Muck excavation as described in Subarticle 210.03(b) will require the use of the following modified cross section and average end area method. The volume will be measured between theoretical vertical side slopes, a station or substation at a time, immediately after completion of muck excavation and before backfill is placed. No measurement or allowance will be made for necessary excavation of material for sloughing, subsidence, flattening sides, slumps, or rehandling materials or for shaping and dressing disposal areas. The sloughing, subsidence, flattening, or slump of side slopes in muck will not be classed as slides.
b.Measurement Limitations. Measurement of pay quantities will not include any excavated material used for purposes other than those designated except as provided under Article 106.08. Where material has been excavated beyond the designated slope line and wasted, the unauthorized wasted material will be measured and deducted from the excavation quantities. Any material excavated prior to the staking out and cross sectioning of the borrow sources by the Engineer, or in excess of that ordered for the work, will not be included in the quantity measured for payment. If the Contractor places more borrow than is necessary, thereby causing a waste of excavation, the amount of such waste will be deducted from the borrow excavation as measured in the borrow source. When a borrow area is adjacent to the right of way, the dividing line between unclassified excavation and borrow excavation shall be either a vertical plane through the right of way line or the proposed backslope as shown on the plans, whichever is most economically advantageous to the State.
210.10 Basis of Payment.
a.Unit Price Coverage.
1.Roadway and Drainage Excavation. The accepted volume of Unclassified Excavation - Item No. 210-A, Channel Excavation - Item 210-B, and Muck Excavation - Item No. 210-C, when provided in the plans or proposal, measured as provided above, will be paid for at the contract unit prices bid for these items which shall be payment in full for: excavation; disposal of surplus and unsuitable materials (see Articles 210.04 and 210.05); hauling; formation and compaction of embankment; preparation and completion of subgrade and shoulders except when this work is included in other pay items; the completion of all cuts, embankments, and channel excavation to conform to the lines, grades, and cross section indicated on the plans or otherwise directed; and the completion of the roadway together with its appurtenances of intersecting roads, streets, driveways, approaches, temporary drainage facilities, and other related incidental work for which the proposal contains no contract unit prices. The said contract unit prices for the excavation item shall be payment in full for all equipment, tools, labor, and incidentals necessary to complete the work. If no contract items for Channel Excavation and/or Muck Excavation are provided, such work will be paid for as Unclassified Excavation. Exceptions to the above will be made in the event of the following:
a.If a backslope already completed and dressed is destroyed by a slide, or if the Engineer orders additional material taken from a completed and dressed backslope, any redressing required will be paid for as provided in Article 104.03.
b.If a slide occurs after completion of the subgrade to line and grade or during subsequent work in the immediate area and is of such nature and extent that the Engineer, in order to avoid damage to the previous work, directs its removal, and such requires equipment other than equipment normal to the project, an adjustment in price may be made. However, in no case shall such an increase exceed 25 percent of the unclassified excavation contract unit price.
c.If no item for Muck Excavation is provided in the plans or proposal, such excavation will be classified as Unclassified Excavation and payment will be made at two times the unit bid price for Unclassified Excavation.
2.Borrow Excavation. The accepted volume of Borrow material designated under Items 210-D, 210-E and 210-F, measured as noted above, will be paid for at the contract unit price bid for the items, which shall be payment in full for the royalty and other expenses incidental to procurement, construction and maintenance of haul roads, clearing and grubbing, stripping, excavating, loading, hauling, source moves, dumping, spreading, and also for formation and compaction of embankment, trimming slopes, disposing of surplus materials, preparation and completion of subgrade, shoulders, and SECTION 212 MACHINE GRADING SHOULDERS intersecting roadways and furnishing of all equipment, labor and incidentals necessary to complete the work. This pay item also includes any necessary work as may be required by the Engineer or owner in the final dressing of the pit, including grassing or other landscape work.
b.Blank.
c.Payment will be made under Item No.: 210-A Unclassified Excavation - per cubic yard {cubic meter} 210-B Channel Excavation - per cubic yard {cubic meter} 210-C Muck Excavation - per cubic yard {cubic meter} 210-D Borrow Excavation - per cubic yard {cubic meter} 210-E Borrow Excavation(Underwater * ) - per cubic yard {cubic meter} 210-F Borrow Excavation(Underwater * ) - per ton {metric ton} * Specify either Backfill or Embankment. SECTION 212 MACHINE GRADING SHOULDERS
212.01 Description.
This Section shall cover the work of reconstructing the shoulder of a roadway where the grading is of such character that the material can be moved, mixed, and shaped with a motor patrol of adequate power and weight {mass}. In general, this work shall consist of clipping the shoulder, where directed, prior to resurfacing and blading the shoulder after the resurfacing has been completed. Any additional material needed to bring the shoulder to the desired profile will be classified and paid for under the appropriate section for the type of material furnished. If seeding or other items are needed for erosion control, such items will be shown on the plans and paid for under the appropriate specification section. Unless otherwise noted by plan details, the completed work shall conform to the shoulder requirements for lines, grades, and typical section indicated by the plans or established by the Engineer.
212.02 Material.
Material used under this Section shall be of the quality and character noted on the plans or ordered by the Engineer, suitable for the purpose intended and consistent with the requirements for such material noted in other parts of this specification.
212.03 Construction Requirements.
a.General. Clipping, or blading, of grass and soil from the shoulder, as provided by the plans or directed, shall be completed in advance of resurfacing operations. The removed material shall be windrowed a sufficient distance and in such a manner as not to pose a safety hazard to the motoring public. Where directed, the entire width of the shoulder shall be plowed, scarified or otherwise loosened. The shoulder then shall be re-formed by blading the material from the windrows, or by the addition of extra material as specified or directed, with the machine grader and compacting it to the satisfaction of the Engineer. Watering shall be used, as necessary, to aid compaction. The machine grading shall continue until the shoulder is completed to conform to the lines, grades, and typical section shown on the plans or directed.
b.Equipment. The Contractor shall provide appropriately sized equipment in sufficient numbers to perform the work within the guidelines noted herein and the time frame for the contract.
c.Additional Material. It will be considered practicable to move material up to 100 feet {30 m} longitudinally by means of the machine grader and all material moved within that limit will be paid for in the contract price for machine grading shoulders. When it is necessary to waste surplus material, such material shall be wasted on the front slope of the roadway in the vicinity of the removal site, to the satisfaction of the Engineer. Material secured from sources outside the right-of- way will be classified under the applicable classification.
