FIDIC’s Emerald Book – A contractor’s charter or optimum risk allocation?

It has been suggested that FIDIC’s new Emerald Book may be “a contractors’ charter for riches”. 1 This article examines whether this new form of contract for underground works by FIDIC and the International Tunnelling and Underground Space Association is too contractor-biased or whether it provides a sensible and pragmatic risk allocation process, in an area of construction and engineering which is well known for claims. If more risks are placed on the Employer in this form of contract, what are the benefits of the contract compared to, for example, an unamended FIDIC Yellow Book?
