    concrete rib dome calculations engineer

    Well, here is some data, the ribs weigh less than 2,000 lbs, no crane is needed, heck a floor jack can do it.. Only a single mold is needed all the ribs are the same for a dome. Once again, this is done slowly. Doing 75 ribs one a day takes almost 3 months! But by the time the last one is done...

    concrete rib dome calculations engineer
