COUNCIL MINUTES AUGUST 10, 1998 necessary lien waivers and withholding affidavits have been submitted to staff thereby meeting the requirements of the construction contract. Mr. Ahrens indicated the project included the paving of certain trails throughout the City and construction of a trail along the north side of Aqua Lane. Also, wear course paving was done in new developments. The final contract amount is summarized as follows: Original Bid Amount $185,665.25 Change Order No. 1 $ 15,234.33 Change Order No. 2 $ 14,122.50 Final Contract Amount $215,022.08 Mr. Ahrens referred to a memorandum from John Powell, TKDA, Inc., which discuss the change orders in detail. Change Order No. 1 is a compensating change order for quantity overrun/underruns. The trail construction along Aqua Lane resulted in quantity increases as a result of poor subbase materials that were exposed during construction. Change Order No. 2 is a result of the construction observer noting that the existing rubberized seals used on manhole adjustment rings and castings was not sufficient to properly seal the rings and casting. Since the rings and casting are areas where a significant amount of infiltration can occur or sand washing between the rings, staff directed the contractor to install additional rubberized seals to prevent any infiltration of water or sand. In both change order cases,the problems encountered were not anticipated and it was only after work had begun and the materials exposed that the construction observer noted problems that required correction. If the design of the project had anticipated the poor soils and deficient seals, the resulting contract amount would be nearly equal to the final amount noted above. Staff recommended adoption of Resolution No. 98 - 127. Mayor Sullivan asked if the change orders would be approved under the new Change Order Policy. Mr. Ahrens stated it would have been difficult to bring before Council for approval prior to executing the change orders. Council Member Lyden moved to adopt Resolution No. 98 - 127, as presented. Council Member Bergeson seconded the motion. Motion carried unanimously. Resolution No. 98 - 127 can be found at the end of these minutes.
