PROJECT BENEFITS

www.portofmiamitunnel.com

• Provide a direct connection between the Seaport, Airport and the Interstate Highway System

• Maintain PortMiami as the county’s second leading economic generator

• Relieve congested downtown Miami streets of Port passenger and cargo traffic, improving safety as trucks also traverse areas of pedestrian activity

• Facilitate ongoing and future development plans in and around downtown Miami

TUNNEL BORING MACHINE

• TBM cutter head withan outside diameterof 42.3 feet (as highas a 4 story building)

• 361 foot long trailingsupport gear madeup of 6 gantries

• Total length of theTBM is 428.5 feet long(more than a footballfield).

Tunneling Profile Section & Cross Passages

• Tunnels are approximately 4200 ft. long

• +40 ft. under the bottom of Government Cut & approximately 120 ft. below the surface at deepest point

• 5% Grade

• 5 cross passages

Page 16: 2.1 port of miami tunnel cei

www.portofmiamitunnel.com

CROSS PASSAGES

• Five cross passages, or emergency exits, are being built between the two tunnels.

• Cross passages are approximately 700 feet

• Cross passages 1, 4 and 5 are not underneath the channel and were pretreated from ground surface using cutter-soil mixing panels that form a grouted block of soil that can be excavated.

• Cross passages 2 and 3, which go underneath Biscayne Bay, are being treated with a brine to freeze the ground, before excavation is done.

CROSS PASSAGELENGTHS

• CP1 – 15 ft.• CP2 – 36 ft.• CP3 – 37.5 ft.• CP4 – 43 ft.• CP5 – 10.5 ft.

CROSS PASSAGES – GROUND FREEZING PROCESS

• There are a total of 44 freezing pipes.

• Estimated freeze time once brine installed at -22◦F is 40 days.

• A small cooling unit is installed in the second tunnel to cool the lining segments and ensure efficient “closing” of ice ring.

• Steel support frame is installed to prevent movements of the first tunnel due to ice pressures.

• Steel door is installed as “fail safe” to be closed in case of an emergency during excavation.

TRAFFIC SURVEILLANCE & CONTROL SYSTEM

The Traffic Surveillance and Control System (TSCS) consists of the hardware and software necessary to monitor and control traffic and improve the safety and quality of traffic flow by preventing or relieving congestion.

Primary Functions & Benefits:• To provide efficient movement of traffic on and around the Project’s roadways

• To provide early detection of traffic incidents that cause slowdown and/or blockages

• To provide a systematic lane control for shifting or redirecting traffic through the roadways & tunnels

Components:• Closed Circuit Television Cameras (CCTV)• Vehicle Sensors• Lane Use Signals (LUS)• Dynamic Message Signs (DMS)• Overheight Vehicle Detection (OHVD)• Portal Traffic Closure Signas (PTCS)• Automatic Traffic Control Gates• Local Field Controllers (LFC)• AM/FM Rebroadcast/Highway Advisory Radio (HAR)• Fixed Signs

TUNNEL MECHANICAL/ELECTRICAL/ANCILLARY BUILDING SCADA SYSTEMS

The SCADA system contains the computer hardware and software necessary to perform all monitoring and control functions for the Mechanical, Electrical and Plumbing (MEP) Systems.

“Monitoring & Controlling” functionality for following systems:• Tunnel Ventilation• AC & ID• Tunnel/Stormwater Drainage• Tunnel Lighting

“Monitoring Only” functionality for following systems:• Carbon Monoxide Monitoring• Fire Alarm and Detection• Fire Suppression• Hydrocarbon Monitoring• Electrical Distribution• Communications Systems• Building Systems

UNIFIED OPERATOR INTERFACE

The Concessionaire will provide a unified operator interface that integrates the TSCS and the Tunnel’s Mechanical/Electrical/Ancillary Building SCADA operator functions into a single unified interface.

Unified Operator Interface Main Functions:• TSCS and SCADA Alarm Notifications and Acknowledgement• TSCS and SCADA System Device Control• Cross Platform Alarm and Device Control between the TSCS and SCADA Systems• Incident and Event Tracking and Logging
