ascertain location of private on-site utilities.

3. Furnish title of survey, property location map, numerical and graphic scales, north arrow,

legend of symbols and abbreviations, bench mark datum, stamp or seal of registered

surveyor, and date.

4. Georeference survey to PA State Plane South NAD83 (feet) survey datum.

5. Provide Cadd electronic files at 1:1, in AutoCAD world coordinate system, with proper

north orientation. Survey base information shall be shown in this coordinate system with

bearings located in proper alignment.

permanent elements such as fire hydrant, manhole, inlet), indicating vertical elevation, and

northings and eastings.

7. Ensure that multiple layers (including spot elevations) do not read on top of each other

when viewed digitally or when printed. Survey will be used in 2-D as base mapping for

detailed design.

8. Separate, by layer, each component of survey, and label layers descriptively.

Boundary Survey Requirements

Provide boundary survey of Project Property, as follows:

1. Plot meets and bounds of overall property based on Deed Description. Label bearings and

distances of each property line segment.

• Top and bottom of walls, steps, landings, and curbs.

• Corners of building footprint, finished floor and door threshold elevations

and foundations, piers, bridges, culverts, wells, cisterns, towers.

• Base of individual trees over 2” caliper.

• Top and invert of drains, inlets, manholes, drainage swales.

• On grid approximately 20’-0 on center.

b. Plot contours at one foot interval, with tolerance of 0.25 feet, and at proper

elevation in Cadd file.

C. Locate Utilities:

a. Show location, size, material of pipe, direction of flow, gradient, surface and invert

elevation of sanitary and storm sewers; location, type and size of water and gas

lines, manholes, valve boxes, meter boxes, hydrants, fountains.; location of utility

poles, electric and telephone lines and fire alarm boxes; include all utilities above and
