| Posted: 28 Jun 2011 03:46 AM PDT IT HAS been five weeks since a landslip occurred in Bandar Puteri 9 and the residents living near the site are still having sleepless nights - worrying that the situation may take a turn for the worse. They want the developer to reveal the cause of the landslip and to solve the problem instead of just repairing the collapsed retaining wall. Bandar Puteri 9 Residents Association chairman Peter Lim said the residents were worried over soil erosion at the slope as there was water flowing out of the pipes at the foot of the slope. "We're afraid that it would soften the ground result in another landslip," he said. Part of the retaining wall collapsed on May 20, affecting part of Jalan Puteri 9/2. The road is the only access for 58 bungalow residents there. Work is being carried out to rebuild the wall. However, the residents said the developer and the local authority had failed to provide them with a clear answer on how the landslip occurred during a meeting at the Subang Jaya Municipal Council (MPSJ) headquarters in USJ 5 last Friday. Residents association deputy chairman Billy Koh, whose house is located near the landslip area, said no one could guarantee that the ground was stable. Lim said the Public Works Institute of Malaysia (Ikram) could not suggest remedial measures as there was no report of soil investigation. C.C. Chu said the road only had one layer of 50mm premix (instead of two layers) and six inches of crusher run (instead of 12 inches). The residents measured the exposed layers after the retaining wall gave way. "There should be sand below the crusher run but there wasn't any," he said. Another resident, Jacob Samuel said the cracks along Jalan Puteri 9/2 were getting longer and that the patch-up work was not solving the problem. Koh also pointed out that two of the slabs that made up the retaining wall had cracked. A spokesman of the developer said their appointed geotechnical consultant had initially indicated in a meeting on May 23 that the landslip was probably caused by underground water. "They have recommended constructing horizontal drains to release the hydrostatic pressure which might build up behind the retaining walls. Ikram had agreed to this too. "The seepage at the sewerage pipes along Jalan Puteri 9/2 and the water pipe in Jalan Puteri 9/2A, have been rectified," the spokesman said. The developer added that the soil investigation work was scheduled to start this week. "Meanwhile, all monitoring instruments have been installed in accordance with the requirement of geotechnical consultants for monitoring purpose," he added. On the safety of the slope, the developer said the readings from the monitoring instruments indicated that the settlement or displacement was insignificant and the situation appeared to be stabilising. "But monitoring is still in progress. Ikram and geotechnical consultants have been appointed to study the stability of overall slope and retaining wall, and to propose any further reinforcement work," the spokesman said. The immediate remedial work at the collapsed wall has been completed. The horizontal pipes are being constructed at the wall and expected to be completed by mid-July.Permanent drainage diversion work is also being carried out and expected to be completed by end of July. On the issue of water gushing out from the pipes at the foot of the slope, the developer said its geotechnical consultant had clarified at the meeting last Friday that it was a positive sign as it would reduce the hydrostatic pressure behind the retaining wall. "Based on the water sampling test conducted by Syabas, the water consists of chlorine and hence is from Syabas pipes. "Even though the leakage from the water pipe tapping point at 19, Jalan Puteri 9/2A has been rectified, water can still be seen flowing out at the foot of the slope. We will continue to take samples for testing to identify the source of the water," it said. The developer also clarified that the retaining wall is a Modified Anchored Earth Retaining Wall System designed and endorsed by a professional engineer, and the rusty bars were only observed at the stretch of the wall around the area where the sewer pipes leaks occurred. "The engineer who designed the retaining wall explained that the rust was due to the bars being in contact with the sewer discharge. "He clarified in the last meeting that the reinforcing bars used in the wall were cold galvanised as additional protection," it said. On the cracks on Jalan Puteri 9/2, the developer said the construction of the horizontal drains involved the extraction of existing casings and as such, minor settlement was bound to occur. "We are advised by our geotechnical consultant to just patch up the cracks as a temporary measure to prevent further seepage of surface water into the ground during rainy days. Permanent rectification of the road will be done once the horizontal drains are completed. "As for the cracks on the concrete slabs on the retaining wall, the geotechnical consultant, design engineer and Ikram have inspected the area, and Ikram has proposed to carry out overall mapping survey to ascertain the situation of the wall and slope. On the residents' claim that the road was not built according to specifications, the developer said it would look into the issue. Full Feed Generated by Get Full RSS, sponsored by USA Best Price. |
