Building projects require many parties to succeed and even then an educated building occupant may struggle to understand and use design features. Communication is increasingly important in project delivery - although if everything is done for the client's benefit why can each party appear so antagonistic? And in international projects even 'simple' industry terms can have different interpretations. Through examples of international projects (China, Middle East, Far East, USA, and Europe) communication (or the lack of communication) resulted in problems and success stories. The main case study will be a 500+ metre high Indonesian net-zero building.
