837.04 METHOD OF MEASUREMENT . “Repairs to Structural Concrete Masonry with Integrally
Colored Concrete or Patching Mortar” will be measured by the number of cubic feet of such materials actually placed in accordance with the Plans and/or as directed by the Engineer. 837.05 BASIS OF PAYMENT . The accepted quantity of “Repairs to Structural Concrete Masonry with Integrally Colored Concrete or Patching Mortar” will be paid for at the contract unit price per cubic foot as listed in the Proposal. The price so-stated shall constitute full and complete compensation for all materials, labor, equipment, tools, forms, scaffolds, wire mesh, anchors and bonding grout, and all incidentals required to finish the work, complete and accepted by the Engineer. Steel reinforcement and dowels shall be paid for under separate items. SECTION 838 SAW CUT IN EXISTING CONCRETE WALLS
838.01 DESCRIPTION . This work consists of saw cutting existing reinforced concrete retaining
walls and/or wingwalls at the locations indicated on the Plans or as directed by the Engineer, all in accordance with these Specifications. 838.02 MATERIALS . Not applicable.
838.03 CONSTRUCTION METHODS . Two separate horizontal sa w cuts, to the limits and depths
as shown on the Plans, are required to be made along each wall face to reduce and control the amount of concrete breakage required and to assure a neat line in the finished work. Copings may be cut transversely into smaller pieces or removed in one piece at the option of the Contractor, as long as the concrete to remain is not damaged during the removal operations. The intentions of the saw cut is to cut existing reinforcements at the saw cut lines. Suitable guidelines and devices must be used to assure cutting along a true line, as shown on the Plans. The type of concrete saw and the method of support to be used will be subject to approval by the Engineer. 838.04 METHOD OF MEASUREMENT . “Saw Cut in Existing Conc rete Walls” will be measured by the number of linear feet actually cut in accordance with the Plans and/or as directed by the Engineer. 838.05 BASIS OF PAYMENT . The accepted quantity of “Saw Cu t in Existing Walls” will be paid for at the contract unit price per linear foot as listed in the Proposal. The price so-stated constitutes full and complete compensation for all labor, materials, and equipment, and all incidentals required to finish the work, complete and accepted by the Engineer. 8−188 No payment will be made for any transverse saw cuts in walls made in order to divide it into practical lengths for removal. SECTION 839 REMOVE AND DISPOSE BITUMINOUS CONCRETE PAVEMENT FROM CONCRETE BRIDGE DECKS - PARTIAL-DEPTH AND FULL-DEPTH
839.01 Description.
839.01.1 Partial-Depth Removal. This work consists of the removal and disposal of a portion of the existing bituminous pavement overlay from the concrete bridge deck within the limits indicated
on the Plans or as directed by the Engineer, all in accordance with these Specifications. 839.01.2 Full-Depth Removal . This work shall consist of the complete removal and disposal of the existing bituminous pavement overlay, including the waterproofing membrane, from the concrete bridge deck within the limits indicated on the Plans or as directed by the Engineer, all in accordance with these Specifications. 839.02 MATERIALS. Not applicable.
839.03 Construction Methods .
839.03.1 Partial-Depth Removal . The Contractor shall ensure that the process of partial pavement
removal will not cause any damage to the waterproofing membrane, underlying concrete deck and/or bridge joints to remain. The Contractor shall also ensure that the method proposed will remove the specified layer thickness of the bituminous wearing surface as indicated on the Plans. Under no circumstances will full depth removal be allowed. The specifications, including gross weight(s) of the proposed equipment and/or machinery to be used for the removal operation shall be submitted to the Engineer for approval a minimum of 14 calendar days prior to the start of work; the Engineer will respond to the Contractor within 7 calendar days of receipt of the Contractor’s submission. The proposed equipment and/or machinery loads shall not exceed the legal load limit or the posted load limit for the bridge, whichever is less. In addition, equipment and/or machinery to be used shall have the capability and precision nece ssary to adhere to the pavement removal depth requirements. Damage caused to the waterproofi ng membrane, bridge deck and/or bridge joints as a result of the Contractor’s operation shall be repaired to the satisfaction of the Engineer at no additional cost to the State. The pavement removal shall be performed in a ccordance with the sequence of construction and traffic controls indicated on the Plans. Where required, the Contractor shall saw cut the pavement to prevent over-breakage into the vehicular travel areas. In the event that this type of over-breakage does occur, the Contractor shall immediately patch the damaged bituminous areas using a bituminous patching material which conforms with SECTION 410, TEMPORARY
