The price of survival in the competitive field of construction is a constant effort to investigate every possible means of achieving better economy on the job. Such was the experience of a Connecticut firm which ran into serious difficulties with the economics of concrete slab construction for a housing project. Initially the slabs were placed by dividing the areas into their sections and employing screed supports which required carpenters an average of one to one and a half hours per unit to install. Because this method proved unsatisfactory, the contractor investigated the possibility of using a vibration screed. Since the screed rollers for this unit could ride on the concrete sidewalls, the need for screed supports was eliminated. The contractor on this project also reports that there was an additional time savings which resulted from the fact that the slab could be accurately held to grade when the vibration screed was used. In consequence of this, there was substantial savings in carpenter labor for setting up room partitions.
