City of Santa Ana <br />Pavement Management Program Update RFP No. 19-070 <br />August 6, 2019 <br />databases developed by NCE. These are then analyzed to develop funding estimates for the future and <br />work plans. The results are typically presented in reports, AutoCAD maps, or GIS shape files. <br />Specialty Pavement Testing and Pavement Design Options <br />As an optional, added -value service (costs can be provided <br />upon request), NICE can perform non-destructive pavement <br />deflection testing to evaluate the subsurface or structural <br />capacity of the existing pavement on rehabilitation slated <br />streets. NCE owns and operates a Falling Weight <br />Deflectometer (FWD), which is a powerful device for <br />measuring the response of pavements under simulated <br />wheel loads and estimating their subsurface and structural <br />capacities. The test procedures are performed in accordance <br />with California Test Method (CTM) 356. <br />Deflection testing can quickly and cost-effectively measure <br />in -situ pavement section strength and can identify structural <br />deficiencies for a given traffic loading and future expected <br />traffic growth, which can help reduce the chance of under <br />designing or over designing pavement rehabilitation. Streets <br />identified for reconstruction can sometimes indicate that <br />reconstruction is not necessary and more cost-effective <br />rehabilitation alternatives are feasible. It should be noted that <br />FWD testing is time -sensitive and the data is only valid for <br />pavement design within two years of the testing. <br />Deflection testing must be correlated with knowledge of the pavement structural section (i.e., thickness of <br />AC and base) before meaningful analysis can be performed. Representative coring is budgeted on arterials <br />and collectors to provide this information following the clearing of utilities. The core holes are filled with <br />cold patch for AC roads and with rapid set grout for portland cement concrete roads. <br />NICE recently performed FWD testing, coring, analysis, and pavement design for the City of Lemon Grove, <br />and is currently providing similar services for the Montebello Grade Separation project's Haul Route in <br />Montebello. <br />Pavement and Civil Engineering <br />Street rehabilitation extends well beyond the pavement and often requires important considerations, such <br />as striping, curb and gutter repairs, pedestrian and bicycle improvements, signage, utility relocation, <br />drainage improvements, and ADA compliant curb ramps and sidewalks. NCE has developed outstanding <br />working relationships with our clients, implementing projects similar to the City's. NCE provides civil <br />engineering services on -time and designs that are technically innovative and highly cost-effective. NICE <br />has experience designing thousands of roads throughout California, including developing PS&E. We <br />thoroughly understand the impact recommended pavement designs can have on the roadway system. <br />Geotechnical Engineering <br />NCE's geotechnicai engineers understand the significance of proper support on competent subgrade soils <br />to limit damaging settlement and future cracking. For example, based on field exploration and soil/rock <br />laboratory testing, we are able to accurately assess the engineering properties and the presence of <br />4 °ONCE <br />Page 17 <br />25D-20 <br />
