The Authors: between Michel and Willy there is nearly one hundred years of construction life, all of it on the contracting side of the fence. Projects have taken them to some dozens of countries in Europe, Africa and the Middle East. They have brushed shoulders -and occasionally crossed swords- with most if not all types of clients, architects, resident engineers, sub-contractors, suppliers and dispute resolution practitioners. They have suffered from nearly all possible shortcomings and errors -including their own- in the construction business. Their practical legacy is priceless.
