 Sufficient topographic information will be provided for the design of proposed curb ramps and ADA accessible areas;  Matrix will establish horizontal control based on North American Datum 1983 (New Jersey State Plane Coordinate System-NAD 83) and North American Vertical Datum 1988 (NAVD 88), utilizing GNSS static methods and closed loop traverses;  Benchmark(s) to be set on site for future use;  Matrix will establish the water surface elevation of Crystal Lake.  Matrix will provide an Existing Conditions/Survey Control plan;  As determined in consultation with the Project Engineer and the Township of West Orange as needed, Matrix will coordinate utility mark-outs Matrix will map all surface features including all existing elevations, high and low points, contour lines at 1-ft-intervals, elevations and street grades, utility casting, manholes, fire hydrants, catch basins and invert elevations of catch basins, pipes and drainage structures (e.g., size, material, type, rim/grate elevation, and invert elevations at the inlet and outlet), existing site furniture (including but not limited to fences, sign poles, benches, tables, light and utility poles, etc.), tree centerline, diameter and breast height (DBH) and drip line locations of trees 6” DBH and above, tree stump centerlines and diameters, tree pit extents, driveways, curb cuts, crosswalks, ramps, stairwells, existing buildings and structures. Matrix will utilize conventional land survey, plus possible combinations of 3D laser scanning and SLAM LiDAR technologies to perform this survey. Conventional survey equipment will also be used for establishing survey control and collecting topography in shadow areas not included in the 3D laser scan. Matrix will use Leica GNSS equipment to establish benchmarks and horizontal survey control on site. Matrix will map underground utilities, engaging the services of a subsurface utility provider (GPR) is excluded, to obtain Level B SUE survey per ASCE Standard Guideline for the Collection and Depiction of Existing Subsurface Utility data in areas designated by the Project Engineer. Matrix will also depict Water and Sewer mapping on the survey. Exclusions and assumptions made for this proposal:  The Client will provide Matrix with the existing topographic, property boundary, and utility mapping or information if pertinent to the project.  It will be

d assumptions made for this proposal:  The Client will provide Matrix with the existing topographic, property boundary, and utility mapping or information if pertinent to the project.  It will be the responsibility of the Client to provide and coordinate the scheduled access to the site for Matrix staff as needed.  Matrix will provide deliverables as specified in the RFP. Matrix will provide all electronic copies in Civil3D AutoCAD 2024 format (or other AutoCAD version if required).  Soft-Dig is not included in this proposal.  Construction stakeout/layout is not included in this proposal.  The proposal does not include TV scanning of the storm and sanitary lines.  The proposal does not include cleaning of the storm/sanitary lines.  The proposal does not include a designated tree survey.  The proposal does not include wetland delineation services under the survey task.  Matrix will locate wetland delineation markers set by others. 4
