Professional Enhanced Commissioning Services – STATEMENT of WORK USGS NWHC modernization, Madison, WI - DRAFT

The U. S. Geological Survey (USGS) has a requirement for Professional Commissioning Services. The services provided shall include fundamental and enhanced commissioning services to further support the design, construction, and eventual operation of a project that meets the owner’s project requirements for energy, water, indoor environmental quality, and durability.

Services provided are for the modernization of the USGS’ National Wildlife Health Center (NWHC) in Madison, WI – further scope TBD.

BACKGROUND

National Wildlife Health Center (NWHC) The NWHC was established in 1975 to serve the nation and its natural resources by providing sound science and technical support regarding wildlife disease, and to disseminate information to promote science-based decisions affecting wildlife and ecosystem health. NWHC personnel study emerging and resurging diseases, wildlife and ecosystem health, zoonotic diseases, and environmental health and degradation. The NWHC is located on 24 acres and maintains offices and high security disease laboratories in the Main Building (MB) and the Tight Isolation Building (TIB).

This Statement of Work for Professional Commissioning Services is integral to the design and construction for the new facilities – further scope TBD.

O. FUNCTIONAL PERFORMANCE TESTING

a. Functional Performance Testing: Test procedures shall fully describe system configuration and steps required for each test; appropriately documented so that another party can repeat the tests with virtually identical results.

i. Test Methods; Functional performance testing and verification may be achieved by direct manipulation of system inputs (i.e. heating or cooling sensors), manipulation of system inputs with the building automation system (i.e. software override of sensor inputs), trend logs of system inputs and outputs using the building automation system, or short-term monitoring of system inputs and outputs using stand alone data loggers. A combination of methods may be required to completely test the complete sequence of operations. The Commissioning Agent shall determine which method, or combination, is most appropriate.

ii. Setup: Each test procedure shall be performed under conditions that simulate normal operating conditions as closely as possible. Where equipment requires integral safety devices to stop/prevent equipment operation unless minimum safety standards or conditions are met, functional performance test procedures shall demonstrate the actual performance of safety shut offs in a real or closely- simulated conditions of failure.

iii. Sampling: Multiple identical pieces of non-life-safety or non-critical equipment may be functionally tested using a sampling strategy. The sampling strategy shall be developed by the Commissioning Agent. If, after three attempts at testing the specified sample percentage, failures are still present, then all remaining units shall be tested at the contractors’ expense.

iv. Develop functional performance test procedures for equipment and systems. Identify specific test procedures and forms to verify and document proper operation of each piece of equipment and system. Coordinate test procedures with the contractor for feasibility, safety, equipment and warranty protection.

v. Functional performance test forms shall include the following information:

1. System and equipment or component name(s).

2. Equipment location and ID number.

3. Date.

iv. Once the interpretation and resolution have been decided, the appropriate party corrects the deficiency and notifies the Commissioning Agent that the equipment is ready to be retested.

v. The Commissioning Agent rescheduled the test and the test is repeated until satisfactory performance is achieved.

4. Cost of Retesting: Costs for retesting shall be charged to the Contractor.

R. OPERATIONS AND MAINTENANCE TRAINING

a. O&M Manual: Review the operation and maintenance manuals compiled by the contractor for completeness and for adherence to the requirements of the specifications.

i. Obtain additional materials from the contractor as necessary to stress and enhance the importance of system interactions, troubleshooting, and long-term preventative maintenance and operation.

b. Training: Develop a Training Plan. Coordinate and review the training programs for Owner’s personnel.
