THE overall progress of the Mass Rapid Transit Sungai Buloh-Serdang-Putrajaya (MRT SSP) Line has reached 58.9% completion rate as at the end of August this year, said project manager for work package V205, Dr Tey Chun Yean.

The entire project is on track to be completed within the timeframe, with Phase 1 from Sungai Buloh to Kampung Batu station to be opened by July 2021, and Phase 2 from Kampung Baru to Putrajaya Sentral station by July 2022, he added.

Commenting on the public transportation system in the nation, Tey hopes the government will increase its allocation on maintaining and building public infrastructure projects in the upcoming Budget 2020.

“If we are serious about reducing our dependence on personal transport, I think the government should increase their spending to maintain on public infrastructure projects.

“My personal hope is that we will have MRT3 as it will provide connecting loop circle system which will be much better in terms of connectivity for the Klang Valley residents,” he said to reporters during a media briefing in Kuala Lumpur last Friday.

MRT3, which aims to cover the hotspot surrounding Bandar Malaysia, Ampang, Bukit Kiara and Sentul, was postponed by Prime Minister

Tun Dr Mahathir Mohamed in May last year, amid concern over its cost to the country.

MMC-Gamuda deputy project director Amir Malik Faeiz said long span erection methods were used in the construction of the MRT SSP Line, which cross the Kuala Lumpur-Seremban Expressway, the Besraya Highway and the Middle Ring Road 2 (MRR2).

“Long spans are defined as spans that are above 40m in length (eg 50m-250m) and are typically used for crossing highways, railways or wide rivers,” said Amir.

Long Span A, which crosses the MRR2 as well as the Keretapi Tanah Melayu Bhd, Express Rail Link and Light Rail Transit tracks, is being employed using cast-in-place segments as it would be too heavy to be transported to the site if precast.

Long Span B crosses over multiple lanes of the Besraya Highway which is a significant obstruction.

“We go through several stages of planning and deliberation before choosing the right construction technique for effective viaduct construction at any point of the MRT SSP Line alignment.

“Using the different variations allows construction to proceed smoothly despite the topographical challenges while being safe, making it ideal for long span erection at this location,” he said.

Launched in 2016 and stretching around 52km, the MRT SSP Line is expected to have a ridership of 529,000 passengers per day upon completion and commissioning.
