Ackcio Beam was used to monitor a new road infrastructure construction project with an under-sea tunnel segment. The main challenges related to this project included the large area and complicated layout of the deployment site.
The Tuen Mun–Chek Lap Kok Link is a new addition to Hong Kong’s highway infrastructure and road project in the New Territories, Hong Kong. It comprises two elements: the “Northern Connection” and the “Southern Connection”. Ackcio Beam system was used in the Northern Connection, which included an undersea tunnel, crossing the Urmston Road to link Tuen Mun to the “Boundary Crossing Facilities” (BCF), an artificial peninsula connected to Chek Lap Kok Airport. The tunnel portion is approximately five kilometres in length.
Though the project lies entirely within Hong Kong territory, its construction is associated with the new Hong Kong–Zhuhai–Macau Bridge (HZMB). The estimated cost of the design, site investigation, and construction of the TM–CLKL (including associated works, like land reclamation) is about US$6 billion.
Our client used the Ackcio Beam system to monitor vibrating wire piezometers and strain gauges deployed both within the undersea tunnel segment and the above-ground site location.
Thanks to the convenience of the long-range wireless mesh connectivity provided by the Ackcio Beam system, the construction team was able to monitor all the sensors on the above ground site, as well as the ones inside the tunnel, using only one gateway.
Ackcio Cloud was also utilized for data management in this project to have real-time awareness of the sensor readings and to ensure that the construction work proceeded smoothly with little or no construction risk.
