In the article, the guy that dived for sand bringing it up in a bucket made $16 dollars a day. He had to dive about 40 feet down. Someone else hauled the sand up that he dove for. This person made less.
So lets say between the two and maybe a boat, $25-35 a day. I looked up how much concrete sand costs... in the US at least I found it for $7 a ton. Are they able to bring up 3 or 4 tons a day per two man team diving down 40 feet? I am skeptical, but maybe there is something I don't understand.
- foofoo55 12y agoThey would only need a 2.7 gallon (USG) bucket to bring up 4 tons per day. But please check my estimate: A cubic yard of sand can weigh approx 3000 lbs, so that's 2/3 of a cubic yard per ton. 27 cubic feet per cubic yard, so 18 per ton, which is 135 USG. 4 tons (from your question) is then 540 gallons, and at 200 dives per day that is 2.7 gallons per dive. I'd bet they do more like 8 tons per day per diver.
- EdwardDiego 12y agoShift seven tons and what do you get...
- jqm 12y ago200 dives a day, lets say they are super and work a 10 hour day (for easy math). That's 20 dives an hour or one every three minutes. Diving down 40 feet and bringing up a 3 gallon bucket of sand, once every three minutes for 10 hours straight again seems... very difficult (or maybe a bit improbable). Perhaps it's a special kind of sand and they get more money for it so they don't have to do quite that much?
