3.06 Planting Trees and Shrubs:
A. Set balled and burlopped stock plumb and in center of it or trench with top of
ball raised above adjacent finish grades as indicated.
1. Place stock on setting layer of compacted planting soil.
2. Remove burlap and wire baskets from tops of bolls and partially from sides, but
do not remove from under balls. Remove pallets, if any, before setting. Do notuse
planting stock if ball is cracked or broken before or during planting operation.
3. Place backfill around ball in layers, tamping to settle backfill and eliminate voids
and air pockets. When pit is approximately 1h backfilled, water thoroughly before
placing remainder of backfill. Repeat watering until no more is absorbed. Water
again after placing and tamping final layer of backfill.
B. Set contain er-grown stock plumb and in center of pit or trench with top of ball
raised above adjacent finish grades as indicated.
1. Carefully remove containers so as not to damage root balls.
2. Place stock on setting layer of compacted planting soil.
3. Place backfill around ball in layers, tamping to settle backfill and eliminate voids
and air pockets. When pit is approximately % backfilled, water thoroughly before
placing remainder of backfill. Repeat watering until no more is absorbed. Water
again after placing and tamping final layer of backfill.
C. Dish and tamp top of backfill to form a 3 inch (75 mm) high mound around the
rim of the pit. Do not cover top of root ball with backfill.
D. Wrap trees of 2 inch (50 mm) caliper and lorger with trunk-wrap tape. Start at
base of trunk and spiral cover trunk to height of first branches. Overlap wrap,
exposing half the width, and securely attach without causing girdling. Inspect tree
trunks for injury, improper pruning, and insect infestation and take corrective
measures required before wrapping.
3.07 Tree and Shrub Pruning:
A. Prune, thin, and shape trees and shrubs as directed by Landscape Architect.
3.08 Tree and Shrub Guy Staking:
A. Upright Staking and Tying: Stake trees of 2 through 5 inch (50 through 125
mm) caliper. Stake trees of less than 2 inch (50 mm) caliper only as required to
prevent wind tip-out. Use a minimum of 2 stakes of length required to penetrate
at least 18 inches (450 mm) below bottom of backfilled excavation and to extend at
least 73 inches (1800 mm) above grade. Set vertical stakes and space to avoid
penetrating balls or root mosses. Support trees with 2 strands of tie wire encased
in hose sections at contact points with tree trunk. Allow enough slack to avoid rigid
restraint of trees.
B. Guying and Staking: Guy and stake trees exceeding 14 feet (4.2 m) and more
than S inch (75 mm) caliper unless otherwise indicated. Securely attach no fewer
than 3 guys to stakes 30 inches (760 mm) lo,ig, driven to grade. Attach flags to
each guy wire, 30 inches (760 mm) above finish grade. Wrap trunk with tape as
shown on details.
3.09 Planting Ground Cover and Plants:
A. Space ground cover and plants as indicated.
B. Dig holes large enough to allow spreading of roots, and backfill with planting soil.
Work soil around roots to eliminate air pockets and leave a slight saucer indentation
around plants to I-old water. Water thoroughly after planting, taking care not to
cover plant crowns with wet soil.
3.10 Fill:
A. Preparation: Remove vegetation, topsoil, debris, wet and unsatisfactory soil
materials, obstructions, and deleterious materials from ground surface prior to placing
fills.
B. When subgrade or existing ground surface to receive fill has a density less than
that required for f'll, break up ground surface to depth required, pulverize,
moisture-condition or aerate soil and recompact to required density.
C. Place fill material in layers to required elevations for each location listed below.
1. Under gross, use satisfactory excavated or borrow soil material.
D. Place fill matericls in layers not more than 8 inches (200 mm) in loose depth for
material compacted by heavy compaction equipment, and not more than 4 inche!;
(100 mm) in loose depth for material compacted by hand-operated tampers.
