B--Notice of intent to award a sole source contract for the calibration/validation and maintenance of the ELCOM/CAEDYM model for Lake Mead.

The National Park Service at Lake Mead National Recreation Area plans to award a sole source contract to Flow Science Incorporated for the calibration, validation, and ongoing maintenance of the ELCOM/CAEDYM water quality predictive computer model specifically designed for Lake Mead. This comprehensive model will cover all major basins within the lake, including Boulder Basin, Overton Arm, Virgin Basin, and Gregg Basin. Its purpose is to assist an interagency team responsible for water quality and water management in assessing the potential environmental impacts stemming from various water usage scenarios and community developments that affect the lake's tributaries. The contract falls under the NAICS code 541330 with a size standard between $5 million and $10 million. Although this notice signifies the intent to award a sole source contract, it is not a solicitation for competitive proposals. However, interested parties with the capacity to fulfill the requirement are invited to express their interest or submit proposals by March 1, 2008. The point of contact for this acquisition is Judith C. Couch, a contract specialist at the Department of the Interior, who can be reached via email. The work is managed through the Dsc Contracting Services Division based in Denver, Colorado.
