City of Everett | RFP No. 2023-057 November 2, 2023 IMS Infrastructure Management Services, LP 18 Image Sample Checking and Distance/Location Verification IMS will review a random sample of pavement images to confirm the accuracy of reported distress data using our Connect™ software. The detailed distress data for each image, including cracking and the classified and rated distresses, are superimposed over the image as well as displayed in a table. This allows QC reviewers to efficiently review and confirm that the condition of the road has been surveyed accurately. Connect™ also shows the vehicle GPS traces (collection polylines) overlaid on a street view map or an aerial image. They are shown together with the City-provided GIS shapefile polylines to provide quick and easy verification that the correct sections were driven, that section limits were correctly identified, and that the vehicle GPS is accurate. This all-in-one processing software makes location errors and misplaced sections things of the past, and the transparency improves client confidence in the delivered data. Quality Assurance/Quality Management Based on discussions with the City during the project initiation and kickoff meetings, we will develop a project-specific version of our standard quality management plan (QMP) for this project. The QMP will be formalized with the City’s approval prior to data collection. At a minimum, the plan will address the following: • How the data collection equipment will be calibrated and certified • What data quality control (QC) measures will be conducted before data collection begins and periodically during data collection • How data will be sampled, reviewed, and checked for quality Connect™ with distress data review Connect™ with shapefile and GPS trace
