That's around $2900 of today's money. Also, noting that Charlie Brown was one of the surveyors helpers.
And W. M. Chaplin did the records research. Charlie Chaplin's dyslexic brother?
The guy providing the stones gets 50% more than the surveyor, and that CAD fellow; Man, he scored taking almost the entire project budget.
Even in 1911 engineers were trying to estimate survey budgets? 😏
I want to know: Did the surveyor get paid for the extra work, or did he have to eat the extra?
No, it's probably amount of time spent. I doubt 110 years ago that a surveyor was a highly paid individual. We are far more productive than 40 years ago let alone 110 years ago, yet we don't charge really for that advanced productivity. That's why Smith introduced the bill to make the 32 hour week standard with no reduction in pay.
