SANTA ANA. <br />City of Santa Ano <br />Pavement Management Program 2018 <br />Quality Control Plan <br />Therefore, an up-to-date maintenance and rehabilitation history file in the PAVER database <br />is desirable, both for historical accuracy as well as to provide additional quality control. <br />If PCI Decreases 10 points: <br />The section is checked to see if the average deterioration rate (usually 3 to 4 points per <br />year) is exceeded. If the drop in PCI is within the range of what is acceptable, no further <br />action is required. If the drop is more than the acceptable range, a re -inspection will be <br />performed. The default performance curves in the pavement management software form <br />the basis for what is acceptable. <br />2.3. Inspectors' Qualifications and Experience <br />All NCE's inspectors are required to attend formal training on condition distress inspections. <br />For example, any of NCE's inspectors working on the LTPP project are required to attend a <br />week-long training workshop every year to maintain their certifications. The Regional <br />Transportation Commission (RTC) of Washoe County requires inspectors to be calibrated <br />prior to performing any work using the ASTM D6433 protocols (also known as the pavement <br />management inspections). <br />For pavement management (or ASTM D6433) inspections, NCE's technicians underwent the <br />OCTA technician certification exercise held in May 2017. <br />Similarly, in agencies that use the Paver system, NCE's inspectors attend the distress <br />training conducted by the Metropolitan Transportation Commission (MTC). After the formal <br />training, they work with an experienced inspector before they are allowed to work on their <br />own. Within the first month of working on their own, up to 20% of their work is checked <br />weekly. Any necessary corrections are made immediately. <br />Finally, NCE conducts a one -day training and calibration workshop for all NCE staff involved <br />with data collection. This is conducted once a year. <br />Resumes of technicians utilized on this project are included. <br />4 <br />Engineering & Environmental Services <br />55B-133 <br />
