A fresh set every day. Short, practical, and written the way it actually matters on site.
Bearing Capacity
The pressure a soil can carry before it fails in shear.
On siteSafe bearing capacity applies a factor of safety, usually 2.5 to 3, to the ultimate value.
Traverse
A connected series of measured lines forming a survey framework.
On siteClosing error reveals accumulated error. A traverse that does not close should never be used to set out.
Consolidation
Gradual settlement as water is squeezed out of saturated fine soil.
On siteIn clay it continues for years. This is why buildings on clay keep settling long after handover.
Permeability
How readily water flows through a soil mass.
On siteDecides whether an excavation needs dewatering and how fast a clay layer will consolidate.
Live Load
Movable, variable loads from occupancy, furniture and people.
On siteIS 875 Part 2 fixes the values by use — residential, office and storage differ sharply.
