Pillar 28 on MRR2 to get support brace

Postby admin » Tue Aug 12, 2008 10:06 am

KUALA LUMPUR: The Public Works Department (JKR) will affix a temporary support brace on the affected Pillar 28 of the Middle Ring Road II (MRR2) by the end of next week as part of its proposed eight-week work programme to fully restore damages.

Called a "tie-frame", the metal structure will temporarily hold the pillar to facilitate repair works and investigations into its three carbon fibre reinforced plastic panels that fell off on Aug 3, which led to a partial closure of the highway.

This is in addition to ensuring the safety of motorists using the highway, said JKR branch director of civil engineering (structure and bridges) Dr Ismail Mohd Taib.

"We hope that all works will be done in eight weeks, and with the tie-frame in place we are able to carry out a full investigation on the cause of the defect.

"It is a tight deadline, but we are trying very hard to meet the target," he told reporters Tuesday after briefing Public Accounts Committee (PAC) chairman Datuk Seri Azmi Khalid during the latter's visit to the site.

Similarly all traffic lanes will be open for use by then. Currently one of the six lanes on the highway has been cordoned off.

Earlier during a press conference Azmi said that the PAC was satisfied with their findings concerning the latest incident, but that the costs for installing the tie-frame and repair works was being determined.

Similar incidents where cracks were detected on the MRR2 were in 2004 and 2006. Controversy has also risen over some RM70mil that has been spent on repair works in the two cases.

Azmi said that they did not want to point fingers, but wanted to focus on getting to the root of the problem.

He also pointed out that Pillar 28 was built by German contractors as an "example pillar" to be followed by local contractors. He said that it was the only pillar out of 26 which used carbon fibre reinforced plastic panels which was problematic.

"The cause of the problem is still unclear, and that is what we are looking at now. It could be material failure or the system of that particular pillar itself. This will take some time for JKR to assess.

"But for now we are satisfied with the findings of the way the project was supervised and the appointment of consultants," he said, adding that the appointment of consultants was carried out under the advise of the Board of Engineers Malaysia.
