8−111a. General. Repairs accomplished by the form and cast-in-place method shall be performed in accordance with the applicable requirements of Section 808, CAST-IN-PLACE STRUCTURE CONCRETE MASONRY of these specifications.
b.Bonding to Existing Surfaces. Prior to placing the Cast-in-Place Concrete, surfaces shall be prepped in accordance with these specifications or as indicated on the Plans.
c.Use of Self Consolidating Concrete (SCC) in Form and Cast-in-Place Concrete. SCC concrete may be used for form and cast-in-place concrete repairs or as indicated on the plans. Concreting procedures shall be performed by pers onnel experienced with the placement of SCC mixes. All repair areas shall be adequately formed to contain the proposed SCC material, and all resulting holes from the required formwork fasteners shall be properly filled with an approved cementitious material. Special care shall be taken so that the form is properly sealed against leaks, since SCC is more fluid than standard mixes. If excessive surface voids are observed when stripping a form, further placements of the SCC shall cease until the mix and/or placement problem is identified and corrected to the satisfaction of the Engineer.
d.Final Finish. All exposed surfaces shall be finished straight and true, approximating the original contour as close as practicable. The final finish shall be as indicated on the plans.
817.04 METHOD OF MEASUREMENT. "Repairs to Structure Concrete Masonry - Pneumatically
Applied Mortar", "Repairs to Structure Concrete Masonry - Patching Mortar" and "Repairs to Structure Concrete Masonry - Form and Cast-in-Place Concrete" will be measured by either the number of “Square Feet” or “Cubic Feet” of new concrete actually placed in accordance with the Contract Documents and/or as directed by the Engineer.
817.05 BASIS OF PAYMENT . The accepted quantities of "Repairs to Structure Concrete
Masonry - Pneumatically Applied Mortar", "Repai rs to Structure Concrete Masonry - Patching Mortar" and "Repairs to Structure Concrete Masonry - Form and Cast-in-Place Concrete" will be paid for at the respective contract unit prices per “Square Feet” or “Cubic Feet” as designated in the Proposal. The price so stated shall constitute full and complete compensation for all labor, materials, equipment, and all incidentals required to finish the work, comple te in place and accepted by the Engineer. Steel reinforcing bars and wire mesh reinforcement will be paid for separately by Force Account in accordance with the provisions of Subsection 109.04 of these specifications, or when applicable will be paid under the respective pay item for Reinforcing Steel Section 810 . SECTION 818 PORTLAND CEMENT CONCRETE BRIDGE DECK REPAIR
818.01 DESCRIPTION. This work consists of removing deteriorated concrete from bridge deck
surfaces, erecting form-work and the placement of new Portland cement concrete, all as indicated on the contract drawings and in accordance with these Specifications.
