1. Section 7/S302 calls for #4 x 6'-0" @ 16" over beams AND girders in the SOMD. We are used to seeing these

bars over girders only. Can we get verification that rebar over beams is actually what the engineer wants? If

bars ARE required over beams, can we provide the steel in that direction as continuous? The 6'-0" bars would

actually overlap at each end. Supplying these bars as continuous would be much easier to install (which would

save some $$$), and would require less rebar to be fabricated and delivered (which would also save some

$$$).

1. Good afternoon. I have a question on something I found in the specs for this job. Under section 072119.19

Polyurethane Foam Insulation, it has a section that describes the Air/Vapor barriers, it calls out in that section

that all air/vapor barriers must be installed by a certified and licensed installer, and all workers installing the

air/vapor barriers must also be certified. I wanted to see if you could clarify this or get an RFI in asking the

question of does this include under slab vapor retarder. The section says it includes under slab vapor barriers.

However in the 033000 section no such requirement is shown. I have never heard of needing to be certified to

install poly, but nothing surprises me much anymore. Feel free to contact me with any questions or concerns.

Also what is the last day to ask questions and get an official response.

a. Answer: Underslab vapor barriers are part of Section 033000 and are not part of Section 072119.19, therefore qualifications shall be per the section associated with the work. Underslab vapor barriers
