The project is to re-design and replace four sets of the driving mechnisms each of which is to drive a pair of heavy silding door panels open and close and each Panel weighs 7.5 metric tons and is 5 metre high.

The project following the completion of the 2nd RDS project was another challange to us. We were required to complete the project two month ahead of schedule and accomplished it by end of 2020 on time. (Hong Kong started lockdown residential buildings from late January 2021.)

We are very thankful that Mr. KK Choi, Frankie, the hardware designer and mechanical engineer of sevestudio and our business partner, has done a great job in the project. We express our gratitude to Mr. CF Kwok, our software engineer, for his efforts and dedication to the project before his retirement.
