The Red Book
The Red Book, which is the FIDIC book with the broadest scope
of application, mainly regulates the relationship between the employer
and the contractor. The first edition of this book was published in 1957,
and the fourth one in 1987. Minor changes on the latest edition were
made in 1992. Consequently, the fifth edition, which is the current one,
was published in 1999. Along with this edition, the book’s name was
changed to its present name, Conditions of Contract of Works of Civil
Engineering Construction. The Red Book was envisaged for works
where the employer handles the general design works, while the con-
tractor designs and carries out the construction operations of some of
the plants. In light of the regulations available in the fifth edition, it is
acknowledged that the Red Book is more suitable for relatively simple
works, which are mostly comprised of civil engineering works, such as
water and sewerage systems, pipelines and building construction

The Yellow Book
The Yellow Book that was formed by joining of the Conditions of
Contract for Plant & Design-Build Works for Electrical and
Mechanical Works (the Yellow Book) and the Conditions of Contract
for Design-Build and Turnkey Works (the Orange Book) regulates the
relationship between employers and the contractors, as with the Red
Book. However, the Yellow Book is specifically used for construction
and installation operations that are performed by the contractor. In
construction works that are subjected to the Yellow Book, the contrac-
tor performs plant design, construction and engineering operations.
The Yellow Book is recommended for works that are based upon the
know-how and experience of contractors who are not bound by the
designs and the standards created by the employer. Within this context,
the Yellow Book is suggested for construction of pumping stations,
water and waste purification, as well as industrial plants and waste gas
filtration plants.
