PART 3 EXECUTION

3.1 MOWING

3.1.1 General

a. The dike system consists of approximately 42 miles of dikes at Savannah Harbor and 5 miles of dike at Andrews Island, with additional frontage roads. The areas to be mowed have both variable widths and slopes. In order to fulfill the requirement of this contract, specialized equipment must be used. Mowing the tops of the dikes shall be accomplished using a mowing machine pulled behind a tractor. Mowing all other areas, dike slopes and wet areas, shall be accomplished using a boom mower and/or batwing mower. The Contractor will furnish all labor and special equipment as required to accomplish this. All equipment used in the operation of mowing shall be adequate to produce the desired results.

b. Areas of mowing are to be cut a maximum of 5 inches above the ground except in areas where Love grass is dominant, where mowing shall be cut to a maximum of 10 inches above the ground. The Contractor shall keep the mowers in proper adjustment at all times in order to eliminate destroying the turf and/or leaving the vegetation above 5 inches. The Contractor shall ensure that mower blades are kept sharp at all times and all mowing equipment is in top running order. The vegetation shall be left in a cleanly cut condition. If the areas are not mowed satisfactorily on the first pass as a result of failure by the Contractor to maintain sharp blades, the Contractor will be directed to re-mow the area at no additional cost to the Government.

c. The Contractor shall perform all mowing operations in a manner which will prevent any spillage or leakage of fuel, oil, or any material that may contaminate the area. The Contractor shall clean up any contamination of the area caused during mowing.

SECTION 02 01 40 Page 11

d. At all weir locations, a 16-foot width access path shall be mowed or cut to the outlet end of the weir pipe. The access path to each weir catwalk shall be mowed the same as the dike. The cost for this will be included in the mowing of the containment area.

3.1.2 Equipment

The Contractor shall use equipment that will not destroy the integrity of the dike. Equipment used shall not be permitted to operate on slopes that are too steep or sandy and that will cause rutting of slopes. The Contractor shall restore all damage to the top of dikes, slopes, shoulders, or roads caused by the Contractor, to their original condition. On slopes that are too steep for equipment, a boom mower will be required. Also, there are areas within the limits of mowing that are wet and/or pond water for extended periods of time which will require use of a boom mower.

3.1.3 Order of Work

Order of work shall be determined by the Contracting Officer. Mowing of the top of dikes, slopes, underdrain ramps, access ramps, access shoulders, etc. shall be completed and accepted per containment area unless otherwise directed by the Contracting Officer.

3.1.4 Extent of Mowing

a. Mowing shall consist of mowing of all dikes, dike slopes, access ramps, under drain station ramps, weir access ramps, weir outfall accessories, etc. In accordance with the August 1996 U.S. Corps of Engineers Environmental Impact Study, the dike roads and 5' down the inside and outside slopes may be mowed during the non-mowing season defined as April 1 to July 15. Mowing season is defined as July 16 to March 31. Grass will be taller after this period of time and will require more time to be mowed. Avoid all bird nests at all times.

b. In addition to the dikes, the Contractor shall be required to mow the access road along the front of Areas 12A and 14A and an open area adjacent to the tide gate structure on the South Carolina side of the Back River. This mowing will consist of mowing the shoulders and back slope approximately 10 feet on each side of the road. Inside of curves will be 15 feet.

c. Area 2A, located on Hutchinson Island, may be accessed by water or land. To access Area 2A by land requires crossing property owned by International Paper Company. Permission to cross International Paper Company's property will be the responsibility of the Contractor. The Government will assume no responsibility nor arrange for the Contractor to have access to this disposal area across the property owned by International Paper Company. The Contractor may use a barge at his own expense.

d. The Contractor may be required to mow an area at the outside toe of the dike and/or all or portions of the interior of any of the disposal areas. Estimated quantities are shown in Table 1.

3.2 REPAIR OF DIKES

3.2.1 General

Settled and/or eroded areas of the dikes, including the tops and both side slopes, shall be repaired with satisfactory materials borrowed from the approved locations within the disposal areas. Satisfactory materials shall consist of SW, SP, SM, SC, CL, CH, ML, MH and OH materials as classified in ASTM D 2487. The Contractor shall haul the borrow material to the eroded sites and spread it uniformly in the area(s) designated for repair. The material shall be spread and compacted with equipment by passing over it a minimum of five times. All material determined by the Contracting Officer to be too wet or too soft to provide a stable compacted fill will be classified as unsatisfactory regardless of classification. The Contracting Officer shall approve satisfactory material before the repairs are made.