E. Place backfill and fill materials evenly on all sides of structures to required
elevations. Place backfill and fill uniformly along the full length of each structure,
F. Percentage of Moximum Dry Density Requirements; Compact soil to not less than
the following percentages of maximum dry density according to ASTM D 1557:
1. Under lawn or unpaved areas, compact the top 6 inches (150 mm) below
subgrode and each layer of backfill or fill material at 80 percent (80%) maximum dry
density.
3.11 Grading:
A. General: Uniformly grade areas to a smooth surface, free from irregular surface
changes. Comply with compact requirements and grade to cross sections, lines, and
elevations indicated.
1. Provide a smootl� transition between existing adjacent grades and new grades.
2. Cut out soft spcts, fill low spots, and trim high spots to conform to required
surface tolerances.
B. Site Grading: Siope grades to prevent poncling. Finish subgrades to required
elevations within 1h".
3.12 Final Grading end Placement of Topsoil:
A. Loosen subgrade and lawn area to a mininium depth of 4 inches. Remove stones
measuring over 1-12 inches in any dimension. Remove sticks, roots, rubbish, and
other extraneous matter. Limit preparation to areas which will be planted promptly
after preparation.
1. Spread topsoil to minimum depth required to meet lines, grades, and elevations
shown, after light rolling and natural settlement. Minimum depth of topsoil shall be
4 inches unless otherwise indicated. In tree and shrub planting areas there shall be
18" - 24" topsoil. Around the plant, at least in on area equal to the plants'
mature canopy size.
2. Place approximately % of total amount of topsoil required. Work into top of
loosened subgrade to create a transition layer and then place remainder of topsoil.
3.13 Reconditioning Lawn and Seeding of Berms:
A. Recondition existing lawn areas or other Contractor's work damaged by operations,
including storage of materials or equipment and movement of vehicles. Seed all
berms installed by Landscape Contractors that ore not in an existing lawn. Sod all
berms installed by Landscape Contractor that are in existing lawns.
B. Remove sod and vegetation from damaged lawn areas; do not bury into soil.
i
Remove topsoil containing foreign moterio;s resulting from Contractor's operat I ons,
including oil drippings, fuel spills, stone, gravel, and other construction materials, and
replace with new topsoil.
C. Where substantial lawn remains, mow, dethatch, core aerate, and rake. Remove
weeds before seeding. Where weeds are extensive, apply selective herbicides as
required. Do not use pre-emergence herbicides.
D. Remove waste and foreign materials, including weeds, soil cores, gross, vegetation,
and turf, and legally dispose of it off the Owner's property.
E. Till stripped, bare, and compacted areas thoroughly to a depth of 6 inches (150
mm).
F. Apply initial fertilizers and mix thoroughly into top 4 inches (1000 mm) of soil.
Fertilizer shall provide 1 lb. Per 1,000 sq. ft. of actual nitrogen, 4 percent (4%)
phosphorous, and 2 percent (2%) potassium by weight. Provide new planting soil as
required t fill low spots and meet new finish grades.
G. Apply sod, or seed and mulch as stated in Section 621.05 and 621.06 of the
1999 Indiana Department of Transportation Standard Specification.
H. Water newly planted areas and keep moist until new gross is established.
1. This work is not paid for directly but is included in the cost of other items.
3.14 Mulching:
A. Mulch backfilled surfaces of pits, trenches, planted areas, and other areas
indicated.
B. Organic Mulch: Apply the following average thickness of organic mulch and finish
level with adjacent finish grades. Do not place mulch against trunks or stems.
1. Thickness: 3 inches (75 mm).
3.15 Cleanup and Protection:
A. During landscaping, keep pavements clean and work area in an orderly condition.
B. Protect landscaping from damage due to landscape operations, operations by
other contractors and trades, and trespassers. Maintain protection during installation
"
and maintenance periods. Treat, repair, or replace damaged landscape work as
directed.
3.16 Disposal of Surplus and Waste Materials:
