Mr. Bob Egleston 6ugust.2, 2018 Page 2 Structure Comment 14b. The following should be addressed: MKA Response MAGNUSSON KLEMENCIC ASSOCIATES The design of the piles appears to be a i. "Deferred Structural Submittals" section deferred submittal. The piles should be of the general notes on Sheet S-003 of listed on Sheet 5-003 in the "Deferred the drawings submitted with the original Structural Submittals" section. comment responses included micropiles as a deferred structural submittal ii. The pile design loads appear to exceed the values specified in Table 7/S-401. The tabulated values and the calculated loads both appear to be ASD values. See calculation pages 1047-1048 and 1055-1056, and page 15 of the geotechnical report. H. The micropile forces shown on pages 1047-1048 are strength level forces (The sheet header is mislabeled as service level forces). The micropile design capacities shown on 7/S-401 are service level forces and are equivalent to the strength level forces divided by 1.5. For clarity, the affected calculation pages have been corrected and resubmitted with this response letter. iii. Verify the correct micropile types are iii. (4) micropiles on plan were labeled specified for each location on Sheet S- incorrectly and have been corrected. 200. The revised sheet is included with this response letter.
