66 -- MEASUREMENT AND THERMAL EVALUATION TEST DATA MGMT SYSTEM SOL DACW39-97-Q-0015 DUE 122396 POC Mallorie O. Irwin, Purchasing Agent, (601)634-4116 WEB: Contracting Division Homepage, http://www.wes.army.mil/contract.htm. E-MAIL: Mallorie O. Irwin, irwin@ex1.wes.army.mil. The USAE Waterways Experiment Station (WES) proposes to award a purchase order to Digital Site Systems, Pittsburg, PA under authority 10 U.S.C.2304(c)(1) for the purpose of a temperature, maturity, and heat of hydration measurement and computerized thermal evaluation/test data management system for concrete. The system must be commercially available. The system must include integrated, computerized test equipment for determination of concrete adiabatic temperature rise, maturity, and heat of hydration; and include seamless integration to networked software for temperature rise and heat of hydration analysis, simulation analysis for in-place temperature, maturity, and strength through heat transfer and maturity modeling, and an integrated database with data management for concrete mixture design, and test data management and evaluation capabilities. The test equipment must include heat of hydration calorimetry for cement paste/mortar/concrete cylindrical samples sizes of 2"x4", 6"x12", and 9"or 12"x16" through precision measurement of temperature and thermal energy loss recorded by compatible, high-precision, 16-bit data loggers. The data loggers shall have dynamic full-scale range with 1 micro-volt resolution, programmable for interface to the calorimeters, or to other temperature and maturity measurements. The battery-operated units must be capable of stand-alone operation, provide user-defined data scan intervals, and be enclosed in weather-resistant housings. The units must also include a portable module for programming and monitoring as an alternative to using a PC with compatible software. The software must be compatible with Windows 3.1, 95 and NT; operable on Novell or NT networks; and include an SQL database engine with ODBC or native drivers for Oracle or other major database products. The relational database must be structured to handle a variety of tests, unlimited number of concrete mixtures and ingredients, mixture economics, and a range of other database variables. The system must allow various views of the database including hierarchical, user-defined, and data logger tests; simultaneous, multiple views of the database with object-oriented graphing, overlays, and drag and drop capabilities. Retrieved data must be relationally linked to user-selected test batches and specific calorimeters with measured calibration factors. Data entry of adiabatic temperature data from other test sources along with provision for computation of non-linear specific heat is required. Automatic analysis of heat of hydration data must include provision for non-linear specific hea of concrete and consideration of thermal capacity of the calorimeter with cumulative and rates of adiabatic heat and temperature rise data displayed graphically and saved as spreadsheet files. Basic data management must include laboratory and field data entry forms for plastic properties and hardened properties for cylinders, cubes, prisms, and beams. The software must include a laboratory test scheduler to provide data entry forms for the day of test, provide automatic compilation of measured data, and generate automatic test reports. Te software must include mixture design functions to generate concrete mixture proportions using reference mixtures through user selection or via database search using matching criteria. It must provide dynamic reference mixture designation through drag and drop menus, a catalog of mixture designs, and a mixture design submittal engine allowing mixture adjustment via user-specified criteria. Required delivery time is 60 days after receipt of award. In the event no other sources are found, the U.S. Government intends to award a contract to Digital Site Systems. Solicitation documents are not available. Any inquiries should be received within 15 days from the date of publication of this notice. (0341)
