Bosch equips Hong Kong-Zhuhai-Macao Bridge with customized security solutions

Shanghai – The Hong Kong-Zhuhai-Macao Bridge relies on customized security solutions from Bosch to ensure safe operations. The world’s largest sea-crossing bridge was opened by Chinese officials late October 2018. Spanning 55 kilometers in length, the Hong Kong-Zhuhai-Macao Bridge directly connects Hong Kong to Macao and then to the Chinese city of Zhuhai for the first time. At a total cost of USD 20 billion, it is a major boost for China’s Greater Bay Area, an emerging industrial and technological hotbed that is home to 68 million people and a showcase project for Bosch Building Technologies.

The large-scale project was built over the course of eight years using 400,000 tons of steel and includes underwater tunnels and two artificial islands that serve as customs ports. Ensuring the security of these two islands, where drivers need to present special permits to use the new bridge and pass customs checkpoints, was a priority from the start.

Securing vital infrastructure

With a proven track record of equipping critical infrastructures such as airports, hotels, commercial buildings and underground metros, Bosch Building Technologies won the contract to provide the artificial islands with video surveillance, intrusion alarms, as well as public address and voice evacuation systems.

On the island between Zhuhai and Macao, the Bosch partner Shanghai SAGA Electronic Technology Co., Ltd. installed more than 5,700 Bosch loudspeakers and over 260 amplifiers which are all managed via the PRAESIDEO Digital Public Address and Emergency Sound system. Fulfilling a key customer request, the installation incorporates 15 different models of ceiling, wall mount, and line array speakers to blend in with the facility’s modern interior. Furthermore, Bosch was able to match Macao’s local standards by custom-ordering solutions with British power cord, programmed with graphic interfaces in traditional Chinese lettering.

On the island outside of Hong Kong, which is home to a customs clearance port, Bosch partner Pro-United Co., Ltd. installed 2,200 public address speakers of various models, including outdoor speakers for the travel inspection building. Experts also adjusted 200 vari-directional array loudspeakers to balance sound variations from different building materials. “The Bosch technical team and partners used professional software to simulate the sound pressure level of a specific area and comprehensively simulate the entire project to ensure that the selected products can meet the requirements of different areas in the actual application,” said Lin Lizhi, Bosch Building Technologies.
