Frequently asked questions
What does a construction site investigation include?
A construction site investigation typically includes borehole drilling, test pitting, soil and rock testing, and groundwater assessment. This investigation also involves engineering analysis to support foundation, earthworks, and retaining wall design.
What is included in a geotechnical engineering report?
A geotechnical engineering report provides site conditions, investigation methods, soil and rock profiles, and groundwater observations. It also includes clear engineering recommendations for foundations, earthworks, and construction practices.
How long does geotechnical investigation and testing take?
Geotechnical investigation and testing timelines vary depending on site access and project complexity. Most residential investigations are completed within one to two weeks, including reporting.
Will geotechnical testing identify groundwater issues?
Yes, geotechnical investigations assess groundwater presence, depth, and potential impact on excavation, foundations, and drainage. The findings are clearly documented in the geotechnical engineering report.
Can a geotechnical report be used by builders and engineers?
Absolutely. A professionally prepared geotechnical report for construction is used by structural engineers, civil engineers, builders, and certifiers. It guides design and on-site decisions.
