unsatisfactory material at any time during the process of selection,
delivery, installation period.
a)The Contractor shall bear all costs related to plant rejections
due to failure of the review process.
b)All plants rejected shall be immediately removed from the
site and acceptable plants should be provided in a timely fashion
that does not interfere with Project scheduling.
1.4 DELIVERY, STORAGE, AND HANDLING.
A.Trees and Shrubs: Do not prune trees and shrubs before delivery,
except as approved by Owner's Representative. Protect bark,
branches, and root systems from sun scald, drying, sweating,
whipping, and other handling and tying damage. Do not bend or
bind-tie trees or shrubs in such a manner as to destroy their natural
shape. Provide protective covering of plant material during delivery.
Take necessary steps to avoid dropping plant material during delivery.
Handle all container grown and/or balled and burlapped stock by the
root ball.
B.Deliver all plant material after preparations for planting have been
completed and install immediately. If planting is delayed more than 6
hours after delivery, set plants in a location protected from sun, wind,
and mechanical damage. Keep all plant material well-watered during
the storage period.
1.Do not remove container-grown stock from containers before time
of planting.
2.Cover balled and burlapped stock with soil, peat moss or other
acceptable materials to keep from drying out.
3.Water root systems of all plant material stored on-site with a fine
mist spray. Water as often as necessary to maintain root system in
a moist condition.
C.Sod: Time delivery so that sod will be placed within 24 hours after
stripping. Protect sod against drying and breaking.
D.Seed and Other Packaged Materials: Deliver packaged materials in
original, unopened containers showing weight, certified analysis, name
of manufacturer. Seed specifically shall label with variety of seed,
percentage of germination, and weed content.
E.Bulk Materials:
1.Do not dump or store bulk materials near structures, utilities,
walkways and pavements or on existing turf areas or plants.
2.Provide erosion control measures to prevent erosion or
displacement of bulk materials, discharge of soil bearing water
runoff, and airborne dust reaching adjacent properties, water
conveyance systems, or walkways.
F.Contractor is responsible for keeping project site clean and disposing
of delivery / packaging materials on an as needed basis to keep an
orderly appearance.
1.5 PROJECT CONDITIONS
A.Utilities: Contractor shall verify actual grade elevations, service and
utility locations, irrigation system components, and location of any
other construction elements adjacent to location of new plantings prior
to proceeding with planting work.
1.Contractor is responsible for knowing and avoiding the location of all
utilities. For dig-a-line services call toll free 1-800-422-4133 or the
State's local number, at least two working days before installation
begins.
2.Contractor shall work in such a manner to avoid possible damage to
existing utilities. Hand excavate as required. Maintain grade stakes
until removal is mutually agreed upon by parties concerned.
3.Do not interrupt services or utilities to facilities occupied by Owner
unless with prior written approval from Owner's Representative.
B.Adjacent Landscape: Protect planted areas adjacent to construction
work. Replace or recondition to prior conditions prior to project
completion.
C.Grading: Any berming and grading shown on plans shall have gradual
transitions to existing or engineer proposed grades. Fine grading shall
not change flow direction of surface drainage or swales as shown on
engineering plans.
1.6 SEQUENCING
A.Planting Time: Proceed with landscape installation as portions of the
site become available, working within seasonal limitations for the type
of landscape work required.
1.Install planting material during normally accepted planting season
between March 15 and November 15.

Substantial Completion.
2.Warranty Period for Ornamental Grasses / Perennials: 12 months
from date of Substantial Completion.
3.Warrant Period for Lawns: through specified maintenance period.
4.At minimum, warranty replacement shall include removal of dead or
unhealthy plant material during warranty period. Replace trees and
shrubs which are in unhealthy condition at or before the end of
warranty period, unless directed by Owner's Representative that it is
