The purpose of this synopsis is to announce the U.S. Army Engineer District Chicago intent to award a Firm-Fixed-Price purchase order on a noncompetitive basis to Marcelo Garcia - University of Illinois (CAGE: 4B808) at 506 S Wright Street, Urbana, Illinois 61801-3620. This requirement is for the following: CLIN 0001 Grand Calumet River Bidirectional Flow Study Quantity: 1 Job Description: The services shall consist of updating the bathymetric and structure (i.e. bridges, culverts) data used in developing the geometry of the numerical model, developing a comparison between the original model bathymetry and USACE-provided datasets, extending the model�s boundary condition east to capture effluent flows from Gary Wastewater Treatment Plant, and to perform numerical simulations for a range of Lake Michigan levels to assess bidirectional flow characteristics of the Calumet Area Waterway subsystem. In addition, the Contractor will compare the model results against the regression equations currently used in the Chicago District diversion accounting computations and, using the updated model runs, develop revised regression equations for a wider range of Lake Michigan levels. The Government intends to negotiate solely with Marcelo Garcia under the authority of FAR 13.106-1(b), due to only one source being reasonably available to meet the Government's needs. FAR Part 12, Acquisition of Commercial Items and FAR Part 13, Simplified Acquisition Procedures, apply.

Interested parties may identify their interest and capabilities in response to this synopsis and must clearly show the firm's ability to be responsive without compromising the quality, accuracy, and reliability of services provided. A determination by the Government not to compete the proposed contract based upon responses to this notice is solely within the discretion of the Government.
