A fresh set every day. Short, practical, and written the way it actually matters on site.
Reduced Level
The height of a point above the chosen datum.
On siteEvery foundation depth, plinth and floor level on a drawing is expressed as an RL.
Curing
Keeping concrete moist and at a stable temperature while it gains strength.
On siteStopping curing early can cost 30% or more of the design strength. It is free and routinely skipped.
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.
Angle of Repose
The steepest natural slope loose material holds without sliding.
On siteIt governs safe excavation batter. Cutting steeper than this is how trench collapses kill people.
Bending Moment
Internal moment causing a member to curve.
On siteMaximum at midspan for a simply supported beam, and at supports for a continuous one.
