Consulting Services Agreement between City of San Leandro and CSG Consultants, Inc. for Washington Avenue Reconstruction, Project No. 2018.4020 Exhibit A – Page 2 of 4 transition from the reduced roadway crown within the project limits to the existing pavement on side streets. Consultant will collect detailed topographic survey data for the intersection corners where curb ramps were found or measured to be non-ADA compliant during preliminary field walk and require replacement. The survey may be performed using a combination of Terrestrial LiDAR and supplemented by field surveys with Robotic Total Station. AutoCAD Base Map will be prepared based on City of San Leandro CAD Standards. All planimetric features, visible surface utilities, will be mapped including inverts of sanitary sewer and storm drain structures. Street cross-sections every 50/100 feet will be provided. Horizontal and vertical control will be based on California State Plane Coordinates (NAD83, NAVD88). Alternatively, the consultant can use local City benchmark data and a local basis of bearings if preferred. City will provide the type and location of survey monuments and the elevation of benchmarks. Best fit right of way limits from available records will be shown on the construction drawings. No right of way acquisition will be necessary for the project; however, should the consultant encounter areas where the proposed improvements will encroach upon private property, consultant will review those areas with the City, and make adjustments to the proposed improvements if necessary. If any improvements, e.g., driveway conforms are required to be constructed on private properties, consultant can assist the City as additional services to prepare plat and legal descriptions to obtain temporary construction easements. Filing corner records prior to and after construction is not part of the project scope. The following services are excluded, but can be provided as additional services: • Preparation of a traffic safety plan or lane closures to complete the topographic survey • Preparation of right of way maps by retracing, locating and tying to survey monuments • Preparation of corner records and coordination necessary to relocate destroyed monuments • Performing and preparing a Record of Survey or Corner Record(s) • Preparation of plat and/or legal descriptions for right of way or construction easements • Obtaining or purchasing Title Reports for adjacent properties Deliverables Topographic survey in both electronic version and hardcopies. Task C – Geotechnical Investigation Consultant will apply for a no fee City of San Leandro encroachment permit to collect pavement cores and subgrade samples. These locations will be marked in the field for USA clearance. Field work will consist of coring along Washington Avenue on either side of the street. Four (4) cores are proposed along the corridor within the parking lanes. Subgrade samples will be collected from a depth of 0-3 feet (measured from lip of gutter) for R value tests. Because there is a high probability that soil cement treatment of the road base will be evaluated during design, the consultant shall collect samples at this time to make this determination. All work will be performed within parking lanes, except that at least one of the cores will be in the street to include identifying existing roadway structural section. No traffic control will be provided. Additional sampling for Cement Treated Base (CTB) treatment is not included in this scope but can be performed as an additional service. All field work is planned to be completed within one working shift that includes, pavement coring, and pavement subgrade sampling. Laboratory testing for R-value will be conducted on collected two (2) samples. Core samples will be measured for asphalt thickness and photographed for documentation. A summary of the field work will be provided in a table.
