n Civil Engineering = Siviele Ingenieurswese - Blasting for construction some critical aspects : construction and project management




When rock blasting is required for construction projects, the technique has a critical influence on overall project progress and costs. Lack of understanding of the discipline leads to unfortunate outcomes, either through excessive constraints on the operation, or else the adoption of cheap, inappropriate technology. In general, blasting systems used for mining are inappropriate for tight control of breaking, and for protection of sensitive structures. In addition, the general inability on a construction site to permit frequent or large-scale blasting operations limits productivity and asset utilisation relative to the volume of rock. Further, the tendency to specify "ultra-safe" vibration limits for blasting, results in unnecessarily slow and expensive progress.
