Abstract:
The U. S. Bureau of Public Roads subjected a number of concrete road construction jobs to detailed analysis in order to ascertain what causes prevented consistent production at a rate theoretically possible, and to discover if these causes of delay were avoidable. The analysis embodied answers to the following questions: What is full production? What causes interfere with it? and, Are they avoidable? Stopwatch studies were made on all minute operations in materials handling and mixing and placing of concrete. As a result of these studies better synchronization of operations was possible, with a material increase in hourly and daily production, and the attainment of a better average. The whole story is told in this paper by Mr. Harrison, highway engineer of the U. S. Bureau of Public Roads.
