Inquiry #42: 1) Inquiry #3 on RFI’s 1.5.23.pdf – they replaced the metal adjustable shelves which are shown on the wall with reagent shelving (item 2.10A from spec). That is not correct. Reagent shelving are those that are on top of a countertop. Not wall shelving as shown in the elevations. The key note 123553.7 calls out for metal shelving. I think the question was what type of shelving. Wall mounted; free standing like U-Line or Metro type shelving.
2) Per Addendum #1 Plans, Sheet I1-08, Material and finish schedule, Rooms 9-13 note casework as CAB-1 Metal which is correct, but for the counter tops they note WP-1 which is a fiberglass reinforced panels. Spec 123553 calls out for stainless steel tops on all metal casework. Please advise if this is correct?
