is required and borrow is not specified as a pay item, payment will be made in accordance with 203.28.
If a waste area is required and the contract documents do not identify excess excavation or require removal of any items, payment will be made in accordance with
203.28. Except for sign foundations, traffic signal foundations, and highway illumination
foundations, if a type of excavation for which no pay item exists is required and the new type of excavation requires the Contractor to use equipment not otherwise being 330 used on the contract, payment will be in accordance with 203.28. If a type of excavation for which no pay item exists is required and the new type of excavation requires additional traffic control not shown on the plans or results in traffic control being required for an additional period of time, payment will be made in accordance with 203.28.

Cofferdam .................................................................................. LS Excavation, Dry ......................................................................... CYS Excavation, Foundation, Unclassified ....................................... CYS Excavation, Wet ........................................................................ CYS Excavation, X ............................................................................ CYS The cost of placing and compacting of all backfill when the materials used are obtained from excavation, clearing and grubbing required and not paid for under another pay item, formation of embankments made with material from structure 350 excavation, and disposal of all surplus or unsuitable excavation, unless otherwise specified shall be included in the cost of the pay items. The cost for disposing of surplus or unsuitable excavated materials outside the right-of-way shall be included in the various pay items in this section. (a) Culverts This requirement will not include pipe culverts. Excavation for culverts will not be paid for directly. The cost thereof shall be included in the cost of the structure or structure extension. The cost of all necessa ry removal and satisfactory disposal of all 360 or part of the existing old structure unless its removal is otherwise provided for, cleaning out an old channel or constructing a new channel within the right-of-way limits and widening it to the grade of the existing or proposed new stream bed as shown on the plans or as directed, construction of all necessary curbs and cofferdams and their subsequent removal, subsoil borings or soundings below bottom of footings, 206.11 223 dewatering, shoring, disposal of excavated materials, and all labor, equipment, tools, and necessary incidentals shall be included in the cost of this work.
If a culvert is lowered or relocated at th e direction of the Engineer, or material of such nature is encountered so that additional excavation is necessary, the additional 370 excavation will not be paid for if it is 10 cu yds or less. Additional excavation in excess of 10 cu yds will be paid for at $125.00 per cu yd. If the additional excavation in excess of 10 cu yds is identified as class X excav ation, and there is no pay item for class X excavation, the additional work will be paid for at $125.00 per cu yd for the quantity in excess of 10 cu yds, regardless of the depth the culvert is lowered.
The cost of clearing right-of-way within the project limits, constructing, dewatering, and removal of cofferdams, if not a pay item, subsoil borings or soundings below bottoms of footings, final prepar ation of foundation surfaces, disposal of 380 excavated material, shoring, and all labor, equipment, tools, and incidentals necessary to the satisfactory completion of the excavation shall be included in the cost of this work. The cost of all required working drawings; furnishing, hauling, and placing necessary materials; construction; maintenance; dewatering; shoring, removal of bracing; removal of or cutting off the sheeting; and labor, equipment, tools, and necessary incidentals shall be incl uded in the cost of cofferdams. If cofferdams are not specified as a pay item, and if cofferdams are necessary, 390 their cost shall be included in the cost of ex cavation or the concrete requiring their use. If there is no pay item for dry excavation, the cost of this part of the work shall be included in the cost of the foundation concrete or for other concrete requiring such excavation. However, where waterway excavation, common excavation, or other classified excavation overlaps the area of dry foundation excavation, no deduction will be made in the pay volume of such overlapping classified material. This exception will apply only if dry excavation is not a pay item. Except as otherwise provided in 206.05, the cost of foundation excavation 400 unclassified shall include all work and elements of volume, and excavation described above for wet excavation and dry excavation, regardless of whether or not water is encountered. The cost of foundation excavation unclassified shall not include the cost of class X excavation. The classifications for necessary excavation for a cantilevered wing outside the limits of foundation excavation shall be the same as those governing the excavation inside such limits. The quantity to be paid for will be that actually removed from its original position within vertical planes 18 in. outside the neat lines shown on the plans and parallel thereto and above a plane 1 ft below and parallel to the bottom surface of 410 the wing. 206.11 224 The classifications for necessary excavation for arch superstructures outside the limits of foundation excavation or waterway excavation shall be those governing the excavation inside the limits of foundation excavation or waterway excavation, depending on the location of the excavation for the arch superstructure. Such excavation shall be bounded by vertical planes which are 1 ft outside the outside faces of the arch ring and parallel thereto, by a vertical plane passing through the intersection of the intrados of the arch ring and the or iginal ground line and parallel to the face of the abutment, and the vertical plane bounding the foundation excavation on the side 420 adjacent to the arch ring. Th e lower limit shall be a sloping plane which is 1 ft below a plane connecting the intersection of the intrados of the arch ring and the original ground, and the intersection of the intrados of the arch ring with the vertical plane bounding the foundation excavation. For U-abutments, the limits of dry excavation to be paid for will be extended to include all material removed from between the limits of the wing excavation and above the elevation of the bottom of the lowest tie beam. If the bottom of the lowest tie beam is below the upper limits of wet excavation, the limits of wet excavation and dry excavation to be paid for will be extended to include material actually and necessarily 430 removed from between the limits of the wing excavation.
Where it is necessary to excavate outside the foundation excavation limits for superstructure or extensions other than those described above, the pay limits will be extended to include all such excavation, as determined necessary. If a suitable sump is constructed outside the pay limits as described above, such limits will be extended to include the actual lines of the sump. The additional pay limits added for the sump will not exceed 4% of the area of the footing involved. 440
in accordance with 206.02(a)1, shall be include d in the cost of the foundation material.
