The Table of Contents for this section is available.
(A) General:
The work covered by this section consists of the excavation and satisfactory disposal of all materials excavated in the construction of ditches except silt ditches.
(B) Drainage Ditches:
Drainage ditches will be defined as inlet and outlet ditches for pipe culverts and structures, changes in channels of streams, ditches draining borrow and material sources, and parallel or lateral ditches when such ditches are separated from the roadway slope by an area of natural ground or berm.
Unless otherwise classified on the plans, parallel or lateral ditches constructed as an integral part of the graded roadbed, having a continuous slope from the outer limit of the shoulder to the bottom of the ditch, will be considered to be within the roadway grading limits and will be part of the work covered by Section 225.
(C) Berm Ditches:
Berm ditches will be defined as ditches constructed by either excavation or the construction of earth berms along the top of the cut slopes. The location of berm ditches will be as shown on the plans or as directed by the Engineer.
The excavation shall be done to the lines, grades, typical sections, and details shown on the plans or established by the Engineer. All work covered by this section shall be coordinated with the grading, construction of drainage structures, excavation of borrow and material sources, and other work along the project, and shall be maintained in a satisfactory condition so that adequate drainage is provided at all times. The ditches shall be maintained by the Contractor until the final acceptance of the project. Any roots which protrude into the ditch shall be trimmed flush with the sides of the ditch. Inlet and outlet ditches for pipe lines shall be completed before the pipe is installed unless otherwise permitted by the Engineer.
All excavated materials shall be utilized in the construction of roadway embankments except where otherwise directed by the Engineer. Materials which are excess to the needs of the project may be deposited alongside the ditch, and spread to form a low, flat, inconspicuous spoil bank of sufficient regular contour to permit seeding and mowing to be performed, provided no drainage into the ditch is blocked.
(A) Drainage Ditch Excavation:
The quantity of drainage ditch excavation to be paid for will be the volume in cubic yards, measured in their original position by the average end area method, of all materials excavated within the limits established by the plans or directed by the Engineer.
Where the Contractor has excavated beyond the above limits, no measurement will be made of such excavation.
(B) Berm Ditch Construction:
The quantity of berm ditch construction to be paid for will be the actual number of linear feet of berm ditch, measured along the flow line of the ditch within the pay limits shown on the plans, which has been completed and accepted.
(A) Drainage Ditch Excavation:
The quantity of drainage ditch excavation, measured as provided in Subarticle 2404(A), will be paid for at the contract unit price per cubic yard for "Drainage Ditch Excavation." Where the contract does not include the item of "Drainage Ditch Excavation," all work of drainage ditch excavation will be treated as unclassified excavation for pay purposes and will be paid for at the appropriate contract unit price per cubic yard.
(B) Berm Ditch Construction:
The quantity of berm ditch construction, measured as provided in Subarticle 2404(B), will be paid for at the contract unit price per linear foot for "Berm Ditch Construction."
(C) Compensation:
The above prices and payments will be full compensation for all work covered by this section including but not limited to excavation, shaping of the ditches, disposal of all materials, construction of earth berms, and the maintenance of the work in an acceptable condition until final acceptance. Payment will not be made for any overexcavation beyond the authorized neat lines established by the Engineer; nor for any drainage ditch excavation made solely for the convenience of the Contractor or for temporary drainage of the project; or for any excavation to provide drainage of borrow or material sources furnished by the Contractor.
(D) Pay Items:
Payment will be made under:
