STRUCTURAL repairs to an eroded stretch of the Sungai Kayu Ara riverbank have been completed.
The stretch, which lies beneath the LRT Shah Alam Line (LRT3) alignment along Lorong 7A in Taman Kayu Ara Indah, Petaling Jaya, eroded after heavy rain on May 6.
Damansara MP Gobind Singh Deo, during a site visit, said the strengthening work was complete following a RM3mil repair funded by Malaysian Resources Corporation Bhd (MRCB).
Setia Utama LRT 3 Sdn Bhd, the main contractor for the LRT3 project, is a wholly owned subsidiary of MRCB.
Gobind, who is also Digital Minister, said holes in the road had been repaired and the ground beneath it strengthened.
He said minor cracks were reported in several nearby houses and some residents’ complaints still needed attention.
“We have actually dealt with most of them,” he said.
Gobind said the contractor assured him that structures at the site have not been affected, but he had asked Petaling Jaya City Council (MBPJ) and Selangor Drainage and Irrigation Department to report on whether the repairs met state requirements.
“Sometimes we just finish a project and we assume that everything is in order,” he said.
“We have to ensure that what has been done complies with what was agreed upon.”
The completed structural work included a retaining wall, drainage system and outlet pipe from an LRT3 pier.
MRCB Builders director of infrastructure Mohammad Amjad Faruq Mohammad Haniff said rushing water had scoured the ground beneath the existing retaining wall, leaving gaps below its base and causing parts of the structure to shift.
Concrete was placed beneath and in front of the wall to strengthen its base and protect it from further scouring.
He said 38 wall panels were removed and replaced, with a concrete beam built along the top to tie the new sections together.
The original base of the wall was retained as removing it would have required more extensive work close to neighbouring houses, he said.
Mohammad Amjad Faruq said the former culvert was replaced with an open drain to allow the drainage channel to be inspected and maintained more easily.
Gobind said the riverbank would require regular inspections and residents could alert the authorities if they noticed further problems.
