Re: REVISED, CMR-011 (request for time extension/sequence changes) for North And South Holly
WTP Upgrade -Ozonation Facilities
Dear Mr. Chris Harder,
The purpose of this writing is to make a fonnal request for time extensions I sequence changes on the above
referenced project. We are requesting the following:
• Extend the interim milestone portion of Phase 4 ( commissioning of Ozone Generation Building &
commissioning of orth Holly Ozone Contactor) to and in conjunction with interim milestone portion of
Phase 5 ( commissioning of South Holly Contactors)
• No change to the completion milestones (su bstantial completion) June 25 , 2012 and (final completion)
August 9 , 2012. However, for clarification purposes, it should be mentioned that the Ozone System
performance testing is not required for substantial completion .
Our justification for the requested time extensions I sequence changes can be attributed to the loss of 30 + days
due to above normal precipitation, particularly the January 25 , 2012 and February 18 , 2012 rain events that
flooded critical vault excavations causing extensive dewatering and demudding work. We also have performed
extra critical path work associated with (1) underground obstructions with North Holl y conversion yard piping
(2) proposed relocation of meter vault and extra depth of valve vault and (3) proposed modifications with air
scour I chemical piping in the South Holly filter resulting in the accumulation of another 10 + days .
It should be mentioned that with exception to the requested changes above, all other designated milestones will
remain unchanged . Your consideration of this request is appreciated
J ectively ,
Ro~~~
