Since 1919 the Hydro-Electric Power Commission of Ontario has been applying quality control methods to its concrete work. While the knowledge of quality control could be applied to the big jobs, the scattered small jobs presented a different problem. But by. 1926 jobs as small as 1000 cu yd had been done using a modified control technique. From thereon followed rapidly the development of "instructions" for superintendents and foremen on jobs not exceeding 500 cu ft instructions have now been revised in the . ight of more than a decade of experience and are presented by the authors - not as an answer to, but as a contribution toward the solution of the problem of quality control on small jobs. Control methods which the commission finds adequate and workable for its scattered small jobs would have to be altered for general application but these instructlons may,nevertheless, provide a key to the problem of ordlnary concrete.
