Prasarana clarifies on Works at Kelana Jaya LRT Line Extension
Syarikat Prasarana Negara Berhad (Prasarana), the project and asset owner for the LRT Line Extension Project, views with concern over recent statements made by several parties in regard to the project covering areas around Taman Subang Alam and Alam Megah in Shah Alam;
and Putra Heights and the construction of Station 11 and 12 for the LRT Kelana Jaya Line.
As an establishment responsible in bringing transport convenience to the public, we would like to emphasise that the safety of people reigns paramount to Prasarana when undertaking its projects and in providing its services; and that at no time would safety be compromised in discharging our duties.
In doing this, Prasarana and its contractors have been working closely with all the relevant agencies – both at Federal and State levels especially in securing all the necessary approvals and permits including for pre-work.
This includes all the relevant local councils as well as the state’s economic action committee - Majlis Tindakan Ekonomi Selangor (MTES), which is the state’s high-powered committee that is chaired by YAB Menteri Besar of Selangor and comprises key state excos, state secretary, state financial officer and other key personnel in the administration of the state government.
The subject of alternative alignment via Taman Alam Megah to Putra Heights, which was raised by certain parties, had actually been considered, discussed, studied and decided upon by MTES. And, after all the deliberations, YAB Menteri Besar of Selangor had on 24th February 2011 approved the original alignment as proposed by Prasarana.
The decision was made by YAB Menteri Besar of Selangor after presentation of the public survey results by Merdeka Centre, an independent body appointed by MTES at a meeting on 23rd September 2010. The survey specifically covered residents in Putra Heights and
Alam Megah in getting their opinion on two alignments – the original alignment and the proposed alignment by MBSA.
It should be also noted here that this survey is over and above the official public survey required under the Land Public Transport Act 2010 that was carried out by Ministry of Transport in 2009, which was in favour of the original alignment.
Upon this decision, on 25th May 2011, the Land Public Transport Commission issued its final approval for the Railway Scheme for the sector concerned (i.e. Ch13.069 to Ch 17.405).
The safety of the alignment is underlined further on 20th June 2011 when the Department of Environment issued its final approval for the Environment Impact Assessment.
Prasarana would like to confirm that advance works had already started at Station 12 for the LRT Kelana Jaya LRT LEP line. This is in accordance to the approval given by MTES, which decided at a meeting on 19th April 2012 for the issuance of work order for Station 11 and
12. Current work, however, is only confined at Station 12 at this stage.
Again, Prasarana would like to stress that all works undertaken by Prasarana and its contractors would only commence after issuance of the necessary permits and approvals by the relevant authorities.
On the subject of safety, we would like to highlight a statement made by the Honorary Secretary of Institution of Engineers (IEM), Professor Dr Lee Teang Shui in addressing the safety concerns raised by geologist Dr Tajul Anuar Jamaluddin and residents of the Taman Subang
Alam, which was published by The Sun newspaper on 3rd June 2011.
He wrote: “IEM notes that the issues of public safety mentioned in the article pertain to the work of Engineers and concern engineering practice. The institution would like to clarify on the technical aspects of these issues in order that the public may be correctly informed to make reasoned decisions.
To claims that the sags and crests of the land constitute a differential settlement and hence it will be hard to estimate the length of foundational pillars needed for the track, Lee said that the
highs and lows of a terrain can be either natural or have been re-profiled by human activities, like earthworks cutting and filling.
“There is no technical difficulty in building a foundation within the requisite safety standards to support any structure to be built on it. Professional Engineers would carry out investigation to characterize the subsurface conditions prior to selecting the appropriate foundation system and to determine the appropriate founding materials. There is absolutely no technical difficulty in determining the length of the foundation piles, should the necessary engineering processes be
carried out properly.
To claims that the work was not only about inserting pillars into the ground and that the subsurfaces of some crests might be too soft to sustain the weight of a running LRT car; and it could cause the pillars to subside, Lee said that the statement is based on presumption that the foundation is not founded on competent and stable founding materials.
“If the foundation is appropriately designed and founded, the subsidence of pillar would be within the tolerable limits of a safe track design, and shall not pose any technical concern,” he explained.
To claims that the existence on the site of the proposed stations of a type of soil which cracks, and hill slopes that might not be sustainable in the a long-run, Lee said that the stability of ground supporting any structure shall be carefully assessed and the necessary stabilisation works shall be determined.
“In all engineering problems technical solutions, with due consideration of buildability and financial limitations, that conform to accepted safety standards can be designed and built. However, long term sustainability of any structure does not just depend on good
engineering design alone; but on other factors such as proper maintenance, usage and other causes.
“In summary, the above-mentioned works come under the purview of Engineers, and it is a normal engineering scenario for Engineers. A competent Engineer would be able to ensure the public safety as top priority in his/her proposal. With the employment of suitably qualified professional engineers and the right method of construction and technology available in Malaysia, the stations can be constructed safely at the proposed sites,” Lee added.
In this context, Prasarana would like to stress that engineers working for the LRT extension project are highly qualified and highly experienced in ensuring all safety matters are being observed strictly. On top of that, the contractors are strictly supervised by Prasarana and officials from the Occupational Safety and Health Department, Ministry of Human Resources.
With this explanation, we hope that we have addressed all the safety concerns.
