The work covered by this section consists of the construction of footings for ground-mounted Type A and Type B signs in accordance with the requirements of the plans and the provisions of these specifications. The footings shall be either reinforced or plain Class A concrete footings as shown in the plans.
The provisions of Section 900 will be applicable to all work covered by this section.
All materials shall meet the requirements of Division 10 shown below:
Class A concrete Section 1000
Steel bar reinforcement Section 1070
Anchor bolts Article 1072-6
Joint sealer Article 1028-2
The Engineer will establish the location of each sign longitudinally. The Contractor shall be responsible for the proper offset locations for the footings.
The Contractor shall perform all excavation necessary for footing construction to the elevations and dimensions shown in the plans, or as directed by the Engineer. The sides of the excavation shall conform as nearly as possible to the required dimensions. Concrete shall be placed against undisturbed soil, unless otherwise permitted by the Engineer.
Concrete sign footings shall be constructed in accordance with Section 825. The tops of the footings shall be shaped to conform with finished ground elevations such that water will not collect against the supports. No construction joints will be permitted.
The top 6 inches of footings shall be formed by methods approved by the Engineer. Supports shall be centered in the footings, securely braced, and held in proper position and alignment during placement of the concrete. Concrete shall be given an ordinary surface finish.
All backfill shall be thoroughly compacted in 6 inch layers. The Contractor shall remove all excavated material that is not needed from the site.
The quantity of concrete sign footings to be paid for will be the number of cubic yards of concrete which has been incorporated into the completed and accepted footing. The number of cubic yards of concrete will be computed from the dimensions shown in the plans or from revised dimensions authorized by the Engineer, calculated to the nearest 0.01 of a cubic yard.
The quantities of concrete sign footings, measured as provided in Article 9024, will be paid for at the contract unit price per cubic yard for "Reinforced Concrete Sign Footings" and "Plain Concrete Sign Footings".
Such prices and payments will be full compensation for all work covered by this section including but not limited to staking out the footings, excavating for the footings in any material including rock that may be encountered, constructing and removing forms, furnishing and installing reinforcing steel, and furnishing and placing concrete.
