RE:
6.0 MG Groundwater Storage Tank
Coppell, Texas
Dear Mr. Barbarisi:
The purpose of this letter is to confirn~ verbally authorized services by site superintendent, Mr.
Jim Fisher of Natgun Corporation at the aforementioned project.
On December 28, 1995, in a telephone conversation with the undersigned, you requested we
cast three additional cylinders from a wall panel and three cylinders from a dome panel on the
first day of on-site panel construction, in addition to test cylinders that were to be fabricated
for the City of Coppell. I gave you the cost for additional cylinders without the need for a
second technician to cast such on site.
On December29, 1995, on site, Mr. Fisher wanted our on.-site field technician to check slump,
.air cont,~t~ t~,nne~ratUr,~ an,t .fabricate one ~,'~ of three ,-,,lindor~ from every Redi-Mix track
used to cast pauels. In addition, Mr. Fisher requested we complete Natgun's Concrete Quality
Control Data sheets on site.
Based on our proposal to the City of Coppell, we were to perform reinforcing steel inspections
of all panels and were to cast one set of three cylinders per 100 cubic yards concrete per day.
We informed Mr. Fisher that casting one set of three cylinders, rumring slump, air, and
temperature tests from every truck as well as completing Natgun's concrete quality control data
sheets would require a second technician on site, costs for which were not included in our
proposal to the City of Coppell. We informed Mr. Fisher that the additional requested second
technician and casting of cylinders fi'o~n every truck were for the convenience and use of
Natgun Corporation, and the additional time for a second technician as well as extra cylinders
would have to be paid for by Natgun Corporation. Mr. Fisher told us that he could not get
Mr. Bob Barbarisi, Natgt .'cration June 3, 1996
i'n touch with you and confirm this matter, however, he approved a second technician to
fabricate additional cylinders for December 29, 1995. The subject of paying for the additional
technician and cylinders was again put to Mr. Fisher on January 2, 1996, and he again told us
he had not talked with you.
When we again spoke with Mr. Fisher on January 3, 1996, he informed us that he had spoken
with you, and Natgun Corporation agreed to pay for the additional technician and cylinders.
Please call if you have any questions.
