The project includes construction activities over water, utility coordination and adjustments, and environmental protection measures such as turbidity barriers and erosion control systems. The scope of work includes 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 existing bridge is located along NE 10 Avenue approximately 200 feet north of NE 83rd Street. The project is in Commission District 2, represented by Commissioner Marleine Bastien. The apparent low bid exceeds the Engineer's estimate by approximately 26 percent. 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. ASA Consultants recommended award to Interstate, and DTPW concurs. Proceeding with award at this time avoids the risk of further cost escalation and schedule delays that could result from readvertisement. The contractor meets or exceeds all minimum qualification requirements and has provided the required payment and performance bonds. Pursuant to Resolution No. R-1181-18, 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 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. Interstate Construction, LLC is deemed a responsible contractor. The existing bridge, 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. The project will demolish the existing structure and construct a new bridge.
