DQ 27-0005 Boiler Chemicals & Treatment Services – LCF

Vendor Inquiries & Responses (Q&A)

1. The dixchlor and dexichlore are the drinking water chemicals. They have zero influence on the HVAC Chemistry and the State drinking water laws require those to be addressed by your licensed drinking water operator. In the past, you have purchased those from another source on a separate bid. They would most likely been excluded from the HVAC chemical bid. This is also true of the salt for the water softeners. That's an open market item that they regularly put out on a separate bid for folks that specialize in that commodity.

Answer: Salt will be purchased from another source, and pre-softening of the water will be done by CDOC Limon Facility Staff. Bids do not need to include Salt or Water Softening services.

2. This facility has historically maintained the water treatment SOPs in house with Boiler house Staff. They have relied on the WT vendor only for materials and technical troubleshooting. The bid scope is for a monthly Water Treatment Service Contract. Please clarify if the Scope is to include monthly services or not?

Answer: Boiler water treatment, testing, consulting, advising, and chemicals will be done on a monthly basis going forward at Limon Correctional Facility. Staff will make arrangements with the Awarded vendor to schedule these services.

3. It is understood that line items are requested by the RFP. Are you expecting the final costs estimates to reflect the line-item costs only? (buying as needed); Monthly service contracted costs? (Monthly Set cost); or annual Contracted Costs (such as a blanket PO)?

Answer: Buying as needed per the testing and laboratory results, chemicals will be added by Awarded vendor at time of service, and staff will add chemicals at other intervals of time based on the direction/advise of the Awarded vendor. Pricing should be provided on the costs per chemical, testing supply, or service as it would be charged during the chemical treatment and test services. Per item cost, annual cost is unknown until the chemicals are needed.

4. Reference: Section 1.A of the Statement of Work requires regularly scheduled testing of water chemical composition; adding or adjusting water concentration levels; and inspection of boiler functions, heat pumps, tubes, filters, gauges, and controls. Please provide clarification on the following items:

A. Boiler Functions: What specific actions are required for the inspection of boiler functions?

Answer: Inspecting the tubes for corrosion and calcium build-up due to not enough water treatment or the corrosion of the water tubes due to not enough or over-dosing the system with too much chemical that it starts corroding the water tubes / dissolving the tubes which leads to thinning / rupturing of the tubes.

B. Heat Pumps: What are the service requirements for heat pumps? Please identify the number of heat pumps, their locations, how they are accessed, and the expected level of service or inspection.

Answer: We do not have heat pumps. We have hot water valves that actuate to adjust to the setpoint temperature. The amount of hot water going in to the hot water coils inside of the air handler that produces heat. Its on a closed loop boiler hot water system. The water is circulated through each coil and returns to the boiler and reheated.

C. Tubes: Please clarify what is meant by “tubes.” Does this refer to boiler tubes as well as chiller tubes? What is the expected service or inspection requirement for these tubes?

Answer: Our chillers have condenser tubes that need to be inspected yearly. They need to be cleaned by tubing the chiller condenser tubes with a chiller tubing machine. They need to be inspected for any buildup and or corrosion as well as a conductivity test done on the copper tubes that are in the condenser to tell the thickness of the tubes. There are also tubes on the boiler, we have water tubes as well as fire tubes so the boiler tubes are brushed and vacuumed after inspection and the boiler needs to be drained down and inspection cover removed on the water side to inspect the calcium build and or corrosion on the water side of the boiler water tubes.

D. Filters: Please clarify what is meant by “filters.” During the Site Visit, filters were not observed. What types of filters are included, where are they located, and what is the expected service requirement?

Answer: Filters are to the left when you walk in to the pump room and the softeners are on the right. As you walk in the pump room, filters are green sand filters. They only require service replacement every 10 – 15 years.

E. Gauges: Please clarify which gauges are included in the scope of work. What is the expected service requirement for gauges, including inspection, calibration, repair, replacement, or reporting?

