Water Treatment Questions and Responses No.: 1

Question 1: What is the current value of the contract?

Response: Base Bid Amount $209,908.50

Question 2: How long has Klenzoid been providing services to the University under this contract?

Response: Five (5) years.

Question 3: Section K10., Total Water Volume Calculations – Since this is a one-time event, will the University be purchasing the chemical/labor required for the volume calculations separate from the contract?

Response: No, this service should be included in the contract.

Question 4: Section K11 and 12, Power Plant Data and Power Plant Operating Data –

The information provided for the Power Plant/Boilers is the type of information needed for contractors to calculate the annual chemical requirements. Is there any data/operating data for the Cooling Towers, i.e.

System tonnages, year- round or seasonal operation, etc., that will allow us to calculate annual chemical requirements?

Response: The system tonnage is 6000 in the Central Power Plant and the Chillers operate year-round. The cooling tower (4 cells) at the Power Plant is in operation year-round. It is an Evaptech, model # EC424. Also see Exhibit 3.

Question 5: Is there any current data, i.e. estimated volumes, for the closed loop systems? Can the University provide the square footage of each of the buildings as a means to estimate the requirements for the closed loop systems?

Response: See the attached Exhibit 3 and Exhibit 2

Question 6: What is the age of the softeners on site?

Response: Installed in 2019

Question 7: Scope of Work, Section D., Responsibilities and Task – Contractor is to provide all labor, material, supplies and equipment necessary to perform all chemical treatment. During the site visit it was reported that the incumbent owns all existing equipment; if another contractor is awarded the contract, they will essentially be required to install all new equipment.

The incumbent has a distinct advantage; if the University wishes to increase the degree of competition on this contract, there needs to be more of a level playing field. Can the University please address this?

Response: TU does not provide supplies or equipment to the contractor, and as indicated in the solicitation, it is the vendor’s responsibility to provide all labor, material, supplies and equipment necessary to perform under the contract. Additionally, and for transparency, the current base bid amount is known. Please bid accordingly and as deemed appropriate for your company.

Question 8: Chiller inventory by building, can you please provide tonnage and quantity of chillers located across campus.

Response: See response below:

• CFA (2) Carrier 19XR3132=250 Tons ea.

• Union (2) Carrier 19XRV4142=500 Tons ea.

• SECU Arena (2) Daikin WME0500S=500 Tons ea.

• SECU Arena (1) Daikin WMC048DDSNA=400 Tons

• West Village (1) Daikin WMC290D=290 Tons

• Media Center (1) Carrier 30HXC=60Tons

• CHP (2) Trane CVH410-410 Tons ea.

• CUPA (3) 1500 Tons e

Queston 9: Cooling Tower Drainage Schedule. Which cooling towers are drained annually as part of routine maintenance or seasonal shutdowns and which cooling towers remain online year-round?

Response: All Cooling Towers are currently drained except for 10 West, CHP, and the Central Power Plant. These Cooling Towers will remain in service.

Queston 10: Can you provide one year’s worth of make-up water readings for the main plant steam system, the main plant cooling towers and all steam boilers horsepower ratings?

Response: See response below:

• Cooling Tower Make Up – 10,523,595 gallons

• Chilled Water Make Up – 16,545 gallons

• Steam System Make Up – 3,481,000 gallons

Queston 11: Cooling Tower Tonnage (CWS tonnage) for each cooling tower covered under the program.

Response: See response below:

• CFA (2) Carrier 19XR3132=250 Tons ea.

• CFA (1) Trane CVHF049F= 500 Ton

• Admin (2) York YSCBCAS2CGDS 200-300 Tons ea.

• Union (2) Carrier 19XRV4142=500 Tons ea.

• SECU Arena (2) Daikin WME0500S=500 Tons ea.

• SECU Arena (1) Daikin WMC048DDSNA=400 Tons

a. Cooling tower loops

b. Closed-loop chilled water systems

c. Closed-loop heating system

d. Dual-temperature systems

Response: See chart in solicitation

Queston 13: Boiler specifications and operating parameters, including operating pressures, temperatures, and any redundancy or staging details

Response: See Exhibit 3

Question 14: Chemical feed and control equipment currently installed, including make/model of controllers, pumps, monitoring devices, and any web-based/remote monitoring capabilities in place.

Response: It is the contractor's responsibility to verify the equipment needed for each building during the site visit.

Queston 15: Inventory of treatment points, i.e., a list of buildings and systems included in the program (boilers, cooling towers, closed loops, etc.).

Response: See chart in solicitation

Queston 16: Access requirements and any site constraints (e.g., restricted areas, after-hours access, parking/loading limitations, or specific safety/permits needed for service visits).

Response: Please see solicitation regarding parking. All others shall be coordinated with the Project Manager.
