A LOT of issues related to the Damansara 21 project was explained to residents of Medan Damansara during a briefing by the technical consultant with the Public Works Institute of Malaysia (Ikram) yesterday at the Bukit Damansara Community Hall, which also saw the attendance of Kuala Lumpur City Hall and Federal Territories Ministry officials.
Mohd Taufik Haron, who is with Ikram's forensics unit, explained that three previous proposals submitted by the developer, SDB Properties Sdn Bhd, were rejected by City Hall upon Ikram's recommendations as no buffer zone between the project's boundary and houses at Lorong Setiapuspa 1, 2, 3, and 4 were proposed.
The developer had installed an improper drainage system (it utilised a pre-cast U drainage system, when only cast in-situ drains are allowed for hill-slope developments as the former can cause water to infiltrate into the soil).
The developer also failed to completely address the issue of slope stability at the southern part of the development area and at Jalan Kasah.
Requirements set by Ikram, which are included in SDB's fourth proposal, involve a 4.5m flat buffer zone from the boundary of residents' homes — extending into the boundary of the project area.
There will also be a sturdy wall system utilising hand-dug caisson walls measuring 1.5m in diameter on three layers of the hillslopes, which will increase the FOS to 1.5m.
Then, there will be new fencing for residents' homes and a walkway that will be maintained by City Hall. The estimated cost to the developer is estimated at RM6.6 million.
Meanwhile, also recommended is for City Hall to form a technical supervision team during the construction process.
This will be formed by several agencies — including City Hall, the Public Works Department, Ikram, the Mineral and Geoscience Department, and the Drainage and Irrigation Department. - The Malay Mail
