Past Performance requires three projects of similar size and scope, and indicates that, “projects should demonstrate experience working in: an operating urban campus; constrained sites with limited laydown area, and; adjacency to public areas and animal habitats.” Please confirm that the three projects can be adjacent to public areas and/or animal habitats.

Three projects can be adjacent to public areas and/or animal habitats. Higher consideration will be given to projects adjacent to public areas and animal habitats.

2 Abacus Sports I just left you a message regarding the Cheetah project that is out to bid. Your specs and finish schedule call for our Padenpor DLX, but spec seems to be written around a Stonehard product with using Stonclad epoxies and mortars. It reads like the specification have been mixed together.

Which product do you want for these floors ((FLR – 2). Assuming you do want our floor, what thickness do you want?

Please see attached our flooring spec. Padenpor is available in different thicknesses.

Please note the two specs and BOD for each:

1) RESINOUS FLOOR SYSTEM BASIS OF DESIGN STONEHARD STONE CLAD GR, Spec 09 6723

2) RESILIENT FLOORING BOD ABACUS PADENPOR DLX™ – 9/16" CUSHIONED ZOO FLOORING, Spec 09 6567 See sheet A501DT for details

3 WM Schlosser 1.Spec Sec on 051200 Structural Steel Framing (part 1.06-D) calls for “A qualified steel fabricator that is accredited by the International Accreditation Service (IAS) Fabricator Inspection Program for Structural Steel”. Since most local fabricators do not have this IAS accreditation, can this requirement be waived? If not, can you add “or AISC Certified Fabricator Category BU” to this requirement?

IAS and AISC BU certified fabricators are acceptable

It is acceptable to lower the requirements to include AISC Certified Fabricator Category BU (Building Fabricator). - AE / McM

4 Whiting Turner Executive Order (EO) 14603 indicates that all federal projects valued at $35 million and above will require a project labor agreement (PLA) unless a federal contracting agency expressly grants an exception.

Please provide operator rates for use on the proposal.

Both Davis Bacon Wage Determination DC20240002 (Building) and DC20240001 (Heavy) shall apply. Prior to Award, the most current version shall apply.

63 Whiting Turner Specific Notes 3 and 9 from drawing P401, and specific notes 6 and 7 from drawing P402 reference to see the "Zoo Consultant Drawings." When comparing the drawing sets, this note seems to be referencing the architectural drawings. More specifically, the barn floor plans (A-001 & A-002), as they show details on the installation of the animal drinkers in the barns. Please confirm “Zoo Consultant Drawings” is in reference to these architectural drawings.

This is correct.

All drawings in sequence A 000 FP Key Plan to A016 DT Cheetah Chute are the zoo consultant drawings. A/E

64 Whiting Turner Referencing the solicitation, Section C.2 SCOPE OF WORK notes “the structural foundation for the stations must be replaced and raised up…” (page 16 of 183). However, details 4/S503 shows the foundations and new floor elevation being lowered. Please confirm this detail.

66 AMPP Basic Coating Inspector

Due to high VOC content and irregular supply chain of coatings specified in 099611, can the coating system specified in 099600 be used for the areas called to be coated with 099611?

All bids should be based on the coatings per the Contract documents. - A/E These coating align with SI NZP standards

67 Consigli Concerning the sheet metal flashing details specified for the A500’s, they require 12-gauge stainless steel, essentially plate metal. It's worth noting that a standard sheet metal brake may lack the capacity to bend metal of this thickness. Moreover, this option is notably more expensive, approximately 25 times the cost of standard 24-gauge sheet metal. This seems to be an oversight.

Please clarify.

Drawing / spec reference: A500's

The A 500 set has multiple types and gauges of steel specified within that series.

1- When a gauge of flashing is not specified, defer to the spec 07 7100 2- A 503 DT 3, 4, 5, 6, 7, 8, 13 have a typo and should read “22GA SS FLASHING” 3- A 502 DT 1, 2, 10, 11, have a typo and should read “22 GA PTD. METAL FLASHING COLOR TBD
