Section 2406. Concrete Structures.
The provisions of this section shall apply to all types of bridge structures in which the main members spanning the various supports are composed of concrete. The concrete superstructure shall be placed on a substructure constructed according to Section 2405. The various types of structures shall be built in conformance with the contract documents. In addition to this section, the provisions of Sections 2403, 2404, 2405, 2407, 2412, 2413, and 2414 shall apply.
FALSEWORK AND FORMS.
Construction of falsework and forms shall conform to Article 2403.17 and Article 2403.07, E. The Contractor shall notify the Engineer at least 24 hours before placing any concrete in the superstructure of a concrete bridge so the Engineer may inspect the falsework and forms for conformance with falsework plans, alignment, and general fitness. Concrete shall not be placed until the falsework and forms have been inspected by the Engineer. Falsework and forms shall provide for the full camber and roadway crown specified in the contract documents. Forms shall be removed according to Article 2403.18.
Concrete shall be placed as provided in Section 2403 and the following:
A. Placing Concrete in Slab Superstructures.
Concrete for each span shall be placed to its full depth in one continuous operation and without joints except as provided in the contract documents. The Contractor will be required to provide adequate material, labor, and equipment to assure that the concrete required to be completed in a single, continuous operation can be placed in 10 hours.
B. Placing Concrete in Deck Girder Superstructures.
Unless otherwise provided in the contract documents, concrete for each girder shall be placed continuously for the entire length of the girder in level, horizontal layers. Concrete for the floor shall be placed to the required thickness in a single placement. The floor shall be placed as quickly as possible after completion of its supporting girders and shall be completed within the same working day as the girders.
Joints shall be constructed in the locations shown in the contract documents and in the manner specified in Article 2403.13.
Floor drains shall be constructed and placed at the locations shown in the contract documents. Drains behind abutments, wingwalls, and similar structures shall be installed as specified in Section 2502.
Concrete superstructures shall be finished in accordance with the provisions of Article 2403.21. Concrete floors shall be finished in accordance with the provisions of Section 2412.
METHOD OF MEASUREMENT AND BASIS OF PAYMENT.
For the quantities involved in concrete structures, the quantities will be measured and the Contractor will be paid as provided in the following sections:
These payments shall be full compensation for furnishing all materials, equipment, and labor and for performance of all work necessary to complete the concrete structure in conformance with the contract documents.
Deduction will not be made for the volume of concrete displaced by floor drains, expansion joints, or metal strips for sealing joints. The cost of all bituminous expansion joint material, metal strips for sealing joints, and other small miscellaneous items shall be included in the price per cubic yard (cubic meter) for structural concrete. The weight (mass) of structural steel paid for will include all steel expansion plates, castings of steel or iron, or welded shapes for floor drains, bearing plates, anchor bolts, fasteners, and other steel parts except steel reinforcement for concrete.
