  4. Shrinkage: Reduction in volume caused by water moving out of the concrete porous body
  5. CC: Concrete cover – This is the distance between the concrete surface and the embedded outer layer of reinforced steel
  6. Ast: Area of the steel in tension
  7. R.C.: Reinforced concrete
  8. R.C.C.: Reinforced Cement Concrete
  9. M.O.I.: Moment of inertia
  10. N.A.: Neutral Axis
  11. U.L.S.: Ultimate Limited State – A state where the design is loaded to its breaking point
  12. S.L.S.: Service Limit State – State of design at which the structure is expected to behave under normal conditions
  13. ERSB: Equivalent rectangular stress block – Is a method of designing concrete beams
  14. P.C.: Precast Concrete

9 Common Surveying Terms & Abbreviations

  1. Datum: A reference point with a known coordinate (such as sea level) used as a starting point to determine design level and distances
  2. R.L.: Reduced Level – A point below or above the datum found from surveying operations to determine the design level
  3. B.M.: Benchmark – Height above datum that is recorded by authoritative personnel and founded on places unlikely to move and serve as a reference point
  4. Change Point: A point at which two readings are taken on the staff; those readings reference the height before and after changing the level location
  5. B.S.: Backsight – This is the first reading taken by the surveyor after setting the level and is taken from a benchmark or change point
  6. I.S.: Intermediate sight – Intermediate point or points between the B.S. and F.S.
  7. F.S.: Foresight – This is the last reading taken by the surveyor
  8. Azimuth: This is a horizontal angle used as a reference angle for the theodolite and is always measured in a clockwise direction
  9. Chainage: Imaginary line the measure distances
