Consider the following statements about breakwater maintenance.
1. Early repair of local damage prevents progressive failure.
2. Regular survey identifies damage before it becomes serious.
3. Repair is best deferred until damage is extensive.

  • A.1 only
  • B.All of them
  • C.1 and 2 only
  • D.3 only

Answer: C

The first two are correct and are the basis of asset management. The third is false economy, since damage accelerates once the armour layer is breached. Early repair is far cheaper than late repair. Deferral converts maintenance into reconstruction.
