These contracts can be complex and involve many different stakeholders, so it’s important to have a thorough understanding of how they work before entering into one.

In an EPC Contract, a single contractor is responsible for the design, procurement, and construction of a project.

This type of contract is particularly useful for large-scale infrastructure and industrial projects, where there are many interrelated components and stakeholders

What does EPC stand for?

EPC stands for Engineering, Procurement, and Construction services. An EPC contract is a type of construction contract that involves the full cycle of a project, from design and engineering to procurement of materials and equipment to construction and installation. In other words, an EPC contract is a turnkey solution for a construction project, where the contractor takes full responsibility for the project from start to finish.

The 3 Phases of EPC! 

The acronym EPC stands for Engineering, procurement, and construction which represents the three phases of this contract.

 Engineering Phase: It involves designing the project and identifying the resources required. This includes conceptual design, detailed engineering, and project planning.

Procurement Phase: This phase involves the selection and procurement of materials, equipment, and services required for the project. This includes vendor selection, procurement planning, and contracting.

Construction Phase: This phase is where the actual construction of the project occurs. This phase includes project management, quality control, and commissioning.

Having a tight grasp over these three phases is crucial for any contractor entering into an EPC contract.

Key contractual obligations in an EPC contract

When a contractor signs an engineering procurement and construction contract, they are committing to take on the extensive obligations and responsibilities associated with the three distinct phases of an EPC contract. These obligations include:

Engineering Phase Obligations: During the engineering phase, the contractor must develop a detailed design and engineering plan for the project, including specifications for all materials and equipment. The contractor must also ensure that the project will meet all regulatory requirements and obtain any necessary permits and approvals.

Procurement Phase Obligations: During the procurement phase, the contractor must purchase all of the materials, equipment, and supplies needed to complete the project. The contractor must also manage the logistics of getting everything to the construction site and ensure that all materials and equipment are of the required quality and meet the specifications developed during the engineering phase.

Construction Phase Obligations: During the construction phase, the contractor is responsible for building and constructing the project according to the plans and specifications developed during the engineering phase. The contractor must also manage the construction process, hire and manage subcontractors, and ensure that the project is completed on time and within budget.

The ability of a contract construction company shines through when they are able to go above and beyond to fulfil these obligations of an EPC contract.

Benefits of EPC

There are several advantages to using an EPC contract for a construction project. Some of the noticeable advantages of an EPC contract include reduced risks, cost savings, and improved project coordination. By having a single contractor responsible for the entire project, there is greater accountability and coordination between the different phases of the project. This results in fewer delays, errors, and conflicts. EPC Contract can also result in cost savings, as the contractor can leverage its expertise and purchasing power to negotiate better deals with suppliers and vendors

Risks in an EPC 

Although EPC contracts offer many benefits, they also come with their own set of risks and challenges.

Some common risks and challenges of an EPC contract include higher initial costs, reduced flexibility, and increased reliance on the contractor. The contractor assumes all the risks and responsibilities associated with the project, which can result in higher initial costs. EPC Contract also limits the client’s flexibility to make changes to the project, as the contract is designed to ensure that the project is delivered according to the agreed terms.

Types of EPC Contract

There are three different types of engineering procurement and construction model of contracts that are commonly used by construction companies, with each type having its own advantages and disadvantages. The 3 types of EPC contracts are:

Lump sum or fixed price EPC Contract: In this type of contract the contractor agrees to complete the project for a fixed price.

Cost + EPC Contract: This contract involves the contractor being reimbursed for actual costs incurred, plus a fee for profit.

Target price EPC Contract: This third type of contract involves the contractor agreeing to complete the project within a target cost, with incentives for meeting or exceeding the target, and penalties for failing to meet the target.
