WASHINGTON AQUEDUCT DIVISION
Technical Support and Maintenance Services for: Laboratory Reverse Osmosis / Deionized
Water System
Michael Chicoine (202-587-9139) michael.l.chicoine@usace.army.mil
W912DR22Q0074
1. Introduction: The Washington Aqueduct (WA), a division of the Baltimore District United States Army Corps of Engineers, p roduces drinking water for over one million citizens living, working, and visiting in the District of Columbia, Arlington County, Virginia, and the City of Falls Church, Virginia, and its service area.
WA has the responsibility to provide safe, reliable, cost-effective drinking water 24 hours a day, seven days a week. The Aqueduct is a federally-owned and operated public water supply agency that produces an average of 180 million gallons of water per day at two treatment plants located in the District of Columbia. All funding for operations, maintenance, and capital improvements comes from revenue generated by selling drinking water to the three jurisdictions.
The Washington Aqueduct (WA) is a critical infrastructure that operates two water treatment plants (WTPs), the Dalecarlia WTP and the McMillan WTP. Located at the Dalecarlia WTP is the WA Laboratory. The primary mission of the WA Laboratory is to provide quality analytical support services to the Washington Aqueduct and its wholesale customers in order to ensure the safety and quality of the drinking water. As a service, the WA Laboratory performs legally-required drinking water compliance testing in accordance with local, state, and federal statutes. Extensive testing includes various chemical, biological, radiological, and other required parameters. The Washington Aqueduct Laboratory routinely analyzes process control, customer compliance, and research water samples. Occasionally, emergency water sample testing is required. In accordance with its mission, the Washington Aqueduct Laboratory is required to maintain a continuous state of readiness for water sample analysis.
The Laboratory’s Deionized Water System equipment included in this performance work statement (PWS) is used for providing contaminant-free water (Type I Reagent Grade Water, at a minimum) that is used for sample collection and laboratory testing. Testing at the water quality laboratory and the operator laboratories employs methods for microbiology, metals, organic, and inorganic compounds, which require reagent water. The reagent-grade water is also used for microbiological media preparation and for rinsing glassware. Since all of these procedures require reagent-grade water, Washington Aqueduct is required to maintain a continuous readiness status regarding the quality and supply of reagent-grade water to ensure analytical readiness.
2. Background: The contractor shall independently provide support services to satisfy the overall operational objectives of the Washington Aqueduct. The primary objective is to provide contractor services and deliverables through performance of technical support and routine on-site maintenance support. The services rendered shall be for the contractor to provide on-call and on-site assistance in areas pertaining to the Deionized Water System operation, troubleshooting, and maintenance.
3. General Requirements

Annual Support and Service Contract: Laboratory Reverse Osmosis / Deionized Water System
Contract Description: The U.S. Army Corps of Engineers, Baltimore District proposes to procure a contract to provide the technical support and maintenance of one Reverse Osmosis / Deionized Water System located at the Washington Aqueduct Laboratory. Maintenance will be performed as scheduled in the service contract or when requested by the Washington Aqueduct Laboratory Section.
Contractor’s name: TBD
1. PURPOSE
This Quality Assurance Surveillance Plan (QASP) provides a systematic method to evaluate performance for the stated contract. This QASP explains the following:
Confirm that the action is conducted utilizing proper procedures and in accordance with the approved work and safety plans.
Define the roles and responsibilities of participating Government officials.
Define the types of work to be performed with required end results.
Document the evaluation methods that will be employed by the Government in assessing the Contractor’s performance.
Provide the Surveillance Activities Table and Corrective Action Request (CAR) form that will be used by the Government in documenting and evaluating the Contractor’s performance.
Describe the process of performance documentation.
This QASP does not detail how the contractor accomplishes the work. Rather, the QASP is created with the premise that the contractor is responsible for management and quality control actions to meet the terms of the contract. It is the Government’s responsibility to be objective, fair, and consistent in evaluating performance. In addition, the QASP should recognize that unforeseen and uncontrollable situations may occur.
This QASP is a “living document” and the Government may review and revise it on a regular basis. However, the Government shall coordinate changes with the contractor. Updates shall ensure that the QASP remains a valid, useful, and enforceable document. Copies of the original QASP and revisions shall be provided to the contractor and Government officials implementing surveillance activities.

The contractor is required to submit a service report documenting all installed parts and repairs provided per on-site visit. The government will analyze the contractor's service reports with regards to the status of each service request.
6. RATINGS
Metrics and methods are designed to determine if performance exceeds, meets, or does not meet a given standard and acceptable quality level. A rating scale shall be used to determine a high to low, or neutral outcome. The following ratings shall be used:
HIGH:
Accurate technical support is provided at the time of inquiry. System repairs are scheduled and completed with no disruption to sample monitoring and analytical testing schedules. Contractors submit documentation of work completed immediately following on-site visits.
MODERATE:
Accurate technical support is provided at the time of inquiry or within one work day. System repairs are scheduled and completed with minor disruptions to sample monitoring and analytical testing schedules.
Contractors submit documentation within one week of work completed on-site.
LOW:
Inaccurate technical support is provided at the time of inquiry. System repairs are delayed and completed with significant disruptions to sample monitoring and analytical testing schedules. Contractors do not submit documentation of work completed on-site.
NEUTRAL: Unable to provide an evaluation.
7. DOCUMENTING PERFORMANCE

The Government shall retain completed contractor service reports to document positive performance.
b. UNACCEPTABLE PERFORMANCE.
Unacceptable performance is defined as the unavailability of technical support, no response to service requests, incomplete work, unavailability of parts, and/or not providing a written service report. Should routine unacceptable performance occur, the COR shall inform the contractor. This will normally be in writing unless circumstances necessitate verbal communication. In any case the COR shall document the discussion and place it in the COR file.
When the COR determines formal written communication is required, the COR shall prepare a Contract Discrepancy Report (CDR), and present it to the contractor's task manager or on-site representative. A CDR template is attached to this QASP.
The contractor shall acknowledge receipt of the CDR in writing. The CDR will specify if the contractor is required to prepare a corrective action plan to document how the contractor shall correct the unacceptable performance and avoid a recurrence. The CDR will also state how long after receipt the contractor has to present this corrective action plan to the COR. The Government shall review the contractor's corrective action plan to determine acceptability.
Any CDRs may become a part of the supporting documentation for contract payment deductions, fixed fee deductions, award fee nonpayment, or other actions deemed necessary by the KO.
8. FREQUENCY OF MEASUREMENT
During contract/order performance, the COR will take measurements of the contractor’s performance per on-site visit including documented service requests and annual preventative maintenance.
