The Land Public Transport Agency (APAD) of the Ministry of Transport inspected a section of the MRT Putrajaya Line on 10 August 2020.

The APAD team carrying out the inspection was led by Deputy Director General (Development) Encik Ahmad Radhi Maarof. Hosting the team was Mass Rapid Transit Corporation Sdn Bhd (MRT Corp) MRT Putrajaya Line Underground Tunnels Director Mr Alexander Willian Terry and Underground Stations Director Mr Danny Lim.

The team first had their temperatures screened and had the Covid-19 RTK tests done at the Bandar Malaysia Utara MRT Information Centre. A short briefing on tunnelling and tunnel boring machine operations was conducted, followed by a safety briefing.

The team was then led into the Bandar Malaysia Utara station box where they descended to the base level to access the north-bound tunnel. They walked along the first stage track bed for a distance before accessing the south-bound tunnel via a cross passage.

After crossing back to the north-bound tunnel through another cross passage, the team continued all the way to the Chan Sow Lin MRT Station box. The total distance walked was just over 2km. The tunnels were at the stage of being handed over to the trackworks contractor.

During the walk, the team observed the progress of both tunnelling and underground station construction work. They were also shown the interfacing between the MRT Putrajaya Line project and other projects where both either shared the same right of way or were located very close to each other.

Throughout the walk, the team provided feedback on what they observed. They said they were happy with the progress made so far and that the workmanship of the construction work was of very good quality.
