The cost overruns on the project came from several sources which were listed out in <br /> Engineering and Infrastructure Memo 2005-76, dated December 5, 2005. A significant <br /> overrun was related to the decision to remove and replace 100% of the curb and gutter on <br /> Powers Boulevard and Country Manor Court. During the initial engineering review of <br /> the street, it appeared as though the e�sting drive approaches could remain undisturbed. <br /> As the removal of the street commenced, it was discovered that the driveways were <br /> integral with the pavement to the extent that leaving them in place would result in poor <br /> street drainage and a poor appearance. Engineering staff determined that the prudent <br /> action would be to incur a cost overrun and remove and replace the drive approaches. <br /> Other cost overruns were related to stabilizing arEas of poorer than expected subgrade <br /> that were discovered at various locations as the pavement was removed. <br /> The majority of cost overruns experienced on the Country Manor project were unrelated <br /> to the pavement type selected by the City and were related to: (1)the decision to replace <br /> 100% of the curb and gutter which resulted in a conflict witli the existing driveways, and; <br /> (2) the patches of e�remely unstable soil under the pavement that were not detected in <br /> the soil borings that were taken during the project design. <br /> 2. Why was the City Council not asked to authorize the added costs to the project prior to <br /> construction? <br /> During a project, when conditions are encountered that will require a significant change <br /> order and probable cost ovemxn, the City Engineer, and often, the Engineering and <br /> Infrastructure Department Director, review the issue and discuss options. Issues often <br /> include: (1) the nature of the problem; (2) the best action to resolve the problem; (3) the <br /> scope of the possible cost ovemm, and; (4) is the problem considered to be an emergency <br /> that does not leave time or opportunity to bring it before the City Council. <br /> Often, on an active construction project, taking time to involve the City Council on a <br /> project cost overrun requires the work on that item to be halted for a period of time, <br /> generally one to two weeks. In the case with the Country Manor street work, the road <br /> was unusable due to the demolition that had occurred with residents isolated from their <br /> homes, when the uniaue drivewav configuration was encountered Shutting the�roject <br /> down and �ayin�possible delav damages to a11ow time to address the Citv Cpuncil with <br /> the problem, did not a�pear to be an acce�table option and in effect required an <br /> emergency response The City Engineering Department felt it was necessary to move <br /> auicklv in order to address the problem and avoid le�� road-usage health and safety <br /> access (fire trucks. ambulances, issues for residents in the area Engineering staff <br /> determined what appeared to be the most prudent course of action and proceeded with the i <br /> intention of informing the City Council of the decision when the project was complete 'I <br /> and the full scope of the overrun was determined along with any other overruns that may ' <br /> arise during construction. <br /> Page 2 I, <br />
