The Sungai Buloh-Serdang-Putrajaya line of the Mass Rapid Transit (MRT) is on track to be completed within its stipulated timeframe, according to project director Datuk Amiruddin Ma’aris as reported by the Sun.

The company is expected to achieve another milestone in its development of the rail line when the first of its 12 tunnel boring machines (TBMs) go into service next month, he said. The project director also expressed confidence that the line would be opened to public by July 2022; Phase 2 of the Sungai Buloh-Kajang line and therefore the line in its entirety was operational from July last year.

“Going by the current rate, we are quite confident we can achieve (completion of the SSP Line) similar to what we did with the SBK Line,” he told the daily. The first TBM for the SSP line’s underground works will commence boring by next month, with the first machine being assembled at the Bandar Malaysia North station in Kuala Lumpur, according to the report.

“Once assembled, we will do some testing before finally starting our boring. We expect Prime Minister Datuk Seri Najib Abdul Razak to launch the TBMs some time in March,” he said. Twelve TBMs are required for the SSP Line, compared with eight required for the SBK Line due to having more underground stations (11 for the SSP compared to seven for the SBK), with a longer underground alignment (13.5 km compared to 9.5 km).

Regarding safety concerns, MRT Corp has taken all aspects into consideration prior to commencing work on the underground line, Amiruddin said. The most common concerns among the public included traffic diversions which may cause congestion, along with noise from the construction sites, he added.

The final tunnel boring machine for the SSP Line is expected to be launched in the middle of next year. Rewinding to its beginning, Phase 1 of the MRT Sungai Buloh-Kajang (SBK) line commenced operations at the end of 2016.
