Understanding of Need / Scope of Work (a 2. Automated Digital Roadway Imaging (Optional Task 4.1) survey; Bucknam has recently performed this service for the cities of Fountain Valley, Cypress, RSM, Santa Ana, La Habra Heights, Tustin, National City and Palm Desert for PIMP and ROW inspections. MicroPAVER sampling method used. Distress types will be collected based upon actual surface conditions and physical characteristics of the segment. Surveying methods will be conducted by remaining consistent with MicroPAVER & the Army Corp of Engineers sampling guidelines while being flexible to current City practices. We will use the City's GIS centerline live in the field to reduce survey times and project schedules. If the City has a recent high- resolution aerial (approx. 3 ") we will use this file during our field survey efforts to verify street measurements and other segment attributes. Our use of MicroPAVER- Tablet units allows our staff to collect pavement data with the City of Santa Ana's MicroPAVER database live in the field. At the end of the day all electronic data is transferred to our office for quality control and management. Our Tablet methodology sets us apart from the competition since we are using a paper -less inventory process to enter data; this in turn generates cost savings to enhance other portions of the project such as CIP reporting, MicroPAVER training, and on -call services. Roadway Verification Survey -A listing of the field attribute data that is updated /verified during the survey for the pavement management database is listed below. Bucknam will obtain measurements of each streets width, length and surface classification and compare it to existing PAVER data. Discrepancies in the data will be tabulated and reviewed by Bucknam and the City prior to any update within PAVER. 1. Field Attribute Data (updated and /or verified) • From /to, indicating the assigned limits of the section, sample test areas, street name, a street codification (arranged west to east and south to north) • Street ranking indicating local, alley, arterial, collector, # of lanes, surface type • Historical PCI tracking from previous inspections and 2016 PCI inspections • Segment quantities, indicating the length, width, and total true area of the section • Pavement distresses compliant with MicroPAVER — OCTA guidelines (i.e. alligator cracking, block cracking, rutting, long /trans cracking, weathering, etc. • Provide City with "discrepancy report" indicating variances between field data collection and previous PIMP database 2. Conditional data will be evaluated for all street segments and will include: • MicroPAVER 20 AC & 19 PCC distresses by type, severity and sample area • PCI ratings (0 -100); per segment, per grid zone, per maintenance zone and citywide i Other known or found environmental issues (standing water, site condition, etc.) • Corrections / changes to the database shall not be made w/o prior City approval We welcome staff members from the City of Santa Ana to join our surveys. All pavement data will be entered into the City's most current licensed software (version 7.0.3). All items listed above will be maintained by our staff for the duration of this project. 3 -4 25D -15
