    Just Some Nerd, where is engineering going in the next 5 years? We're in the 2020s. If you read my post referencing NY State's DOT, you know there are 1,126 highway bridges in NYC that are over 53 years old (76.44% of the total). In the 2000s, 77 were built. In the 2010s, 83 were built. From...

    Right, so do like the Beatles and let it be. After introducing Holmes' poem, Gordon wrote the following: The entire physical world is most properly regarded as a great energy system: an enormous marketplace in which one form of energy is for ever being traded for another form according to set...

    verymadmac, I take it you're a fan of post-apocalyptic films. Picture this: A section of the NYC subway system collapses with or without a train underneath. Notified of the event, authorities scramble to stop all service, close the system and send a team of engineers to evaluate the safety...

    Logic is this: If a bridge is a bubble and bubbles burst, you're asking for trouble if you build the first and quadruple and double to quench your thirst; you'll collect the rubble when first comes to worst. That's my New Yo'k say.

    I'd like to clarify that the previous post refers to New York City only. Bridges and tunnels serving the rest of the New York-Newark urban agglomeration of 18,819,000 (as per the UN's data booklet cited earlier) are not included.

    IRstuff, the idea is to see that the Holland Tunnel is 96 years old and flooded when it was 85. NY State's Department of Transportation published Highway Bridge Data for 2022. In NY City, 105 bridges were considered poor/structurally deficient. In total, 1 was from the 1850s; 8 were from the...

    What's the design life of the Holland Tunnel? It opened in 1927 (see picture supra). I wouldn't cross it, even if ACtrafficengr paid the toll. That thing actually flooded about a decade ago, and it's only a decade older than its neighbor the Lincoln Tunnel.

    Bills aren't what I'm getting at. Failures all coming at once are, regardless of disasters. Nobody maintains the tubes of the underground, for example. The structure of a subway system is mostly completed around the same time (yester-year) and will eventually collapse. Printing money is useless.

    Just Some Nerd, I don't believe that at all. In fact, here is a picture of long-term city planning - build and they will come - in the guise of cookie-cutter apartment houses. In the long run it led to the original post. Random is reporting and deleting my previous post because I called this...

    GregLocock, the ellipsis omitted the fact it doesn't exist. Your vision of a success story is based on looking at wallpaper (as you put it). There is no historical precedent for such a large city. Take a closer look at Tokyo's walls and use judgement to realize the magnitude of replacing...

    My dictionary defines engineering as the discipline dealing with the art or science of applying scientific knowledge to practical problems and therefore the point of an engineer is using scientific knowledge to solve practical problems. In the eyes of the engineering community, the...

    Wise are those who question... The protagonist below embodies the world of construction. If you think it should stop, you see an issue. That's all.
