In July, I wrote:
The Los Angeles Times has a column that makes a similar point:
It took 410 days to build the Empire State Building; four years to erect the Golden Gate Bridge. The Pentagon took two years; the Alaska Highway just nine months. These days it takes longer to build an overpass.
While I have some guesses, I have no idea why construction, once started, takes so long these days. It isn’t environmental regulation (once construction has started) as the Times suggests and, as I said, presumably we have better tools.
Does anyone have the answer? If you have expertise in this area, please write your thoughts in the comments area. Thanks!
