STATEMENT OF WORK

Minneapolis Veteran Affairs Health Care System
Chiller and Boiler Water Treatment Services
Introduction:

Chiller and Boilers require the water to be chemically treated to prevent bacteria growth, corrosion, scale deposits and sludge buildup that leads to pitting and deterioration of internal components. This is counter acted by introducing different chemicals into the system. System must be monitored 24/7 to ensure chemicals are introduced into the system as they are needed.

One on site assessment is authorized to evaluate the work to be performed and provide the most accurate price quote. Assessment must be completed prior to the closing date of the solicitation.
Statement of Work:

Contractor is responsible for providing all aspects of water treatment and testing for all chillers and boilers at the Minneapolis VA to counter act the water from becoming contaminated with bacteria and prevent corrosion, sludge and scale deposits.

Contractor shall deliver all chemicals in reusable drums or directly into the on-site storage containers without any assistance from VA employees. Contractor shall provide secondary containment when applicable. Contractor shall provide drums and storage containers.

Chemicals shall be 100% compatible with the 3D TRASAR Controllers that are installed and utilized on the Minneapolis VA Chillers and Boilers.

Service Technician shall perform weekly checks and water testing to ensure water treatment systems are working properly. Technician shall make repairs or adjustments as necessary. Shall provide a weekly service report after visit.

Remotely monitor water treatment systems continuously 365 days a year (24/7). Service technician(s) will be available for emergencies with a response time of less than two hours.
Performance Requirements:

Monitor Total hardness in Feedwater. Advise VA personnel on proper softener //reverse osmosis// monitoring and operation.
Monitor Dissolved oxygen levels in the Feedwater. Provide recommendation to Energy Center Supervisor about requirements for de-aerator inspections and repairs.
Prevent embrittlement of boiler pressure vessels.
Condition the boiler sludge to obtain effective bottom blowoff.
Monitor Boiler residual content of sodium sulfite.
Monitor Boiler phosphate residual levels.
Monitor Total dissolved solids (TDS) in boilers.
Monitor Total alkalinity levels in boilers.
Recommended allowances of suspended solids in boilers.
Boiler polymer dispersant residual, as recommended by supplier, with equal successful results of chemical currently being used by incumbent chemical vendor.
There shall be no pitting corrosion.
There shall be no scale and deposit formation in the boilers.
Control boiler water chemistry to minimize blowdown and thus improve efficiency.
Recommend and provide steam amine treatment to maintain condensate PH levels between of 8.0 10 at each condensate receiver throughout the facility, and in the condensate storage tank in the boiler plant.
Control corrosion rates. Steel corrosion rates shall be less than 2.0 mils per year. Copper corrosion rates shall be less than 0.2 mils per year.
Establish layer of magnetic iron oxide (black or dark gray in color) on all steel surfaces as a corrosion barrier.
Annual Glycol testing.
Deliverables:

Invoicing:

Invoices will be submitted on a monthly basis.

Monthly Testing Requirements:

Condensate return systems: pH, hardness, dissolved iron and copper, total dissolved solids (conductivity), amine. Condensate conductivity at a steam trap near the boiler steam outlet. Test the condensate for pH at representative samples of condensate receivers throughout the facility at least twice per year. Vary the sample sites every year.

Make-up water including soft water, water from reverse osmosis, water from de-alkalizer: pH, alkalinity, hardness, total dissolved solids, suspended solids, and silica.

Boiler feedwater: Dissolved oxygen, pH, alkalinity, hardness, total dissolved solids, suspended solids, and silica. Feedwater dissolved oxygen shall be tested twice per year with oxygen scavenger chemical treatment temporarily suspended so that feedwater deaerator performance can be evaluated.

Boiler water: Total dissolved solids, suspended solids, sulfite, phosphate, and alkalinity.

Continuous blowdown systems: Check calibration and settings monthly.

Chemical feed systems: Advise plant supervisor on adjustments to maintain proper chemical dosage and feed rates and blowdown rates.
Contractor s Proposals:

Contractor s proposal shall provide enough information to indicate that their chemicals are compatible with the 3D TRASAR controllers used on the chillers and boiler.

Provide information that demonstrates the following: The contractor shall have been in business at least five years providing chemical treatment of boiler plant and steam distribution systems similar in design and annual steam production rates to that of the VA facility. Contractor shall provide a list of at least three customers similar to the size and scope of the Minneapolis VA who have utilized the services for boiler chemical treatment for at least three years.

Provider resumes for technicians to indicate they meets the following criteria: One (1) water treatment specialist who has a bachelor s degree in chemical engineering or the physical sciences from an accredited college or university shall be assigned to this contract. The water treatment specialist shall have at least five (5) years successful experience with boiler water treatment programs and shall furnish references from at least three (3) customers who utilize their boiler water treatment programs.

The water treatment specialist assigned must be located within one hundred (100) miles of the Minneapolis VA facility to enable reasonable response times to request for site visits.

The contractor must be able to operate (or continuously maintain a contract with) a state certified laboratory to perform complete scientific analyses of water chemistry, deposits, metallic materials affected by corrosion and provide recommendations for correction of problems related to the chemical and mechanical water treatment program. A Professional Chemist shall supervise the laboratory.
