A great case study @Simon Murray. Why do you think the knowledge of managing building projects from 100 years ago seems to have been lost to the project management and construction professions? As you mention, and can be seen from their autobiographies, Paul & Bill Starrett brought both an intimate understanding of building projects, and a practical desire for continuous improvement. There might have been a connection to the Scientific Management movement of the same period in the UK triggered by Taylor and followers in manufacturing, but I've not come across any specific references. Do you know any? The photo in your main article shows No1 World Trade Centre in the background. 90 years after the ESB this took us about 6x longer to build and cost about 8x more /m2 (30% over budget). A compare-and-contrast would be fascinating.
