The 4 FIDIC Books represent the most known and used Standard Contract Forms in engineering field.
As a response to the international dynamics of the construction industry, FIDIC published in 1999 a new set of FIDIC Books.

In Romania, the FIDIC Books were translated and started to be used in 2006, as a result of the agreement between FIDIC and the Ministry of Public Finance and distinguished by the modern administration way, defined by a well defined relationship between parties, a conciliatory attitude that is oriented towards good execution of works.

The latest set of the FIDIC Books offers a standardized and synthetic approach, by limiting general clauses to a number of 20, from over 60, in previous editions.


Red Book: CONS – Contract Conditions for Constructions

The Red Book in the first form of contract issued by FIDIC, published in 1957; this reunites the contract conditions for constructions of buildings and engineering works designed by the Beneficiary (public or private authority).

The Red Book stipulates that the Contractor is responsible for works execution based on a project developed and offered by the Beneficiary or by their representative – the Engineer.

In particular cases, the contracts type Red Bok can allow that the Contractor design certain parts of permanent works, but they are not adequate for the cases where the Contractor design most works.


Yellow Book: E&CP –Contract Conditions for Equipment and Constructions, including Design

The Yellow Book was published for the first time in 1963, in the context of Red Book contractual limitations.

The contract conditions in the Yellow Book are intended for supplying electrical and mechanical equipment, and for the execution as well of the buildings and engineering works designed by the Contractor.

FIDIC recommends the use of Yellow Book in contracts of engineering works and building constructions and implies, as the Red Book, the presence of the Engineer within the project.


Silver Book: Contract Conditions for Turnkey Projects (PAC)

The Silver Book is a standard form of contract intended for turnkey delivered projects, including the infrastructure ones, where the repartition of contractual risks require a stricter approach.

By comparison with other FIDIC Books, the Silver Book leaves more risks in the responsibility of the Contractor, who has the duty to guarantee the initially established price and the observance of stipulated terms.

The Silver Book attributes to the Contractor both the design and the execution of works, in order to e able to deliver a fully complete product; the role of the Engineer is not present within this contract form.


Green Book: Short Form of the Contract

The Green Book, also named the Short Form of the Contract, is used most frequently for works projects having relatively low complexity and value.

This contract form is usually used for civil works designed by the Beneficiary and is preferred through its increased flexibility.
The Green Book is increasingly used in practice in contracts for sub-undertaking.
