BHM’s foundation assessment and testing process include overseeing the entire construction of deep, shallow and underpinning. A comprehensive understanding of geotechnical engineering and analyzing ground conditions is a prerequisite for construction of the foundation. Foundation assessment is commonly used in regards to soil solidity in instances where the footing of construction may be affected or it can be a complete inspection that may look into various issues that would affect the subsurface of a property. Foundation assessments can provide information on allowable bearing capacity and lateral bearing capacity.
Foundation inspections are necessary in establishing the bearing capacity of the soil affecting the footings of an assigned project. When a site is evaluated for development, proper assessment is needed. The primary concern is foundation and how carefully designing the foundation of the building matters.
When performing foundation assessment, the major concern is how to design the building’s foundation. By using a drilling rig to perform the soil boring and a split spoon sampler is used to collect the soil samples. Foundation assessment in Sydney from BHM geotechnical will help clients to get a comprehensive report.
Shallow Foundations
- Pad footing
- Pile footing
- Trench foundations
- Raft Foundations
- Stepped foundations
Deep foundation
A lot of things get involved in deep foundation including drilling, pile driving, recording the depths/ lengths. Foundation Inspections in Sydney from BHM geotechnical provide clients with the assurance the piles are been constructed to the design specifications.
Pile Driving Analyzer (PDA)
BHM’s foundation process includes Pile Driving Analyzer (PDA). This system calculates shaft integrity, hammer energy, driving stresses while monitoring pile installation. The system will also be used to evaluate the load capacity of existing piles.
Underpinning
It might be an existing construction project or renovation, underpinning is required.
Classify the Lithology
By collecting the soil and rock samples from different depth intervals, geotechnical engineers work on it and determine to start the construction. The soil boring process from the surface to the water table will be anywhere from 2 to 30 metres deep to collect the samples. This would help obtain complete details of the geology and lithology of the site.
