524.14 524.14 Construction Tolerances. For shafts supporting single columns, position the drilled shaft within 3 inches (75 mm) of the plan location in the horizontal plane at the plan elevation for the top of the shaft. For shafts supporting footings, position the center within 6 inches (150 mm) of the plan location. Do not allow the vertical alignment of the shaft to vary from the required alignment by more than 1/4 inch per foot (21 mm/m) of depth. Construct the supported elements at the plan location. Perform all corrections required to construct the supported elements. 524.15 Inspection Records. Provide all necessary equipment and labor needed to obtain measurements for completing the Inspection Records. Obtain measurements before placing concrete. 524.16 Method of Measurement. The Department will measure Drilled Shafts by the number of feet (meters), measured along the axis of the drilled shaft from the required bottom elevation of the shaft to the proposed top plan elevation. The Department will not measure the length of reinforcing steel projecting from the drilled shaft into the pier column or the footing supported on Drilled Shafts as shown on the plans. If the drilled shaft extends into the bedrock, The Department will divide the total length of each drilled shaft into two segments. The length of the lower segment is the length of the bedrock socket, and the length of the upper segment is the length of the drilled shaft above the bedrock socket. If a steel casing extending down to bedrock is used, the Department will measure the bedrock socket from the bottom of the casing to the bottom of the drilled bedrock excavation. If the Engineer is assured that a portion of the metal casing is embedded in solid bedrock, and upon the Engineer’s concurrence, the Department may include the embedded distance as a part of the bedrock socket. 524.17 Basis of Payment. Payment is full compensation for performing required excavation; furnishing and placing steel casings; furnishing and placing reinforcing steel and concrete by free fall, pumping, or tremie method; removing casings; casings left in place; supplying equipment and performing slurry testing; supplying and disposing of slurry; and disposing excess excavated material. The Department will not pay for the cost of performing slurry tests before concreting. The Department will not make separate payment for the trial holes. The Department will not pay for corrections required to construct the supported elements. The Department will pay for accepted quantities at the contract prices as follows: Item Unit Description 524 Foot (Meter) Drilled Shafts, ___" (___ mm) Diameter, above Bedrock 524 Foot (Meter) Drilled Shafts, ___" (___ mm) Diameter, into Bedrock 524 Foot (Meter) Drilled Shafts, ___" (___ mm) Diameter 418

This work consists of constructing reinforced portland cement concrete approach slabs for bridges on the completed and accepted subgrade or subbase. 526.02 Materials. Furnish materials conforming to: Concrete, Class S, HP 3 or HP 4* ................................ 499 Epoxy coated reinforcing steel ................... 509.02, 709.00 Preformed joint filler .............................................. 705.03 Joint sealer .............................................. 705.04 or 705.11 * Use the same class of concrete used in the bridges superstructure that the approach slab is attached to unless otherwise shown in the plans. If the super-structure concrete class for the bridge is not identified in the plans use Class S. 526.03 Forming, Furnishing and Placing Reinforcing Steel. Furnish true and straight steel or wooden side forms. Securely brace and hold forms to the line and grade shown on the plans. Do not allow forms to vary more than 1/8 inch (3 mm) from a 10-foot (3 m) straightedge. Do not remove forms for a minimum of 36 hours. Clean and oil forms after each use. Furnish reinforcing steel and place it in the position shown on the standard construction drawing and firmly secure the steel during placing and setting of the concrete. Tie reinforcing bars at all intersections, except tie reinforcing bars at alternate intersections where bar spacing is less than 1 foot (0.3 m) in any direction. 526.04 Placing and Sampling Concrete. Immediately before placing concrete according to Item 511.10, thoroughly moisten the subgrade or subbase with water in the amount and manner directed by the Engineer. The Engineer will make at least two test cylinders for each 50 cubic yards (35 cubic meters) of concrete. 526.05 Finishing and Curing. If the approach slab is to serve as a base for an asphalt concrete wearing course, finish and texture the approach slab according to Item 305. If the approach slab is to serve as a wearing surface finish and test the surface according to 451.12 and diamond groove the surface according to 511.20. Cure approach slabs according to 511.17.A, deck superstructure concrete. Open approach slabs to traffic according to Table 511.17-1.
