59 -- TEMPERATURE MONITORING SYSTEM FOR HYDROELECTRIC FACILITIES LOCATED AT HYDROPOWER SECTION, ELBERTON, GA SOL DACW21-97-Q-0113 DUE 081497 POC Edwina S. Frayall, Purchasing Agent, (912) 652-5987, or Alice N. Hicks, Contracting Officer WEB: Corps of Engineers, Savannah District, Contracting, http://www.sas.usace.army.mil/ct/index.html. E-MAIL: Edwina S. Frayall, edwina.s.frayall@sas02.usace.army.mil. This project requires the contractor to provide delivery and on-site installation for an upgraded Temperature Monitoring System (TMS) to enhance the existing system which is comprised of the following: 2 Leeds and Northrup (L&N) Micromax I Management Stations, 1 L&N Micromax II Management Station, 17 independently operating local processing units (LPUs) and 3 spare local processing units. The upgraded TMS will comprise of the following: Replace the existing Management Stations with three new independently operating Management Stations. As a minimum, these new stations shall: (a.) operate on 120 VAC 60 Hz power and have a backup power supply which will allow operation for a minimum of two hours without normally supplied electrical power, (b.) have 200 MHZ Pentium processors, 32 MB RAM, 3.0 MB GB Hard Drive, 1 GB internal removable hard drive (cartridge) backup, 3 1/2 disk drive and RS 422/485 communications port, (c.) interface with the LPUs via the RS 422/485 communications port at distances ofup to 1000 feet, various printers via a bi-directional parallel port, and the plant's event recorder. As a minimum, the Management Station software shall: (a.) be capable of developing programming for and individually programming the LPUs via the RS 422/485 communications port, (b.) be capable of checking the programming installed to each LPU via the RS 422/485 communications port, (c.) be capable of storing data received over a period of two days, (d.) provide for graphical analysis of temperature versus time for each data point, a selected group of points, average temp versus time, etc., Upgrade the LPUs, as a minimum, the improved system shall: (a.) operate on 120 VAC 60 Hz power, (b.) operate satisfactorily between 32 F and 120 F and humidity levels up to 100%, (c.) be capable of operating independently of the Management System or any other parallel LPU, (d.) be capable of storing data received during a 24-hour period, (e.) be capable of monitoring either 10 Ohm Copper, 100 Ohm Platinum or 1000 Ohm Platinum RTDs with only minor hardware and/or programming changes. (f.) provide output for and interface with the Management System via a RS 422/485 communications port, (g.) provide output for and interface with the plant's general alarm panel, (h.) provide at least 10 discrete outputs handling 129 VDC, (i.) upon completion of modifications, all enclosures and connections will be drip proof with reusable gaskets/lids/covers. Set-aside type: This is an unrestricted procurement. The standard industrial classification code (SIC) is 3823, and size standard is 500. Closing date for receipt of quotations will be specified in the quote when it is issued. Request for solicitation packages must be submitted in writing via mail or fax (912) 652-5828. Telephone requests will not be honored. The anticipated RFQ release date will be on or about August 15, 1997. (0210)
