613Adjustment of Castings, Gratings, and Utility Appurtenances

612.02.2 Acceptance of Mixture. The acceptance of the mixture at the job site will be

based on the performance of the flowable fill mixture placed and will be at the discretion of the Engineer. For acceptance of the mixture at the job site, the mixture shall be self- leveling and shall not settle, segregate, or have excessive bleed water.

612.02.3 Manufacturing. Flowable fill will be batched, mixed, and transported in

accordance with the requirem ents of Section 804.

612.02.4 Sampling and Testing . The yield shall be determined by testing the first load

placed on each production day in accordance with AASHTO T121. If adjustments are made to the mixture design proportions to correct for yield, the yield shall be determined on the next load with the adjusted proportions.

612.03 Construction Requirements. Prior to placing flowable fill, each end of the

structure shall be plugged leaving an opening at each end no larger than necessary to accommodate the filling equipment. Flowable fill shall be discharged from the mixer by any reasonable means into the area to be filled. Unless otherwise approved by the Engineer, filling will begin on the downstream end of the structure and continue until no further material will enter the structure. The flowable fill will then be continued from the upstream end of the structure.

612.04 Method of Measurement. Flowable fill will be measured by the cubic yard,

which will be determined from the yield in a ccordance with the requirements of Subsection

612.02.4 The yield will be calculated by dividing the actual batch weights of each load by the unit weight of the mix, which will be determined by testing the first load placed on

each production day.

612.05 Basis of Payment. Flowable fill, measured as pr escribed above, will be paid for

at the contract unit price per cubic yard, which price shall be full compensation for furnishing all labor, equipment, tools and materials to complete the work. Payment will be made under: 612-A: Flowable Fill, Excavatable - per cubic yard 612-B: Flowable Fill, Non-Excavatable - per cubic yard SECTION 613 - ADJUSTMENT OF CASTINGS, GRATINGS, AND UTILITY APPURTENANCES

613.01 Description . This work consists of furnishing all materials and adjusting existing

catch basins, inlets, manholes and other designated structures in accordance with these specifications and in reasonably close conformity with the lines, grades and dimensions shown on the plans or as established.

613.02 Materials . New materials used in this construction, unless otherwise stipulated,

shall conform to the requirements set out in Section 604.

613.03 Construction Requirements .

613.03.1 General . Construction requirements shall be, insofar as applicable, as described

in Section 604. Castings, gratings, frames, covers, and other metal units shall be cleaned before resetting. Where a casting, grating, or utility appurtenance is to be lowered, the masonry shall be removed to sufficient depth so that a set of proper dimensions may be reconstructed to receive the casting, grating or utility appurtenance at the ne w grade. Where the castings, grating or utility appurtenance is to be raised less than one foot, a new ring of masonry may be added without disturbing the old masonry. The use of metal rings to raise appurtenances will be allowed with approval of the Engineer . Where the distance to be raised exceeds one foot, the old masonry shall be removed to sufficient depth, as directed, to permit a neat and workmanlike extension to the new grade. The Contractor shall replace, at no additional co st to the State, all units or parts indicated to be salvaged and reused that are damaged as a result of the Contractor’s operation.

613.03.2 Cleaning Up . Upon completion of the adjustment, all surplus material shall be

removed, and the structure and site of the work shall be left in a neat and clean condition. The entire structure shall be thoroughly cleaned of accumulations of silt, debris, or foreign matter of any kind and shall be kept clean until the final inspection.

613.04 Me thod of Measurement . Adjustment of castings, gratings, utility

appurtenances, etc. for which pay items are incl uded in the contract will be measured on a lump sum basis or by the num ber of units, as specified.

613.05 Basis of Payment . Adjustment of castings, gratings, and utility appurtenances for

which pay items are included in the contract w ill be paid for at the contract lump sum price or at the contract unit price per each, as indicated, which shall be full compensation for completing the work. Payment will be made under: 613-A: Adjustment of Castings, Gratings and Utility Appurtenances - lump sum 613-B: Adjustment of Castings - per each 613-C: Adjustment of Gratings - per each 613-D: Adjustment of Descri ption - lump sum or per each SECTION 614 - CONCRETE DRIVEWAYS
