R -- FIXED PRICE CONTRACT FOR GAGE AND DISCHARGE MEASUREMENT SERVICES WITHIN ENGINEERING DIVISION SOL 003&&&-9710-0001 POC MR. JOHN BARNES, 601/631-5485 (Site Code CW38) Due 11-12-97, POC: John Barnes, 601/631-5485. 1. CONTRACT INFORMATION: Due by 11-12-97. One fixed price contract will be negotiated and awarded for a 24 month period. The contract is anticipated to be awarded in February 1998. The work will be accomplished within the Vicksburg District. 2. PROJECT INFORMATION: The work consists of taking a defined number of discharge measurements on a routine basis along the Mississippi River and tributaries. 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 flow measurements. The software (program code) currently in use in the Vicksburg District will be made available during advertisement. The work will also require collecting daily water stage data at over 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 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 verify his system by comparison with conventional discharge methods. All measurements will be in English units. 3. PRESELECTION CRITERIA: Pre-Selection criteria will be based on the following considerations which are of equal importance. The firm (either in-house or through association with a qualified consultant) must demonstrate: (a) experience in the use of ADCP systems on rivers such as the Mississippi, Red and Ouachita Rivers which have high sediment loads, extreme currents and variations in depths from 10 to 120 feet; (b) the ability to use the ADCP in conjunction with a single beam depth sounder and differential GPS to produce a single product discharge measurement; (c) experience in collecting discharge measurements by conventional methods; (d) a management plan for collecting, reporting, and storing river stage data; and (e) a registered land surveyor in either Arkansas, Mississippi or Louisiana. Deliverables shall be provided in the following format: hard copy, floppy disc, electronic transfer and/or on media approved by the contracting officer. Each discharge reading recorded will also record the corresponding date, mean gage reading (feet), maximum depth (feet), width (feet), cross-sectional area (square feet), mean velocity (feet/second), maximum velocity (feet/second), overbank discharge (cubic feet), total discharge (cubic feet) and water temperature (degree Fahrenheit). 4. SELECTION CRITERIA: See Note 24 of the CBD for the general selection process. The selection criteria are listed in descending order of importance (first by major criterion and then by each subcriterion). Criteria A through F are primary; criteria G through I are secondary and will only be used as a "tie-breaker" if necessary in ranking the most highly qualified firms. (A) Specialized experience and technical competence of the firm and consultants in the work described above in preselection items a, b and c. (B) Knowledge of the navigable rivers of the Vicksburg District. (C) Professional qualifications: The firm must document professional registration and work experience of key personnel. (D) Capacity: The firm should indicate the ability to perform on time regardless of unexpected equipment breakdowns and personnel problems. (E) Past performance: Consideration will be given to ratings on previous DOD contracts for engineering services. (F) Knowledge of the locality; specifically the drainage basins throughout the Vicksburg District. (G) Extent of participation of SB, SDB, historically black colleges and universities (HBCU) and minority institutions (MI) in the contract team. Participation will be measured as a percentage of the total anticipated contract effort, regardless of whether the SB, SDB, HBCU or MI is a prime contractor, subcontractor, or joint venture partner, the greater the participation, the greater the consideration. (H) Geographic proximity to Vicksburg, Mississippi. (I) DOD contract awards in the past 12 months. The greater the awards the lesser the consideration. In the final selection process, the most highly qualified firms will be interviewed and will have to demonstrate the ability to perform to satisfaction of the Vicksburg District. 5. SUBMISSION REQUIREMENTS: Interested firms must send one copy of SF 255 (11/92 edition) for the prime and consultants and one copy of SF 254 (11/92 edition) for the prime and one copy of each consultant's SF 254 (11/92 edition) to U. S. Army Engineer District, Vicksburg, ATTN: A-E Services (CEMVK-ED-AC) 4155 Clay Street, Vicksburg, Mississippi 39180-3435. All telephone calls should be directed to Mr. John Barnes, (601) 631-5485. This is not a Request for Proposal. A fee proposal will be requested at a later date. Along with the fee proposal, the selected firm (if a large business) will be required to submit a Subcontracting Plan in accordance with FAR 19.702 . . . etc., to Mrs. Shirley Reed, Small Business Specialist, (601) 631-5347.
