John started his career as an articled pupil with John Laing and was subsequently sponsored for a building degree at Aston University. He worked for the Laing organisation for over twenty-five years in site management roles and was involved with a number of large prestigious projects including: The Falkland Islands Airport, The New British Library and No 1 Poultry office building. In 1992-`94 John took a part-time masters degree course in construction law and arbitration at King`s College London, where he won a proze for his dissertation on the giving of instructions under building contracts. John combined his practical experience of subcontract management with his construction law knowledge to win a Hudson prize, awarded by the Society of Construction Law, for a paper on subcontract arrangements. In 1997 he won the Hudson Prize again for a paper on Letters of Intent. John joined the Knowles Organisation in the spring of 1997 as a senior consultant, since when he has managed in excess of 130 adjudications. These have most frequently been disputes arising out of subcontracts. It is this width of experience that has inspired this book.
