The main structure of a tunnel needs reliable passive fire protection to maintain its load capacity in the event of a fire. Promat offers you excellent solutions to cover and protect your bearing structure (steel and concrete), taking into account local regulations and aesthetic criteria.

Truck traffic represents 28% of this number (source: PB Americas 2009 Traffic Study). Existing truck and bus routes restrict the port's ability to grow, raising costs for port users and presenting safety hazards.

The POMT is a public-private partnership (PPP) designed to transfer the responsibility of designing, building, financing, operating and maintaining (DBOFM) the project to the private sector.

Public Sponsors are Miami-Dade County-Florida Department of Transportation (FDOT)-City of Miami.

The project was launched in 2010 with the commencement of work on Dodge and Watson Islands while the tunnel boring machine was procured and built.

The tunnel boring rig and hauling equipment were assembled at Watson Island and began excavating the eastbound tunnel towards Dodge Island in November 2011. In July 2012, the eastbound tunneling was completed when the tunnel boring rig tunnel erupted at Dodge Island - Port Miami. Within 3 months, the tunnel boring machine was repositioned and launched from Dodge Island and began tunneling west to Watson Island.

In May 2013, removal of the westbound tunnel was completed when the tunnel boring machine at Watson Island blew up.

Extremely durable and accurate

Interference factors such as dust, heat, smoke or exhaust gases make it difficult to detect fires in hostile and aggressive environments. securiHeat LIST heat detectors are immune to these effects and impress with their high precision, reliability and durability.

Localization of fires in a very short time

SecuriHeat LIST sensor cables contain high-sensitivity addressable sensors whose response behavior can be individually programmed. The spacing of the sensor on the cable can also be selected. The resolution of the sensor is 0.1 °C, which allows for extremely accurate evaluations. It is even possible to specify different detection areas with independent alarm thresholds and individual pre-signal thresholds on each wire, allowing the system to locate alarms with a high level of accuracy.
