E., Director Augusta-Richmond Utilities Department 360 Bay S1, Suite 180 Augusta, Ga. 30906 RE: Water filtration plant improvements - Additional Services (ZEL 9810) Dear Mr. Hicks: The construction work at the Water Treatment Plant has proceeded with a vast number of unforeseen conditions, which have required our involvement for resolution beyond the scope of Basic Services. These conditions have resulted in numerous change orders to the construction contract. Here is a listing of the items where we have provided engineering effort to enable the construction work: 1. Change Order No.1, attached, 7 items @ $215,655.30 in construction costs (attached). 2. Change Order No. 2, attached, l5 items @$138,783.51 in construction costs (attached). 3. Change Orders No. 3,4,and 5, attached, 3 items @ $1l,946in con$1;ruction costs (attached). 4. Change Orders No.6, and 7, attached, 6 items @ $140,298 in construction costs (attached). The total amount of additional construction costs is $506,682.81. The engineering fees for the original scope of this work computes to 6.7% of the original scope construction cost. We request compensation at that same rate of for our work in the additional items. The increase requested is $34,000, which will allow us to complete the project. Your consideration of our request is appreciated. Sincerely , VANS AND LEOPOLD, Inc. \ . , . . '----:.-~ _b~ ~"'-.., .

Box. 747 Pooler ,G.A 31322 Re:Underwaler Pipeline Inspection Mr.Wade Woodring 1b.is docwnent covers the findings from the September 13, 2000 ACMS dive inspectiun of a 30"pipeline and valve for Aqua South at the Augusta Ga. Potable water facilities eastern clearwelL The initial plan for the dive was to enler the 30" pipeline to determine whether or not the valve was operable or if it could be forced open. When we were called about this job we were infonned that the flow of the pipe would be minimal and that the flow direction would be against the diver such as a headwind, but this was not the case. After a quick review of the clearwell and the pipeline underwater I found that the Dow of the line was stronger than previously believed and that the flow was entering the pipeline instead of exiting. In an attempt to penetrate the pipeline I learned that the inside of the pipe was covered with a very slick algae like substance which would make it virtually impossible (or me to push myself backward out of the pipe ifa problem should occur. I came to the conclusion that the dive was unsafe under these conditions was consequently not feasible. After the dive was aborted, the workers on site were directed to open and close the valve repeatedly to try and break it free so that it could close completely. The valve was opened and closed several times until we felt that it bad broken free, and was closable, The valve was put into the closed position, and another dive was done, to determine if the flow had stopped. There was no perceivable flow going or coming from the pipeline. We were then asked ifwe could go into the pipeline and check the valve, to make sure it had closed completely. This was considered not feasible for diver safety reasons. There was no way to determine if the valve in question was under differential pressures((this is one of the leading causes of fatal accidents in the commercial dive industry) see ADC video included in the correspondence]. Everyone on site agreed that it was likely that there was a 90 degree turn in the pipe between the entry point and the valve in question, and this posed another potential diver hazard.
