WORTH, TX E r4zt- YNOLDS, INC. March 2. 2012 Fort Worth Water Department Attn: Mr. Chris Harder. P.E. 1511 11 th Avenue Fort Worth. TX 76102 Re: REVISED, CMR-003 (request for time extension/sequence changes) for North and South Holly WTP Conversion From Gaseous Chlorine and Ammonia Dear Mr. Chris Harder. The purpose of this writing is to make a formal request for time extensions/changes with interim and completion milestones on the above referenced project. We are requesting the following: • Waive the January 16, 2012 interim milestone (North Holly commissioning of sodium hypochlorite). • Extend the interim milestones (North and South Holly commissioning of liquid ammonium sulfate & sodium hypochlorite. with one ammonia storage tank in service) from April 15. 2012 to April 30 . 2012. • Extend interim milestone requirement(installation and commissioning of the 2na ammonia tank) from April 15, 2012 to substantial completion date of May 27, 2012. • No change to the completion milestones (substantial completion) May 27. 2012 and (final completion) July 31, 2012. Our justification for the requested time extensions/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 work areas, made access nearly impossible to many of these areas and required extensive cleanup. We also have or will perform extra critical path work associated with increased quantities with crack injection and sealing of top concrete decks at new hypochlorite tanks resulting in the accumulation of another 10 +days. It should be mentioned that these requested time extensions with the interim and completion milestones are compatible with the North Holly & South Holly Ozone Project startup sequences. Your consideration of this request is appreciated Respectively. Robert Emery Sr. Project Manager File 1.125-13929 cc Ted Gay (Freese & Nichols) Heath Statfeld. 'Matt Hunnicutt (Rev nolds)
