I had good reason to revisit and re-acquaint myself with the working details of the Be Collaborative Working Form of Contract, (now the JCT Constructing Excellence Form of Contract 2009) over the weekend.   Once again I was stuck by the common sense of the collaborative overriding principle initially written way back in 2003. 

Why cant all projects have this as a guide that sums up the essence of Collaborative Working and Integrated Project Delivery, and is the spirit of working together?
