The surveying production rate in km per hour is equal to the number of stakes the crew sets per hour divided by the number of stakes required per km. Example: A survey crew is setting 300 stakes per km at a rate of 15 stakes per hour. The cost of a survey crew including transport is 10 per hr. P = 15/300 = .05 km/hr UC = 10/.05 = 200/km Clearing and Piling. The clearing and piling cost ...
