Capabilities

Front-End Engineering & Design (FEED)

Service website

Value-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 website

Full-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 website

Operational 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

Service website

Engineering and design services tailored for aging industrial infrastructure to maintain safe, efficient, and continuous operations.

Process Safety Management

Service website

Risk reduction work helps process plants operate safely and meet applicable codes.

  • Code Compliance Support

    Compliance support addresses applicable process safety requirements.

  • Hazard Evaluations

    Formal evaluations identify and document process hazards.

  • Risk Reduction Planning

    Planning translates hazard findings into practical risk controls.

Plant Expansion

Service website

Engineering support for adding new production lines, extending existing plant configurations, or establishing new greenfield sites from concept to construction.

Owner's Technical Representative

Service website

Technical representation protects client interests during project delivery.

  • Project Phase Representation

    Representation supports clients across design and construction phases.

  • Engineering Churn Reduction

    Technical review helps reduce avoidable rework and engineering churn.

  • Cost Overrun Avoidance

    Project oversight helps avoid unnecessary cost growth.
