4) Retaining Wall capable to avoid the slope
failure occurrence
As a general understanding, the retaining wall do able to retain the soil of the slope. However, there are several issues that could lead to disaster:
a) Poor construction of the retaining wall
b) Lack of maintenance work such as cleaning up the clogged drain and treat the eroded area at slope.
5) The slope already there about a decade ago. It is safe
A natural slope can fail suddenly without any advance sign even though it is already there for years. Even thou there are no sign of failures, the Factor of safety (FOS) might be low or reaching at a critical level.
6) The Environment Impact Assessment (EIA) report guarantee the slope safety.
The EIA report only describe the impact to the environment due to development proposal in one area and their surrounding. It did not check or taking account the engineering aspect of the slope in details whether it is safe or requiring a remedial method or not A detail study, analysis and slope design works only can be implemented once the EIA was approved and before the approval of earth work has been released.
7) Geology report indicate that the slope is safe.
The geology report only describe the history of the soil and rock formation. It also provide the local geology properties, types of existing rock, types of soil layer, weathering grade and types of minerals within the said area. Only a report from engineer or geotechnical report would take account the field information, lab test result and detail analysis to show the safety level of the slope
