Foundation excavation involves the removal of earth to prepare for the laying of the structural foundation. Before the excavation can begin, the site is laid out using wooden pegs and string to delineate the area to be excavated.
Site Clearance & Preparation
A solid foundation is fundamental to any successful project, and before the foundation excavation can begin, the construction site must be cleared.
Trees and underbrush that interfere with the location of the foundation are removed, and deadwood, stumps, and large rocks are cleared. Tree roots are removed at least 30cm below the foundation level, and any pits are filled with soil and compacted.
Factors Affecting the Cost of Foundation Excavations
- Larger and more specialized equipment is associated with higher costs for transportation and fuel.
- While the number of labourers will obviously impact the cost of an excavation, the need for specialists such as surveyors and machine operators is also a factor.
Type of Soil
- Soft soil is the easiest to dig, while stony soil makes the excavation process more complex and potentially more costly as it costs more to dump.
Size of Excavation
- The cost of a foundation excavation will rise depending on the depth of the hole to be dug and the amount of excavated material to be disposed of.
Location of Construction Site
- Additional costs may be incurred for sites that are remote or difficult to access.
- Every project is unique and requires different processes and equipment that will affect the cost of the overall foundation excavation.
