Good question 683. Why doesn't whomever making the claim that there is "low productivity" cite something? Inquiring minds want to know. This claim appears periodically.

You can get a rough productivity estimate by using the chained Gross Domestic Product by industry and dividing by employees, which are part of that. Note no one in the article has a clue. Finally you can look at how these construction costs are actually derived. And they aren't really based on productivity at all.
