Specifications include, but are not limited to: This work supports the implementation of the AirCheckTexas Vehicle Emissions I/M program. The current versions of software on the Worldwideanalyzers are proprietary and licensed for the sole use of the Worldwide-manufactured analyzer on which it resides. Modifications can only be performed by the manufacturer who produced the analyzer. Under this procurement, Worldwide agrees to provide any necessary software update services to its emissions analyzers to accommodate current and future I/M program changes. Any future changes will be specified, in writing, through amendments issued by TCEQ. When future contract amendments are issued, Worldwide will be required to make changes to the software as necessary, conduct internal testing to ensure that the software functions properly, submit the software for certification testing, install the software in the analyzer for beta testing, and successfully install the software in the fleet of Worldwideanalyzers operating in the Austin-Round Rock, El Paso, Houston-Galveston-Brazoria, and Dallas-Fort Worth areas and other counties that may be identified at no cost to the vehicle emissions inspection stations.
