About this file

This is a Questions and Answers document from Solicitation 1232SA26Q0302 that addresses clarifications on technical specifications and project scope.

The document resolves three key inquiries regarding facility upgrades. First, it clarifies that the Main Distribution Panel (MDP-2) for the base bid is specified as 2000A capacity with a 1600A 3-phase LS1G main breaker, confirming the facility's stated service upgrade despite discrepancies in the plan sheets. Second, for Option 2, it confirms that the chiller referenced in plan sheet M-102 should be located in the smolt 1 pump room (west of smolt 2) rather than the smolt mixing bay, as the systems are identical in size and a chiller already exists in smolt 2. Third, regarding ozone treatment additions to the parr, smolt, and brood tanks, the answer clarifies that UV lights for ozone dissipation are only required if they existed in the original system design. The centralized ozone dosing system is intended to replace failed individual generators while maintaining similar control and alarming functions, with UV destruct capabilities only included for systems that originally had them. No additional budget allocation is provided for UV light additions to systems that did not previously include this feature.

Requests for Information Solicitation 1232SA26Q0302

Question 1: For the base bid MDP upgrade, the facility folks noted they were upgrading to a 2,000 amp service. The plans only show 1,600 amps for the new MDP2. Are the plan sheets correct?

Answer 1: MDP-2 is intended to be 2000A, with a 1600A 3P LS1G main breaker.

Question 2: For option 2, plan sheet M-102 C-3 and CB-3 in the smolt mixing bay, facilities noted that this should be shown in the smolt 1 pump room (plan west of smolt 2).

Is this correct?

Answer 2: The chiller should be placed in smolt 1 not smolt 2. The systems are the same size and we already have a chiller in smolt 2.

Question 3: Since ozone is being added to the parr, smolt and brood tanks, do the brood tanks need UV lights added inline for ozone dissipation? If so, could a detail or basis of design be shared?

Answer 3: The design intent was to replace the ozone dosing capabilities of the failed individual generators on each system with a new centralized ozone dosing system, with similar control and alarming function on each individual system. If a RAS system did not have ozone destruct using UV in the original design, it was not budgeted as part of this upgrade.
