FROM: David Townsend,Facilities Engineer Water Department DATE: February 26„ 1997 SUBJECT: PCM-024: South Holly Chlorine Piping Modifications' North and South Holly Water Treatment Plant Backwash Facilities Modification and Chlorine and Ammonia Rehabilitation Project Nos. PW77-060770500020&PW77-060770500030 This office has reviewed your correspondence dated February 25, 1997 on the proposed contract modification (PCM-024 ) concerning the replacement of the four 1-inch (2 per tank) chlorine fill lines from the South Holly WTP Fill Station to the South WTP Chlorine Tanks, with two 1-1/2-inch lines. After completion of the chorine system at the South Holly WTP, DPC (Chlorine Supplier) requested that the chlorine tank fill lines be 1-1/2" to facilitate the chlorine loading (or they would not load chlorine in the future). The Water Department agrees with your recommendation that the contractor's cost proposal of$17,183.31 for this item should be accepted as the cost provided is fair and reasonable. In addition, the Water Department accepts your recommendation that 15 additional days of contract time for final completion of the project be added to the contract. Therefore, this office will recommend to the City Council (and/or the City Manager's Office), the approval and acceptance of this additional cost in the form of a change order to be prepared and submitted by you to this office.

PW77-060770500020 & PW77-060770500030 This office has reviewed your correspondence dated January 21, 1997 on the proposed contract modification (PCM-027 ) concerning the modification of the return flow pump locations at the South Holly Water Treatment Plant Backwash Clarifier. The electrical plans and the mechanical plans where in conflict. As the electrical system was installed first, the mechanical (pump location) had to be modified. The contractor was directed to modify the pump location. The Water Department agrees with your recommendation that the contractor's "time & material" cost of$1,393.45 for this item should be accepted as the cost provided is fair and reasonable. Therefore, this office will recommend to the City Council (and/or the City Manager's Office), the approval and acceptance of this additional cost in the form of a change order to be prepared and submitted by you to this office.
