Case Study
Geoforensic Assessment at Lawas (KP139), SSGP
2021 · Petronas Carigali Sdn Bhd / DNASB
Challenge
In December 2020, a pipeline failure was reported at the SSGP right-of-way in Lawas, Sarawak, resulting in a loss of production capacity — initially suspected to have been triggered by a landslide.
Approach
A multidisciplinary team spanning geology, geotechnics, geospatial analysis and hydrology investigated the incident to determine the possible root cause(s) of the failure.
Finding
Identified the contributing geological and hydrological factors behind the pipeline failure.
Outcome
Delivered a root-cause determination to inform remedial action and reduce recurrence risk along the corridor.

FAQ
Frequently asked questions
What is geoforensics assessment?
Geoforensics assessment is the use of geological and geotechnical methods to investigate causes of ground-related problems like slope failure, cracks, or subsidence.
When is geoforensics assessment needed?
It’s needed when there are disputes, accidents, or failures involving soil, slopes, foundations, or land movement—especially when legal or insurance action may follow.
What does a typical geoforensic investigation include?
It includes site inspection, subsurface testing, data analysis, and a detailed report explaining the cause of the ground or structural issue.
Can geoforensics be used in slope failure cases?
Yes, forensic assessment is commonly used to find out why slope failures or landslides occur, especially in hilly or high-risk areas in Malaysia.
Is geoforensics useful for construction defects?
Absolutely. It helps identify whether construction-related ground movement or settlement is due to design issues, soil problems, or external factors.
What tools are used in geoforensics assessment?
Common tools include Ground Penetrating Radar (GPR), Electrical Resistivity (ERT), borehole sampling, and lab testing for soil strength and properties.
Who uses geoforensics assessment in Malaysia?
It is used by developers, engineers, lawyers, insurance companies, and local councils when there’s a need for expert analysis of ground-related problems.
Does geoforensics involve legal reporting?
Yes, the assessment often includes reports that can be used in court cases or insurance claims, with expert witness support when needed.
How long does a forensic ground investigation take?
Depending on the complexity, it can take a few days to several weeks, including fieldwork, testing, and final reporting.
Why choose Geotechnica for geoforensics in Malaysia?
