Yes, accurate measurement is essential when you are going to play with a stone wall construction project.
Suppose your accurate wall height is 28 cm. But you mistakenly measured 27 cm. It can decrease the accuracy of your estimates, and you can experience materials shortages during construction.
Similarly, if you measure 30 cm rather than 28 cm, which is the exact one, your waste management expense will increase.
Therefore, accuracy is essential in measurement. Otherwise, you can experience unexpected financial surprises while installing stone walls.
