The title is RESOLUTION AWARDING CONTRACT FOR THE PROJECT TITLED REPLACEMENT BRIDGE NO. 874178 ALONG NE 10 AVENUE OVER CANAL A, PROJECT NO. 20240256, BETWEEN MIAMI-DADE COUNTY AND INTERSTATE CONSTRUCTION, LLC, IN AN AMOUNT NOT TO EXCEED $7,559,782.90, INCLUSIVE OF A CONTINGENCY ALLOWANCE OF $630,115.45; AND AUTHORIZING THE COUNTY MAYOR OR COUNTY MAYOR'S DESIGNEE TO EXECUTE SAME AND EXERCISE THE PROVISIONS CONTAINED THEREIN, INCLUDING TERMINATION. The header is from Daniella Levine Cava, Mayor, to Honorable Chairman Anthony Rodriguez and Members, Board of County Commissioners. The subject is Contract Award Recommendation for Replacement Bridge No. 874178 along NE 10 Avenue Over Canal A, RPQ No. 20240256, to Interstate Construction, LLC in the Amount of $7,559,782.90. The staff recommendation is approval. The executive summary states the item seeks Board approval to award a construction contract to Interstate Construction, LLC in the amount of $7,559,782.90 for the replacement of Bridge No. 874178 along NE 10 Avenue Over Canal A. The project will be delivered over a 1,090-day term and is funded through Mobility Impact Fees (MIF). The existing bridge, constructed in 1950, is classified as functionally obsolete and exhibits structural deterioration, including deck cracking, corrosion of structural steel, and deterioration of expansion joints and embankment protection. The proposed project will replace the bridge and bring it into compliance with current structural, safety, and multimodal design standards, including wider sidewalks, upgraded guardrails, and drainage improvements. These improvements will enhance safety, improve system resilience, and extend the useful life of this critical crossing. The recommendation states approval of this contract award to Interstate Construction, LLC for a term of 1,090-days and value of $7,559,782.90 is recommended to address a deteriorating bridge that no longer meets current safety and design standards. Deferring replacement would increase lifecycle costs, exacerbate structural deficiencies and heighten risks to public safety and system reliability. The contract was competitively procured under the MCC 7360 Plan (RPQ No. 20240256), and two bids were received. Interstate Construction, LLC was determined to be the lowest responsive and responsible bidder. The apparent low bid exceeds the Engineer's estimate by approximately 26 percent. This variance was independently evaluated by the Engineer of Record, ASA Consultants, Inc., which determined that the difference is reasonable given current market conditions and project-specific constraints. As documented in the bid analysis, contributing factors include escalation and volatility in bridge construction pricing statewide; limited competition, with only two bidders; and project complexity, including construction over water, proximity to utilities and uncertain permitting durations at the time of bidding. Based on this analysis, ASA Consultants recommended award to Interstate, and DTPW concurs with this determination. Proceeding with award at this time avoids the risk of further cost escalation and schedule delays that could result from readvertisement, while advancing a necessary infrastructure replacement. Board approval is required because the contract amount exceeds the $5,000,000 threshold established under the MCC 7360 Program. The scope states the project is located in Commission District 2, which is represented by Commissioner Marleine Bastien. The delegation of authority is consistent with those authorities granted under the Code of Miami-Dade County. The fiscal impact/funding source states the total fiscal impact of the contract is $7,559,782.90. This amount includes a contingency allowance of $630,115.45 for unforeseen conditions, as well as $628,512.95 in dedicated allowances for off-duty law enforcement, permits, and required program fees. The project is being funded through the following funding source: Program 2000000534 BRIDGE REHABILITATION - COUNTYWIDE IMPROVEMENTS FY 2025-26 Adopted Budget and Multi-Year Capital Plan, Volume 2 - Transportation and Public Works, Page 138, Mobility Impact Fees.

A review of the firm's performance history indicates that, within the last five years, the contractor has completed multiple County projects and received four evaluations in the Capital Improvements Information System (CIIS), with an average rating of 3.8 out of a maximum of 4.0, reflecting strong performance. The Department verified the firm's corporate status with the Florida Department of State Division of Corporations and confirmed compliance with all applicable licensing and qualification requirements. The contractor meets or exceeds all minimum qualification requirements and has provided the required payment and performance bonds. Due diligence included a review of safety and compliance records. Pursuant to Resolution No. R-1181-18, Occupational Safety and Health Administration (OSHA) Form 300 logs for work-related injuries and illnesses for the past three years are on file and available for review. No significant safety concerns or adverse findings were identified. Compliance checks also confirmed adherence to County requirements, including the Mandatory Clearinghouse, Inspector General provisions, and applicable ordinances such as Sea Level Rise considerations. No adverse findings were identified that would impact the contractor's responsibility determination. Based on this review, Interstate Construction, LLC is deemed a responsible contractor with the experience, capacity, and performance history necessary to successfully deliver the project. The background states the existing bridge (No. 874178), constructed in 1994, is located along NE 10 Avenue approximately 200 feet north of NE 83rd Street. The structure exhibits multiple deficiencies, including cracking in the deck, caps, and piles; corrosion of structural steel beams; deterioration of expansion joints; and erosion of embankment slope protection. The bridge is classified as functionally obsolete, as it does not meet current crashworthiness standards for bridge railings and approach guardrails and does not accommodate current pedestrian and bicycle safety standards. To address these deficiencies, the project will demolish the existing structure and construct a new bridge that meets current structural, hydraulic, and multimodal design standards. The scope of work includes, but is not limited to, maintenance of traffic; removal of the existing bridge; construction of new substructure and superstructure elements; installation of prestressed beams and reinforced concrete components; roadway reconstruction, milling and resurfacing; drainage improvements; installation of guardrails, barriers, and signage; and construction of widened sidewalks, bicycle accommodations, and Americans with Disabilities Act (ADA)-compliant pedestrian features. The project also includes construction activities over water, utility coordination and adjustments, and environmental protection measures such as turbidity barriers and erosion control systems. The document is signed by Roy Coley, Deputy Mayor. No public comment or stakeholder sentiment is stated in the document.
