The concrete foreman has charge of all concreting operations; the reinforcing foreman has charge of the placing all reinforcing; and the carpenter foreman has charge of the building of the forms and erecting of all staging and hoist towers necessary for carrying on the concreting operations.
Generally speaking, the foremen gain their training from experience and study; night schools have been started in some of the cities of the country, which are giving courses in concrete work, particularly for the man who is anxious to better his position.
PLAN No. 1165. FINISHERS
The repairing of imperfections in the concrete surfaces and the finishing or floating of flat surfaces requires the work of the finisher. He must possess manual dexterity so that he can handle a float skillfully and must know when a surface has been worked sufficiently. Skill is also required in pointing up or repairing imperfections in surface from which forms have been removed. His wages range from 50 to 60 cents per hour. His training is received on the job.
PLAN No. 1166. MIXER OPERATOR
Several things are required of a mixer operator. First he must have some mechanical skill and be able to handle and to take care of a steam or gas engine or an electric motor. He should be able to repair the mixer in case of a breakdown. He must also know something of proportioning and of consistencies required for different mixtures and under different conditions. Wherever any considerable amount of concreting is done the services of a mixer operator are required. The wages are practically the same as for finishers. His training is gained through experience on the job.
PLAN No. 1167. FORM BUILDERS
Form builders are carpenters and must have the experience and training required in that trade.
PLAN No. 1168. REINFORCING PLACERS
Reinforcing placers are very often laborers under the direction of a skilled foreman. Their duties are to place the reinforcing steel according to the specifications prepared by the engineer. In some of the larger cities the Structural Steel Workers’ Union requires that all placing of reinforcing be done by men from their union. The wages vary according to locality. Very little training or experience is necessary.
