd Street in both Jackson and Cass County. The services were completed under an On-Call Agreement for Land Surveying Services and issued under Memorandum of Authorization number 2013-300-2/R1. The project was completed and delivered on December 15, 2015 and consisted of the following land surveying and mapping services:
The establishment of a control network referenced to the Missouri State Plane Coordinate System of 1983.
The establishment of four control points in concrete and provided reference ties.
Reestablished the existing horizontal alignment and right of way lines of Ward Road from Route 150 to 163rd Street.
Reestablished the range line between Sections 36-T47N-R32W and 31-T47N-R31W, Sections 1-T46N-R32W and 6-T46N-R31W.
Provided mapping and tin file of Ward Road for Route150 to 163rd Street. Mapping corridor extended 100 feet on each side of the centerline of Ward Road.
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 for the scanning phase at approximately 500-foot intervals throughout the project area. These points were established using traditional surveying traverse methods and differential leveling.
The scan data consisted of 117 ScanWorlds and over 1.2 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 and then exported into AutoCAD for final project delivery.
The project was completed on time and within budget.
