NOTES
Refer to separate specifications manual for additional project requirements.
SCHEDULE
Contractor shall complete grading of these facilities within 60 days of the notice to proceed.
Landscaping must proceed as soon as possible after final grading but within specified time periods.
SURV EY
Benchmarks used to develop- the sitemap have been identified - on the plans. Information for these benchmarks will be provided by the Construction Manager. Otherwise contractor will provide any needed survey equipment,
materials and personnel to insure the project is constructed to meet lines and grades as specified.
SOIL MATERIALS
It is anticipated that all suitable soil materials required to complete the project are present on site. Replacement
of unsuitable materials will be paid on basis of conditions of Contract relative to changes in work.
EXCAVATION
Excavation consists of removal of material encountered to subgrade elevations indicated on
cross sections and subsequent disposal of materials removed.
Contact the Indianapolis Water Co. regarding the location of water lines in the vicinity. Avoid any damage.
Contractor is responsible to repair damaged utilities to satisfaction of utility owner. Should uncharted
piping or other utilities be encountered during excavation, consult utility owner immediately for directions.
Perform excavation work in compliance with authorities having jurisdiction.
Subgrade: The undisturbed earth or the compacted soil layer immediately below topsoil materials.
Prior to excavation/grading mow existing vegetation throughout the work area to 3 inches
or less in height, as needed. Remove vegetation in area of excavation. Avoid any vegetation
disturbance in existing wetland. Install temporary silt fence along boundary of existing wetland
as shown on plans and details.
Excavate and separate the top 6" of soil from the rest of the soil excavated. (When backfilling,
this separated topsoil will be replaced last). Then excavate subgrade to 6" below final
grade, so that lines and grades meet specified grades after topsoil replacement.
Unauthorized excavation consists of removal -of materials beyond indicated subgrade elevations on
cross sections dimensions without specific direction of the Construction Manager. Unauthorized excavation, as well
as remedial work directed by the Construction Manager shall be at Contractor's expense.
Backfill and compact unauthorized excavations as specified for authorized excavations of same
classification, unless otherwise directed by the Construction Manager.
Additional Excavation: When excavation has reached required. subgrade elevations, notify the
-----Construction-Manager,-who-will-make-aninspection--of-conditions.If-theConstruction-Manager-determines ---
that subgrade elevations are unsuitable, continue excavation or backfill until subgrade elevations and drainage
conditions are approved. The Contract Sum may be adjusted by an appropriate Contract Modification.
Removal of unsuitable subgrade material and its replacement as directed (other than that specified)
will be paid on basis of Conditions of the Contract relative to changes in work.
GRADING

surface by providing uniform levels or slopes between points where elevations are indicated or
between such points and existing grades.
Protection of Graded Areas: Protect newly graded areas from traffic and erosion. Keep free of trash and
debris.
Repair and reestablish grades in settled, eroded, and rutted areas to specified tolerances.
Reconditioning Compacted Areas: Where completed compacted areas are disturbed by subsequent
construction operations, flooding or adverse weather, scarify surface, reshape, and compact to required
density prior to further construction.
TOPSOIL AND FINAL GRADING
Loosen subgrade to a minimum depth of 4 inches. Remove stones measuring over 1-1/2 inches in any
dimension. Remove sticks, roots, rubbish, trash, and other extraneous matter to a depth of not less
than 4 inches. Spread topsoil to 6" minimum depth. Final grade after topsoil placement required to
meet lines, grades, and elevations shown, after light rolling and natural settlement. Pack the
seedbed firmly with a roller or log sled. Remove ridges and fill depressions, as required
to meet finish grades.
WATER LEVEL CONTROL STRUCTURE PIPES AND APPURTENANCES
Install water level control structure, pipes and appurtenances according to drawing.
Use PVC riser pipe and elbow of the same size and quality of existing drain pipe or better.
All joints must be water tight.
Install Bar Guard as available from Agri -Drain Corporation (1-800-232-4742) or equivalent
(approved by Construction Manager).

LANDSCAPING
The Construction Manager shall be notified, prior to beginning planting operations.
Ship landscape materials
with certificates of inspection required by governing
authorities.
Do not allow delivery
of seed to the site more than one week prior to
installation. Store in a cool dry location prior to installation.
Provide fresh, clean,
new -crop seed complying with tolerance for purity and
germination established by Official Seed Analysts of North America. Provide seed
mixture composed of
grass and other species in the proportions specified.
The following Wetland
seed mix will be planted in the area of grading, as available from
Heartland Restoration
Services (219.489.8511). The mix will be formulated & installe.d at
a rate of 13,800,000

Do not make substitutions. If specified landscape material is not obtainable,
submit proof of non -availability to the Construction Manager, together with proposal for
use of equivalent material. No reduction in quantity will be accepted.
