Precision Underground. We deliver comprehensive Geotechnical Engineering Solutions to provide the geological certainty required for heavy infrastructure on Indonesia’s most challenging terrain.
Construction risks in Kalimantan and Eastern Indonesia often lie beneath the surface. Peatlands, soft clay, and unstable slopes pose significant threats to project timelines and structural integrity.
At PT Pelita Isiana Pratama, we don’t just supply data, we provide advanced Geotechnical Engineering Solutions. Combining over a decade of local geological experience with advanced testing technology, we help mining and industrial clients mitigate ground failure risks before they happen. From initial site investigation to the execution of soil improvement, we ensure your foundation is scientifically sound, cost-efficient, and fully aligned with construction standards (SBU BG003 & BS001) for seamless execution.

Comprehensive Soil Investigation (Sondir/CPT, Boring/SPT) & Topography Mapping.
Calculation and modeling for piles, rafts, and heavy-duty foundations.
Execution of PVD (Prefabricated Vertical Drain), Vibro Replacement, and Pre-loading.
Analysis and reinforcement for mining pits and embankment slopes.
Soil mechanics testing to determine bearing capacity and settlement predictions.
Our approach to Geotechnical Engineering Solutions ensures that every design aspect is scientifically calculated.
Bridging the critical gap between raw data and reality.
We interpret geological findings through the lens of Civil Engineering, ensuring every recommendation is not just theoretical, but practical and ready for construction.
We go beyond simple calculations.
Utilizing industry-leading software like Plaxis and GeoStudio, we simulate complex soil behaviors to predict settlement and stability with high precision before ground is broken.
Achieving the perfect balance.
We rigorously engineer foundations to meet the required Safety Factor (>1.5) without "over-designing," ensuring you don't pay for unnecessary piles or excessive concrete volume.
Our Geotechnical Engineering Solutions deliver tangible value to your project, translating technical accuracy into cost efficiency, risk mitigation, and operational speed.
Stop burying money underground.
Accurate soil parameters allow us to design efficient foundations, significantly reducing material waste (concrete/steel) caused by generic or overly conservative assumptions.
Proactive protection for your asset.
We identify hidden threats—such as deep soft clay or slope instability—early in the process, preventing costly structural failures or differential settlement in the future.
Audit-ready engineering.
All our investigations and designs strictly adhere to SNI 8460:2017 and ASTM standards, providing you with legal security and technical accountability for high-stakes projects.
Minimize project downtime.
With our own fleet of drilling rigs and personnel stationed in East Kalimantan, we ensure rapid deployment to your site, even in remote mining areas or difficult terrains.
Integrated Solution Seamless handover from investigation to civil execution.
Our design recommendations are practical and compliant with SBU BG003 (Industrial) and BS001 (Roads) requirements, ensuring they are "buildable" and legally safe.
In a region defined by complex ground conditions, you need more than just data providers. You need a partner with proven expertise, specialized equipment, and integrated engineering capability to guarantee project success.
We bridge the gap between earth science and structural engineering. Our certified Geologists work side-by-side with Civil Engineers to ensure that every soil parameter is interpreted not just scientifically, but with a direct focus on constructability and structural safety.
We invest in precision. Operating our own fleet of hydraulic drilling rigs and CPTu machinery alongside fully calibrated laboratory equipment, we eliminate data distortion. This ensures your engineering calculations are based on the most accurate sub-surface readings available.
Navigating Kalimantan's unique terrain requires local mastery. With deep experience in East Kalimantan, we have perfected specific methods for handling peatlands and soft marine clay. We mitigate the high risks of regional soil instability that often baffle outside contractors.
We don't just give you a report, we provide Foundation Design and Construction methodology that meets SBU standards. This guarantees that our geotechnical recommendations can be practically constructed using standard heavy equipment and methods.
Clear answers regarding our drilling capabilities, site mobilization, and engineering standards to ensure your infrastructure stands on solid ground.
CPT is ideal for soft soil profiling, while SPT (Boring) retrieves physical soil samples for lab testing and reaches harder layers. We recommend a combination of both for accurate building design.
Yes. We specialize in soft soil solutions using methods like PVD (Prefabricated Vertical Drain), Geotextiles, and Pre-loading to accelerate settlement before construction begins.
Absolutely. Our service includes the Engineering Analysis Report, recommending the type, depth, and dimension of the foundation required for your specific structure.
For a standard site (e.g., 3-5 points), fieldwork typically takes 3-5 days, followed by 7-10 days for lab analysis and reporting.
We strictly adhere to SNI 8460:2017 (Persyaratan Perancangan Geoteknik) for compliance in Indonesia. Additionally, our field and laboratory procedures follow ASTM International (American Society for Testing and Materials) standards to ensure the data is accepted by multinational mining clients.
It depends on the scope. For Deep Boring (Drilling), we typically charge a Unit Price per meter of depth. For Sondir (CPT), it is often per point. Mobilization and Demobilization (Mob-Demob) costs are calculated as a Lump Sum based on the site location and accessibility.
Yes. We specialize in Kalimantan’s challenging terrain. For sites with difficult access (swamps, dense forests, or steep slopes), we utilize Man-Portable Drilling Rigs or Track-mounted machines that can be disassembled and carried by manpower/small boats, ensuring we can reach any coordinate.
You will receive a comprehensive engineering report containing: Field Logs (Boring/Sondir data), Laboratory Test Results, Stratigraphy Profiles, and most importantly, the Engineering Analysis (Foundation recommendations, Bearing Capacity calculations, and Settlement predictions).
For projects within East Kalimantan (Balikpapan / Samarinda area), we can typically mobilize personnel and equipment within 3-5 days. For remote mining sites or other islands, we will provide a detailed mobilization schedule attached to our commercial proposal.
Absolutely. We don’t just deliver data; we provide solutions. If the investigation reveals unstable soil, our engineers will propose Soil Improvement methods (such as PVD, Pre-loading, or Geotextile reinforcement) or recommend specific pile depths to reach the hard layer.
