-86- City Engineer Jankowski stated that the second issue concerns the phasing plan of the prosecution of the work. The plan was for T.FI. #47 to be constructed under a phased scheme with the highway in service throughout the construction. Within the vicinity of the intersection of C.R. #5 it has become apparent that the phasing plan cannot be constructed as planned for technical reasons primarily relating to the gear changes in gades between C.R. #5 and T.Fi. #4'7. Two alternatives could be considered resolving this. The first alternative would be to revise the phasing plan by adding more phases to the project in order to keep T.FI. #4? open for the duration of the construction. However this alternative would cost approximately $40,000 to $50,000..A second option, preferred both by staff and the contractor, would be to temporarily close T.H. #47 north of the intersection of C.R. #$. This alternative would be done without additional costs to the City. The contractor would need to provide a minor amount of additional traffic control signage. The closing, would last approximately two weeks, but would have the benefit of allowing the project to be completed more speedily than the first alternative and would also have the additional benefit of ensuring better quality of work, since crossings can be completed in their entirety instead of half at a time. Since most of the traffic already appears to be avoiding T.H. #47 in favor of C.R. #5, staff felt the second alternative may have minimal impact on the traveling public. Mayor Gamec inquired as to when.they would anticipate the closure. City Engineer .rankowski replied approximately three weeks. Councilmember Hendriksen stated that when a project is bid to be constructed under traffic it typically costs more and if the contractor submitted a bid they accepted the contract under traffic. The contractor should either do the work with T.H. #47 open or give some money back to the City. City Engineer fankowski explained that the project cannot be constructed the way the plans were prepared. The construction manager was certain that they were not going to be able to put down asphalt and direct traffic because of ~uts that need to be made. He stated that it would be possible to point out the error in the plan and request a deduct in the project. Councilmember Connolly inquired if it was the same engineer that missed the additional utilities that would have to be moved at the City's expense. City Engineer Jankowski replied yes. Mayor Gamec inquired if residents will be able to get access from 151'* Avenue and 149th Avenue. City Engineer Jmtkowski explained that there would be a full closure at C.R.. #5 and up to 600 feet which should not impact any access to resident/al property. City Council/July 11, 2000 Page 11 of 15
