2.  PROJECT INFORMATION:  The work consists of providing professional services as required in connection with Automated Hydrographic Surveying, including both single-beam and multi-beam methods, and Automated Topographic Surveying in support of the Vicksburg District Maintenance Dredging and Mat Sinking Operations at various locations primarily within the limits of the Vicksburg District but may include any district within MVD.  Automated Real-Time Kinematic (RTK) Differential GPS Hydrographic Surveys and Automated Topographic Surveys will be required on the Mississippi River, its tributaries, and smaller rivers and streams and associated harbors. 

ADCP Surveys for the acquisition of river current and discharge data may be required for acquisition of current and flow patterns at locks and dams, around dikes, bridge piers or obstructions in channels.  The work consists of taking a defined number of discharge measurements on a routine basis along the Mississippi, Red, and Ouachita Rivers. The measurements will be taken with the use of an Acoustic Doppler Current Profiler (ADCP) and a single beam depth sounder. The data collected will be imported into personal computer software specifically designed to calculate and view flow measurements. The Proposal shall include the Contractor’s software(s) to be employed under this solicitation if selected.  The work will also require collecting daily water stage data at approximately 50 gaging sites throughout the Vicksburg District and reporting information daily and monthly to the Vicksburg District. Additional work will consist of maintenance of permanent reference elevation markers at each gaging site and infrequent collection of suspended sediment samples at specific discharge ranges. Extreme flow conditions may require a combination of the ADCP, a single beam depth sounder, and differential GPS. The contractor may be required to take special purpose flow pattern and discharge measurements at lock and dam locations. The contractor may be required to verify his system by comparison with conventional discharge methods. All measurements will be in English units.

3.  SELECTION CRITERIA:   Selection will be based on the following
