About this file
This document is a Questions and Answers (Q&A) spreadsheet for RFP 250000003013 from the State of Michigan, specifically involving water treatment services for a facility in Delta Township. The RFP covers water treatment and chemical management for multiple systems including cooling towers, steam boilers, chilled water loops, and associated equipment. The State will require weekly chemical testing, monthly reporting, and the implementation of new controllers for chemical metering, blow downs, and monitoring of pH levels and conductivity. The contractor will be responsible for providing all necessary feed equipment, treatment, test equipment, and supplies. No site survey will be conducted, and testing supplies are covered under the RFP.
The current facility uses municipal water from Delta Township and operates two 27,000 lb/hr turbines running 24/7, with a standalone boiler at 70,000 lb/hr, operating at 125 PSI. The annual water makeup is approximately 17,242,000 gallons across three cooling towers, with about 75% condensate return. The RFP indicates this is a new contract, as no previous similar procurement has occurred. Specific system details remain partially undefined, with several technical parameters noted as "No information available." The contractor will need to provide tower and boiler controllers with LAN connectivity to the on-site control room PC, and maintain water quality standards regardless of specific chemical brands used.

| Q # | Document and Section | Page # | Bidder Question | Response |
| 1 | N/A | N/A | On the cooling tower, I only see one non-oxidizing biocide (predator 1020). Is there also an oxidizing biocide (bromine or chlorine) as well? (asking because maybe this is provided as a commodity from another vendor) | No, there is not an oxidizing biocide presently. |
| 2 | N/A | N/A | Does the State of MI own all the feed equipment for the chemicals. Is the awarded bidder expected to provide any equipment under the RFP? | Contractor will be responsible for all necessary feed equipment, treatment, test equipment and supplies. |
| 3 | N/A | N/A | Can a site survey be set up next week through Heath Miller to review the water treatment systems? | The State does not plan to host a site survey for this procurement. |
| 4 | N/A | N/A | Is the testing supplies covered under the RFP, or do you purchase these separately? (this is if your team, State of MI, is testing on site) | Yes, testing supplies for this contract are covered under the RFP. Any testing the State does separately will not utilize contractor supplies. |
| 5 | N/A | N/A | Do you have any water meter data for the make-up of the steam boilers, closed loop, and cooling towers? If water meter data is recorded, can you provide this information for the RFP? | 17,242,000 gallons/year, all 3 towers. |
| 6 | N/A | N/A | Can you provide a service report from the current vendor or your own if you test on site, so that the testing ranges for the cooling tower, closed loop, and steam boilers can be reviewed for the service and testing requirements for the monthly service visits? | A snap shot of some recent conditions is provided in the table below as an example. It is not intended to represent normal, satisfactory conditions nor is it intended to illustrate all monitoring points, specifications or parameters. |
| 7 | N/A | N/A | Do you currently use corrosion coupons on the closed loop and cooling tower—if so, do you want this service included in the contract? | Corrosion coupons will not be included in this contract. |
| 8 | N/A | N/A | Can the bid results from the most recent previous RFP be made available? | There has not been a recent RFP or contract. Service costs have recently achieved the threshold to justify a contract. |
| 9 | Schedule A | 1,6 | This document says weekly chemical tests and analysis of needed equipment are required, but it also says monthly reports are to be emailed. Are on-site visits required monthly or weekly? | If on-site visits are necessary for the contractor to test and analyze, then weekly onsite is required. An onsite visit is not deemed required to email monthly reports. |
| 10 | Schedule A | 2 | What is the annual volume of make-up water added to the chilled water loop? | For the cooling towers, 17,242,000 gallons/year, all 3 towers. |
| 11 | Schedule A | 2 | What is the source of make-up water for each system (city water, well, softener, RO, etc.) and can you share a water analysis for the source water(s)? | Delta Township, municipal water supply. |
| 12 | Schedule A | 2 | What metals are present in the chilled water loop and the cooling tower systems? | No information is available at the time of this writing. |
| 13 | Schedule A | 2 | Can you confirm the products and their descriptions listed on Page 2 for Chilled Water Loop and Cooling Towers are correct and should not be switched (for example, should products CW-296 and CW310 be listed under Cooling Towers or Chilled Water Loop)? | Brands or trade names are for identification purposes only and do not limit the Contractor to such brands or trade names. Actual water quality standards must be maintained regardless of chemical requirements. |
| 14 | Schedule A | 2 | What is the frequency of operation for the cooling towers (for example, do all cooling towers run 24/7/365)? | When the load in the summer dictates, we run 2 towers at a time. in the winter months only one is used generally. |
| 15 | Schedule A | 2 | What is the average steam production annually in lbs/hr of steam? | No information is available at the time of this writing. |
| 16 | Schedule A | 2 | Do all 3 cooling towers share common piping or a sump, or all they all independent? | There is an equalizer pipe between them all but we isolate tower 3 in the winter for the free cooling. |
| 17 | Schedule A | 2 | Are there refillable tanks onsite for any of the chemicals? If so, what are their volumes? | 275 gallons |
| 18 | Schedule A | 2 | What is the horsepower, frequency of operation, and percent load of each boiler? | 2 turbines at 27,000 lb/hr they run 24/7. Stand alone boiler is 70,000lb/hr |

| 21 | Schedule A | 2 | What is the steam pressure(s)? | 125 PSI |
| 22 | Schedule A | 1 | The document mentions needing controllers for the cooling towers. Are these controllers replacing existing controllers? | Yes, for metering. Will need Tower Controllers for Chemical metering pumps, blow downs, and injection pumps that also monitor Ph level. Will need Boiler controllers to monitor conductivity, blow down, usage, and Ph. This will also need to have a LAN connection to the onsite Control Room PC. |
| 23 | Schedule A | 1 | This document mentions needing controllers for the boilers. Are these controllers replacing existing controllers? If so, will any of the current equipment remain connected to these controllers, such as blowdown valves, conductivity sensors, pH sensors, etc.? | No |
| 24 | Schedule A | 2 | Is there a deaerator or feedwater tank for the steam system? If so, what temperature and pressure does it typically operate at? | 240 degrees at 10lbs |
| 25 | Schedule A | 1 | Do reagents and testing equipment need to be provided as part of this RFP? If so, is there currently any testing equipment that is facility-owned? | Contractor must provide testing equipment and supplies to perform cotract activities.
