PERFORMANCE WORK STATEMENT

FOR

MAINTENANCE AND REPAIR SERVICES OF PURE WATER SYSTEMS

1.0 BACKGROUND

The Beltsville Agricultural Research Center (BARC) is part of the Agricultural Research Service (ARS), U.S. Department of Agriculture (USDA). BARC is situated about 15 miles northeast of Washington, D. C., in Beltsville, Maryland. Maintenance and repair services are required for pure water systems at this facility. These systems include reverse osmosis and deionized water systems with distribution systems.

1.1 SCOPE OF WORK

2.0 PERFORMANCE REQUIREMENTS

USDA Performance Work Statement

2.0- 2 Maintenance Work Schedules

The contractor shall submit with their proposal a maintenance work schedule for each building pure water system. The contractor work schedule shall identify a monthly frequency per system and shall identify the performance tasks for maintaining each specific system for that month/quarterly/semi-annual/annual.

2.0-3 Contract Switch Over Contractor shall inspect all systems within the first 10 days of award of to ensure pure water systems are in proper working order and notify the COR of any deficiencies in writing within the first month of award. The tank switch over required by this contract shall be coordinated with the COR and the former contractor.

1. An inspection/maintenance/repair system covering all required performance tasks; a method of identifying deficiencies in the quality of services performed; and a list of corrective action or measures used to prevent deficient or unsatisfactory performance.

2. The contractor shall maintain a log book system at each site for maintaining a record of all inspection reports/notes. The contractor shall submit a hard copy of all inspection/maintenance/repair reports to the government COR. The reports shall be hand delivered to the government’s COR’s office.

The Quality Control Plan shall be submitted as part of your proposal.

2.0-5 Emergencies

Emergencies are defined for the purpose of this contract as events that occur outside of normal working hours that require immediate attention (i.e. situations involving research, large system leaks, other items identified by the COR as emergencies). The contractor shall respond to emergency requests made by telephone by the COR or an alternate within 2 hours during normal working hours.

2.0-6 Maintain water quality at 10 Megohm-Cm on all Reverse Osmosis and Deionization Systems.

2.0-7 Reverse Osmosis membranes shall be replaced at the contractor’s expense, when reject rate drops below 85 percent.

2.0-8 Pure water systems shall be maintained in accordance with the manufacturer’s instructions.

2.0-9 Replace mixed bed Deionizers in the building systems when required.

2.0-12 Replace ultraviolet lights when needed.

2.0-18 Perform bacteria counts and total organic counts (TOC). TOC sampling will be performed either on line or via a grab sample. Grab sample shall use low TOC certified vials or containers certified to less than 10 ppb TOCs. On-line and grab samples will be taken after a flush cycle to assure that a representative sample is taken. Samples will be analyzed using a broad range analyzer that is routinely used to measure deionized water. Analyzer will be capable of providing a measurement within 1 % of the IC value and will be capable of providing accurate results in the 10-100 ppb TOC range.

2.0-19 Monitor permeate and reject water quality.

2.0-20 Test feed and product water for total dissolved solids, calcium hardness, ph, iron, and colloidal material and record.

B. The contractor shall be responsible for any individual repair and/or replacement part or equipment including pumps, motors, and reverse osmosis circuit board that needs to be made to the pure water system up to $1,000.00. This shall include parts, materials, supplies, shipping, and labor necessary to fix the system and put it into full operation.

C. The contractor shall notify the COR of any equipment and individual repairs needing to be made and expected to exceed $1,000.00 prior to purchase and submit a written proposal to the COR. The COR shall notify the CO.

D. Individual repairs anticipated to be greater than $1,000.00 shall be provided by the contractor on a negotiated basis, meaning the contractor must submit three quotes obtained from three different sources for any repairs and/or equipment that is over $1,000.00 dollars. The Government will consider the lowest priced technically acceptable quote however in the event the lowest priced quote is not from the contractor’s recommended source, the contractor must submit with their recommended quote a written justification stating why the lowest price quote is not acceptable. The Government will only be responsible for costs over and above $1,000.00. The contractor shall be responsible for the first $1,000.00 portion of the cost.

F. The contractor shall repair or replace all equipment/parts on the pure water systems without additional cost to the Government including pumps, motors and reverse osmosis circuit boards for a complete operational system. The contractor shall take special note that some building systems require polypropylene pipe and fittings that require heat fused socket connections. This material shall be included for repair and maintenance work.

Building 010A and Building 001 are examples where this material is part of existing systems.

The intent of the government is to have the contractor responsible for each system, starting immediately after the building water supply valve, up to and including the distribution valve after the system. The contractor shall be responsible for the following parts and equipment.
