Understanding of Need / Scope of Work = ;� <br />• Based on the City's request all segments within the three (3) networks will be <br />surveyed in 2024; <br />Distress types will be collected based upon actual surface conditions and physical characteristics <br />of the segment. Surveying methods will be conducted by remaining consistent with StreetSaver <br />& the Army Corp of Engineers/ASTM sampling guidelines. <br />We will use the City's GIS centerline live in the field to <br />reduce survey times and project schedules. If the City <br />has a recent high -resolution aerial (approx. 3") we will <br />use this file during our field survey efforts to verify <br />street measurements and other segment attributes. <br />For all surveys, the use of StreetSaver PMP-Tablet units <br />allows our staff to collect the necessary pavement data <br />live in the field. Due to StreetSaver being a cloud -based <br />PMP we will be assessing our field crew's work <br />daily/weekly at our office to ensure quality control and <br />management. <br />Our MobileRater Tablet methodology sets us apart <br />from the competition since we are using a paper -less <br />C <br />Saver' <br />ram.

Bucknam will obtain <br />measurements of each streets width, length and surface classification and compare it to existing <br />StreetSaver data. <br />1. Field Attribute Data (updated and/or verified) <br />• Street name, from/to, indicating the assigned limits of the section, a Segment ID <br />(arranged west to east and south to north) <br />• Street ranking indicating local, alley, arterial, collector, # of lanes, surface type <br />• Historical PCI tracking from previous inspections and 2024 PCI inspections <br />• Segment quantities, indicating the length, width, and total true area of the section <br />• Pavement distresses compliant with StreetSaver — OCTA guidelines (i.e. alligator <br />cracking, block cracking, rutting, long/trans cracking, weathering, etc. <br />• Provide City with "discrepancy report" indicating variances between field data <br />collection and previous PMP database <br />2. Conditional data will be evaluated for all street segments and will include: <br />• StreetSaver 20 AC & 19 PCC distresses by type, severity and sample area <br />• PCI ratings (0-100); per segment, per grid zone, per maintenance zone and citywide <br />We welcome staff members from the City of Santa Ana to join our surveys. All pavement data <br />will be entered into the City's current StreetSaver licensed software. <br />3-4 <br />
