As-Built Survey – a survey performed after construction has been completed to locate the positions and/or determine the dimensions of structures and improvements.
Construction Staking – a survey performed before or during construction to set markers (lath, hubs, nails) to designate the design locations and/or elevations of proposed structures and improvements.
Elevation Certificate – a survey performed to determine the elevation(s) of pads, forms, and/or structures under construction, for the purpose of providing information relative to floodplain management practices.
Grading Plan – a map or drawing produced on which proposed grading (earthwork cuts & fills, retaining walls, drainage structures, etc.) is shown relative to the contours of existing ground surfaces. Existing ground information is typically provided by first conducting a topographic survey (see below).
Monitoring Survey – a survey performed on two or more occasions, in which structures or surfaces of concern are surveyed at designated locations, and the locations are then checked for horizontal and/or vertical movement over time.
Topographic Survey – a survey performed to determine the contours of the existing ground surface at the time of the survey, as well as the locations of existing natural and/or man-made features within the survey area.
Volumetric Survey – a survey performed to determine the current volume, or the change in volume, of earthwork areas, borrow pits, materials stockpiles, sumps, reservoirs, or other such areas.
