An Understanding of EPC

EPC, the acronym of Engineering, Procurement and Construction, is a prominent term in the Construction Industry. It is a contract agreement between the clients and EPC contractors, where the contractors are completely responsible for all activities starting from the designing, procurement, construction, commissioning and the final step of handing over the finished project to the client. 

Each of these steps contain another set of functions associated with it. The engineering stage includes:

  • Basic engineering
  • Detailed engineering
  • Planning
  • Construction engineering

The procurement phase includes:

  • Logistics & transport
  • Receiving
  • Procurement
  • Invoicing
  • Purchasing

The construction functions include:

  • Electrical installation
  • Mechanical erection
  • Civil engineering

The commissioning phase includes: 

  • After-sales-service
  • Testing & commissioning
  • Modernization of plants

From the very first FEED phase or Front End Engineering Design phase, then to the EPC phase where the actual execution of the designs takes place and to the final stage of completion, EPC companies employ numerous engineers and talented workforce for the neat completion of construction projects.
