RESOLUTION APPROVING RATIFICATION OF THE CONTRACT AWARD TO KIEWIT INFRASTRUCTURE SOUTH CO., IN AN AMOUNT NOT TO EXCEED $31,000,000.00, FOR THE DESIGN-BUILD SERVICES FOR THE PROJECT ENTITLED REHABILITATION OF BRIDGES NO. 874541 (WEST BRIDGE) AND 874544 (BEAR CUT BRIDGE) ON THE RICKENBACKER CAUSEWAY
WHEREAS, this Board desires to accomplish the purposes outlined in the accompanying memorandum, a copy of which is incorporated herein by reference,
NOW, THEREFORE, BE IT RESOLVED BY THE BOARD OF COUNTY COMMISSIONERS OF MIAMI-DADE COUNTY, FLORIDA, that this Board ratifies the Contract Award to Kiewit Infrastructure South Co., in an amount not to exceed $31,000,000.00, for the Design-Build services for the Project entitled Rehabilitation of Bridges No. 874541 (West Bridge) and 874544 (Bear Cut Bridge) on the Rickenbacker Causeway in substantially the form attached hereto and made a part hereof.
To: Honorable Chairwoman Rebeca Sosa
and Members, Board of County Commissioners
From: Carlos A. Gimenez
Subject: Ratification of Contract Award to Kiewit Infrastructure South Co., for the Design-Build Services for the
Project Entitled Rehabilitation of Bridges No. 874541 (West Bridge) and 874544 (Bear Cut Bridge) on the
Rickenbacker Causeway, located within Commission District 7
It is recommended that the Board of County Commissioners (BCC) ratify the County’s Contract Award to Kiewit Infrastructure South Co. (Kiewit), for the Design-Build Services for the Project Entitled Rehabilitation of Bridges No. 874541 (West Bridge) and 874544 (Bear Cut Bridge) on the Rickenbacker Causeway.
Pursuant to the authority granted under Resolution No. R-32-13, approved by the Board of County Commissioners on January 23, 2013, I approved the Contract Award to Kiewit on April 3, 2013 (attached).
Rickenbacker Causeway, West Bridge (No. 874541) and Bear Cut Bridge (No. 874544), which are located within Xavier L. Suarez’ Commission District 7.
Fiscal Impact/Funding Source
The fiscal impact will be approximately $28,000,000.00 for the design and construction of the bridges, and $3,000,000.00 for the design and construction of the water main. The work is to be funded using Future Financing proceeds backed by Causeway Toll Revenues. The replacement of the water main attached to the Bridges, will be funded by WASD with Water Renewal and Replacement Fund.
Delegation of Authority
The County Mayor or County Mayor's designee has been granted the authority to execute and implement the attached Contract under Resolution No. R-32-13.
The Project will be assigned to Marcos Redondo, Section Head, Bridge Engineering, Highways Division, Public Works and Waste Management Department (PWWM).
The original Bridges were built in 1944 and consisted of a concrete substructure, steel girders, and a concrete deck superstructure. The Bridges were widened in the mid to early 1980’s with concrete substructures, pre-stressed concrete girders and a concrete deck superstructure, and have undergone various maintenance and repair actions through the years in order to extend their life expectancy. The Florida Department of Transportation
(FDOT) conducts recurring bridge inspections, with those performed in 2006, 2007, and 2010 not disclosing any critical findings.
In March 2012, PWWM was informally notified via email by FDOT that the bridge inspection performed on January 7, 2012, found deterioration on various steel beams of the West Bridge, and that PWWM was “to correct such deficiencies before they become a critical deficiency.” As a result, PWWM immediately proceeded to restrict truck traffic to the right outside lane of the West Bridge for the inbound (Eastbound) direction, and as a further precaution moved to effectuate similar restrictions on the Bear Cut Bridge.
This action placed truck loads on the concrete beam segment, not on the steel beams found to be in a deteriorated condition. Additionally, between the months of August to September, PWWM initiated detailed field inspections of the Bridge’s 584 steel beams through the services of an engineering consultant.
This effort also found previously undetected deterioration of the steel beams on the Bear Cut Bridge. This information was transmitted to FDOT, along with the request for a Load Rating in order to determine the load carrying capacity of the Bridges in their current condition. On October 19, 2012, based on the provided information, FDOT notified PWWM that the right outbound (westbound) lane on the Bear Cut Bridge had to be closed to traffic. PWWM immediately closed the lane upon being notified. However, in close coordination with FDOT, PWWM had its consultant re-analyze the Load Rating for the bridges. This led to FDOT’s subsequent concurrence to open the closed lane by restricting traffic to cars on the outside lane, limiting heavier vehicles to the inside lane. FDOT’s formal letter of concurrence was received on November 1, 2012. PWWM implemented these restrictions through the installation of signs and pavement markings. PWWM continues to work closely with FDOT in monitoring and inspecting the Bridges on a monthly basis.
The receipt of the most recent Load Rating for both bridges did not provide the time required for the typical County processes to design, bid, and build a project of this magnitude. PWWM has performed a series of actions in an effort to maintain the safety and operability of bridges in their current condition. A delay to commence the necessary construction activities can further delay the existing restrictions to the use of the bridges, placing a significant and prolonged impact on its users (e.g., Sony Open Tennis Tournament, Miami Seaquarium, Rickenbacker Marina, residents, and visitors).
As a result of the repair work, the existing water main attached to the section of both bridges that will be repaired needs to be relocated. The current water main was installed in 1968 and is nearing its life expectancy. The new pipe will also be increased in size from the current 12 inches to 16 inches. Once installed, the new water main will ensure that the pressure capacity for the pipes leading to the Village of Key Biscayne is maintained.
Additionally, in an effort to improve access for pedestrians and cyclists, the project proposes to widen the Bear Cut Bridge. Once implemented, this work will provide a dedicated lane for pedestrians and cyclists on both sides of the Bear Cut Bridge, separated from vehicular traffic.
This proposed Resolution ratifies the County’s award of contract to Kiewit on April 3, 2013. In the event that this Board votes to not ratify this Resolution, the County will terminate the contract for convenience in accordance with its terms.
