Arden Hills, MN <br />Pavement Condition Assessment and Analysis <br />GIS Survey Mapping <br />Our data collection plan relies on a complete and up to date GIS street centerline. Shortly after the kick- <br />off, our Esri GIS experts will review and update the City's street centerline data to ensure there is an <br />accurate inventory of streets to be surveyed. City review of the centerline data is a critical path activity <br />to ensure timely and accurate data collection. Once the inventory is confirmed by the City, the IMS team <br />will prepare the GIS maps that guide field data collection. <br />IMS will produce survey maps to clearly indicate where our equipment will travel to collect data. While <br />we would expect the City's GIS environment to be highly accurate, we find it valuable to ensure that we <br />are aware of exactly which roads are included in the project and that we discuss how to proceed with <br />roads, such as private roads that should not be collected. Any questions regarding the roadway network <br />will be resolved prior to data collection. IMS will also confirm the linkage of the road segmentation to <br />the City database and GIS, using the customer defined existing road segments. <br />Pavement Condition Survey <br />Our two -person field crews will collect both outward facing and downward facing pavement imagery, <br />using one of our RSTs equipped with LCMS-2 3D pavement imaging technology. Pavement surface <br />distresses including linear cracking, fatigue cracking, block cracking, rutting, raveling, bleeding, edge <br />distress, and patched areas as well as right-of-way imagery will be collected on a segment -by -segment <br />basis, with each distress being captured by type, extent, and severity. The data and imagery that is <br />collected is then linked to the City's existing GIS data. <br />Safety Lilback <br />Front an <br />facing flashing <br />lights ensure high <br />visibility. <br />Samsara <br />Monitoring <br />Real time tracking <br />and reporting <br />Teledyne FUR <br />Ladybug 5+ <br />�M Captures 360' <br />Drive imagery at defined GPS Positioning <br />Manual entry intervals GPS with <br />of pavement integrated <br />distresses and field IMU, sub meter <br />observations positional <br />accuracy <br />- Pavemer <br />Ima[ <br />Profiler Linear Distance <br />Continuous right Positioning <br />and left wheel DMI for precise <br />path roughness linear distance <br />measurements measurements <br />Texture <br />Continuous <br />surface texture <br />measurements <br />IMS Road Surface Tester (RST) equipped with Laser Crack Measurement System (LCMS-2) <br />(Note: IMS has eight RST LCMS-2 equipped systems dedicated to municipal pavement management.) <br />IMS Infrastructure Management Services, LP 3 <br />
