HomeMy WebLinkAbout12 45-01SP Construction DetailsGENERAL NOTES:
1. All sanitary sewer construction on this project may be of P.V.C. sewer pipe (SDR 26 or
SDR 35) conforming to A.S.T.M. Specification C- 700 -71T. At owner's option Type P.
S.M. polyvinylchloride sewer pipe and fittings Type 1, Grade conforming to
A.S.T.M. Specifications D -3034 or Acrylonitril e—Bu tadiene— Styrene
(ABS) sewer pipe conforming to A.S.T.M. D- 2680 -79A may be substituted. Joints
in all pipe shall conform to A.S.T.M. Specification C- 425 -71. All subsequent
A.S.T.M. revisions shall apply or as specified on plans.
2. All storm sewers shall be constructed with reinforced concrete pipe Class III
or as noted and conform to A.S.T.M. C -76 or latest revision. All manholes
shall be precast concrete construction in accordance with State of Indiana
Specifications and shall have Type "A" cast iron ring and cover.
3. Joints in sewer pipe shall conform to A.S.T.M. Specification C -425 or latest
revision.
4. Sewer pipe shall be bedded in accordance with detail shown. Sewer trenches
shall be kept free of all water. Do not allow water or mud to enter the
sewer.
5. All sanitary sewer lines upon completion will be required to pass a low
pressure air test, unless otherwise directed by the City Engineer. Said test
shall be conducted according to NCPI Standard Method, and shall be witnessed
by the City Inspector. Infiltration under test shall not exceed 200 gallons
per inch of inside diameter of sewer pipe per mile of sewer in 24 hours and
inclusive of all appurtenances within the section being tested such as
manholes, house connections, etc.
6. All pipe or drainage structures in trenches under paved surfaces and within 10
feet of the pavement shall be backfilled with granular material and compacted
by approved methods.
7. No roof drains, footing drains and / or surface water drains may be connected
to the sanitary sewer system, including temporary connections during
construction.
8. All lots are to be served by 6" sanitary sewer pipe of P.V.C. or
alternate material approved by the City Engineer. These laterals are to be
carried approximately to the property line, and the location of their
termination indicated on the surface with a suitable marker. The Wye is to
be tilted up at 45 degrees from the horizontal and the end plugged tight
with clay or plastic disc, capable of withstanding a low pressure Air Test
without leakage. The lateral locations should also be marked with red on the
curb. Mandrel test is required on all main line sewers per Indiana State
Board of Health.
9. Sewers crossing mains shall be laid to provide minimum distance of 18 inches
between the outside of the water main and the outside of the sewer. This shall
be the case where the water main is either above or below the sewer. The
crossing shall be arranged so that the sewer joints will be equidistant and as
for as possible from the water main joints. Where a water main crosses under
a sewer, adequate structural support shall be provided for the sewer to
prevent damage to the water main. When it is impossible to obtain proper
horizontal and vertical separation as stipulated above, the sewer shall be
designed and constructed equal to water pipe and shall be pressure tested to
assure watertightness prior to backfilling.
10. Water mains shall be of ductile iron Class 350 cement lined pipe, unless
otherwise noted in the plans.
A. Water lines shall be of ductile iron pipe, Class 50 cement
line water works grade.
B. Stop shall be those manufactured by Ford or Mueller Corporation with AWWA
taper thread, and with copper compression type fitting on outlet, or
equal.
C. Blow —off valves shall be those manufactured by Mueller Corporation
(HO10283 or H- 10291), or equal.
D. Angle valves at the end of water service stub are to be copper compression
type fitting also, and are to be protected with plastic bay over the
valve.
E. 3/4" taps in lines smaller than 4 inches shall be only by tapped tee or
tapping saddle. Water service lines should be marked on curbs with blue
paint. (Sewer lateral locations — red).
11. All water mains to be pressure tested for leakage and sterilized in
accordance with directions from Carmel Water Department.
12. No traffic will be allowed on prepared subgrade prior to paving.
13. All street construction within the lines of dedicated right —of —way shall be
in accordance with the Specifications of City of Carmel.
14. Property line corners of street intersections are rounded by an arc having
a 15' radius. Property lines drawn hereon are carried to the P.I. of the
arc.
15. A temporary seeding mixture in the areas where stripping of fills have been
graded shall be seeded for silt and erosion protection. After grading all
construction areas are to be seeded as follows:
A. Swale seeding : Seed and fertilize within construction limits with 5# /acre
"Redtop" grass, 20# /acre "Rye Grass', 20# /acre "Blue Grass ", 25# /acre
"Tall Fescue" grass, and 600# /acre 12 -12 -12 fertilizer.
B. Cut /Fill Seeding Along Paved Areas: Seed and fertilize with 25# /acre "Tall
Fescue" grass, 20# /acre "Rye Grass ", 15# /acre "Blue Grass" and 600# /acre
12 -12 -12 fertilizer.
16. The location of houses (depicted by rectangles) show the pad elevation and /or
outside grade. The finished floor elevation is 8 inches higher, more or less
than the outside grade.
17. It shall be the responsibility of each contractor to verify all existing
utilities and conditions pertaining to his phase of the work. It shall also
be the contractors responsibility to contact the owners of the various
utilities before work is started. The contractor shall notify in writing the
owners and /or the engineers of any changes, errors, or omissions found on
these plans or in the field before work is started or resumed.
18. All drainage pipe and ditch outfolls to receiving streams shall be
constructed in accordance with drawings, subject however, to any modification
required by the City of Carmel at the time installation is completed and to
any adjustments needed for field conditions that could not be anticipated on
the design drawings.
19. Contractor to record dimensions measured along sewer line from nearest
manhole to each sanitary sewer lateral.
20. Contractor to record dimension of each water stub from nearest fire hydrant
measured along the water main.
21. The above locations of laterals, along with any other construction changes
are to be incorporated on the original construction drawings and record
drawings submitted to the City Engineer's Office as soon after completion of
construction as possible.
22. Contractor shall verify subsurface conditions prior to bidding.
23. "The engineer and /or owner disclaim any role in the construction means and
methods associated with the project as set forth in these plans."
