MFS Consulting Engineers & Surveyor, DPC (MFS) provided professional land surveying services in support of the new loading dock and other improvements at Garfield High School in Garfield, NJ.
MFS performed a topographic field survey to the locate the accessible above ground physical features, such as, but not limited to; buildings, curbs, edge of pavement, drives, striping, sidewalks, fences, walls, utility/light poles, utility hardware, signs, street trees, tree lines. First floor/garage floor elevations were determined at doorways. Cross sections of paved surfaces were surveyed at a minimum of 50’ intervals and at low/high points. Spot elevations were obtained at a spacing sufficient to develop contours at an interval of one foot. Break line features such as top/bottom of curb, edge of pavement, top/bottom of slopes/swales/banks/walls, etc. were located.
MFS marked out subsurface utilities. SUE services included electromagnetic utility locating in compliance with Quality Level “B” of CI/ASCE 38-02, Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data, referred to as Standard 38-02. Any non-locatable utilities identified through records or other means were depicted on drawings at Quality Level “C” or “D”. SUE targeted the centerline of utilities for survey by MFS’ survey department. Tunnels, wide ducts, etc., if their configuration was known, were marked with paint to approximate each side of the system.
SUE technicians utilized a variety of utility locating instruments with different frequencies and power settings to detect and trace locatable utility systems within the project site. These instruments had a range of capabilities for both passive signal detection and active signal application through induction, direct connection, and inductive clamping. Utility designations were marked for survey by painting approximate centerlines on ground surfaces at reasonable distances, with flags installed as necessary. Paint and flags adhered to APWA uniform color code guidelines where applicable.
SUE technicians prepared field sketches depicting the location, trend, and configuration of detected utilities. These sketches also illustrated underground utility surface features, with color used to differentiate utility types. Annotations included size and material information where available, along with any project-specific field notes as deemed necessary. The field sketches were then provided to MFS to aid in identifying and field coding the utility mark-out, which MFS surveyed.
