1.6.4.
1.6.5.
1.6.6.
The Owner shall be compensated per requirements specified in the schedule below for
all trees and shrubs damaged or destroyed. Compensation shall be deducted from
Contractor's progress payments.
Injury is defined, without limitation, as all bruising, scarring, tearing, or breaking of roots,
branches, or trunk, as defined by Architect.
It is and will be impracticable and difficult to determine the actual damage, whether
physical or aesthetic for existing planting materials. Therefore, the Owner has assigned
a total value to a tree or shrub based on its diameter at 30 inches above the ground.
The total value shown shall be paid to the Owner for a tree or shrub totally destroyed.
For injuries to roots or branches the Owner will assign a value proportional to the total
value of the tree or shrub.
Proportional amount of the total value shown shall be paid to the Owner, for each tree or
shrub injured, as follows:
1.6.6.1.
1.6.6.2.
1.6.6.3.
1.6.6.4.
1.6.6.5.
Measure the diameter of the tree or shrub at 30 inches above grade level.
Multiply the diameter by 3.14 to get the circumference (or, with a tape
measure, measure distance around the tree or shrub).
Divide the total value of the tree or shrub per schedule established below by
its circumference at 30 inches above grade to determine a value per inch of
circumference (value of tree or shrub divided by circumference equals value
per inch).
Measure the length of the injury.
Multiply the length of the injury by the value per circumferential inch; the
result is the amount of compensation for each injury (length of injury
multiplied by value per inch equals compensation).
Example:
1.6.6.5.1. A tree with a diameter of 17 inches at 30 inches above grade is
valued at $20,000.
1.6.6.5.2. Circumference at that point: 17 multiplied by 3.14 equals
53.38 inches.
1.6.6.5.3. Value per inch of 17 inch diameter tree: $20,000 divided by
53.38 inches equals $374.67.
1.6.6.5.4. Injury is 12 inches in length.
1.6.6.5.5. Compensation for injury: 12 multiplied by $374.67 equals
$4,496.04.
