Kuala lumpur: The Public Works Department (JKR) has been instructed to carry out a detailed technical investigation to determine the actual cause of the flooding incident that led to the collapse of a retaining wall near Phase 1B at Jalan Abang Haji Openg, Taman Tun Dr Ismail (TTDI), yesterday.
According to BERNAMA News Agency, Works Minister Datuk Seri Alexander Nanta Linggi said JKR has also been directed to assess the structural integrity of the affected area and recommend additional mitigation measures without compromise. He emphasized the need to identify and address any weaknesses in terms of implementation, supervision, technical compliance, or site management immediately. "The Ministry of Works (KKR) will not compromise on matters involving public safety," he stated in a Facebook post today.
Immediate actions have already been taken at the location, including clearing works at the incident site, removal of hoarding along Jalan Abang Haji Openg, installation of concrete barriers with geotextile over a stretch of about 200 metres, as well as desilting works and repairs to the Erosion and Sediment Control Plan system at the construction site. Nanta highlighted the importance of these measures in stabilizing the situation and reducing subsequent risks.
Yesterday, the retaining wall near the project site for the completion of remaining works under the Bukit Kiara Federal Park Administrative Zone Development - Phase 1B at Jalan Abang Haji Openg collapsed following heavy rain. Preliminary reports indicated that heavy rain between 3.30 pm and 5.30 pm caused water overflow from the project site. Initial observations suggest that water capacity from the hillside led to an earth bund rupture, which flowed into silt trap 1.
The public drainage system downstream was found to be unable to effectively accommodate the flow, partly due to the presence of utility obstructions in certain sections. This led to water ponding, overflow onto the public road, and exerted pressure on the existing retaining wall, causing part of it to collapse along with the hoarding.
Nanta urged all parties involved in the project to extend full cooperation to the authorities and comply with all technical instructions issued. He assured that KKR will continue to monitor developments from time to time and ensure that follow-up actions are taken in a transparent and responsible manner, with a focus on public safety. "I extend my sympathies to the affected residents and assure them that KKR is committed to ensuring that recovery, stabilization, and preventive measures are implemented as quickly as possible so that such incidents do not recur," he said.
