In accordance with FAR Part 13 and FAR Part 12, the EPA's National Vehicle and Fuel Emissions Laboratory (Ann Arbor, Michigan) will procure a Tier 2 Sampling, Measurement, and Control Systems. As part of the Clean Air Act and its Amendments, a variety of new emissions regulations have been implemented for vehicles and engines. Tier 2, NMOG, SULEV, OBD II on-board diagnostics, and Supplemental FTP are a few examples of test changes that require sophisticated and adaptable emission measurement systems. The EPA NVFEL has undertaken a comprehensive program to implement new and refined test systems to enhance the capabilities to conduct low level emissions testing, of the highest precision and accuracy, on a broad range of vehicles. The Statement of Work (SOW) describes the engineering and operational requirements for measurement systems that will be required for implementing these enhanced capabilities. The equipment implementation described in the SOW is comprised of two complete measurement systems for two separate chassis test sites at the NVFEL, D329 and D005, and a partial upgrade of the existing measurement system for a third chassis test site, D002. These measurement systems shall be used to evaluate both regulated emissions and currently unregulated emissions from spark ignition motor vehicles operating in a variety of ambient conditions and on a variety of fuels including those currently considered as "alternative". The SOW addresses requirements to optimize the measurement of emissions at Tier 2 levels. For the equipment specified, the contractor shall have total system responsibility, which shall include all phases of the project, design, configuration, fabrication, assembly, integration, quality assurance, delivery to EPA-NVFEL, installation, calibration, commissioning, acceptance testing, documentation and training of EPA staff. The contractor shall be responsible for documenting measurement traceability and system acceptance in a manner suitable for audit to ISO standards. D329 Light/Medium Duty, FWD/RWD/4WD Test Site Overview This will be a new test site at NVFEL, intended to provide a wide range of test capabilities. It will house a medium duty / 4 wheel drive dynamometer intended to test a wide range of vehicles with from 1000 to 14,000 pounds of simulated inertia per roll set, with single or dual drive axles, fueled by gasoline, oxygenated fuels, alcohol fuels, gaseous fuels and diesel or other high-cetane fuels. The measurement system shall support protocols such as Tier2 level FTP, US06, HFET and others. The core requirement of this contract shall be to configure, build and implement a complete sampling and measurement system for this test site. This system shall provide for test sequencing and control, exhaust sampling and analysis, data acquisition and data analysis, processing and file transfer, along with a variety of tools for maintenance calibration and support activities. The system shall provide both CFV-CVS and Exhaust Flow Measurement System (EFMS) Bag Mini-Diluter (BMD) sampling for regulated gaseous emissions, as well as aldehyde and particulate sampling for all fuels, and alcohol sampling via impinger. The associated analytical system shall provide for direct on-site analysis of Carbon Monoxide, Carbon Dioxide, Oxygen, Hydrocarbon, Methane, Oxides of Nitrogen (NOx), Methanol, Ethanol and Formaldehyde. The dynamometer and video driver's aide equipment for this will be provided by others, but integration with these subsystems shall be included as part of the work described in the SOW. Dynamometer and Driver's Aide interface requirements are outlined in Appendices to the SOW. The contractor shall deliver a system capable of the measurement, calculation, and reporting of the mass emissions from motor vehicles in accordance with the emissions standards and regulations referenced in the SOW. The system shall provide the necessary software to calculate the emissions from both the CVS and EFMS/BMD systems. This procurement will include two options. D005 Light Duty Test Site (OPTION 1) This test site houses an existing 48" roll electric dynamometer and older test control, data acquisition and sampling and analytical systems. The contractor shall provide a sampling and measurement system to replace the existing cell control, data acquisition and sampling and analytical systems at this site. This site shall be used to test light duty cars and trucks at the lowest levels of Tier 2 fueled by gasoline and similar fuels. The existing dynamometer and EPA video driver's aide shall be utilized. This measurement system will not include requirements to sample and measure particulate matter, oxygenates, aldehyde or alcohol. D002 Light Duty Test Site (OPTION 2) This site houses an existing 48 inch roll electric dynamometer as well as a low level emissions measurement system described in the SOW. This measurement system is approximately two (2) years old and contains many of the features required for the D005 system described above, with the exception of the EFMS/BMD. The contractor shall provide for the full integration of a bag mini-diluter sampling system, as provided in the D005 system, with the existing D002 measurement system. This procurement will be made using "Best Value" evaluation criteria and Full and Open Competition for everything in the SOW including Options. The solicitation should be issued by March 5, 2003 on our website. A "DRAFT" of the proposed Statement of Work for this requirement can be found at http://www.epa.gov/oam/cinn_cmd. Interested parties are invited to review the "DRAFT" SOW and provide any comments by February 28, 2003 via fax to Scott Tharp (513) 487-2107 or email at
