Short summary experiences

I started my career as a site agent for a road construction company in RSA. Quickly became responsible for all contractual matters for all projects (Head Claims). From there I moved to a Dutch International Contractor implementing a suitable contract admin process for their MENA projects. Through this I was approached to join an international Claims Consultancy in the UK, but was stationed in the USA for an off-shore Oil project. From there I moved to Germany as claims manager for a large international power generation company, but still working for the claims consultancy. I was able to gather experience in most forms of power generation such as fossil fired, thermal, hydro, nuclear and off-shore wind. example projects include the Three Gorges Hydro Plant in China, OL3 Nuclear Plant in Finland, Gubrah Power/Desal Plant in Oman, etc.From 2002 I was also involved as contract admin on large international roads projects as well as airports and railway projects and dams. Example projects include New Beijing Airport, New Doha Airport, T3 Dubai Airport, Cologne Frankfurt ICE Railway, In 2009 I decided to concentrate on doing arbitration and adjudication work. To this end I applied for assessment to be listed on the FIDIC President's List of Approved Adjudicators and was accepted in 2012. I am also a Fellow of the Chartered Institute of Arbitrators (FCIArb), as well as a listed Adjudicator for the VBI list in Germany.I provide services for clients that wish to initiate their own in-house contract admin departments by coaching selected staff members into such a position.I have been working with FIDIC Contracts since mid 1990's, and was directly involved in the drafting of the new 2017 version as a member of task group 6B.since 2015 I have also been providing training for FIDIC on their webinar Module 1 advanced series, together with Steen Frederiksen.
