Arden Hills, MN <br />Pavement Condition Assessment and Analysis <br />Comprehensive Bike Path Survey <br />The trail based survey is performed by driving each <br />linear mile of the approximate 16.5 miles of paved <br />trails maintained by the City which provides detailed <br />data to determine the condition of each trail segment. <br />Our new generation of sidewalk and trail testing <br />vehicle (SST) is equipped with three point lasers that <br />will continuously measure cross -slope, as well as <br />transverse cracking and vertical slab displacement. The <br />field operator will supplement this with entry of major <br />events and distresses such as obstruction and tree <br />intrusions. IMS will provide a Sidewalk Condition Index <br />(SWCI) which is a 0-100 score that is similar to a PCI or <br />OCI. The SWCI is a repeatable and representative <br />rating for each sidewalk/trail segment that is utilized <br />by IMS client's for prioritizing remediation and <br />reconstruciton. <br />The SWCI was developed by IMS in 2014 when we IMS Laser -equipped Sidewalk <br />launched our SST platform. We have been able to provide our Surface Tester <br />clients with an approach to sidewalk management that is like <br />what is used for pavement management. Over the past 5 years, as a function of larger ADA Transition <br />plans, IMS has worked with delivering this data for developing M&R and ADA Transition plans. <br />Digital Imagery Collection <br />IMS will collect imagery from the field surveys <br />via the field collection vehicle at defined <br />intervals. The imagery collected in the field is <br />utilized during the QC/QA process to verify <br />field operator input and identify additional <br />obstruction details. The City will receive the <br />imagery. This imagery can be delivered via a <br />GIS-hyperlink and hard drive for the City to <br />maintain. <br />Deliverables <br />The following products can be delivered to the City: <br />• Report summarizing the findings of the pavement condition survey <br />• Client Review Spreadsheet (CRS) with inventory, charts, and graphs <br />• Esri geodatabase containing updated pavement information including distress information <br />IMS Infrastructure Management Services, LP 7 <br />
