1 Since the combined project magnitude for both is $18M-$24M, can relevant projects under $10M be considered as acceptable “Past Performance” examples?

SI's intent is to award a project in the $18 to $24 million dollar range. Past performance needs to be in that range to be acceptable. Two $10 million dollar projects will not be acceptable to demonstrate adequate past performance.

2 Will receipt of the multi-year funding increments cause any anticipated delays in the project?

1 The specifications of both South Entrance and the Baird Auditorium AHU Replacement call for the structural steel fabricator and the structural steel erector to be AISC-certified companies. As the amount of the new structural steel work is minimal, can the requirement be modified to companies that follow and abide by the AISC guidelines for steel fabrication and erection?

No, the structural steel fabricator and the structural steel erector shall be AISC-certified companies as defined in the specifications.

7 Note on drawing S111 and 7/S501 call for inspection of CMU knee walls under granite pavers and replacing with concrete knee walls, if necessary. How can this work be quantified at bidding stage? Would it be possible to provide a quantity for all to include?

The original knee walls below the stone paver joints are multiwythe brick masonry, not CMU as stated in this question. For bidding purposes, assume half of the existing masonry walls below the steps will need to be replaced with concrete. This is approximately 13 meters (43 feet).

5 Spec section 129300 provides dimensions for the granite Bird Bath as 24”x24”x18”high.

The listed manufacturer does not provide in these dimensions. Please provide desired dimensions and quantity, as this is not shown on the plans.

Bird bath dimensions are nominal dimensions for the extents of the form of the bath. These are the desired dimensions and the two required are shown on LP451 and LP452 as “GRN BATH.” The intent is for this to be a solid (heavy) stone one piece bath.
