EPC Full Form, Top EPC Companies - EPC Contractor

 Engineering, procurement, and construction (EPC) EPC contracts (a type of turnkey contract) are a form of contract used to undertake construction works by the private sector on large-scale and complex infrastructure projects. 

Full form of EPC 

What is the Full form of EPC? The full form of EPC is Engineering, Procurement, and Construction. In the construction sector, EPC is a popular type of contract. A contractor-client relationship is defined here. It encompasses all the information about the construction project such as project design, material procurement, and the labor & equipment needed for the completion. It also involves the time limits for the construction process and the amount payable to the contractor.



Under an EPC contract, a EPC contractor is obliged to deliver a complete facility to a developer who needs only "turn a key" to start operating the facility; hence EPC contracts are sometimes called turnkey construction contracts.

In addition to delivering a complete facility, the contractor must deliver that facility for a guaranteed price by a fixed date and it must perform to the specified level. Failure to comply with any requirement will usually result in the contractor incurring monetary liabilities. The EPC contractor coordinates all design, procurement, and construction work and ensures that the whole project is completed as required and in time. They may or may not undertake actual site work.

Various abbreviations used for this type of contract are LSTK for lump-sum turnkey, EPIC for engineering, procurement, installation & commissioning, and EPCC for engineering, procurement, construction, and commissioning.

Use of EPIC is common, e.g., by FIDIC and most Persian Gulf countries. Use of LSTK is common in the Kingdom of Saudi Arabia. The use of EPCC is common in Qatar and some other countries.

Few points about EPC

The contractor and client will address each stage in-depth to prevent ambiguity and variance with the client’s requirements.

Whenever the contract is signed, the contractor must maintain the costs under budget and finish the assignment within the timeline specified.

The arrangement under which an EPC contractor is responsible for completing the project within the specified budget and time is generally referred to as an LSTK (Lump Sum Turn Key) Contract.

An EPC, LSTK, or EPCC all are the same types of contracts. This form of contract is covered by the FIDIC (International Federation of Consulting Engineers) Silver Book

containing the title words EPC/turnkey. The initials EPCM are also encountered frequently on international projects, but this is very different from EPC. EPCM is a services-only contract, under which the contractor performs engineering, procurement, and construction management services. In an EPCM arrangement, the client selects a contractor who provides management services for the whole project on behalf of the client.
