Engineering, Procurement and Construction

EPC providers (also known as EPC contractors) provide every aspect of a construction project. EPC consists of developing the design, delivering the materials, and constructing the project. Companies often use EPC contractors as the contractor can build an entire facility or plant without the purchasing company needing to hire any additional third parties. Once the project is completed the contractor turns it over to the purchasing company; this is also referred to as turnkey construction.


The engineering portion of the contract may include the front end engineering design (FEED), which typically includes creating process flow diagrams, PIDs and site plot plans. The FEED may also be handled as a separate contract as a method to determine budget costs for the project prior to the EPC contract.

The EPC engineering will also typically include:
• Specifications
• Drawings
• Bills of Materials
• Issuing requisitions
• Technical evaluation of supplier proposals


The procurement portion of the contract will typically include:
• Requests for quotations
• Purchase orders
• Fabrication
• Transportation


The construction portion of the contract will typically include:
• Permits
• Temporary facilities
• Mobilization
• Foundations
• Equipment (mechanical & electrical)
• Piping
• Instrumentation & controls
• Testing, commissioning and start-up
