Vl 4,4'M1 roundness survey and capping shall all be completed in the period of one work shift. n B. At all times during the progress of the construction, the Contractor shall protect the wells in such a manner that effectively prevents tampering with the well and/or the entrance of foreign matter into the well. Upon completion of the well project, the Contractor shall weld a %-inch steel plate on the end of each casing to the finished elevation shown on the Drawings. �F 1. MEASUREMENT AND PAYMENT: Full compensation for conforming to g these requirements, including all the labor, materials, tools, equipment, incidentals, and for doing all the work involved in final disinfection and i capping, as specified in the Standard Specifications, these special provisions, and as directed by the Engineer, shall be considered as included in the prices paid for the various contract items of work involved and no additional compensation will be allowed. ✓ 3.16 TESTING FOR PLUMBNESS AND ALIGNMENT A. General: The drilled and cased wells shall be tested for alignment prior to acceptance. The Contractor may also make additional tests as the well and casing are being constructed if he determines it will aid in his control of the work. The Contractor shall furnish all labor, tools and equipment and shall make the tests in accordance with the provisions of AWWA Standard A100, Section 5.1 and 5.2 to the satisfaction of the Engineer. The well shall conform to tolerances indicated in AWWA Standard A100., paragraph 4.7.9. j B. Drift Indicator (Plumbness) Survey: A mechanical drift indicator shall be run in the completed well pilot hole for the Production Well and the completed well bore for the Nested Monitoring Well and the drift determined at intervals of 50 feet of depth throughout the total depth of the hole. If a deflection of P1 less than one degree is indicated, the well shall be deemed in proper plumbness and alignment. if any reading taken indicates a deflection from vertical exceeding one degree, the Contractor shall immediately notify the ��rtgineer. The mechanical drift indicator surveys shall be analyzed'by the Contractor and the Engineer. If, in the opinion of the Engineer, the alignment is not acceptable, the Contractor will be required to correct the alignment of ' the well, or abandon the well and drill another well at his expense. The . ` Contractor may perform an alignment survey on the drilled, uncased hole at }' his expense. C. Roundness Survey: A survey shall be performed on the completed wells to �~ determine the roundness. Roundness shall be proven by passing a 40-foot- } long dummy through the entire length of the well. The dummy that is used j shall consist of a rigid spindle with a minimum of three truly cylindrical rings, R' each ring being a minimum of 12 inches wide. The rings shall be located one at each end and one in the center. Division III-32 4
