Common Ducts Construction Projects

●Thousands of Threads and Millions of Strands All Bundled Together

Construction barriers spring up in the middle of the road, the sound of drilling splits the air, and once again the streets are ripped open.
Today’s repairing of water mains is followed by tomorrow’s laying of power and phone lines, and then installing the cable TV lines. Once the common duct system is in place, most of these disturbances will be vanished!


The Underground Common Duct System Control Center●Common Duct System Control Center

The common duct system is an underground passageway network.?Its heart is the control center which operates 24 hours a day, 7 days a week, monitoring the duct system to ensure smooth operation.
The control center is a secure underground fortification: permits are required to enter or leave. A key operational objective is to achieve zero incident and?failure. Therefore, regular flood and disaster prevention drills are performed, with the aim of minimizing the damage caused by natural disasters.

●A Mysterious Labyrinth beneath Your Feet

The concept behind the common duct system is to incorporate power lines, phone lines, water mains, cable TV, street lighting, traffic controls and similar services into shared underground ducts.
If any service requires repair or need to add a new service, it is straightforward to access the underground ducts without the need to dig up the road. What Are the Advantages of the Common Duct System?
1. Prevent unnecessary excavation of roadways, eliminate disruption to traffic, preserve road surface integrity, and maintain traffic safety?and comfort.
2. Reduce damage to road surfaces, prevent construction disturbances such as excessive noise, vibrations,?pollution, and avoid possible accidents associated with excavation work.
3. It is easy to adjust the position of branching ducts and keep the ducts clear of obstructions.
4. When setting up services, the duct system provides management, maintenance space, and reduces the mixing of incompatible services. It is also very easy to expand or modify services within the ducts.
5. Refine urban comfort, improves the usability of road space, provide better uses for the above ground, and enhance the city's appearance.

●The Common Duct System, More Than Meets the Eye

In most cases, the best time for planning the construction of a common duct system is in conjunction with the development of new towns or suburbs, the rezoning of rural areas,?the construction of rapid transit or the?underground railway systems.
Under the short and medium-term objectives of Taipei City Government, there are 10 common duct systems.
The plans were released to the public on 7 August 2003, and construction began in conjunction with other major public construction works.?6 systems have been completed:
1. The Civic Boulevard system was completed in September 2000 and is fully operational;
2. The Keelung River reclaimed land system was completed in March 1999 and is also fully operational;
3. The Nangang Software Park system was completed in April 2006 and is also fully operational.
4. The Zhoumei Expressway system was linked up in March 2006. These operational common ducts are functioning properly. Excavation restrictions on the road surface are rigidly enforced, and there has been no need to excavate so far.
5.The Eastern Extension Underground Railway system was completed in June 2011 and is fully operational;
6.The Dadu Road system was completed in June 2011 and is fully operational.
7. The Xinyi Line system was completed in May 2015 and is fully operational.
8. The common conduits of Nanjing line was completed in Dec 2016 and is now operating.
9. Phase 1 of the common conduits of Fuguo Road was completed in Dec 2015 and is now operating.
10. The Shilin-Beitou Science Park common duct was completed in April 2017 and is now operating.
