QUESTIONS & ANSWERS

1. Will glycol system need rebalancing?

No. AHU-1 and AHU-2 are refrigerant-based systems and are not connected to the hydronic loop. AHU-3 and AHU-4 will reuse the existing indoor DTS/DTR chilled-water system, which does not contain glycol. The contractor shall balance the new AHU-3 and AHU-4 coil water flows to the scheduled design values.

2. What is the required floor protection system to protect the gym flooring?

See attached Addendum 01 sheet MD-101.00 dated 9/23/2026

3. Please confirm there is no masonry work for any duct work modifications?

See attached Addendum 01 sheet MD-101.00 dated 9/23/2026.

Also, new units can be provided in shipping splits to allow the equipment to be brought into the gym through the available double doors and assembled in place. The design team has coordinated revised equipment selections accordingly. Please see the attached updated selections, along with the shipping split summary, which identifies the approximate dimensions of each individual section for rigging and access coordination.

4. Drawing C100, please confirm how many rows of snow guard are to be installed. Plans show double row at each location.

The snow guards have (2) bars on a single retention bar, (8) rows total.

5. Please confirm that all low voltage cabling for the BMS system will be handled by contractor.

Confirmed. All low-voltage wiring and cabling required for the BMS controls and integration shall be provided by the contractor.

6. Per the specifications, the existing steel joists are required to be reinforced. However, the drawings do not indicate the required reinforcement details, quantities, or existing conditions of the joists.

Please clarify.

The design team has had a structural engineer check the loading for the new units, and confirmed that there will not be any reinforcement needed.
