Although First Street is a high volume street, work will be performed during the day, but will be split into phases down the centerline of the street. During Phase 1, either the east half or west half of First Street will be closed to traffic. Two-way traffic will be shifted to the other side of the street and on-street parking will be prohibited. During Phase 2, two-way traffic will be shifted to the side of the street reconstructed during Phase 1. Again on-street parking will be prohibited while the work is performed. Construction of one-half of First Street at a time is necessary because this roadway requires profile milling to reduce the high crown and lessen the cross slope. When the first half of the street is milled, a significant elevation differential along the centerline will be created. Cross traffic will not be allowed, which will require some detouring of side streets during construction. Traffic impacts during construction on First Street are expected and unavoidable, however if the crown of the street is not milled before the overlay, motorists that park along the curb would not be able to open their car door curb side without contacting the curb. Cubby's Dog Park Parking Lot Expansion Both Cubby's Dog Park and the Marilyn Murphy Kane Trail have become popular destinations, and the current 25-stall parking lot is routinely full. This project will expand the parking lot to 40 parking stalls with the use of the HCD grant. Budget The estimated total expenditure for this project is $4,236,095, including a construction contingency of approximately 10 percent of the construction contract ($370,230) and construction services ($152,744). See Attachment 1 for a funding and expenditures summary. Staff recommends the transfer of a total of$714,170 from various funding sources as outlined in the recommendations to complete the funding for this project. Bids Sealed bids for this project were opened on April 2, 2018. There were five bids received, ranging between the low bid amount of$3,707,570.55 to $4,147,575. The low bid amount is approximately 1.74 percent higher than the engineer's estimate of $3,644,000 (see Attachment 2). Past work performed by MCK Services, Inc. was verified to be satisfactory. Staff recommends award of the construction contract to the lowest responsible bidder, MCK Services, Inc. for $3,707,570.55. Consultant Services • Inspection & Construction Management: Staff is recommending the use of consultant support services to support City staff during construction to provide daily inspections and construction management. A full-time inspector/resident engineer will be on-site, working with contractors to augment the current inspection staff. This project requires night time work; our current staffing level does not support the concurrent daytime ongoing projects and a night shift that is required for this project. Carlson Management (CM), one of the City's current on- call Construction Management firms was selected to perform this work. CM has worked on similar roadway reconstruction projects within the city and has an understanding of the City's standards and expectations. Staff is recommending that Carlson Management be retained for the not-to-exceed amount of$90,744. The subject project requires 75 working days to complete. The contract amount Page 4 of 5
