Road - Miami Intermodal Center NW 21st Street Improvements
This project consisted of the improvements of roadway reconstruction of NW 21st Street from East of NW 42nd Avenue to NW 37th Avenue. Scope included storm water drainage installation, requiring tie-in to an existing 60” RCP outfall by introducing a 20TN Box Culvert Control Structure. Installation of this new drainage system required MCM to work around numerous existing utilities and adjust water & gas valve elevations due to roadway grade changes. Additionally, drainage & lighting conduit crossings on the local roadways required MCM to relocate existing utilities that were in conflict with roadway reconstruction. One of the most intricate and difficult task of the project was installing a new 42” drainage pipe above an active existing FPL duct bank, below an existing 3” gas line with an existing 6” clay sewer line and 6” water main along both sides of the new drainage pipe. MCM was able to complete the installation of all underground work without disruption to active utilities, successfully completing the project 30 days ahead of the contractual date of substantial completion.
As the FDOT Construction Project Manager, I can attest to their excellent performance, concentrated efforts on the success of the projects and good working relationship throughout the life of the projects. The success of these projects was a result of their cooperation and prompt attention to unforeseen issues, along with close coordination with subcontractors and the Department to ensure a timely completion.
