1 The Engineer may direct that additional testing be performed at a shaft if anomalies or a I 2 soft bottom are detected by the Contractor's testing. If additional testing at a shaft 3 confirms the presence of a defect(s) in the shaft, the testing costs and the delay costs 4 resulting from the additional testing shall be borne by the Contractor in accordance with 5 Section 1-05.6. If the additional testing indicates that the shaft has no defect, the testing 6 costs and the delay costs resulting from the additional testing will be paid by the 7 Contracting Agency in accordance with Section 1-05.6, and, if the shaft construction is 8 on the critical path of the Contractor's schedule, a time extension equal to the delay 9 created by the additional testing will be granted in accordance with Section 1-08.8. 10 11 6-19.3(9)A Schedule of CSL Testing 12 This section, including title, is revised to read: 13 14 6-19.3(9)A TIP Testing Using Thermal Probes or CSL Testing 15 If selected as the nondestructive QA testing method by the Contractor, TIP testing using 16 thermal probes, or CSL testing shall be performed after the shaft concrete has cured at 17 least 96 hours. Additional curing time prior to testing may be required if the shaft 18 concrete contains admixtures, such as set retarding admixture or water-reducing 19 admixture, added in accordance with Section 6-02.3(3). The additional curing time prior 20 to testing required under these circumstances shall not be grounds for additional 21 compensation or extension of time to the Contractor in accordance with Section 1-08.8. 22 23 6-19.3(9)B Inspection of CSL Access Tubes 24 This section's title is revised to read: 25 26 6-19.3(9)B Inspection of Access Tubes 27 28 6-19.3(9)C Engineer's Final Acceptance of Shafts 29 This section, including title, is revised to read: 30 31 6-19.3(9)C TIP Testing With Thermal Wires and TAPs 32 If selected as the nondestructive QA testing method by the Contractor, TIP testing with 33 thermal wires and TAPs (See Section 6-19.3(6)E) shall be performed. The TIP testing 34 shall commence at the beginning of the concrete placement operation, recording 35 temperature readings at 15-minute intervals until the peak temperature is captured in 36 the data. Additional curing time may be required if the shaft concrete contains 37 admixtures, such as set retarding admixture or water-reducing admixture, added in 38 accordance with Section 6-02.3(3). The additional curing time required under these 39 circumstances shall not be grounds for additional compensation or extension of time to 40 the Contractor in accordance with Section 1-08.8. 41 42 TIP testing shall be conducted at all shafts in which thermal wires and TAPs have been 43 installed for thermal wire analysis (Section 6-19.3(6)A). 44 45 6-19.3(9)D Requirements to Continue Shaft Excavation Prior to Acceptance of 46 First Shaft 47 This section, including title, is revised to read: 48 49 6-19.3(9)D Nondestructive QA Testing Results Submittal 50 The Contractor shall submit the results and analysis of the nondestructive QA testing for 51 each shaft tested. The Contractor shall submit the test results within three working days 52 of testing. Results shall be a Type 1 Working Drawing presented in a written report.
