Improvement Project No. 87-2 I As requested by the City Council, the West 78th Street Detachment construction I documents have been updated to reflect the current project scope. The plan set is quite extensive and, as such, is not included in the Council packet. A copy of the plan set is available for review in the Engineering Department. I The plan set has been modified slightly to include the turn lane construction on West 78th Street and on Market Boulevard for the Market Square site development and also a turn lane on westbound Bawling Alley Road for the relocated bus I shelter. The engineer's cost estimate reflects these increases and, in the case of Market Square, the turn lane improvements will be assessed back directly to the property owner. By executing the development contract, the developer will II waive his rights to contest these assessments thereby guaranteeing reimbursement to the City. The revised engineer's estimate is summarized in the attached letter from BRW I and includes the costs for these turn lane modifications. The plans will be submitted to the various regulatory agencies for their review after Council approval. We anticipate advertising for bids in February to take advantage of I the bidding climate at that time such that the project construction can start immediately when weather permits in mid-April, 1991. Project completion through the first lift of asphalt is scheduled for October of 1991. II It is therefore recommended that the West 78th Street Detachment construction plans and specifications be approved and authorization given for bidding. II ktm Attachments: 1.
