This First Edition of the “Conditions of Contract for Underground Works” (Emerald Book) is published by the Fédération Internationale des Ingénieurs-Conseils (FIDIC) in a joint endeavour with the International Tunnelling and Underground Space Association (ITA-AITES).

Based on the enquiries on international best practice in contracting of tunnelling and underground construction works conducted by the ITA-AITES during the last fifteen years and on the ITA-AITES Report 006 (“The ITA Contractual Framework Checklist for Subsurface Construction Contracts”, April 2011), these General Conditions of Contract have been specifically drafted by a joint FIDIC – ITA Task Group for use in underground works. Their use may also be appropriate in other types of works that include a significant geotechnical uncertainty.

On Friday 28 August, BTSYM and TAIym will host Matthias Neuenschwander (, one of the industry leaders in dispute avoidance and resolution, for an introduction to the FIDIC Emerald Book.
