One of the very first things that need to be done in any construction project is excavation. This is the systematic and careful process of removing earth. In other words, a methodical technique of digging. In construction, excavation refers to the process of hauling and moving dirt, rock, earth or other materials using heavy equipment or even explosives.
Excavation is a technique crucial not only for construction, but also for other disciplines. Other important fields use this process for other purposes such as mining, exploration, or environmental restoration. Techniques commonly used in excavation include digging, dredging, trenching, cut and fill excavation. To optimize these, the proper technologies and machineries are employed.
The entire process of the excavation follows this flow:
– Marking the boundaries and corners to be excavated
– Surveying the ground levels
– Digging, dredging, and trenching as needed to the depth stated in the plan
– Dressing the loose soil
– Making up to the cutoff level
– Formation of wells for runoff water and interconnecting trenches
– Marking building boundaries
– Creation of protection bunds and drains.
