South Florida Rail Corridor Phase IV Double Track

The South Florida Rail Corridor (SFRC) Phase IV Double Track project involved upgrading seven miles of the corridor to provide two mainline tracks. RS&H provided construction engineering and inspection (CEI) services for the project, which including providing full-time, onsite project engineers, technicians and inspectors to manage, coordinate, document, observe, and record all activities required to facilitate scheduled construction in accordance with the approved design documents, schedules, and budgets.

The new track was constructed with 136# RE Continuous Welded Rail (CWR) on concrete ties that incorporate the fast clip system. The project connects two existing sidings, the Opa-Locka Siding and the Miami-Plantation Siding, which were completely upgraded with new rail and ties as part of the project. The track bed within the limits of these sidings was reconstructed from the sub-ballast up, while the track bed between the sidings was completely new.

In addition to the rail mainline and siding construction, other elements of the project included:

• Two No. 20 interlockings
• Construction of five new grade crossings
• Reconstruction of two existing grade crossings
• Replacement of all required grade crossing signals and equipment
• Multiple industry turnout connections
• Reconstruction of an existing CSXT storage and switching yard
• Three crash walls around highway overpass columns
• Three retaining walls
• Two new railroad bridges
• Modification of an existing railroad bridge

The project was coordinated with concurrent construction activities at two separate Tri-Rail station expansion projects, thus required active coordination and scheduling of two independent prime contractors, CSXT, the FDOT construction contractor, Tri-Rail Operations, Amtrak, and CSXT Freight.