Answer: We have gauges on everything that has any pressure or liquid going through

it. We have meters on all makeup water for boiler and chillers and water softeners.

Gauges are often-times due to the fact that they are typically cheaper to replace than to repair and can not be calibrated. Meters are unable to be calibrated due to being sealed with the exception of the conductivity and PH meter connected to the outside chemical station in the chiller room.

F. Controls: Please clarify which controls are included in the scope of work. What is the expected service requirement for controls, including inspection, testing, adjustment, repair, replacement, or reporting?

Answer: Chiller / boilers / connected controls

G. Reference: Section 2.G of the Statement of Work. 1. Water Softener System: Please clarify the expected scope of work for the water softener system. Is the contractor responsible for providing salt, service, or any other labor or materials associated with the water softener system?

Answer: (To our understanding tri-state commodities will still handle salt / please verify if possible)

5. Reference: Section 3.A.i–xi of the Statement of Work:

A. A.Inhibitor: The Statement of Work references 54-gallon barrels. How many 54-gallon barrels of inhibitor should be included in bidder pricing?

Answer: 1-2 barrels of inhibitor per year but varies year to year.

B. Annual Chemical Usage: On average, how many gallons per year are used for each of the following: bio-dispersant, sulfuric acid, chlorine, Dexichlore, phosphate chemicals (JTC2015), and cooling tower treatment (8100)?

Answer: Bio-dispertant = 1-2 5 gallon buckets, 6-8 barrels of sulfuric acid, 6-8 barrels of dexichlore, 6-8 barre3ls of phosphate, 2-4 barrels of inhibitor. This is all approximate as it varies by year due to specific needs.

C. Bromine Tablets: How many buckets of bromine tablets are typically used per year?

Answer: 1-2 5 gallon pales / depends on year.

D. Dixchlor 10%: How many 54-gallon barrels of Dixchlor 10% are typically used per year?

Answer: 6-8 barreles / depends on year

E. Water Softening Salt Pricing: How should bidders price water softening salt? Should it be priced by the bag, by the pallet, or by another unit of measure?

Answer: LCF receives softening salt by the ton and has to be capable of being blown off by a semi to the vertical tank that is 15 ft tall.

F. Testing Supplies and Equipment: What type of laboratory analysis is expected? Is testing required to be performed by a certified laboratory?

Answer: Yes, laboratory reports should be provided by a Certified Laboratory.

G. Reports Requested by LCF Staff: Please clarify what is meant by “any reports” requested by LCF staff. What types of reports may be requested, and what information should those reports include?

Answer: Reports of test results / recommendations on water treatment / etc.

H. General Clarification Questions Not Specifically Identified in the Statement of Work:

Heating and Chilled Loop Systems: Are there any current leaks in the heating loop or chilled loop systems?

Answer: Not to our knowledge

I. Sediment Concerns: Are there any known issues or concerns with sediment in any of the systems?

Answer: Yes – current sediment build ups.

J. Cooling Tower System Levels: What are the current iron and copper levels in the cooling tower system?

Answer: Unsure due to not having the equipment to test.

K. Domestic Water Systems: Is the contractor expected to provide any services related to the domestic water systems? If so, please identify the required scope of work.

Answer: (depends on this includes salt)

6. Existing Chemicals and Chemical Feed Equipment:

A. If CDOC awards this contract to a provider other than the incumbent, what will happen to the existing chemicals and associated chemical feed equipment currently onsite?

Answer: Current stock will stay on hand for additional treatment by staff at Limon Correctional Facility

B. Will the incumbent be responsible for removing its product and equipment? If removal occurs, please clarify whether replacement chemical feed equipment should be included in the pricing submitted by other bidders, as this may result in additional costs.

Answer: The chemicals already on hand that have been purchased by DOC, will be utilized based on the advise of the Awarded vendor. Removing or disposing of the already purchased chemicals is not cost effective and will need to be utilized as much as possible to reduce annual expenses. Current equipment for feeding chemicals will be used provided it is owned by DOC. Removal would be determined by staff at a later date.
