.:,. TO: FROM: e e ~::.....: INTER-OFFICE MEMORANDUM SEPTEMBER 7, 1983 J. Engineer J. Ra SUBJECT: Sealed B 10017: Nuclear Moisture Density Gauge Advertised sealed bids 10017 for the purchase of a "Nuclear Moisture Density Gauge" were opened and read aloud in Council Chambers September 7, 1983 at 4 P.M. The gauge will be used to simultaneously and accurately. measure den- sities and moisture content of fills, embankments, bases, sub-grades, and as- phaltic concrete by the Engineering Dept. In the past, such tests were done manually by outside firms at great cost and extensive delays. Nuclear density gauges provide non-destructive, statistical testing with speed and accuracy. A survey was taken of agency users of Nuclear Moisture Density Gauges including; (1) Texas Highway Dept., (2) U.S. Corps of Engineers, (3) Texas A&M University, (4) Trinity Engineering and Testing, and (5) Brown & Root, Inc. Information received from these agencies indicated that there were only two competitive units on the market which would fit the City of La Portes' applications. Bids were then obtained from both Component Sales & Service Inc. which sells the CPN Model MC-2 and from Troxler Electrical which sells the Troxler Model #3411B. Both units are very comparable to each other and meet all specifications set out by the Engineering Dept. I therefore recommend accepting the low bid by Troxler Electronics on their Model #3411B in the amount of $4,265.00. I trust this recommendation will meet with your approval. JR/mb cc: B.
