The utility trench worksheet shows a straight trench is 135 feet long and access points must be within 25 feet of workers. What minimum number of access points is needed?
Correct Answer
A) 7 points.
One hundred thirty-five feet divided by 25 feet is 5.4 spaces; round up to 6 spaces, which requires 7 access points.
Why This Is the Correct Answer
One hundred thirty-five feet divided by 25 feet is 5.4 spaces; round up to 6 spaces, which requires 7 access points.
Why the Other Options Are Wrong
Option B: 6 points total.
6 points total. is below the supported result for excavation access calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 8 access points.
8 access points. is above the supported result for excavation access calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 9 ladder points.
9 ladder points. is above the supported result for excavation access calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
