Changi Airport

The Civil Aviation Authority of Singapore (CAAS) is harnessing the power and capabilities of Tridium’s NIAGARA Framework united with Cisco’s IP router and switching technology in the development of the new Terminal 3 building at Changi Airport.

The result is a fully integrated IP-based supervisory system for the many different controls and environmental monitoring sub-systems being installed as part of the project. Tridium’s versatile web-serving, building services control solution is also being applied to cover the existing Terminal 1 and Terminal 2 facilities at the Airport, achieving vastly improved and integrated site-wide building management.

The new Terminal 3 at Changi Airport is a $1.5 billion project scheduled for completion in early 2008. It will add a capacity of 20 million passengers a year, bringing the total annual capacity to 64
million and adding another 28 aerobridge gates to the Airport. The installation of Tridium’s NIAGARA Framework will ensure rapid, comprehensive and successful integration of the Terminal’s range
of building services equipment, including chillers, pumps, access control, fire alarm and other systems without the need for any special gateways, expensive programming or BMS supervisors. At
the same time, the project’s systems integrator, CHA, is extending this winning Tridium / CISCO approach to the other two Airport Terminal’s which were originally constructed in 1982 and 1990
respectively.

Changi Airport’s complex array of multi-vendor control sub-systems, featuring devices from Cylon, Andover, Singapore Technologies, Invensys and Barber Colman, comprise in total over 50,000 control
points on Terminal 3 and a further 60,000 control points across Terminals 1 and 2. Thanks to Tridium’s NIAGARA Framework and high performance CISCO routers and switches, these sub-systems will all be connected by a Giganet Fiber Optic backbone network in a single, open, fully interoperable and web-based control environment running on HP Servers. This solution will allow the full fiber ring bandwidth to be utilized, facilitate information and application sharing across the site and guarantee the highest standards of network reliability for the CAAS.

The NIAGARA Framework will talk to each controller using its native protocol and respective network in one common, distributed and genuinely open environment, irrespective of controller type and manufacturer. No fewer than eight independent communication protocols are used by devices at Changi Airport, including BACnet, LONWORKS, and Modbus. By supporting multiple open field bus
protocols, this Tridium approach is ensuring complete freedom of equipment specification through best in breed selection on the project. The issue of controls protocol compatibility is rendered
irrelevant.

Graphical information will be served up via the NIAGARA Framework as web pages to ensure that supervisory actions can easily take place through any secure access internet connection. These will include data viewing, collection, trend logging and archiving, centralised operation and adjustment of sub-systems, and equipment maintenance, fault-finding, alarm handling and time scheduling.

Each Air Terminal at Changi features a dedicated NIAGARA System which is equipped with Marathon Hot Standby Functionality on all servers. This ensures that in the event of one system failing, either of the other two systems will be able to handle the increased load and automatically take over within five seconds.

The NIAGARA Framework will be embedded within Tridium JACEcontrol units installed at different points throughout the Airport complex. Because the control system can be engineered via a web-browser, it is able to support multiple access and parallel binding locations, helping to speed up installation and commissioning time.

“NIAGARA FrameworkTM unites with Cisco’s IP router and switching technology to create an irresistibly powerful solution."

“A single, open, fully interoperable and web-based control environment will be created running on HP Servers.”
