QUESTION: During our pre-bid meeting it was discussed that any alternates needed to be approved ahead of time—in section 23-81-01 under part 2 products list Manufacturers Carrier, Daikin, and Trane—the drawings have Chillers listed on the mechanical schedule as Daikin.
 
My question is if we offer an alternate other than what is on the Drawing Schedule- do we need to submit submittals for other manufacturers even if its mentioned in the project manual?

RESPONSE: The scheduled manufacturer (Daikin) as noted on the drawings is the basis of design unit. Carrier and Trane are acceptable alternates (as specified) as long as they meet the performance requirements of the Basis of Design unit scheduled.
