The Plant staff has requested that a remote signal to SCADA be installed to identify which eyewash was activated for emergency response purposes. The contractor has provided a price proposal of$3,921.20 for this work. CMR-015A: SOUTH HOLLY WTP BASIN FLOODING EVENTS--------------------------------------------------------------------------------------------$ 6,082.60 The contractor has requested compensation for the flooding events at the South Holly WTP basins on July 9, 1996 and August 26, 1996. On these occasions, the filter backwash equipment failed to operate properly causing the backwash gallery to overflow into the contractor's construction area washing out the backfill around the 48-inch pipeline(to the new clarifier) and flooding the partially constructed backwash clarifier. The contractor incurred extra expense to dewater and cleanup the backwash clarifier along with replacing backfill on the 48-inch pipeline. CMR-017:SOUTH HOLLY WTP TRANSFORMERS TEMPERATURE RATING CREDIT -------------------------------------------------------------$(1,683.00) The Contractor will provide a credit of $1,683.00 for the South Holly WTP Transformers T5 & T6 not having the specified temperature rating. The specifications require this size (500 KVA) transformer operate at their design load without increasing temperature above 55 degrees C. The subject transformers had a temperature rise of 56.9 and 59.0 degrees at their design loads.The transformers as installed should perform adequately despite their failure to comply with the temperature rating portion of the specifications. CMR-018:CHLORINE AND AMMONIA LEAK ZONES ------------------------------------------------------------------------------------------------------$ 5,776.06 The contractor shall install additional chlorine and ammonia leak detection zones at the North and South Holly Chlorine Buildings. The contract documents call for three chlorine leak detection zones or areas(rooms)and three ammonia leak detection zones per plant. For safety reasons,the plant requested that leak detection zones in the chlorine building be broken into room zones to determine which room the"leak"is in without entering the building. This increased the leak detection zones to six chlorine and four ammonia leak detection zones. The detection equipment is already part of the contract, the additional work is instrumentation/control modification.The Contractor has provided a price proposal of$5,776.06 for this work. THE TOTAL COST FOR CHANGE ORDER NUMBER#5 IS $ 14,096.86 It is understood and agreed that the acceptance of this Change Order by the contractor constitutes an accord and satisfaction and represents payment in full(both in time and money)for all costs arising out of,or incidental to,the Change Order.

PW77-060770500020 & PW77-060770500030 This office has reviewed your correspondence dated October 10, 1996 on the contractor's modification request (CMR-015A) concerning the flooding events at the South Holly Water Treatment basins on July 9, 1996 and August 26, 1996. On these occasions, the filter backwash equipment failed to operate properly causing the back,vash gallery to overflow. The water then overflowed into the contractor's construction area washing out the backfill around the 48-inch pipeline (to the new clarifier) and flooding the partially, constructed backwash clarifier. The contractor incurred extra expense to dewater and cleanup the backwash clarifier along with rebackfill the 48-inch pipeline. The Water Department agrees with your recommendation that the Contractor's costs of$6,082.60 is fair and reasonable. This office will recommend to the City Council (and/or the City Manager's Office), the approval and acceptance of this cost in the form of a change order to be prepared and sub it .d by to this office.

PW77-060770500020 & PW77-060770500030 This office has reviewed your correspondence dated October 9, 1996 on the contractor's modification request (CMR-017) concerning the credit for the South Holly Nater Treatment Plant Transformers T5 & T6 not having the specified temperature rating. The specifications require this size (500 KVA) transformer operate at their design load without increasing temperature above 55 degrees C. The subject transformers had a temperature rise of 56.9 and 59.0 degrees at their design loads. A determination has been made that the transformers as constructed should perform adequately despite their failure to comply with the temperature rating portion of the specifications. The plant having no objection, the Water Department agrees with your recommendation that the City should accept a credit of $1,683.00 for transformers not meeting the temperature rating portion of the specifications. This office will recommend to the City Council (and/or the Cit)' Manager's Office), the approval and acceptance of this credit in the form of a change order to be prepared and s omitted by you to this office. 1 DavLR. wnsend, '.E. cc: Frank Crumb Fibs Freese Simon W.Freese,P.E. 1900.1990 Marvin C.Nichols,P.E. 1896-1%9 AND C Nie ols,INC.

Specification 16162.2.03.A for the Chlorine and Ammonia Facilities Rehabilitation requires the 500 KVA transformers l)e able to operate at their design load conditions without exceeding a 55 degree C temperature rise at the specified insulation level. The subject transformers had heat rises of approximately 56.9 and 59.0 degrees at design load Conditions. A review of the expected electrical loads and the resulting heat rise of the transformers as constructed was performed and it was recommended that the City accept the transformers if an appropriate credit was provided for the variance from the specified heat rise. The transformers as constructed should perform adequately despite their failure to comply with this portion of the specifications. We had reviewed Cajui s price proposal and recommend the City accept the proposed deductive credit of$1,683.00.

INTER-OFFICE CORRESPONDENCE TO: Ted Gay, Freese &Nichols, Inc. . FROM: David Townsend, Facilities Engineer Water Department DATE: December 6, 1996 SUBJECT: CMR-018: Chlorine and Ammonia Leak Zones 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 December 3, 1996 on the contractor's modification request (CMR-018) concerning the additional chlorine and ammonia leak detection zones at the North and South Holly Chlorine Buildings. The contract documents call for three chlorine leak detection zones or areas (rooms) and three ammonia leak detection zones per plant. For safety reasons, the plant requested that leak detection zones in the chlorine building be broken into room zones to determine which room the "leak" is in without entering the building. This increased the leak detection zones to six chlorine and four ammonia leak detection zones. The detection equipment is already part of the contract, the additional work is instrumentation/control modification. The Water Department agrees with your recommendation that the City should accept the contractor price proposal of$5,776.06 should be accepted as the cost provided is fair and reasonable. This office will recommend to the City Council (and/or the City Manager's Office), the approval and acceptance of this credit 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 from P%k'77-060770500030. QR. Townsend, P.E. cc: Frank Crumb Files December 3,1996 Mr. David Townsend,P.E.

This CMR" requests additional compensation for additional chlorine and ammonia leak detection zoning. To provide better protection in case of a chlorine or ammonia leak, the plant requested that the three chlorine and three ammonia leak detection zones required by the Contract Documents be modified to I,e six chlorine and four ammonia zones. Due to the duplicity between the South and North Chlorine Projects, it was negotiated with Cajun that only the cost of the South Holly wort:would be considered as additional work. We had reviewed Cajun's price proposal and recommend the City accept Cajuns price proposal in the amount of$ 5,776.06 for this additional work. No change in Contract Time has been requested.Please advise if the Water Department desires this CMR to be incorporated into a Change Order. Sincerely, FREESE AND NICHOLS,INC.
