PETALING Jaya City Council (MBPJ) workers were kept busy clearing broken tree branches and debris on Jalan 5/60 and 5/64 in Bukit Gasing yesterday morning following a downpour on Tuesday night.

MBPJ personnel from the council’s Quick Response Team as well as Fire and Rescue Department personnel were on hand to help clear the roads.

The landslip is the latest to occur, after a similar incident in Jalan 5/64 on Sunday afternoon.

Nearer to Fraser Tower, contractors were seen cutting an uprooted tree which had fallen and damaged a resident’s car on Tuesday night as she was driving back to her condominium.

MBPJ Engineering Department deputy director Abdul Shukor Mohamed Noor and slope consultants engaged by the council to find ways to strengthen the slope also visited the site yesterday morning to assess the situation.

Council public relations officer Zainun Zakaria said a preliminary study on May 6 found that the slope failure area covered 1,625 sq m, and was due to soil erosion.

Among the possible causes of the slope failure was the sloping topography and constant heavy rain.

“We have put in place short-term measures, such as clearing trees and undergrowth at the affected area and near drains, as well as placing tarpaulin on the surface to prevent erosion,” said Zainun.

In addition, a contractor has been hired to build a gabion wall along Jalan 5/60, measuring two to three metres in height, to prevent mud flow.

The uprooted tree, blocking the roads was also cut up and removed.

Zainun said the council would be using the prism method to monitor soil movement.

For the long-term, however, a soil nailing system, together with a beam grid, will be used to create a berm along the slope.

Additionally, the drainage system near the slope will also be upgraded to reduce water seeping into the soil.

“The contractor for the soil nailing project also just received his letter of appointment today, and will start clearance work as soon as possible to prevent further mishaps,” said Zainun.

The contractor has been given seven months to complete the project.
