A: Numbers are approximate:

-850 ton- 2100 gal.

-500 ton- 1600 gal.

-500 ton- 1600 gal.

-335 ton- 1600 gal.

-335 ton- 1600 gal.

-inside sump for walk-ins- 200 gal.

Q: Are the Condenser and chilled water systems metered? Can you provide readings?

A: Yes, systems have water make-up meters on them.

Building 1- 500-ton condenser flow rate is 1215 GPM Building 28- 850-ton condenser flow rate is 2550 GPM Building 1 chilled water flow rate is 2400 GPM Building 20 chilled water flow rate is 1086 GPM Building 20 condenser flow rate is 1510 GPM

Q: Does the VA intend to lease or own the equipment?

A: The VA intends to lease the equipment.

Q: There are different levels of disinfection based on the level of CFUs, the SOW and pricing does not reflect this.

A: The price list shall be modified in section 2. of this modification to reflect the two different types of disinfection Q: What are the current boiler and chiller chemicals being used and what are the current chemical ranges?

A: BOILERS:

pH – 7.5-8.5 triact 1825 is chemical being used Nexguard 22310 – 200-300ppm Sulfite 1720 : 30-60ppm Boiler conductivity – 2000-2500uhmos Conductivity of feed water – 50-100uhmos Alkalinity – 300-900ppm Water hardness – not an issue Soft water make-up - summer: 5,000 gpd winter 10-13,000 gpd Steam poundage – summer:5,000lbs/hr winter: 20K-28K per hour

CHILLED WATER AND CONDENSER WATER

Chilled water- Sodium Hydroxide Solution

- Condenser water scale inhibitor- Phosphono, Butane tricarboxylic acid

- Condenser Water Biocide- Sodium Hypochlorite, Sodium Bromide

- Condenser water microbicide- Glutaraldehyde

- Condenser water (tower) disinfection- Sodium Hypochlorite

- Layup - Sodium Tolytriazole, Sodium Hydroxide

Q: How often do you sample water from the boiler system A: daily Q: Does the vendor need to create their own Maintenance Plan Program (MPP)?

A: No, the vendor can use the existing VA MPP. No need to create a new MPP.

Q: Who will be responsible for submitting required state reporting requirements?

A: VA is exempt from state reporting requirements.

Q: Who is responsible for EPA reporting?

A: The vendor is responsible for submitting required EPA reports.

Q: Does the VA want controllers that perform water testing to include biocide levels and have SIM card data collection?

A: Yes, the VA will change the system requirements to add these features, see section X on this modification.

Q: What biocide feed schedule are you requesting?

A: The VA is requesting that the vendor use a stabilized Bromide as the oxidizing biocide and Glutaraldehyde as the non-oxidizing biocide. There is no specific feed schedules requested. The only requirements are that 1. The schedules are in accordance with EPA and NY State regulations 2. That fungal/bacteria growth is within stated limits of this solicitation 3. There are 0 Legionella hits on an annual basis.

Q: What water sampling does the VA perform on the chilled water and condensing tower systems?

A: Daily biocide level readings and dip slides weekly Q: What are acceptable levels of bacteria and fungi in the chilled water and condensing tower systems?

A: Remediation required at 10,000 cfu/ml or greater Q: Can the start of season cleaning of the condensing towers be started before the start of the season?

A: Yes, the vendor can perform start the start of season cleaning before the cooling season has been announced by the COR.

Q: How much water does the closed loop system make up?

A: -Chiller plants (Bld.#1 & 20 combined): Condenser water usage including makeup and initial fill: approximately 16,000,000 gal/yr.

-Chilled water make up unknown for both systems Q: Is there a filtration system on the closed loop? IF, no does the VA want one added to each of the two systems?

A: No, the VA does not have a filtration system on either of the two closed loop systems.

Yes, the VA would like a bag filter system added to each of the two closed loop systems. This requirement is added to the SOW of this solicitation in section X of this modification.

Q: What is the flow rate for each of these closed systems?

A: Building 1 chilled water flow rate is 2400 GPM Building 20 chilled water flow rate is 1086 GPM Q: What are the guidelines for scale/corrosion for the chilled water and condensing tower systems?

A: Follow industry standards for galvanized towers and steal pipe.

Q: Can you subcontract the work to install the side stream filters on the chilled water systems?

A: Yes, as long as the requirements of VAAR clause 852.219-10 are met 13 CFR §125.6 (1) In the case of a contract for services (except construction), it will not pay more than 50% of the amount paid by the government to it to firms that are not similarly situated.
