The Challenge

As part of upgrading and modification works at Cheras, the client required multiple lift-related alterations and demolition works at the basement level. The scope included creating new lift panel openings, enlarging existing control panels, hacking selected lift panels, and demolishing a tower crane base footing.

Carrying out basement concrete demolition presented additional challenges, including limited headroom, tight access, and confined working zones where conventional demolition equipment would be impractical and disruptive. The restricted environment required precise planning, controlled execution, and specialised equipment suited for structural works in enclosed spaces.

Our Approach & Result

We executed 5 lift panel openings using Diamond Wall Sawing to achieve clean, vibration-free cuts. 3 lift panels were carefully hacked, while 2 lift button panels were enlarged with precision to accommodate new installations.

For the tower crane base footing demolition, we adopted a strategic approach to basement concrete demolition by utilising Robotic Demolition for its compact size, stair-climbing capability, and remote operation. We combined it with Diamond Wire Saw that is ideal for basement conditions, allowing us to demolish reinforced concrete and cut rebar safely.

Basement works demand a different level of planning and execution, especially when structural modifications and demolition are involved. Our team was engaged to carry out a combination of lift panel modifications and tower crane base footing demolition within a tight, restricted space in Cheras.

We began with Diamond Wall Sawing to create 5 lift panel openings, ensuring straight, controlled cuts without vibration. This was followed by hacking 3 existing lift panels and enlarging 2 lift button panels to suit updated requirements. Precision was critical to avoid damage to surrounding finishes and lift systems.

The project also required demolition of a tower crane base footing located in the basement. Using Robotic Demolition and Diamond Wire Saw allowed us to work effectively in cramped conditions, including navigating stairs and narrow access points. The remote-controlled machines delivered controlled concrete removal and rebar cutting while maintaining safety and minimising disturbance to adjacent areas.
