Terracon Project No. 20165085
Dear Mr. Nolen:
Previously, Terracon Consultants, Inc. (Terracon) prepared a Geotechnical Engineering Report
(Project No. 20165085; report dated October 19, 2016) for the project referenced above. The
water-soluble sulfate testing was not complete at the time the report was prepared. This
supplemental letter presents the results of the water-soluble sulfate testing performed for the on-
site soils.
Results of water-soluble sulfate testing indicate that ASTM Type I or II portland cement should be
specified for all project concrete on and below grade. Foundation concrete should be designed
for low sulfate exposure in accordance with the provisions of the ACI Design Manual, Section
318, Chapter 4. Test results also indicate chemical treatment of the subgrade soils with fly ash
can be completed using a conventional single application.
The recommendations presented in this report should be used in conjunction with those presented
in our initial Geotechnical Engineering Report for the project. The General Conditions should be
reviewed and understood to apply to those engineering recommendations and opinions presented
herein.
