Conducted field investigations, including geological mapping and soil sampling, to assess slope conditions.
To study open cut slop and its stabilization by using different geotechnical techniques.
Geological mapping by using RMR, SMR techniques, also use the kinematic analysis of cut slope to stabilize it stratigraphy and
geological formation.

To analysis aims to ensure the safety of slop cut during excavation phases for future development structures.
Having good knowledge to overcome the expected risk assessment of external factor such as environmental condition,
metrology such as heavy rainwater (Flood protection) and hazard collapse etc and to be more conservative for worker safety.

Wedge failure.
Performed geotechnical analyses, including slope stability analysis, soil mechanics, and rock mechanics studies.
Implemented monitoring programs for ongoing projects to assess and mitigate potential slope instability issues.
Contributed to the design and implementation of slope stabilization measures.
Write a detail report of Slop stabilities and deliver clear and concise technical reports to clients, stakeholders, and regulatory
authorities.
