Rock Slope Assessment at PJU8 Bukit Lanjan
Geologically, any type of rocks is subjected to at least a primary structure (i.e. beddings, unconformities, etc.) and/or secondary structures (i.e. foliation, joint, faults etc.). These structures usually were generalized as planes of discontinuities where it is classified as weak region of the rock mass. In worst case, intersections of any of these structures may lead to rock slope failures by either falls or/and rock slides.
Geoforensic Assessment at TULIP Pipeline ROW
In December 2022, a combined flood and landslide event occurred near Kg Lombong, which affected a portion of the TULIP pipeline right-of-way (ROW) and was suspected to have been triggered by heavy rainfall. The objective of this project is to perform an assessment and identify the possible root cause of the failure.
Detailed Geological Assessment at KP220 of SSGP
In November 2021, a pipeline dig up activity revealed a pipeline parting at SSGP ROW, suspected to be caused by geohazard. Geotechnica Sdn Bhd, in association with Wan Husin & Associates Sdn Bhd, was appointed to perform a geological assessment and recommend mitigation action.
Geohazard Assessment at Ringlet, Cameron Highlands
Geohazards assessment was conducted at the section of the TNB 275kV right-of-way, which was identified as requiring urgent attention following the landslide incidents. The assessment included soil investigation, geophysical seismic survey, and LiDAR acquisition.
Geoforensic Assessment at Lawas (KP139), SSGP
In December 2020, an incident of pipeline failure was reported at the Sabah-Sarawak Gas Pipeline (SSGP) right-of-way in Lawas, Sarawak, resulting in a loss of production capacity (LOPC).
Assessment of Critical Slope in Selangor, N. Sembilan & Melaka
Based on “Penghasilan Peta Bahaya dan Risiko Cerun di Kawasan Gombak Selayang-Rawang-Batang Kali, Selangor dan Cheras Selatan-Kajang-Bangi, Selangor” study in 2017, 20 numbers of locations were identified as critical slopes.
Detail Design for Slope Stabilization at Kajang SILK
In continuation of the Rock Slope Hazard and Risk Assessment, the locations identified with a Very High rating and showing signs of distress and failure were addressed and mitigated. This was done to ensure the safety and stability of the slope, as well as to prevent potential hazards that could impact the surrounding area.
Rock Slope Risk Assessment along Kajang SILK Highway
Several rock slope failures have been reported to occur along this highway since 2009. However, no casualties have ever been reported following the incidents. Therefore, a comprehensive study is necessary to assess the safety of the slope and its surrounding area.
Geohazard Assessment at Amber Courts, Genting Highlands
A landslide was reported occurred at Jalan Genting-Amber Court in Genting Highlands around 5.40pm on 5 Nov 2019 (Tuesday) affecting the main access road. The failed slope approx. 95m in height, consist of 21 numbers of berm located at the toe of Amber Court Apartment. However, no casualties were reported.
SSGP Hazard & Risk Assessment using LiDAR
Jabatan Kerja Raya (JKR) of Terengganu initiated a Slope Hazard and Risk Assessment study for the development of Pusat Ummah at Kg. Baru, Pulau Redang, Terengganu Darul Iman. The aim of the assessment was to determine the likelihood of any landslide failure, the consequence and risk towards surrounding assets and facilities, and to make recommendations for mitigation action prior to any development plan implementation.
