- Project Understanding / Scope of Work pavement inspections. Our services are a proactive and cost efficient GPS survey methodology that will allow for the collection of numerous GPS locations using "one" set of digital imagery (e.g. five citywide infrastructure surveys for the cost of one). We always tell our clients, regarding this task service, "It has to be the right fit at the right time ". If the City is looking to proactively collect numerous assets under one survey effort within the next 12 to 18 months, this is the solution. Beyond the pavement survey capabilities, the City will be able to collect other infrastructure assets in the future such signs, driveways, catch basins and other ROW features; a tremendous costs savings that could reach $400,000 over the next 3 years. With verification of street segmentation, the inspection of approximately 105 centerline miles will be surveyed (or citywide). MicroPAVER - Army Corp of Engineers AC and PCC distress types will be collected based upon actual surface conditions and physical characteristics of the segment while being flexible to current City practices. Our automated digital imaging allows technician to collect the following: • Continuous pavement imaging (images taken every 5 meters, competition typically surveys at every 8 meters /25 feet intervals) • Surface roughness ratings (IRI); Rutting depth (full width of lane or street) • Imaging captures 100% of each pavement segment (notjust one lane) • Data transfers seamlessly to MicroPAVER • 2mm pixel images allows for centimeter horizontal and vertical accuracy The first survey process will involve the mobile GPS vehicle taking approximately two- week's time to survey the Santa Ana's street network; additionally, the vehicles drive the posted speed limits. The images that are collected are taken by using Sony digital stereographic cameras (6 cameras) positioned on the vehicle. The images have a resolution of 1600x1200 and are geo- referenced by means of inertial GPS equipment contained within the van; images are taken every 4 to 6 meters, 15 ft. intervals. The quality of the imagery and its GIS / record collecting capabilities within the software provided allows the technician to accurately identify the required pavement distresses defined by the pavement software and the project (distresses are collected in- house). Survey vehicles are equipped with digital measuring instrumentation (DMI) that will be used to verify all pavement section lengths and widths. Our vehicles can be equipped with road roughness rating equipment, strip mapping cameras and are set to record 360 degree street imaging. The survey will be performed by the Bucknom team that is experienced and trained in infrastructure condition assessment using LambdaTech's "Feature Extraction" software. IM]
