**Construction Specification 702---Clearing and Grubbing**

**1. Scope**

The work consists of clearing and grubbing and disposal of trees, snags,
logs, brush, stumps, shrubs, and rubbish from the designated areas.

**2. Protection of existing vegetation**

Trees and other vegetation designated to remain undisturbed shall be
protected from damage throughout the duration of the construction
period. Any damages resulting from the contractor\'s operations or
neglect shall be repaired by the contractor.

Earthfill, stockpiling of materials, vehicular parking, and excessive
foot or vehicular traffic shall not be allowed within the drip line of
vegetation designated to remain in place. Vegetation damaged by any of
these or similar actions shall be replaced with viable vegetation of the
same species, similar condition, and like size unless otherwise approved
by the contracting officer.

Any cuts, skins, scrapes, or bruises to the bark of the vegetation shall
be carefully trimmed and local nursery accepted procedures used to seal
damaged bark.

Any limbs or branches 0.5 inch or larger in diameter that are broken,
severed, or otherwise seriously damaged during construction shall be cut
off at the base of the damaged limb or branch flush with the adjacent
limb or tree trunk. All roots 1-inch or larger in diameter that are cut,
broken, or otherwise severed during construction operations shall have
the end smoothly cut perpendicular to the root. Roots exposed during
excavation or other operations shall be covered with moist earth or
backfilled as soon as possible to prevent the roots from drying out.

**3. Marking**

The limits of the area(s) to be cleared and grubbed will be marked by
stakes, flags, tree markings, or other suitable methods. Trees to be
left standing and uninjured will be designated by special markings
placed on the trunk about 6 feet above the ground surface.

**4. Clearing and grubbing**

All trees not marked for preservation and all snags, logs, brush,
stumps, shrubs, rubbish, and similar materials shall be cleared from
within the limits of the designated areas. Unless otherwise specified,
all stumps, roots, and root clusters that have a diameter of 1 inch or
larger shall be grubbed out to a depth of at least 2 feet below subgrade
for concrete structures and 1 foot below the ground surface at
embankment sites and other designated areas.

**5. Disposal**

All materials cleared and grubbed from the designated areas shall be
disposed of at locations shown on the drawings or in a manner specified
in section 7. The contractor is responsible for complying with all local
rules and regulations and the payment of any and all fees that may
result from disposal at locations away from the project site.

**6. Measurement and payment**

***Method 1***---For items of work for which specific units prices are
established in the contract, the cleared and grubbed area is measured to
the nearest 0.1 acre. Payment for clearing and grubbing is made for the
total area within the designated limits at the contract unit price. Such
payment will constitute full compensation for all labor, equipment,
tools, and all other items necessary and incidental to the completion of
the work.

**Method 2**---For items of work for which specific unit prices are
established in the contract, the length of the cleared and grubbed area
is measured to the nearest full station (100 feet) along the line
designated on the drawing or identified in the specifications. Payment
for clearing and grubbing is made for the total length within the
designated limits at the contract unit price. Such payment will
constitute full compensation for all labor, equipment, tools, and all
other items necessary and incidental to the completion of the work.

***Method 3***---For items of work for which specific unit prices are
established in the contract, each tree, stump, and snag having a
diameter of 4 inches or larger and each log having a diameter of 4
inches or larger and a length of 10 feet are measured before removal.
The size of each tree and snag is determined by measuring its trunk at
breast height above the natural ground surface. The size of each log is
determined by measuring the butt and by measuring its length from butt
to tip. The size of each stump is measured at the top. Diameter is
determined by dividing the measured circumference by 3.14.

Payment for clearing and grubbing of each tree, stump, and snag having a
diameter of 4 inches or larger and each log having a diameter of 4
inches or larger and a length of 10 feet or larger is made at the
contract unit price for its size designation as determined by the
following schedule:

  ------------------------------------ ----------------------------------
  **Measured diameter\                 **Size designation\
  (in)**                               (in)**

  4 to 8                               6

  8 to 12                              10

  12 to 24                             18

  24 to 36                             30

  36 to 60                             48

  Over 60                              60
  ------------------------------------ ----------------------------------

The sum of such payments shall constitute full compensation for clearing
and grubbing (including the clearing and grubbing of smaller trees,
stumps, snags, logs, brush, shrubs, and roots), applicable permits and
associated fees, and rubbish removal. Such payment shall constitute full
compensation for all labor, equipment, tools, and all other items
necessary and incidental to the completion of the work.

***Method 4***---For items of work for which specific lump sum prices
are established in the contract, payment for clearing and grubbing is
made at the contract lump sum price. Such payment shall constitute full
compensation for all labor, equipment, tools, and all other items
necessary and incidental to the completion of the work.

***All Methods***---The following provisions apply to all methods of
measurement and payment. Compensation for any item of work described in
the contract, but not listed in the bid schedule will be included in the
payment for the item of work to which it is made subsidiary. Such items
and the items to which they are made subsidiary are identified in
section 7.

**7. Items of work and construction details**

Items of work to be performed in conformance with this specification and
the construction details are:

[Bid Item 1, Clearing and Grubbing]{.underline}

(1) This item shall consist of any clearing and grubbing of the wooded
    portions of the site necessary to complete the work as shown on the
    drawings.

(2) The cleared material will be burned and the remains buried or
    removed from the site and disposed of at locations selected by the
    contractor. Stumps, trash, vines, and other debris left from burning
    shall be buried in areas that will not be under planned structures.
    Any on-site burial locations will require approval by the Engineer
    or his representative. Buried material shall be covered with a
    minimum of two (2) feet of soil. The surface of the burial area
    shall be smoothed to blend with the surrounding topography.

(3) Any material hauled from the site for disposal will require a
    written and notarized statement from the owner of the disposal site,
    giving permission for the disposal and stating the Natural Resources
    Conservation Service will not be held responsible for any cost or
    damages occurring from the disposal.

(4) Heavy oils, asphaltic materials, items containing natural or
    synthetic rubber or any materials other than wood or plant growth
    shall not be burned.

(5) A portion of the cleared material may be used to construct a brush
    dam for trapping sediment from construction operations at locations
    selected by the engineer. If cleared materials are used for this
    purpose, they will be disposed of by methods detailed in paragraph 2
    or 3 above, after the disturbed areas are stabilized. Compensation
    for construction and maintenance of the brush dam will be provided
    under Bid Item 3, Pollution Control.

(6) Payment for clearing and grubbing shall be by Method 4.
