Section 247 Section 247 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, maintenance of the new installation, and removal/disposal after construction has been completed; and for all labor, tools, equipment and incidentals necessary to complete the work. Payment will be made under: 249-A: Riprap for Erosion Control - per ton 249-B: Remove and Reset Riprap - per cubic yard
Division 300 — Division 300
Division 300 — Bases
The sections in the 300 series include the spec ification requirements for bases, shoulders, and other work closely related to the construction of the pavement foundation and shoulders. The term "course" used in this series of sections shall be understood to mean a structural component of specified thickness. A course may consist of one or more layers. Shoulder courses shown on the plans to be constructed separately from base courses shall be performed in accordance with the provisions and requirements of Section 320. SECTION 304 - GRANULAR COURSES
304.01 Description . This work consists of furnishing granular materials and the
construction of one or more courses of base, shoulders, or other required construction on a prepared foundation in reasonably close conf ormity with the lines, grades, and typical cross sections shown on the plans or established by the Engineer.
304.02 Materials .
304.02.1 General . Unless otherwise specified, materials used in this work shall
conform to the requirements of Subsecti ons 703.04 & 703.07. General conditions governing the use of materials shall be as set out in Section l06. Crushed concrete meeting the requirements of Subsection 703.04.3 may be used in lieu of granular courses or crushed stone courses specified in the contract. This applies to base courses, shoulders, or other required construction on a prepared foundation. When crushed stone base is bid as alternate pay items, the Contractor must select one of the alternates at the time of bid. The Contra ctor must use the selected crushed stone base throughout the entire project.
304.02.2 Sampling, Te sting and Acceptance . A minimum of one random sample will
be obtained from the roadway for each 1000 cubic yards or 1400 tons for determining acceptance of the material for gradation, liquid limit and plasticity index. When borderline or failing results are obtained the Engineer may increase the sampling frequency. When a roadway sample fails to meet the re quirements of the specifications additional samples will be taken along the roadway for determining the limits of the inferior material. Such inferior material shall be corrected or removed and replaced at no additional costs to the State.
304.03 Construction Requirements.
304.03.1 Equipment . When measurement for payment is to be made by the ton, the
Contractor shall furnish approved platform s cales capable of weighing the entire loaded vehicle. Scales and their use shall be in accordance with the requirements set out in Subsection 40l.03.2.1.11, except they shall be installed at an approved location on or near
