HomeMy WebLinkAboutA001 - Council Action Form dated May 27, 2025ITEM #:41 DATE:05-27-25 DEPT:PW SUBJECT:2024/25 SOUTH 16TH STREET ROADWAY WIDENING COUNCIL ACTION FORM BACKGROUND: South 16th Street is a Minor Arterial, two-lane rural cross section roadway from University Boulevard east to the Veterinary Medicine Trail where it widens to four lanes to the intersection with South Grand Avenue. While this section of the roadway is owned by Iowa State University, staff has recommended, for this one instance, that the City pay for this improvement since the City's extension of Grand Avenue into S. 16th St. has increased the traffic volume and negatively impacted the intersection operations at S. 16th St. and University Blvd. Following construction, the roadway and trail will be administered by the City of Ames in a roadway easement, which will give the City full control and access. This project will include widening South 16 th Street to four lanes from University Boulevard to the Veterinary Medicine Trail, transforming the roadway into an urban cross section with curb and gutter. The proposed project also includes extension of the box culvert at Worrell Creek and a multi-use trail along the south and north sides of South 16th Street from University Boulevard to the Veterinary Medicine Trail. To accommodate the ISU academic calendar and football season, the project will be constructed in two phases over two construction seasons. On May 20, 2025, bids for the project were received as follows: Bidder Bid Amount Engineer's Estimate $ 3,762,873.00 Con-Struct, Inc.$ 3,625,832.10 Absolute Concrete Construction, Inc.$ 4,184,152.50 All Star Concrete LLC $ 4,232,348.27 Concrete Technologies, Inc.$ 4,327,132.97 Reilly Construction CO., Inc.$ 4,340,501.70 The summary of the estimated revenues and expenses for this project are shown below.

Award the contract to one of the other bidders. 3. Do not proceed with this project. CITY MANAGER'S RECOMMENDED ACTION: By accepting the report of bids and awarding the contract, this project can begin this summer in accordance with the agreed upon schedule with ISU.

Therefore, it is the recommendation of the City Manager that the City Council adopt Alternative No. 1a-b, as described above.
