NYCDDC Gravesend Bay Green Infrastructure Surveys

Brooklyn, New York

Project Overview

MFS Engineers & Surveyors was retained by Jacobs Civil Consultants Inc. to provide Land Survey services for the New York City Department of Design and Construction (NYCDDC) Gravesend Bay Green Infrastructure (GI) Surveys project. MFS conducted land survey of approximately 98,000 liner feet of roadway performed in accordance with NYCDDC Standards General Requirements GR 4.2.

Project Details

MFS performed, traditional, manned, topographic survey services to locate the physical features within the right-of-way lines such as, but not limited to; buildings, steps, stoops, curbs, edge of pavement, drives, striping, sidewalks, fences, walls, utility/light poles, street trees, tree lines, street furniture, and other features on the surface of the ground. MFS obtained spot elevations, top and bottom of curb elevations, back of walk and center line of roadway elevations at a 50’ stationing along the roadways and at spacing sufficient to develop contours at an interval of 1 foot. Elevations were taken at curb P.C., P.T.s and midpoints. First floor/garage floor elevations were determined at doors. Spot elevations along curbs, edge of pavement, sidewalks, wall, building corners and grade breaks were depicted.

MFS also located surface drainage structures such as manholes, catch basins, and headwalls. For storm drains and sanitary sewers, MFS obtained measurements to determine inverts, pipe sizes and material at accessible manholes and catch basins. Utility hardware such as valve covers, utility/light poles, hydrants were located. Subsurface utilities such as steam, water, gas, electric and communication was depicted based on surface features and existing mark out of subsurface utilities at the project site. The clearance (sag) of the lowest wire and the lowest point crossing the roadways (between the curb/edge of pavement lines) was located.

MFS’ photogrammetry survey team provided 1”=30’ topographic mapping for features 50’ beyond the right of way (ROW) lines along the project limits. To eliminate the need to trespass past the public right-of-way, as well as obtain as much detail as possible, two photo acquisitions fights were performed. All data was formatted in AutoCAD using NYCDDC’s standard layers, line types and blocks/cells.
