66 -- DESIGN, ENGINEER AND DELIVER DISCHARGE MEASUREMENT RECORDERS SOL 1434-HQ-97-SS-00222 DUE 073197 POC Ms. Kathy Craig (703) 648-7357 (CO) See Numbered Notes 1, 12 and 26. The U.S. Geological Survey intends to issue a solicitation for a Fixed-Price Incentive (FPI) Indefinite Delivery-Indefinite Quantity (IDIQ) contract to design, engineer and deliver Discharge Measurement Recorders (DMR) to be used as part of the process to automate the stream gaging program of the Water Resources Division. The DMR will be a small, portable, battery powered instrument with data display which can be used by a hydrographer in a stream to measure and collect records of data from which the stream discharge can be determined using the mid-section method of computation. It shall guide the hydrographer through the process of data collection, accepting data entered by the hydrographer, measuring data directly from conventional vertical axis current meters, and calculating other relevant data. The data entry interface shall be optimized for a hydrographer wearing cold weather gloves. During the process of data collection, the DMR shall display key information and provide overall quality control. The DMR shall store records of data collected from several discharge measurements and serve as a vehicle for transporting and transferring it to a computer. It must operate properly when exposed indefinitely to temperatures ranging from -20 to 55 degrees Celsius, relative humidity of 10 to 100 percent, condensing, and rainfall or snowfall of light to moderate levels for at least two hours. Additionally, the DMR shall be capable of being exposed to temperatures of -40 to 60 degrees Celsius for indefinite periods, submergence in water to 1.524 meters (five feet) for at least 20 minutes, and daily exposure to direct sunlight for at least four hours without sustaining damage or having its operating characteristics permanently altered. The Government intends to issue a delivery order at contract award for five first article test units. After successful delivery of the five fully operational units, the Government shall purchase a minimum of 45 and a maximum of 145 additional units during the first performance year. At the option of the Government, the contract may be renewed for a second and third year with a minimum purchase of 25 units to a maximum purchase of 150 units for each additional year of the contract. The solicitation package shall be available approximately July 1, 1997 with closing 30 days after issuance of the package. Requests shall be in writing only (no telephone requests will be accepted). Requests can be submitted via facsimile at (703) 648-7901. It is the intent of the Contracting Officer to make the solicitation package available after July 1, 1997 via Internet at the following address: http://www.usgs.gov/contracts/index.html (0168)
