This will total 71 total samples to be collected on a quarterly basis (284 samples yearly).

Deliverable:

B. Provide a copy of the test sample results

A.3 Water Testing:

The Goals of the program are:

· Minimize corrosion, fouling and biological growth, thereby optimizing water and energy use and minimizing maintenance and equipment replacement.

· Monitor program results and make appropriate recommendations.

· Train plant personnel on the implementation and control of the program.

· Utilize state of the art water treatment programs at a competitive price.

The systems to be treated, and pertinent operating data, are listed in Attachment A. Required services are listed are listed in Attachment B. Vendor qualifications are detailed in Attachment C. Finally, Attachment D contains the bid submittal form. All information requested on the specification submittal form must be included for the proposal to be considered. If other services are available at additional charge, or if there are any other comments, please attach extra pages as required.

The VA is requesting a price to provide the chemicals and services outlined in Attachment B. The quote means that all handling of chemicals, testing, dosage adjustment and pump and controller maintenance will be done by the vendor for the cooling towers and closed water systems. Testing will also be performed by plant personnel. In addition the vendor will train operators and management about the cooling tower controller adjustments as well as the boiler blowdown controller adjustments.

The term is for one year plus four option years. The VA will be billed monthly for 1/12 of the contracted price. This is a “lump sum” price. No other charges will be considered unless agreed upon in writing after a thorough review by the VA. Changes will not be considered unless plant changes necessitate a variation of more than 20% of the contracted price. For example, if there were large system water losses and continued treatment was requested, there could be a much larger use of chemical than expected. On the other hand, if a major system were shut down there would be a much smaller usage than expected. If these situations varied by more than twenty percent of the anticipated use (cost). Consideration would be given for additional billing or rebate. An exception to this would be if recommended changes would result in additional savings of water, chemicals etc. In this case a sharing of these savings would be discussed.

It is the responsibility of the vendor to visit the facility and take whatever samples are necessary, gather data and ask any questions to assure themselves that they have sufficient knowledge of the systems so that an accurate bid can be submitted. It is also the responsibility of the vendor to consider the variations in water quality, temperature and minor problems that occur during a treatment program. These should be factored into the bid. This document was written in very specific terms to clearly outline the required minimum services expected from the vendor. Additionally, the vendor must use all water treatment chemicals on-site at the beginning of the contract.

The iChlor monochloramine systems are preferred to be used to provide a healthy amount of monochloramine into the domestic water of these respective facilities. The Contractor may use an alternative monochloramine system than the existing iChlor monochloramine systems given that the monochloramine systems provide an alternative that works in a similar way as the iChlor monochloramine systems. Specifically, the alternative system must be able to control microbiological growth in domestic water and control the legionella bacteria. Controlling legionella bacteria is of high importance, as it can cause harm to immunocompromised people and the hospital contains an in-patient elder care facility. Since the iChlor monochloramine systems are already installed and functional, any alternative implementation should come with its own installation and removal of the current system at no cost to the Government.

Quarterly: Within 90 days of award, the first quarterly preventive maintenance inspection shall be conducted on the already-installed iChlor monochloramine systems, and quarterly thereafter.

Monthly: Within 30 days of award, the first monthly preventive maintenance inspection shall be conducted on the already-installed iChlor monochloramine systems, and monthly thereafter. The monochloramine systems shall be tested monthly to ensure a healthy amount of chemistry is in the systems. Monthly logs shall be provided to the boiler plant technicians and Safety Officer to ensure complete transparency within the monochloramine system. The amount of chemistry to be safe must be determined by the most current EPA regulated measurements.

Weekly: Any emergency alerts or abnormalities in the monochloramine system shall be reported to Safety/Boiler Plant Supervisor on a weekly basis.

Deliverables:

E. Provide monthly logs.

F. Report emergency alerts or abnormalities.

A.6 Water Testing: Temporary Critical Water Wash System:
