BHM offers a comprehensive foundation assessment and testing process that encompasses oversight of the entire construction process for deep, shallow, and underpinning foundations. An in-depth understanding of geotechnical engineering and a thorough analysis of ground conditions are crucial prerequisites for constructing a solid foundation. Foundation assessment is typically used to evaluate soil solidity in cases where the footing of a construction project could be affected, or it may involve a complete inspection that examines various issues that could impact the subsurface of a property. The information obtained from foundation assessments can provide insights into allowable bearing capacity and lateral bearing capacity.
Foundation inspections are essential for determining the bearing capacity of soil that could impact the footings of a given project. When evaluating a site for development, a proper assessment is needed, with the primary focus being on the foundation and the importance of designing it carefully.
When conducting a foundation assessment, the primary consideration is the design of the building’s foundation. The process involves using a drilling rig to perform soil boring, and a split spoon sampler is used to collect soil samples. By obtaining Foundation assessment in Sydney from BHM geotechnical, clients can receive a comprehensive report on their project.
Shallow Foundations
- Pad footing
- Pile footing
- Trench foundations
- Raft Foundations
- Stepped foundations
Deep foundation
The construction of a deep foundation involves various complex processes, such as drilling, pile driving, and recording depths/lengths, which necessitate a thorough and meticulous approach. Foundation Inspections in Sydney from BHM geotechnical provide clients with the assurance that their piles are constructed in compliance with design specifications.
Pile Driving Analyzer (PDA)
BHM’s foundation process includes the use of a Pile Driving Analyser (PDA) system, which calculates shaft integrity, hammer energy, driving stresses while monitoring pile installation. The system is also used to evaluate the load capacity of existing piles.
Underpinning
Underpinning is often required for existing construction projects or renovations.
Classify the Lithology
Geotechnical engineering works to classify the lithology by collecting the soil and rock samples from different depth intervals. The soil boring process can be anywhere from 2 to 30 metres deep, from the surface to the water table, to obtain complete details of the site’s geology and lithology.
