1. CM RFI #1

Bid Package 2.08 - Aluminum Entrances, Storefronts and Curtainwall

Question:

a. BP 2.08 lists the inclusion of Spec. Section 07 42 43 - Composite Metal Wall Panels. This section is not included in the project documents. However, there is a Section 07 42 13 - FormedMetal Wall Panels. Is this the section we are to include?

b. There are a number of inconsistencies regarding the aluminum entrances.

1. Section 08 41 13-2.05A1 notes the doors to be 1-3/4" thick, while section 08 41 13-2.05A2lists the Basis of Design as EFCO’s Thermastile Series D302 Medium Stile. The EFCOD302 is a 2" thick door, and i’s Kawneer equivalent is 2-1/4" thick. Are we to provide astandard 1-3/4" door, or 2-2-1/4" thermal door?

2. In consideration of the above question, please advise on the usage for interior aluminumentrances, where 1-3/4" thick standard doors are appropriate with mono-lithic glazing.

3. The specifications noted above call for a Medium Stile door, which has top and verticalrails that are 3-1/2" wide. Door Types D5 and D6 on the Door Schedule (A-601) note a stilewidth of 6". This is not available option, as wide stile doors have a stile width of 5" Are weto provide a 3-1/2" wide, medium stile door as specified, or a 5" wide stile door as appearsto be the intent of the depiction on the door schedule?

c. Curtain Wall types 7 and 15 note “2x2 horizontal aluminum battens.” There are no detailsreflecting the anchorage of these to the curtain wall system. Could further details please beprovided?

228. CM RFI #228


Question: CM RFI #88, part a, did not receive a clear response. It is still ambiguous if we arebeing directed include the cost to excavate to elevation 23.0 or if we are allowed to interpret forourselves where competent natural soil is. For example, boring MM-13 is in the center of the



building and describes natural dense sand and gravel at elevation 25.5. We wouldn’t includeremoval and replacement of soil deeper than this unless specifically directed to. Please clarify, areall bidders being directed to include removal and replacement to elevation 23.0? Or, are all biddersbeing directed to include removal only down to competent soil?

Response: Bidder to excavate to the proscribed depth.
