Project Description:

Groundcheck was commissioned by the esteemed Kayan Group to undertake a crucial geological investigation and soil testing project encompassing the access road area for the Sungai Kayan PLTA in Malinau, located in the Kalimantan Utara region. Notably, the soil investigation was conducted while earthwork and developmental activities were already in progress. The primary objective of this comprehensive undertaking was to acquire geotechnical and soil parameters, ensuring the road’s capacity while facilitating slope stability analysis.

To fulfill this significant task, Groundcheck efficiently mobilized soil testing equipment from Jakarta to the remote Malinau area. Groundcheck deployed one drilling rig, a complete set of Cone Penetration Testing (CPT) equipment, a dedicated CBR testing equipment, and a highly reliable Dynamic Cone Penetrometer (DCP) equipment.

With an unwavering commitment to precision and thoroughness, Groundcheck successfully executed a total of 30 boreholes, strategically positioned across the project area. Additionally, our diligent team performed dozens of surface in-situ tests utilizing the Dynamic Cone Penetrometer (DCP), providing comprehensive insights into the soil’s strength and compaction characteristics.

At Groundcheck, we understand the criticality of reliable data collection in engineering projects. We ensured that our clients would have accurate geotechnical and soil information. Throughout the entire investigation, Groundcheck prioritized adherence to stringent health and safety protocols, safeguarding the well-being of our personnel and the environment. Moreover, we maintained a meticulous approach to project management, ensuring timely execution without compromising the quality and integrity of the data collected.

In conclusion, Groundcheck successfully carried out the geological investigation and soil testing project for the access road area of the Sungai Kayan PLTA in Malinau, Kalimantan Utara. Our comprehensive approach, efficient mobilization of advanced equipment, and unwavering commitment to precision have solidified our reputation as a trusted partner in geotechnical investigations
