COPIES TO: A.V.& C. Construction DESCRIPTION: In October 1989, the City Council awarded Contract 89-7, Shannon Park Renovation, to A.V.& C. Construction. The project improvements included a complete renovation of the existing park with play areas for younger and older children, a shallow pond and spray pool, a plaza area and two fountains, landscaping and drainage improvements, an additional pedestrian bridge over the creek, and parking and lighting improvements. Council also approved Alternates for a railroad-tie path under the existing bridge, a demonstration garden on the slope behind Shannon Community Center, and the replacement of a concrete culvert headwall facing with a river rock culvert. A.V.& C. Construction did not complete the improvements until 149 days after the contract date of completion. The contractor was charged $37,250 ($250.00 per day) liquidated damages to defray the costs of the additional time for inspection and contract administration, and loss of public use of the park. During the course of construction, Change Orders were generated to correct the existing condition of underground spring water in the parking lot, change the water meter size, install a new park sign (the existing sign could not be recycled as intended), adjust field dimensions from design dimensions for crib retaining walls, and alter the wiring and lighting plan since the existing lighting electrical service proved to be unserviceable. Change Orders No. 9 for additional grading on the slope behind Shannon Center and items of work which were not included in the bid items (work under the bridge related to the path and to drainage, additional electrical work, and handrail), and Change Order No. 10 to balance the actual field quantities of work from the original estimated bid quantities are attached to this Agenda Statement for City Council approval. Approval by the City Council is required as the cumulative amount of the Change Orders exceeds the limit which can be approved by the City Manager. The total project is 5.2% over budget, partly due to Staff time for the project completion delays by the contractor, but mostly due to unforeseen items such as the lighting system having to be removed and replaced because of inadequate as-built plans, the parking lot requiring extensive subdrain work and patch paving, and due to items designed into the plans and not included in the contract pay items. The sum of $15,383.44 is being withheld from the final payment until the Stop Notice (Exhibit 3), which was filed by one of A.V. & C.'s subcontractors, has been released, and $20,000 is being withheld as a completion bond for warranty items. The project must be finaled out this fiscal year in order to maintain and collect outside park grant funds. The City Engineer has reviewed the work on the project and determined that it is complete and in accordance with the approved plans and specifications. Staff recommends that the City Council accept the improvements and authorize final progress and retention payment in the amount of $50,414.83 to A.V.& C.
