• The Blue-Green (or turquoise) Book: The Conditions of Contract for Dredging and Reclamation Works contains specific provisions appropriate for dredging projects (and which can also be adapted so that it is suitable for contracts that include, or wholly comprise, contractor-designed works) (2nd edition, 2016).

• The White Book: a form of consultancy agreement where consultant is to be appointed by employer or another consultant (5th edition, 2017).
• Sub-Consultancy Agreement: intended to be used where a consultant appointed under the White Book wants to sub-contract part of the services (2nd edition, 2017).

Both the 1st and 2nd editions of the Red, Yellow and Silver Books areas mentioned above as, following publication of the 2nd editions in December 2017, the 1st editions remain on sale. Given the complexity of the new 2nd editions it has been reported that FIDIC has acknowledged that users wishing to continue with a simpler, shorter form of contract should consider continuing to use the 1st editions and it is likely that the 1st editions will continue to be widely used in the market (so therefore this section still includes a summary and commentary on the pre- 2017 versions).
