Pioneer in the construction industry with innovative technologies

Innovative Construction Method

The construction industry would like to make changes by implementing “Construction 2.0” advocating “Innovation”, “Professionalisation” and “Revitalisation” to uplifting the efficiency and sustainability of the industry, increasing productivity, enhancing supervision and quality assurance, improving site safety and reducing environmental impacts.




In this regard, as a pioneer in innovative technologies within the construction industry, CKR has introduced and implemented various innovative construction methods in the CKR contracts.

Building Information Modelling (BIM)

BIM is adopted for generating three-dimensional models by digital representation throughout the construction period, facilitating the project team in making accurate judgments. BIM demonstrates actual building components of the whole structure by combining numerous working drawings and information, which enables the provision of relevant information to the project team during the construction stage. It can increase certainty, provide low-risk designs, reduce wastage, improve delivery on our projects, and enhance communications among the project team.

Through BIM, the project team perform a variety of analysis to enhance the construction quality by optimising the planning and design as well as improving coordination.

Automatic Canopy Installation System (ACIS)

Under the Central Tunnel contract, the Contractor is required to carry out, amongst other things, the construction of an approximately 2.8km-long dual 3-lane tunnel. In order to enhance safety performance and to avoid risk of personal injury during the installation of temporary canopy supports at fault zones and tunnel portals, the project team has pursued an alternative construction methodology, namely automatic canopy installation system, which reduces labour intensiveness of the canopy installation process. This system provides a fully mechanised installation of canopy pipes which allows remote controlled operation for the safe connection of canopy pipes. Meanwhile, it saves the workers from direct contact with the moving hydraulic drilling machine. It is worth mentioning the system is the first-ever application in Hong Kong.

Blasting Face Access Control with Smart Camera

Given that the handling of explosives is considered as high-risk activity, the Central Tunnel project team has installed the smart camera on site serving as the access control of blasting restricted zone. This artificial intelligence image recognition system enables real-time monitoring of blasting face. When there are any unauthorised entries to the blasting restricted zone, warning signals will be sent to the site supervisor and the registered shotfirer for immediate follow-up action.

NAMI’s Self-Compacting Backfill Material

“Self-compacting backfill material” is a controlled flowable backfill material jointly developed by the Highways Department and NAMI. Its self-levelling and low strength characteristics could expedite the backfilling process by eliminating the need for compaction and sand replacement test. This material can also be placed during wet condition and heavy rain. Comparing with the use of “Self-compacting backfill material” with conventional soil backfill, “Self-compacting backfill material” has a better performance on efficiency, safety, environmental, dependence on spacious area and dependence on manpower or machineries.

6 nos. of trials were successfully conducted from September 2020 to April 2021 at various locations of Kai Fuk Road Footbridge and Underpass S21. 300m3 in total volume of NAMI’s self-compacting backfill material was adopted. Self-compacting backfill material has better performance in terms of efficiency, operation cost, spatial requirement, resources/manpower, machinery, safety and environmental performance than conventional soil backfill.

Over-height Vehicle Detection System (OVDS)

Connection bridges will be constructed to link up the Central Kowloon Route with West Kowloon Highway and Lin Cheung Road.  Erection of steel portal frames across Lin Cheung Road is necessary during the construction of the connection bridges.  To prevent over-height vehicles from hitting the erected portal frames and ensure the safety of the workers, an OVDS is installed at Lin Cheung Road.

When an over-height vehicle is detected, the LED warning message displays, sirens and flashing lights will be switched on to alert the driver of the over-height vehicle to slow down and park the vehicle at the emergency stopping area under the assistance of site personnel. The implementation of the OVDS can prevent hitting of the portal frames by over-height vehicles and safeguard the workers.
