Box 478 Coppel 1 75019 Re ppel 1, Texas Dear Ken: Attached is a copy of a letter from Reed Engineering Group regarding the subgrade stabilization for the above project. Mr. Reed originally recommended two percent cement to be used in the stabilization process, however it is my understanding that the City desires at least four percent. I asked Mr. Reed to indicate the application rate to achieve four percent and as his letter indicates, this will require 18 pounds per square yard. Please accept this letter as a recommended change from lime treated subgrade to cement treated subgrade with four percent cement. A change order has been issued to the contractor and this change shall be reflected on the as built paving plans. Please respond to this change. If you have any questions m e copy: Mr. T~m House Matthews Southwes~%%%~ me in written with the City's approval of or comments, contact reed engineering 'I QEOTECHNIC~L GON~JLTAN'T~ October 8, xgg3 Pro,eot No. 1Z32.6 Matthews Investments Southwest 5220 spring valley Road, Suite 500 Dallas, Texas 75240 ATTN: Mr. Tim House Soil Stabilization Fountain Park Addition Sandy Lake Road Coppell, Texas Oentlemenl As you are aware, we recommended a minimum of two percent cement used in order to.stabilize the paving subgrade.
