What is the number of wall logs required to construct a rectangular log crib using the post offset design given the roadway width equals 30 feet and the average tree diameter equals 12 inches?

Answer 1

To determine the number of wall logs required for a rectangular log crib using the post offset design, first calculate the perimeter of the crib based on the roadway width. For a 30-foot width, assuming the crib is rectangular, the total perimeter would be 2 times the width plus 2 times the length, which needs to be defined. Given the average tree diameter of 12 inches (1 foot), you would typically use one log per foot of perimeter; thus, if the total perimeter is known, divide it by the log length to find the number of logs needed. If the exact dimensions of the crib are provided, a more precise number can be calculated.
