Capabilities
Front-End Engineering & Design (FEED)
Service websiteValue-added engineering during critical development stages, combining first-principles engineering with conceptual design to establish economic viability and prepare projects for detailed engineering.
- FEL-1: Conceptual Engineering & Feasibility
Initial engineering phase to establish basic project feasibility and define supportive equipment. Deliverables include conceptual block diagrams, process flow diagrams, preliminary equipment lists, and capital cost estimates with ±30-50% accuracy.
- FEL-2: Planning & Specification Development
Refining specifications, project schedules, and utility requirements. Supports site permitting and provides cost estimates with ±20-30% accuracy.
- FEL-3: Project Definition
Comprehensive project documentation for management approvals, investor packages, and EPC engagement. Delivers detailed P&IDs, 3D facility models, process hazard analyses (PHA), and equipment quotes to achieve ±10-20% cost accuracy.
EPCm Services
Service websiteFull-spectrum project delivery integrating detailed engineering, equipment procurement, and construction management to complete industrial capital projects on schedule and within budget.
- Detailed Engineering
Finalizes all construction and field-ready design documentation, integrating constructability factors and early procurement of long-lead equipment.
- Procurement Management
Global and domestic equipment and material acquisition. Includes bid package development, vendor pre-qualification, technical and commercial evaluation, and on-site receiving coordination.
- Construction Support & Management
On-site field support and oversight, offering contractor selection, construction scheduling, site safety monitoring, compliance inspections, rigging plans, and outage planning.
- Investigation & Evaluation Services
Specialized field evaluations including structural load capacity analysis and structural distress evaluations.
Process Optimization
Service websiteOperational analysis improves efficiency in active industrial facilities.
- Bottleneck Identification
Analysis identifies constraints that limit plant throughput or reliability.
- Efficiency Improvements
Improvement planning targets measurable process and operating gains.
- Process Enhancements
Enhancements are implemented within active industrial operations.
Maintenance Engineering
