PETALING JAYA: A stop-work order has been issued for the Federal Park Administrative Zone office project in Bukit Kiara following a mud flood and the partial collapse of a retaining wall near Jalan Abang Haji Openg after heavy rain on Saturday (April 18).
Minister in the Prime Minister’s Department (Federal Territories) Hannah Yeoh said in a social media post on Sunday (April 19) that immediate action was taken following the incident.
The project is under the National Landscape Department of the Housing and Local Government Ministry, and cleaning operations were underway.
“A stop-work order has been issued with immediate effect, and a compound has been imposed on the contractor,” she said, adding that she visited the site of the incident with Kuala Lumpur mayor Datuk Seri Fadlun Mak Ujud.
She added that cleaning operations were carried out by the Fire and Rescue Department and Kuala Lumpur City Hall, alongside the contractor, while hoarding structures were removed and the silt trap was repaired to control runoff.
“A control centre has been established by the city hall to coordinate on-site operations, while the Fire and Rescue Department is on standby to assist with emergency relief, if necessary,” she said.
Yeoh said an urgent meeting would be held to reassess mitigation plans, adding that all slope development works in the Bukit Kiara Federal Park area would be reviewed.
“Such works will no longer be allowed to proceed in a broad and uncontrolled manner, and must instead be carried out in carefully managed phases,” she said, urging the relevant agencies to take immediate steps to prevent a recurrence.
Meanwhile, Works Minister Datuk Seri Alexander Nanta Linggi, in a social media post, said the incident was triggered by heavy rain between 3.30pm and 5.30pm, which caused water to overflow from the project site.
“Initial observations indicate that the high volume of water from the hill area caused an earth bund to break, with water flowing into the silt trap,” he said.
He added that the downstream public drainage system was unable to cope with the flow, while utility obstructions contributed to water overflowing onto public roads and placing pressure on an existing retaining wall, which partially collapsed along with site hoarding.
Nanta said the Public Works Department had been directed to carry out a detailed technical investigation to identify the root cause, assess structural integrity, and recommend further mitigation measures.
“Any weaknesses in implementation, supervision, technical compliance or site management must be identified and addressed immediately. KKR will not compromise on matters involving public safety,” he said.
He said immediate measures included clearing works, the removal of hoarding along Jalan Abang Haji Openg, the installation of about 200m of concrete barriers with geotextile, as well as desilting and repairs to the erosion and sediment control plan system at the site.
“These measures are important to stabilise the current situation and reduce subsequent risks,” he said, adding that the ministry would continue to monitor developments and ensure transparent and accountable follow-up action.
