PRECISION FROM WORKSHOP TO SITE
Building Resilient Assets in Extreme Terrains
The synergy between precision pre-fabrication in the workshop and proven field installation methods minimizes the risk of rework and delays.
The main challenges in steel construction and fabrication projects within the energy and mining sectors are remote locations and tight timeframes. PT Tri Daya Maxima answers this challenge with an Integrated Pre-Fabrication strategy.
We shift the majority of operational complexity to our dedicated workshops. By manufacturing precise knock-down components, we accelerate the duration of site erection while maintaining welding and structural quality to international standards, regardless of weather conditions or project locations.

MORE THAN JUST TECHNICAL DRAWINGS
Our Construction Advantages
We do not just hand over technical drawings. As a reliable steel fabrication contractor, we deliver cost certainty, asset security, and ease of field execution through the following pillars:
Welding Quality Certification
All welders hold active certifications (Migas/Depnaker/BNSP) with a strictly maintained Weld Repair Rate of under 2%.
01
Precision Pre-Fabrication
The use of CNC cutting machines and plate rolling in the workshop guarantees dimensional accuracy during field fit-up.
02
Advanced Erection Methods
Mastery of the Jack-Up System allows tank works to be executed in confined areas without the need for giant heavy cranes.
03
Remote Area Logistics Mastery
Extensive experience in mobilizing materials and heavy equipment to remote areas (forests/coastal regions) across Kalimantan for mining infrastructure construction.
04
Precision Synergy Between Virtual Planning and Construction Reality
PRECISION REALIZATION PORTFOLIO: FROM SCREEN TO SITE
We prove that mature design results in seamless construction. Below is our track record of execution accuracy across various industrial sectors.
Featured Project
5,000 KL Storage Tank
Palaran, East Kalimantan | 2025
The main challenge was soft soil conditions. Through structural load analysis, we implemented a Ring Beam foundation connected to a timber pile mattress (cerucuk), ensuring zero-settlement when the tank is at full capacity.
- Material
- Carbon Steel SS400
- Dimensions
- ID. 23.200mm x T 12.618mm
- Standard
- API 650
Featured Project
SSB Sebamban Workshop
Sebamban, South Kalimantan | 2022
The main challenge during the initial phase of this project was the land contour conditions, which had not been fully resolved by the third-party contractor.
Responding to this situation, our engineering team adaptively adjusted foundation elevations in the field, ensuring workshop construction remained precise and on target with the timeline.

Featured Project
Magazine Warehouse
Swalang, Central Kalimantan | 2025
The main challenges in this project included unready site conditions and discrepancies in initial field data, where the actual land contour was dominated by rocky terrain.
Responding to this anomaly, our engineering team agilely escalated and made adaptive design modifications, ensuring structural integrity remained optimal and the construction completion schedule was maintained.
