maximum allowable pipe strength per ASTM and manufac-
turer's requirements. If additional pipe strength is
required for the probable earth live load condition,
the Contractor shall use a higher strength or bedding
method to satisfy the conditions.
C. Where shown on plan, use high density Polyethylene
(HDPE) Corrugated pipe with smooth interior (N
0.012). Pipe and fittings which meet or exceed the
requirements of Type III, Category 4 or 5, Grade P33 or
P34, Class C bedding per ASTM D1248. Joints shall be
split corrugated couplings at least 7 corrugations wide
and exceeding the soil tightness requirements of AASHTO
standard specifications for Highway Bridges, Section 23
(2.23.3). Backfill and installation shall comply with
manufacturer's recommendations.
4. Subdrainage system shall be installed as shown on Plans and
be of pipes designated in Section 906 of IDHSS as follows:
Pipes to be installed for subsurface drainage only may be
one of the following:
A. Perforated corrugated drainage pipe in accordance with
AASHTO M252 or AASHTO M294. PVC shall have minimum
cell classification conforming to requirement of
12454-C ASTM D-1784.
B. Concrete drain the in accordance with AASHTO M178.
C. Vitrified clay the in accordance with AASHTO M179.
Where pipe is to be used for a collector of other subsurface
laterals and/or sump pumps and installed with provisions for
cleaning, it may be one of t}te following:
A. ABS or PVC composite in accordance with ASTM D-2680.
B. PVC in accordance with ASTM D-3034 SDR -35.
C. Pvc corrugated with smooth interior in accordance with
ASTM F949.
5. Backfill around all structures and cuts under paved areas
and within five (5) feet of pavement edges with granular
material in accordance with Section 211 of IDHSS.
b. See standard detail sheet for construction dimensions of
storm structures. Manholes, inlets and catch basins shall
be in accordance with Section 720 of IDIISS. Precast con-
crete and steel for manholes and inlets shall be in accord-
ance with ASTM C-478, latest revision. Steps shall be
ductile iron or aluminum integrally cast into each catch
basin sidewalls.
7. The Contractor shall provide a minimum of one (1) foot of
earth cover over all storm sewers. If pipe is to have
construction traffic over it, Contractor shall provide a
minimum temporary earth cover of four (4) feet, until con-
struction period is complete. After completion of opera-
tions requiring construction traffic over pipe, Contractor
shall remove the temporary earth cover and grade the earth
to elevations shown on the Plans.
Rip -rap particles shall be a minimum of 6" and a maximum of
17" in size and shall be placed a minimum of 18" in depth.
Dimensions for rip -rap on this plan are for estimating
purposes only. Actual best placement of rip -rap shall be
determined by field conditions and shall be in accordance
with Section 616 of IDHSS.
9. All drainage pipe and ditch outfalls to receiving streams
shall be constructed in accordance with drawings, subject
however, to any modification required by Engineer at the
time of installation is completed and to any adjustments
needed for field conditions not adequately anticipated by
the design drawings.
10. Castings shall be as shown on detail sheet for manufacturer,
type and number. All castings shall be Neenah or East
Jordan approved equal. Castings shall be gray iron meeting
ASTM A-48, latest revision.
11. Install gaskets in accordance with manufacturer's recommen-
dations for use of lubricants, cements and other special
installation requirements.
12. Place plugs in ends of incomplete piping at end of work day
or whenever work stops, and at stubs for. future development.
13. Carry depth of trenches for piping to establish indicated
flow lines and invert elevations. Notch under pipe bells
where applicable to provide solid bearing for entire body of
pipe.
14. Trenching: Lay all pipe in open trenches, except when the
local authority gives wriften permission for tunneling.
Open the trench sufficiently ahead of pipe -laying to reveal
any obstructions. The width of the trench shall be the
outside pipe diameter plus nine (9) inches each side for 12
inches above the pipe or 0.3 x O.D., whichever is greater.
Sheet and brace trench as necessary to protect workmen and
adjacent structures. All trenching is to comply with Occu-
pational Safety and Health Administration standards. Con-
tractor shall employ a Registered Professional Engineer to
design trench safety systems for all trenches over twenty
(20) feet in depth. Keep trenches free from water while
construction is in progress. Under no circumstances lay
pipe or appurtenances in standing water. Conduct the
charge from trench dewatering to drains or natural drainage
channels.
15. All pipes on steep slopes (over 208) shall have concrete
anchors at maximum 40 feet intervals as shown on detail.
16. Backfilling: For a depth �f at least 12 inches above the
top of the pipe, backfill with earth or granular material
free from large stones, roc)r fragments, roots or sod. Tamp
this backfill thoroughly, taking care not to disturb the
pipe. For the remaining trench depth, backfill with earth
or granular material which May contain stones or rocks not
larger than four (4) inches. Backfill under walks, parking
areas, driveways and streets shall be granular material only
and shall be thoroughly compacted by approved methods to the
density specified. Trenches parallel to and within five (5)
feet of paved roadways shall be constructed the same. All
granular backfill shall be compacted to 958 Standard Proctor
maximum dry density. .
