344-24 Exhibit A-West Orange 2022 SRTS PE Proposal Rev 07-16-2024.pdf

SRTS-2022 Design Assistance Program Township of West Orange November 13, 2023 Revised July 16, 2024 Page 4 of 8 Primary Tasks: 1. Establish existing ROW and no-access lines using existing plan and deed information. 2. Perform bench run, based on recovered survey control. 3. Conduct topographic survey, utility location survey and ROW location survey. 4. Provide a “traverse.dgn” file containing the survey and supplemental control points along with any traverse created for the project. 5. Develop a table summarizing points, coordinates, elevations and descriptions to be inserted into the traverse file. a. The points to be used as benchmarks for construction will be identified in the table. b. A separate file containing swing tie data will be provided as a supplement to the data provided in the Field Notes. Technical Assumptions: 1. GPI will utilize a combination of conventional survey methods, GNSS survey methods, and 3D laser scanning (LiDAR) methods to collect the survey data. It is estimated that features extracted from the LiDAR point cloud will have a tolerance of less than one-quarter inch (¼”). 2. A highway occupancy permit will not be required. 3. Lane closures will not be required. Prepare Base Maps (3025): GPI will perform a field edit of the base mapping to verify its accuracy based upon the survey data collected in Activity 3020. The mapping efforts will adhere to the NJDOT Survey Manual, BDC13T-04. The ROW and no-access lines for all adjacent parcels will be established from deeds and plotted on the base maps in accordance with NJDOT ROW procedures and guidelines. CADD processing and editing – All files will be developed using NJDOT standards with regards to level, color and symbology. These files will be used during compilation of the planimetric features to ensure consistency across the entire project. Editing of the digital files collected during compilation is performed on individual workstations. At this stage individual models are combined and edited to produce the final map. All the scanned data is run through a final CADD edit. This is done to ensure that proper line styles, line weights, levels and symbology conform to NJDOT Survey Manual and CADD Standards Manual. Digital Terrain Models (DTM) – A DTM will be created from the survey work. The DTM will be of sufficient accuracy to evaluate existing pavement grades and establish new pavement

CADD Standards Manual. Digital Terrain Models (DTM) – A DTM will be created from the survey work. The DTM will be of sufficient accuracy to evaluate existing pavement grades and establish new pavement grading. The surface DTM will be established to the extent of the project limits, including roadside surfaces, at a minimum to the ROW line. ROW will be developed and plotted from deeds for the parcels within the project limits. We will generate final contours. The quality control process will include a field check. The base map data will be reviewed for features missed during data capture and to review the final CADD files for consistency and accuracy. Potential DTM errors, such as spikes or anomalies, such as significant erosion near a parapet wall, may be resurveyed for verification before the final files are created. A quality assurance review will be performed on the final CADD files. Primary Tasks: 1. Field edit base mapping to verify field data. 2. Update base mapping on an as required basis to include utility underground information as received from the Utility Owners on the project site. 3. Plot the ROW and no-access lines from deeds, maps, and/or plans. 4. Prepare final mapping of existing topography information. 5. Perform QA review on the final base mapping. Prepare Horizontal and Vertical Geometry (3030): GPI will layout the proposed curb ramps and calculate the proposed horizontal and vertical geometry where curb ramps are deemed to be non-compliant with ADA requirements. The proposed geometry will be tied into the project baseline as developed by GPI, with proposed work and project footprint defined over the base mapping to produce an accurate depiction of the proposed impacts.
