He is familiar with a wide range of standard forms (including JCT, ICE, NEC, FIDIC, IChemE, PPC, TPC, ACE, RIBA etc) and PFI contracts, and a wide range of arbitral rules (ICC, LCIA, UNCITRAL, EDF and LMAA etc); and he has acted in relation to claims concerning projects in the United States, the Caribbean, Russia, Central and Eastern Europe, the Indian sub-continent, Africa, Turkey, Hong Kong and the Middle East (including the UAE, Qatar, Kuwait, Oman and Saudi Arabia) as well as in the United Kingdom.
