A fresh set every day. Short, practical, and written the way it actually matters on site.
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.
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.
Shrinkage
Volume reduction as concrete loses moisture over time.
On siteRestrained shrinkage cracks. This is why slabs get control joints rather than being poured monolithic.
Cube Test
Crushing cured cubes to confirm compressive strength.
On siteStandard at 7 and 28 days in India. The 7-day result is roughly two-thirds of the 28-day value.
Benchmark
A fixed reference point of known reduced level.
On siteEvery level on a project ties back to it. Losing or disturbing the benchmark corrupts the whole site.
