Roof keynote 1/A-70-1004 is a <br />gypsum board ceiling with gypsum board underneath that creates a ceiling <br />assembly. For more information regarding note 11/A-70-1002, see referenced <br />section 3/A-70-3001, corresponding referenced section 3/A-70-3002, <br />corresponding referenced section 3/A-70-3004, and tagged Assembly G in detail <br />3/A-70-3004 for additional explanation of the construction gypsum board roof/lid. <br />Q173- Specification section 06 10 00 Rough Carpentry is not included in the project <br />manual. Please provide further information for the miscellaneous rough carpentry called <br />out in various architectural details. Should we assume industry standard materials or will <br />a specification section be issued? <br />Assume industry standard wood materials. These are acceptable as this project <br />is primarily steel and concrete construction. <br />Q174- Is there any Buy America(n) requirement for the project? <br />There are no Buy America(n) requirements for this project. <br />Q175- Specification 31 63 33, Article 2.01.D.1 | Specification requires couplers to <br />develop 150% of reinforcing bar strength. Vendors have informed us that the couplers <br />are manufactured to 125% of the reinforcing yield load. Will 125% be acceptable? <br />Couplers shall develop 150% of reinforcing yield strength due to seismic <br />requirements and importance of deep foundations on this project. <br />Q176- Specification 31 63 33, Article 2.01.D.1 | Specification requires couplers to have <br />current ICC-ES report. The Vendors have informed us that “ICC-ESR report is for <br />couplers that are used in reinforcing steel inside concrete columns, and beams in above <br />the ground building structures. It is not used for below the ground structures, such as <br />shoring, soil nails, and piles.” They will not be able to provide ICC-ES reports. Will a <br />conformance letter from the Vendor be acceptable in lieu of ICC-ES report? <br />Conformance letter is acceptable. <br />Q177- Driven 18” Pipes – The Contractor is worried about vibration impacts to the <br />existing structures. Will it be acceptable to torque-in the piles? If so, will torque <br />measurement be acceptable for quality assurance? <br />The contractor could install the piles using torque, then switch to a hammer to <br />verify capacity through penetration resistance. Section 31 09 11 Settlement and <br />Vibration Monitoring requires monitoring of sensitive structures during <br />installation. <br />Q178 - Section 43 16 23 02 -528 gal inverted sewage bladder tank - Section 2.05.C.2 – <br />Process connection should be 2” ANSI Class 150 flanged in lieu of 2” NPT for more <br />reliable sealing.
