Problem 20. Work the following problem to see how well you understand the concept
covered in step 16. The solution to this problem is found at the end of the lesson. Determine
how many wales are required for one side of the form if the wale spacing is 30 inches and the
form is 8 feet high.

Step 17. Determine the time required to place the concrete. Determine the time required to
place the concrete by dividing the height of the form by the rate of placing (step 4). Round all
answers up to the next full hour. For example, for 3.6, use 4 hours; for 5.8, use 6 hours; or for
2.1, use 3 hours. Compute as follows:
form height (ft)
Time to place concrete (hr) =
