The proposed flooding mitigation and infrastructure improvements being implemented on Indian Creek Drive (AIA), is a Florida Department of Transportation (FDOT) roadway. The design and construction of this project within the right-of-way requires FDOT approval.
On March 9, 2016, the Mayor and City Commission adopted Resolution 2016-29332 approving a Department Funded Agreement (DFA) between the City and the Florida Department of Transportation (FDOT) for the cost sharing of a construction project on Indian Creek Drive from 26th to 41st Streets. The infrastructure improvements under this agreement included a new storm water drainage system, pump station, seawall, roadway, sidewalks curbs and gutters, all to meet the new flood elevation requirements. The scope also includes the replacement of driveways, light poles, signs, signals and pavement markings to match the new roadway alignment and configuration.
On June 8, 2016, the Mayor and City Commission adopted Resolution 2016-29456, approving the award of a professional services agreement to Ribbeck Engineering, Inc., in the total amount of $407,851, to develop the Design Criteria Package (DCP) and conceptual plans for approximately 0.85 miles of Indian Creek Drive. The conceptual plans were required as reference to the DCP and were developed in accordance with FDOT design criteria as well as the City of Miami Beach contract requirements.
The DFA stipulates that the project shall be implemented in two (2) construction phases. The “Interim” Phase construction plans were required to construct the underground drainage component, including drainage pipes ranging in size up to 72 inches in diameter, drainage structures, 24 inch diameter storm drainage pipes along the side streets, the pump station structure and roadway drainage system reconstruction. The “Interim” Phase is currently Substantially Completed. The “Ultimate” phase includes the roadway reconstruction component, raising the roadway and harmonization to the final grade.
On April 26, 2017, the Mayor and City Commission adopted Resolution 2017-29839, authorizing the negotiation of Amendment No. 1 to the Professional Services Agreement with Ribbeck Engineering, Inc., in the amount of $863,171.92 plus a $86,317.19 contingency, for a total amount of $949,489.11, to prepare a set of “Interim” construction plans from 25th to 26th Streets, and 26th to 41st Streets, including side streets along the entire project limits. The approximate length of roadway for this expanded project scope was 1.7 miles.
On October 18, 2017, the Mayor and City Commission adopted Resolution 2017-30070, authorizing the negotiation of Amendment No. 2 to the Professional Services Agreement with Ribbeck Engineering, Inc., in the amount of $1,056,347.77, plus a $158,452.17 owner's contingency of fifteen percent (15%), for a total amount of $1,214,799.94, to complete the “Ultimate” Phase final signed and sealed construction plans for the entire project limits. The scope of work included detailed roadway, traffic control plans and analysis, seawall plans, drainage analysis and plans, signage, signalization, pavement markings, lighting and related improvements. The scope also included a Design Variations memorandum and reports including crash data analysis and cost benefit ratios required by FDOT and electrical and mechanical design of the pump station to reduce the time and cost of temporary pumps.
The City and FDOT staff determined that rather than proceeding with a design/build construction methodology, the Ultimate Phase work would be better accomplished by first completing the design plans for the Project, and then selecting a contractor, via an Invitation to Bid process, to perform the construction work. On September 21, 2018, Invitation to Bid (ITB) 2018-054ZD was issued for the Indian Creek Improvements from 25th to 41st Streets, with a Bid Opening date scheduled for November 12, 2018.
Due to the change in the project procurement method, increase in the scope of work and construction price escalation, FDOT is increasing their cost sharing participation for this project. A revised Department Funded Agreement (DFA) with FDOT is being presented to the City Commission, for approval on October 17, 2018.
At the request of City Administration, Ribbeck Engineering Inc. submitted a negotiated cost proposal (Attachment A) in the amount of 308,360.46, plus a ten percent (10%) Owner’s Contingency of $30,836.05, for a total of $339,196.51, for performing subsurface exploration to further identify potential utilities conflicts, modifications to roadway and drainage design resulting from owners requests to modify harmonization plans for the adjacent properties, parking lanes modification to meet FDOT criteria, additional utility coordination, special handrail design to meet new city criteria and additional coordination efforts. These additional services are necessary to further refine the final construction plans.
This cost proposal was submitted to the Public Works Department and Office of Capital Improvements Projects for further review and recommendation. City staff reviewed the proposal and found that the amount was fair and reasonable.
