It is my understanding that this project was substantially completed in 1990 prior to my tenure with the City; however, over the past four year s'the project contract was not finaled out due to difficulties with the contractor in completing punch list items and negotiating amounts to be paid for work performed. Over the past few years the project engineer has expended many hours trying to tie up loose ends with this contract. Part of the problem may have been that during 1990 through 1992 Shafer Contracting had been concentrating their efforts on the Trunk Highway 5 improvement project with the City. In any case, the engineer has successfully brought the project to a point where the project may now be finaled out. ' The final payment for this project incorporates Change. Order No. 3 to this improvement contract, pending approval. The project engineer has done an excellent job of detailing the specific additional work items that were performed on the project; the corresponding need for Ae work and the associated additional costs. The total change order ;amounts to $98,301.19 with approximately 60% of the cost related to soil correction operations and aggregate base work. The remaining amount includes expansions to the irrigation system, additional lighting and landscaping per'City request. The project that all of this work has been completed to date: ' It is therefore payment for the work associated with Change Order No. 3 amr — _ded and final contract amount of $777,807.17.
