I'm all in for Design-Build "Done Right" or we may as well play dice in an alley.
I'm also all in for promoting Structured Collaborative Partnering (SCP) - one of DBIA's Best Practices. I urge you to explore the International Partnering Institute (IPI) website and discover for yourself why this is a critical ingredient to achieving success in D/B.
Personally I'm addicted to Triathlon (Sprint Distance only) which keeps me busy and exhausted!
