Section 246 Section 246 will be measured end-to-end along the cross- section of the ditch in accordance with the erosion control drawing.
246.05 Basis of Payment. Sandbags and rockbags, measured as prescribed above, will
be paid for per linear foot or each, which pr ices shall be full compensation for furnishing bags, fine aggregate, size 57 aggregate, placement of bags, maintenance of the installation, removal and disposal of the sediment deposits and removal after construction has been completed, and for all labor, tools, equipment and incidentals necessary to complete the work. Payment will be made under: 246-A: Sandbags - per linear foot or each 246-B: Rockbags - per linear foot or each SECTION 247 - TEMPORARY STREAM DIVERSION
247.01 Description . Temporary stream diversion shall consist of excavating,
stockpiling excavated material, and constructing a stream diversion at a new/existing drainage structure. It shall also include preparation of the diversion stream’s bottom and slopes in accordance with the erosion control drawings.
247.02 Materials. Geotextiles of the type specified shall meet the requirements of
Subsection 714.13. Riprap of the size specif ied shall meet the requirements of Section 705.
247.03 Construction Requirements. Temporary stream diversion(s) will be
constructed in accordance with the erosion control drawings. During the excavation of the stream diversion, all excavated material shall be stockpiled and used to backfill the stream diversion when no longer needed. The stockpiled material shall be treated so the sediment runoff from the stockpile shall not contaminate surrounding areas or enter the nearby streams. If the Contractor elects not to stockpile and maintain suitable excavated material, other suitable material will be used to backfill the stream diversion at no additional costs to the State. Any excavat ed material that the Engineer deems to be unsatisf actory, will be removed from the project and replaced with suitable material when the stream diversion is backfilled.
247.04 Method of Measurement. Temporary stream diversion will be measured per
each. Stream diversions that are both left and right of a station number will not be measured separately and will be measured as one unit (each). Payment for the disposal and replacement of the unsuitable excavated material during the construction of the stream diversion will be measured and payment made under the appropriate pay items.
247.05 Basis of Payment. Temporary stream diversion, measured as prescribed above,
will be paid per each, which prices shall be full compensation for all excavation, backfill, geotextile fabric, pumps, pipe, sandbags, riprap, silt fence, maintenance of the installation, backfill after no longer needed , and for all labor, tools, equipment, and incidentals necessary to complete the work. Payment will be made under: 247-A: Temporary Stream Diversion - per each SECTION 249 - RIPRAP FOR EROSION CONTROL
249.01 Description . Riprap for erosion control cons ists of furnishing and installing
riprap for the purpose of temporary erosion control by intercepting and slowing the flow of sediment-laden runoff water, or for use as a temporary dam. It also includes the maintenance and removal of riprap when no longer needed. Remove and reset riprap consists of the removal and relocation of riprap to other locations shown on the plans, directed by the Engineer, or indicated on the Contractor’s Erosion Control Plan. Riprap shall be installed in accordance with the specifications in reasonably close conformity with the locations and dimensions shown on the plans or as directed by the Engineer.
249.02 Materials. Stones for riprap shall be Size 100 meeting the requirements of
Subsection 705.04.
249.03 Construction Requirements. Riprap shall be used to construct a berm/dam that
will intercept sediment-laden storm water runoff from disturbed areas, create a retention pond, detain sediment, and release water in sheet flow. The riprap installation shall be maintained in good condition by the Contractor. All necessary work and materials to maintain the integrity of the installation shall be provided until earthwork construction is comple te and permanent erosion-control features are in place. The maintenance of the riprap will not be paid for separately and will be included in the cost for riprap for erosion control. When required, existing riprap may need to be removed and reset at other locations. These locations may be for additional tempor ary erosion control or may be placed in permanent locations design ated by the Engineer.
249.04 Method of Measurement. Riprap for erosion control will be measured per ton.
Remove and reset riprap shall be measured per cubic yard, FM.
249.05 Basis of Payment. Riprap for erosion control, measured as prescribed above,
will be paid for per ton, which prices shall be full compensation for furnishing, installation, maintenance of the installation, and removal/disposal after construction has been completed; and for all labor, tools, equipment and incidentals necessary to complete the work. Remove and reset of riprap, measured as pr escribed above, will be paid for per cubic yard, which prices shall be full compensation for loading, transporting, installing,
