FROM: Charles Folch, Acting City Engineer DATE: May 15, 1991 5 U 9J SUBJ: Approve Plans and Specifications for Improvements to West i 79th Street, East of Trunk Highway 101; Authorize Advertising for Bids; Project No. 91-8 ' The plans and specifications for the West 79th Street Improvement Project have been prepared in accordance with the City Standard Specifications for construction, and accomplish the scope of improvements as described in the feasibility report. Preparation of these plans has yielded a refinement of the ' project work item quantities from the feasibility report. Minor revisions to the quantities and cost estimates are typical as more detailed information becomes known during the plan preparation phase. The work item unit costs have also been adjusted to reflect the current market conditions displayed in recent bids received on similar sized City projects. At 1 the present time, bids for these smaller sized projects have not been as favorable as in the past few years. There are a few important factors that have an affect on this such as the amount and size of other jobs available for bidding, economic conditions, recent and forecasted weather trends, ect. Currently, there are a lot of available projects and the weather has been less that cooperative for construction activities. As a result, the engineer's estimate for the construction cost has been increased to $62,275.00 to reflect a 1 refinement of project quantities and the current market conditions. This is approximately $4,300.00 higher than the construction cost estimate from the feasibility report. Given the important timing coordination with the Valvoline Rapid Oil development, I would recommend that we proceed with the advertising for bids on the project. If the bids are found to be unfavorable, alternatives for 1 increasing the project funding and/or reducing the overall cost will have to be investigated. Therefore, it is my recommendation that the plans and specifications for improvements to West 79th Street, East of Trunk Highway 101, Project No. 91-8 be approved and authorization be given to advertise for bids.
