Questions Answers

In water treatment of closed loops, the chemistry requirement is dependent on system volume. There is very little – if any – data as to the water volumes being treated in the various closed loops on campus. Is there data that can be shared to allow us to much more accurately predict chemistry use? Many times, these volumes can be determined using techniques that are common in the industry – salt testing or initial and resultant chemistry concentrations.

(We can use the pump recirculation rates as an estimate – but that can vary significantly.)

There is no specific data relative to system volume.

The following provides a summary of the pump recirculation rates for the various buildings/systems:

1. Bldg. 28 – Htg. – (1) @45 gpm

2. Bldg. 39 admin. – Htg. – (2) @ 130 gpm

3. Bldg. 39 admin. – Clg. – (2) @ 138 gpm

4. Bldg. 39 program – Htg. – (2) @ 150 gpm

5. Bldg. 39 program – Clg. – (2) @ 138 gpm

6. Bldg. 41 – Htg. – (2) @ 450 gpm

7. Bldg. 41 – Clg. – (2) @ 630 gpm

8. Bldgs. 88, 129, 130, 132, 133 – Htg. – (1) each at 22 gpm There is no data available for Bldg. 39 center section heating, Bldg. 39 data closet PTAC’s, or Bldg. 77 heating.

Perhaps a list of the inhibitor chemistry that was used by the current vendor is available that could assist in determining a more actual chemistry need for these loops. Is there any Time/Material (T&M) data that can be provided?

If we understand that 8 pails total were used from the current product – we can bid accordingly.

A T&M for the Bldg. 39 South Side Chiller indicates that 150 gallons of propylene glycol with phosphate used as the inhibitor was used, there is no specific amount of phosphate in the mixture but the facility believes it was premixed with the glycol.

Is there a copy of a few service reports that can be shared? This data would assist us in understanding if the systems require excess chemistry, due to leaks or other issues in the vast system. It would also confirm what the current corrosion inhibitor is – we assume it is nitrite.

There are no service reports available to assist with determining excess chemistry used due to leaks.

Please confirm that the glycol in use is Propylene Glycol. Is this glycol inhibited – if so with what – phosphate or nitrite [?] We assume PG with nitrite – just confirming.

Propylene Glycol is used in the facility equipment. A recent major fill for Bldg.39 South Side Chiller T&M indicates a 150 gallons of propylene Glycol with Phosphate inhibitor was added. The current contract states Sodium Nitrate should be used when doing a major fill.

Questions Answers

It appears that there is some “duty” for the facility to repair any leaks – due to the fact that we need to provide only 5 gallons of Glycol per year. But if a leak is present – there should be a due diligence to repair the issue identified and prevent an excess of chemistry feed, both from an ethical stance and from a monetary stance. The systems we saw are rather aged in many instances.

The facility will evaluate and repair any leaks, however, if it is beyond the capabilities of the facility, they will request additional services through a T&M / Emergency T&M. Any glycol over the 5 gallons per contract year under the contract provisions may be requested under a T&M proposal.

The bid specification outlines that pot feeders are required in many of the satellite locations. Has there been any thoughts to installing a filter/feeder in these systems to allow for the removal of any particulate matter from these systems [?] The cost is slightly higher for a filter/feeder, yet the benefits of removing particulate matter that can lead to EROSION is worth the price as we chemically treated to maintain CORROSION INHIBITION.

The Contractor shall provide/install a filter/feeder style pot feeder where specified. The Contractor shall also identify any supplemental maintenance required for these units.

It is assumed that all equipment for chemistry feed (glycol feeders, pot feeders already in place) are to stay on site and are owned by

CNYPC.

Yes, the equipment to be installed in Year 1 will be the property of OMH-CNYPC and will remain on site.

In the excel spreadsheet – there is a $5,000 annual Material Allowance. What is that expect[ed] to cover as we submit our bid? Is this for potential chemistry needed – over and above expected – is it for potential equipment replacement?

The material allowance is for any estimated material costs for Time & Material (T&M) repairs that are not covered under the provisions of the contract. This should not affect the bid as this is a set amount per contract year for items not required to perform routine PM tasks that fall under the PM unit pricing bid (i.e., soft parts).

On page 43 of 69, what is “MS” in the column for July for System 39 and 41 Chilled Water System mean?

“MS” indicates Mid-Season Water Treatment PM, performed in July.
