SECTION 13 – AS-BUILTS
13.1
GENERAL
This Section specifies requirements for providing the Owner with a post-construction
As-Built drawing and electronic file.
13.2
SUBMITTALS
After the completion of the project, the contractor shall supply the Owner with one
(1) hard copy of the As-Built plan and one (1) copy of the As-Built file electronically.
Electronic submittals shall include a PDF version of the As-Built construction plans
and a georeferenced AutoCAD (.dwg) file of the overall As-Built site and utility
plans.
The contractor shall obtain a set of plans for the As-Built from the design engineer.
The submitted plans shall be black and white with all As-Built data in red. The plans
shall have the following information located via GPS according to NAD83 Virginia
State Plane South (horizontal) and NGVD 29 (vertical) and called out in a legible
format:
A.
For gravity pipes: size, type (material), length, alignment, and slope.
B.
For pressure pipes: size, material, alignment, valves, and tie-in locations (if
needed).
C.
For manholes (existing and proposed): northing and easting, rim elevations,
verification that the frame and cover are standard or bolted or gasketed,
diameter, and inverts in and out of all pipes.
D.
For cleanouts (existing and proposed): northing and easting, top elevations,
and inverts.
E.
For bends and tie-in points: size, angle (22.5, 45, etc.), direction (vertical,
horizontal), material, northing and easting, and inverts.
F.
For oil/water separators and grease traps: rim(s) elevations, top of slab
elevations, northing and easting of the rims and corners of the structure,
internal piping elevations, callouts on the plan detail where the installed
structure differs from the plan detail, manufacturer, model number, length,
width, total volume of unit, baffle wall location, and location of the orifice in
the baffle wall.

G.
For pump stations: top/rim elevation, distance above ground for the top of the
station, total depth from top of slab to base section inside of wet well, float
elevations, invert in elevations, and wet well inside diameter. This shall also
include a statement that all other pieces of equipment (i.e. guide rails) as
shown on the plan and specifications are present and installed correctly.
H.
Water Lines: size, type material, length, depth to top of pipe, and alignment.
This shall also include northing and easting locations of all valves, bends, and
other appurtenances.
I.
Fire Hydrants and Blow-offs: northing, easting, elevation of the base of the
hydrant, make, model, and year.
J.
For As-Built notes: All sheets shall have a minimum of 3 northing/easting
cross points and provide the coordinate system used. Typically, the datum
used is Virginia State Plane South, NAD 83 (horizontal) and NGVD 29
(vertical). The accuracy of the data shall be to the nearest 0.01 feet.
K.
All plan sheets shall have the appropriate UTL, POD, or LDP number on
them.
To supplement the labeling mentioned above, the As-Built shall also label all pipe,
fittings, structures and other appurtenances not mentioned above on the plan sheet.
The As-Built cover sheet shall provide separate Pipe Schedule and Structure Schedule
charts showing a comprehensive materials list.
