When not otherwise specified, sealants or membranes shall remain in place. If removal is by milling, work shall be done in accordance with the requirements of Section 210 . Removal methods shall be subject to the approval of the Engineer and shall be such as to prevent any damage to the remaining surface. Any necessary deck repair will be paid for as shown on the Plans, except damage caused by Contractor’s negligence shall be repaired at the Contractor’s expense. 529.0 4 REMOVA L OF STRUCTURES . The Contractor shall dismantle the structure and shall remove the dismantled members or materials. Removal of structures spanning bodies of water will be conducted so as to avoid dropping materials into the water. The entire site of the old structure shall be restored to a condition satisfactory to the Engineer. The existing concrete or masonry shall be removed by drilling, chipping, or other methods approved by the Engineer. All cut surfaces, unless otherwise specified, shall be on a reasonably vertical or horizontal plane with sharp straight corners. Existing re inforcing steel to be retained shall be carefully preserved and cleaned for use in the new construction. Existing reinforcing steel damaged beyond reuse as determined by the Engineer shall be replaced by splicing a bar of equal diameter to the damaged bar in a manner approved by the Engineer at no additional compensation to the Contractor. Holes for expansion bolts or dowels shall be drilled in the retained concrete at the locations shown on the Plan s. When the material from the structure is to be retained by the Agency or others, or is to be reused in the construction, it shall be carefully dismantled by the Contractor and all adhering concrete removed. Materials to be retained or reused shall be stored at the location specified in the Contract or as direct ed by the Engineer. 5-240 When the existing superstructure steel is to be retained for future use, the Contractor shall take every precaution necessary to prevent damage to the existing steel. Damage to the existing steel caused by the Contractor’s operations shall be repaired by the Contractor to the satisfaction of the Engineer at no additional cost to the Agency. Where portions of existing structures are to be removed, the portions indicated shall be removed t o the lines shown on the Plan s, or as directed by the Engineer, in such a manner as to leave the remainder of the structure undamaged and in proper condition for the intended use. Any damage to the portions remaining in service shall be satisfactorily repa ired by the Contractor at no additional cost to the Agency. Explosives will not be permitted for partial removal of any structure. Removed parts of the existing structure that are to be reused in the new construction shall be safeguarded, cleaned, or other wise prepared as shown on the Plan s or in the Contract and incorporated into the work as shown on the Plan s or as directed by the Engineer. 529.0 5 METHO D OF MEASUREMENT . The quantity of Removal of Bridge Pavement to be measured for payment will be the number of square yards of bridge deck from which bituminous pavements , sealants, and membranes have been removed as shown on the Plan s or ordered by the Engineer. The quantity of other items to be measured for payment will be as follows:
a.Removal of Str ucture will be on a unit basis for each removal at the locations shown on the Plan s.
b.Partial Removal of Structure will be on a unit basis for removal of the materials between the limits shown on the Plan s.
c.Removal of Concrete or Masonry will be the number of cubic yards or square yards of concrete or masonry measured in place and removed between the limits shown on the Plan s or as ordered by the Engineer. 529.0 6 BASIS OF PAYMENT . The accepted quantity of Removal of Bridge Pavement will be paid for at the Contract unit price per square yard. The accepted quantity of Removal of Structure and of Partial Removal of Structure will be paid fo r at the Contract unit price per each. The accepted quantity of Removal of Concrete or Masonry will be paid for at the Contract unit price per cubic yard or square yard. Payment will be full compensation for the removal and disposal of the specified items; for removal, salvage, and stockpiling of components and materials specified in the Contract; for excavating, backfi lling, regrading, and performing site restoration incidental to the removal of specified items; and for furnishing all labor, tools, equipment, and incidentals necessary to complete the work. 5-241 Removal of Bridge Pavement, when not included as a separate pay item , will not be paid for directly, but will be considered incidental to either Removal of Structure or Partial Removal of Structure as specified in the Plan s. Payment will be made under: Pay Item Pay Unit
