What Is EPC Contracting?
EPC (Engineering, Procurement, and Construction) contracting is a single-point project delivery model where one contractor is accountable for the design, supply chain, and execution of a project from start to finish.
At Swanag, our EPC methodology is engineered for precision. We start with conceptual and detailed engineering, perform finite element analysis (FEA) for structural stability, and integrate BIM-based coordination for civil, mechanical, and electrical systems. Our procurement division ensures optimal sourcing through a vetted vendor network, while our construction teams follow strict QA/QC protocols and real-time progress tracking using digital project management tools.
Whether it’s industrial plants, machine foundations, process facilities, or power infrastructure, our EPC solutions are designed for long-term operational stability and reduced lifecycle costs.