Stone larger than 6 inches in diameter shall not be permitted in satisfactory material for erosion repairs. All eroded material deposited at the bottom of the dikes shall be removed to the extent practical and reused to match the original section. The borrow materials may be obtained from any disposal area as approved by the Contracting Officer. The Contractor shall conduct his borrow operations to the extent practical which will allow surface water to drain from the borrow location to the weirs. All repaired areas of the dike shall be grassed and mulched in accordance with SECTION: GRASSING (SEEDING).

3.2.2 Erosion Control

Areas of the dikes and adjacent bank that have been eroded as a result of wave action may require rock placement to prevent further erosion. Dikes will be repaired as specified in paragraph REPAIR OF DIKES, subparagraph General with the exception of grassing and mulching in areas that require rock placement. Rock shall be placed as shown on Plate D-1 or as directed by the Contracting Officer. The Contractor shall be responsible for maintaining haul roads at his own expense during the period of hauling operations. The Contractor is responsible for returning all roads utilized for hauling to their original condition and elevations that existed prior to hauling operations upon completion of the work unless otherwise directed by the government. The government is not responsible for lost time in hauling operations due to the Contractor's negligence in maintaining roads in a passable condition.

3.3 GRADING

The Contractor shall be required to use a motor grader to smooth and/or grade the top of the dikes and the access road from the disposal area entrance gate near US Highway 17 to the Screven Ferry Road dredge laydown area. The table in Subparagraph Estimated Quantity lists the perimeter of each disposal area. Additional grading may be required at other locations providing access to the existing dredged material disposal areas.

3.4 CLEARING, GRUBBING, AND BURNING

The Contractor shall be required to perform clearing and grubbing operations. It is anticipated that this work will be performed using a dozer, excavator, long-reach excavator, stout bush hog (tree cutter), dump truck, or any combination thereof. Grubbing, when specified in the task order, shall be performed with the dozer using a root rake. The cleared

SECTION 02 01 40 Page 14 and grubbed material shall be placed at the direction of the Contracting Officer's Representative within the disposal area designated for clearing and grubbing and shall be burned. All cleared and grubbed materials shall be burned to the fullest extent possible and buried within the disposal area. The Contractor shall be responsible for any damage to life and/or property resulting from fires that are started by his employees or as a result of his operations. The Contractor shall excavate a pit for burying the burned material, place the burned material in the pit, and cover the burned material with a minimum of two feet of cover. The Contractor shall ensure that excavation and burning operations do not damage underdrains in the disposal area. Any underdrains damaged as a result of the Contractor's negligence shall be repaired at no cost to the Government. The cover material shall be obtained from existing dredged material located adjacent to the disposal pit. The Contractor shall ensure that the cover is placed no higher than the elevations adjacent to the disposal pit. The Contractor shall be responsible for coordinating burning operations and for obtaining any and all permits for burning as may be required by Federal, State, and local government agencies prior to commencement of burning operations.

Suitable Air Curtain Burners / Destructors or trench Air Curtain burners shall be used unless specifically waived in writing by the COR and is permitted in accordance with Federal, State, and local regulation.

3.5 DITCHING

Ditching and dewatering operations will be conducted as directed by the Contracting Officer's Representative (COR) within the disposal areas shown on the drawings. Work will consist of removal of previously placed material in front of the weirs, excavation of sumps in front of each weir, and ditching of hydraulically placed dredged material inside the disposal area. Ditches shall be excavated around the inside perimeter and across the disposal areas. Existing material in the disposal area is recently deposited dredged material consisting primarily of silts, sand, and clay.

This material has been deposited since the aerial photographs were taken.

Mats will be required in areas. The construction of access ramps inside the dikes will be the Contractor's responsibility. Ditching shall be performed along the inside of the dike and at locations as directed by the COR. The excavator shall begin ditching as directed by the COR. To establish sumps, material shall be excavated from in front of all weirs in the disposal areas and carefully deposited either further away from the weirs or on the lower 5 feet of the inside slope of the dike. Excavated material deposited in the interior of the disposal area shall be placed in such a manner as to allow surface runoff from the interior to flow to the ditches. The material shall be spread to prevent mounding unless directed otherwise by the Contracting Officer Representative. Care shall be taken not to remove any material from the adjacent dike or cause any damage to the dikes or weirs.
