FIELD REVIEW Once the pavement network to be surveyed has been verified, the inspection of approximately 300 miles of local streets will be made where all 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 Army Corps of Engineers sampling guidelines and MicroPAVER field manuals while being flexible to current City practices. The survey will be performed by a team of experienced and trained Berryman & Henigar personnel using an automated system to collect field data (collection of data is recorded into our field Compaq iPAQ units, then downloaded into the matching MicroPAVER database files). This data is collected in -hand (see image below) then transferred at the end of the day to our in -house workstations for quality control and data population. The first key step in surveying a specific pavement section is to record /verify its length and width while assessing for ride and drainage ratings. From there, the surveyor will perform the necessary condition - distress survey and it is important to note that pavement segment dimensions /surface areas, along with the distress quantities are accurate within tolerable limits. This is noteworthy due to the "implied" accuracy of reporting (length and width to the nearest foot, surface area, and distress to the nearest square foot). Based on street conditions and /or traffic, our staff will measure specific or distinct distress types by hand. An example of the information that is collected /verified during the survey for the pavement management database is listed below: A. ATTRIBUTE DATA • Designation of ownership or jurisdiction such as City, County, state or federal agencies, and privately owned property • From /to, indicating the assigned limits of the section • Name of street • Segment codification, which will allow for assignment of special designations (i.e., truck routes and school zones) as well as maintenance districts • Street classification indicating function, such as local, arterial, or collector, etc. • Number of travel lanes San • Presence of curb and gutter and sidewalk in each section (Critical for GASB 34) • Segment quantities, indicating the length, width, and total area of the section (Critical for GASB 34) • Surface type: AC, PCC, gravel, dirt We welcome staff members from the City to join any portion of our survey efforts. Condition data will be evaluated for all street segments and shall include the following condition characteristics: B. CONDITION CHARACTERISTICS 11
