CSG Panaosnt co SANTAANA <br />WE ONE PaelECr <br />• Executed Cooperative Agreement (with utility companies), Caltrans, or other municipalities <br />Task C • Data Collection <br />Fletd Reconnalssence <br />C$G will conduct field reconnaissance to develop base mapping for the <br />project. Plaid reconnaissance efforts can be scaled up ordown, to <br />reflectwhather the aerial photogrommetry task Is authorized.. if <br />necessary, street and lane widths will he determined based an field <br />measurements taken at representative cross sections to supplement <br />available existing high-resolution orthorectifled Imagery. Existing utility <br />cover iocatlons and types will be field verified to assist In Utility <br />CoMfloation efforts. <br />Aerial phetegramovetry Survey (optional) <br />An eedal photogranimatry surrey, -which Involves the collection of <br />aerial photography and elevations, is a mere cost effective solutlomfdr <br />this projectiban a -traditional topographic ground -level survey, due to <br />the length of the segments to beimproved, and tlielr long distances <br />apart. Itis also h more accurate method of developing Wase trapping <br />then the use ofhigh-restitution orthorectifled aerial Imagery alone', <br />which may autof date -by several years and must be supplemented <br />with collected field data. <br />Aerial photngra.mmetfyservices will be provided by an serial <br />photogrammetry firm In conjunction with Wagner Engineering ,& <br />Survey. WE$ will set Vertical and horizontal controls for the project'in <br />accordance with City standards, prior to the aerial survey. Fallowing the <br />aerisl survey, supplemental ground shots can be cnilacted at <br />intersections for traffic signal modifications and ADA upgrades, as <br />needed. <br />Pavamant l/Isual .CondI*on Survey <br />As'a first order of work upon Notice to Proceed, CSG will conduct a <br />visual condition survoy to .evatuate the existing pavement condition for <br />the street segments identified as In need of pavement rehabilitation in <br />the RFP. The visual condition survey will consist of photographs of the <br />site to document the current condition of the site, and <br />fiecommendations based on the visual assessment. Some assumptions <br />would be made about the existing structural section thickness and R - <br />values to develop design recommendations. <br />F.xnntpleofpa &MIltrehawliatim <br />nnededduefFrrerantemnatracb®n <br />£xiunple of fselined paavernew rw1ure <br />Example of pitting <br />Pavement Desigri Report and Testing (Optional) <br />CSG has teamed with GooAdvantec Inc.

If authorized, coring will be performed to determine the <br />thickness and R•value of the existing structural section. <br />CSG will prepare a pavement design report Identifying the analysis procedures and tests used for the <br />Investigations, a description and limitations of any pavement rehabilitation materials listed in the <br />rehabilitation recommendations, two or more pavement rehabilitation design alternatives, the, raw test data, <br />exhibits identifying location of pavement cores taken,photos taken during the Investigations, and an <br />economic analysis of the rehabilitation alternativas based on CSG's previously designed and constructed <br />pavement project unit costs. <br />25E-345 <br />
