Mr. Bob Lawson <br /> December 4 , 2008 <br /> Page 2 <br /> 4 . We added an irrigation system to the odor control mulch pit in order to keep it moist. <br /> This included modifying the water system , design of the irrigation system , and <br /> adding electrical power for the solenoid and the time clock . <br /> 5 . Eckler Engineering had to redesign the vacuum main along the east side of 14"' <br /> Street due to unknown existing utilities along the west side of the street where the <br /> pipeline was originally designed . <br /> 6 . Eckler Engineering investigated the extension of the vacuum collection system on <br /> 160' Street to serve the existing car wash and warehouse . This was in an effort to <br /> eliminate the private wastewater pump station serving these businesses . This <br /> warehouse and car wash were outside of the original limits of the project and had <br /> not been included in the original design . As it turned out, the cost of connecting <br /> these two facilities was more than the owner's were willing to pay and they were <br /> consequently not connected to the system . This investigation involved obtaining <br /> water consumption data , time of day water usage data , and peak water demand <br /> information . Once this information was known , then we could design the <br /> modifications to the existing system . <br /> 7 . There were two houses and two condominium buildings outside of the original <br /> service area which required service . Eckler Engineering designed the vacuum <br /> main , service lines and vacuum pits to serve these new connections . <br /> Eckler Engineering has spent nearly $ 18 , 000 completing these items outside of the original scope . <br /> We do know that there will be some additional coordination required to finalize the operation of the <br /> SCADA system between Airvac, DATAFLOW , and the County. Eckler Engineering requests an <br /> addition to our contract of $ 18,000 which will be billed on an hourly rate plus direct expenses basis . <br /> Please review this request and forward to Mr. Larry Brown as soon as possible before his time on <br /> this project runs out. If you have any questions or require additional information pertaining to this <br /> request or the project in general , please do not hesitate to contact me . <br /> Sincerely, <br /> Donald A.
