All plans approved for construction which include elevations,
distances, material lengths, thicknesses or depths shall be affirmed
through submission of an as-built (or as-constructed) plan as part
of the final plan approval process. The as-built plan shall accurately
depict the final constructed development indicating which improvements
have been installed in accord with the approved plans and detailing
any changes as approved by the Township.
A. Submission. One legible paper print of the as-built plans and one
compact disc with the plans in PDF format shall simultaneously be
submitted to the Township and one of each to the Township Engineer.
B. Format.
(1) The as-built plans shall be generated using the approved plans (as
revised through construction) with the plan/design figures struck
through with a single line and the as-constructed measurement annotated
immediately adjacent.
(2) All deviations from approved plan data shall be documented by field
measurement by a registered land surveyor, licensed in good standing
to practice surveying in the Commonwealth of Pennsylvania.
C. Water and sewer. Water and sewer as-built plans shall be coordinated
with the respective authorities.
D. Plan information. The following information shall be shown on the
as-built plans. Deviations from the approved plans shall be subject
to a request from the Township Engineer for calculations sealed by
the applicable qualified professional which document that the as-constructed
condition does not violate the original intent by decreasing flow
capacity or a safety standard below the criteria set by this chapter.
(1) Storm sewer, including revised topography for basin/BMPs (if needed),
basin/BMP berm height and width, outlet structure elevations, emergency
spillway elevation and length, basin/BMP volume calculations, storm
pipes and inlets (including pipe size, slope, inverts, grate elevations),
and location of all BMPs, including snouts, bottomless inlets, depressed
landscape islands, infiltration trenches, porous pavement, etc.
(2) Deviations in grade on gravity-dependent improvements (e.g., ditches
and pipes) to verify that the installed flow capacity meets or exceeds
the design capacity.
(6) Road elevations, layout, and striping; and if intersections have
been revised significantly, sight distance. Finished roadway improvements
shall be measured at cross-section intervals matching the design stations,
and shall include information across the entire improved section from
tie slope to tie slope in order to document that the design ditch,
shoulder and roadway sections have been met.
(7) Parking spaces including handicapped spaces and access points.
(8) Retaining wall locations and elevations.
(9) Where permanent monuments have been set for right-of-way or tract
boundary, the four-decimal state plane coordinates and two-decimal
elevation of the center of the monument.
(10)
Building locations with tie distances to property lines.
(11)
Any improvement where setbacks from property lines to critical
points (building corners, etc.) have been shown on the approved plans.
(12)
Utility location in association with easements (i.e., is the
utility centered on the easement, etc.).
(13)
Field changes not otherwise required by this section.
(14)
Cross-section plots for any or all stations of the project may
be required, at the discretion of the Engineer.
(15)
Other information as deemed necessary by the Township Engineer,
depending on site conditions.
