initial driving to determine time effects during the driving of test piles at no additional cost to the Department. I f additional set-checks are determined necessary by the Engineer within two working days following the end of initial driving, each set-check will be paid as an additional set-check. If set-checks are determined necessary by the Engineer after two working days from the end of initial driving, each set-check will be paid for as Pile Redrive. Install instruments on test piles when dynamic load tests are included in the plans or when directed by the Engineer. SUBARTICLE 455-7.2 (Page 543) is deleted and the following substituted: 455-7.2 Manufacture: Fabricate piles in accordance with Section 450. Supply and install EDCs in all square prestressed bridge foundation piles in accordance with Index 20602. Ensure the EDCs are installed by the manufacturer's approved personnel. SUBARTICLE 455-7.8 (Pages 545 and 546) is deleted and the following substituted: 455-7.8 Pre-Planned Splices: Splices shall be made by the doweled splice method contained in the Standard Indexes or may be made using proprietary splices which are listed on the Department's QPL. Splice test piles in the same manner as the production piles. Include in the pile installation plan, the chosen method of splicing and the approximate locations of the splice. Generally, place the splice at approximately the midpoint between the estimated pile tip and the ground surface, considering scour if applicable. Stagger the splice location between adjacent piles by a minimum of 10 feet. Obtain the Engineer's approval prior to constructing any pile sections. Construct piles which are to be spliced using the doweled splice with preformed dowel holes in the bottom section and embedded dowels in the upper section. When electing to use dowel splices, assist the Engineer in performing a dynamic load test on each dowel spliced pile to verify the splicing integrity at the end of driving. Replace any damaged pile splices in accordance with 455-11.2.7. Provide the Engineer 48 hours advance notification prior to driving piles with epoxy-bonded dowel splices. Ensure sections of mechanically spliced piles are restrained from rotating with respect to the other sections. Mechanical pile splices shall be capable of developing the following capacities in the pile section unless shown otherwise in the plans and capable of being installed without damage to the pile, EDC, or splice: a) Compressive strength = (Pile Cross sectional area) x (28 day concrete strength) b) Tensile Strength = (Pile Cross sectional area) x 900 psi Pile Size (inches) 18 20 24 30 36 Bendinll Strenllth (kip-feet) 245 325 600 950 1600
