Resource Stewardship in Supply Chain: reduced materials in placement using shotcrete
Financial Stewardship: speed of construction
This large, mixed-use development project had an extremely tight construction schedule—the contractor had to place walls very quickly. As shown in Fig.1, shotcrete provided the solution: walls used one-sided formwork, shotcrete was applied, and then the free surface was finished by hand. Forms were then moved to the next wall and reused. With a trailer pump on site twice a week, between 80 and 130 yd3 (61 and 99 m3) of concrete could be shot in an average 8- to 10-hour day.
