73. Notice No. 2 Q&A #64 TOPIC: Additional undercut volume below proposed subgrade until at least 95% maximum dry density (MDD) is achieved.

COMMENT:

Apology, the question had nothing to do with MEC and more to do with the method of payment in the event that soft yielding material was encountered within the BLDG footprint & paved area that warranted additional over-excavation up to 2 feet below the proposed subgrade elevation before 95% MDD could be attained. We respectfully re-submit the question.

ANSWER: Response is deferred.

74. Specification Section 31 32 23 Foundation Drilling and Grouting & Price Proposal Schedule page 3 & 4 of 6 Item 0001AC & 0001AD Additional exploratory holes & grouting The language used in SLIN 0001AC & 0001AD lends itself to a misinterpretation. The 0001AC description refers to drilling for ADDITIONAL grout holes while 0001AD is to inject grout in ALL exploratory holes.

1. Please confirm that items 0001AC & 0001AD is intended to cover all the drilling & grouting requirement called out specification 31 32 23.

2. Please advise approximate number of boring locations for items 0001AC & 0001AD.

3. As noted the grout volume given on item 0001AD of 112.5 CY is more than enough for the boring hole under item 0001AC of 3,320 LF. Please advise if the total volume is net or includes a wastage factor, and if so, what that factor is.

ANSWER: Response is deferred.

Kindly clarify if paragraph 3.5 is applicable for wall coating application procedure and if not, we are requesting for the correct specification for the wall coating.

ANSWER: Para. 3.5 is applicable for wall coating application, but para. 3.5.2 through 3.5.5 are to be revised in Amendment 0004.

76. Precast wall foundation plan per drawing SB101 Precast Wall Foundations along grid line A & E, between grid line 1-10 The exterior wall section detail A1 on Drg S-504 re-issued in Amendment 0002 shows a new-clouded reference (Note 2) to an alternate footing detail on C2/S-505. Detail C2/S-505 appears to an interior wall footing detail of 4”-10” width and not an exterior wall footing section of 10”-0”.

Please confirm if our understanding is correct that the required size for the precast exterior wall foundation at warehouse area is 10 feet wide x 3 feet depth.

ANSWER: Precast wall foundation along grid line E, between cols. 1 & 2, is to be width as shown in A1/S-504.
