Construction of a rubble mound in exposed conditions is usually limited by

  • A.the price of the concrete used in the crown wall
  • B.the depth of water at the site during low tide
  • C.the weather windows available for marine plant to work
  • D.the availability of skilled labour in the local region

Answer: C

Partly built structures are far more vulnerable than completed ones to a storm. Construction risk is managed by sequencing the work so that the exposed states are as brief as possible. Sequencing is part of the design, not an afterthought.
