RFI’s

1. Sheet 1AE-102 note 01.02 references note 09.01 for more info on flooring. Note

09.01 is a note about ceiling framing. Should this be note 09.02? Correct; Keyed Note 01.02 on sheet 1-AE-102 should refer to Keyed Note 09.02.

2. Sheet 1AE-102 note 01.05 new door at primary icra. Please verify location of this new door. The Primary door for the ICRA vestibule B508A is shown new/used installed within the existing GWB opening. The entire primary ICRA vestibule and temporary ICRA partitions and opening to be installed per the GC’s needs (means and method) and ICRA requirements and submitted for final approval. Note; the Alternate ICRA filtration for Level IV is now located in corridor H509, so the need for a temporary ICRA barrier to Control 1 B509 may not be needed by the GC.

3. Sheet 01-EK-5518, structural engineer to verify reusability of unistrut on site. Will the owner’s structural engineer be responsible for verifying this? This will be the responsibility of GC’s miscellaneous metal fabricator. The AE’s engineer will visit the site once the existing structure is exposed to confirm that the structure in place does conform to the current load requirements, but any minor additions to carry the added 2’ of new equipment rail, will be submitted by the metal fabricator.

4. It was mentioned at the walk through that there is to be very little structural steel added for this project and that it is called out and detailed on the drawings, possible reference note 09.01? Please indicate what drawing shows the added steel and details for this steel. Will this steel be added for both lab’s? See the answer to RFI_003 above for clarification. Lab 2 should not require any additional structural bracing, but this will be confirmed as noted above. See sheet 01-EK-5563 PHILIPS sheet SD4. When the exact location for the support is determined, the contractor’s steel fabricator shall submit shop drawings for approval.

5. Sheet 1-AE-103 detail 5F has a blue line with note #26.09 on it. Please advise what note 26.09 is? Note 26.09 on sheet 1-AE-103 should read 26.07 as shown on sheet

9. It was mentioned at the prebid that there is a laminar system? Please indicate where the information is for the laminar system in the specs and drawings? The laminar Flow system is existing. There are no shop drawings available for this product. The contractor is required to provide a balance report of the existing air flow conditions and final air flow conditions.

10. If the laminar system is new, who is providing the new laminar system? If it is the GC, please provide specifications and drawings to indicate manufacturer and model. Existing

11. If the laminar system is new , who is installing the new laminar system? Existing

12. If the laminar system is existing and is to be modified please provide directions on modifications. Please provide manufacturer contact so that we can make sure we modify per manufacture’s specifications. The laminar system is existing and we do not expect any modifications. If any modification is required, it will be addressed through a change order. The manufacturer for the existing laminar flow system is Chicago Faucets.
