Bear Cut Underground Utility Construction Project

The Bear Cut Underground Utility Construction Project showcases DMSI’s technical expertise in complex horizontal directional drilling (HDD) operations within highly sensitive coastal and bridge environments. This critical infrastructure improvement involved installing new 20-inch water mains beneath the West Bridge and Bear Cut Bridge along the Rickenbacker Causeway, ensuring uninterrupted service while enabling reconstruction of the bridge superstructures.

DMSI installed approximately 1,400 linear feet of 20” water main beneath the West Bridge and an additional 3,000 linear feet of 20” water main across Bear Cut Bridge via HDD. Each section was precisely engineered to meet the challenging geological and environmental conditions of the area. Upon completion, DMSI performed controlled pipe tapping into the existing system to ensure seamless integration, allowing the existing water main to be decommissioned without service disruption.

Extensive public outreach and coordination efforts were conducted throughout the project to minimize impacts on local traffic, bridge operations, and surrounding communities, maintaining the flow of utilities and access across the Rickenbacker Causeway.

The objectives are to streamline processes, maximize resource utilization, and deliver measurable outcomes that create long-term value. By leveraging our technical skills, proven experience, and commitment to excellence, we aim to not only meet but exceed expectations. Communication and transparency will remain at the core of the project, fostering trust and alignment at every step.

Ultimately, this project represents an opportunity to showcase our capabilities while building a foundation for sustained success and future growth.

This project underscores DMSI’s leadership in complex infrastructure construction, marine HDD operations, and bridge utility coordination. By combining technical innovation with strict environmental compliance and proactive public engagement, DMSI delivered a resilient and future-ready water transmission system for the City of Miami and Key Biscayne communities.
