Summary of Differences between NEC3 & NEC4
Early contractor involvement (ECI Contract) is a kind of construction agreement in which the main contractor is brought on board early in the project to provide design feedback. The concept permits the contractors to have a say in the scheme's design and recommend cost-cutting measures.
Or in other words, we can also define it as- Early contractor participation (or 'ECI') is a construction contracting strategy that permits a builder to become involved and perhaps begin work before the design is complete. ECI engagements include “CM (Construction Management), GMP (Guaranteed Maximum Price), and MC (Managing Contractor)”.
ECI Contract refers to contractor engagement early in the project development process, which can occur through a variety of methods such as alliancing, management contracting, Integrated Project Delivery (IPD), or even a conditional two-stage contract in a construction project.
The following are some of the benefits of employing ECI:
Contractor involvement at an early stage of the design process can allow them to take part in the design process and design decisions.
If the highway authority does not want to transfer preliminary design ownership to a contractor who is unsuitable for the project, ECI gives them that flexibility. If this is the case, the highway authority can split the first step by hiring the contractor a consultant to provide the advice on the design process that the highway authority will undertake.
This gives the highway authority freedom without requiring him or her to relinquish control of the design process or to negotiate and agree on the full construction contract. ECI is generally used in big-ticket infrastructure projects like port development or highway development, etc where contractors propose an innovative solution, value engineering, practical and constructible design solutions bearing construction cost and duration as a priority.
It can also be used on minor projects like road junction improvement or residential apartment or commercial building construction.

The New Engineering Contract ( (NEC) is a set of contracts that makes it easier to execute sound project management principles and practices while also outlining legal connections.
The New Engineering Contract (NEC), also known as the NEC Engineering & Construction Contract, is a formal system developed by the (ICE) Institution of Civil Engineers in the United Kingdom to guide the preparation of the document for civil engineering projects in order to obtain tenders, award contracts, and administer them. As a result, in the Works Information, they legally specify the roles and duties of Employers (who commission work) and Contractors (who carry out work).
The contract is divided into two parts:
It includes in a variety of ways, making it a family of alternatives. The NEC is a collection of various forms of standard contracts that share the following characteristics:
Early contractor involvement (ECI) permits the Contractor to be selected under a 2-stage ECC contract before the construction detailing is fully defined and priced. This permits the Contractor to participate in the design development of the project as well as construction planning and sequencing.
This method promotes better teamwork, innovation, planning, and value engineering. Where an ECI approach is necessary, NEC has designed it as a supplementary clause to be utilized with the NEC3 Engineering & Construction Contract (Options C & E). This extra clause is proposed to encourage collaboration throughout the project and to share the benefits acquired from collaboration”.
NEC4 is the most recent form of the NEC Contracts, having been released in June 2017. “The NEC4 contracts can be used for a variety of works, services, supplies and from big size projects to small size projects.
The NEC philosophy is established and distinctive mechanisms for partnership, transparent dealing, and robust project management in this updated edition. After receiving feedback from the industry, the NEC Contract has been modified and streamlined to reflect government preferences and evolving best practices.
As a result, the contract is more flexible, clear, and simple to use. NEC4 helps you to complete projects on schedule, within the budget, and with the highest standards, whether you're selling high-value commodities or low-risk ones.
There is only one 'fee %' in NEC4, and it is now also in PSC4. Events in defined cost: the expense of preparing compensation events was expressly excluded from defined cost in the NEC3 priced contracts. This has been criticized as being too tough on suppliers.
