PW77-060770500020 & PW77-060770500030 This office has reviewed your correspondence dated August 16 1996 on the proposed contract modification (PCM-003) concerning the installation of a potable water line around the northwest corner of the SIIWTP Chlorine/Ammonia storage area. This line would provide a alternate (back-up) water feed to the chlorine & ammonia scrubbers. Also, a 6-inch gate valve was installed on the water feed to the SHWTP Chemical Building to allow isolation for operation and maintenance purposes. The Water Department agrees with your recommendation that the contractor price proposal of $1,355.65 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. For accounting purposes, this PCM will be paid 100% from PW77-060770500030. cti David R< �rc Pd✓. - cc: Frank Crumb Files FreesA C Simon Freese,P.E. 1900.1990 �+ Marvin C.Nichols,P.E. 1896-1%9 AND Nichols,INC.

PW77-060770500020 & PW77-060770500030 This office has reviewed your correspondence dated March 1J, 1996 on the proposed contract modification (PCM-006 ) concerning the installation of 4 access hatches each for both the North & South holly Chlorine Buildings. The ceiling does not allow access to the HVAC or other utilities above the ceiling. As some walls extent to the roof, and access to entire "attic" is limited by the I1VAC, four hatches are required at each building. The Water Department agrees with your recommendation that the contractor price proposal of$1,21625 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.
