Motion Study
A Method for Increasing the Efficiency of the Workman

44 MOTION STUDY and placed upon the wall in units as large as could be economically handled. 4. The bricklayer could not be expected to do away with those motions that are necessary to remove the lumps from under a brick if there were holes in the sand screen and no pug mill to break up the lumps. It is most important that the workman should be given “handy conditions” under which to work, that is, the “most comfortable,” or those that require the ‘‘least per- centage of rest” to overcome fatigue. Examples. — 1. The bricklayer must obviously have a scaffold to stand upon that permits adjusting the height of the platform on which he stands to a standard distance below the top of the ever-growing wall on which he is lay- ing the brick. We have found that the best height is from twenty-four to thirty-two inches below the top of the wall. If the wall is being laid overhanded, the height should not be over twenty-four inches, while if the wall is not being laid overhanded, thirty-two inches is the better height. It is obvious that the bench from which the stock is picked up should be maintained at a standard distance above the platform on which the man stands. Also the platform on which the laborer walks should be located at the standard distance below the stock platform that will enable him to deposit the brick and mortar in a manner that will cause the least fatigue. Therefore, the three platforms for bricklayer, stock, and tender should be
