Key Learning Outcomes

For construction professionals:

  • It is good practice to carry out a risk assessment and method statement (RAMS) for all construction activities. This can ensure the sequencing of work activities are carefully considered, planned and temporary works provided if necessary.

  • Regular toolbox talks are a good way of engaging with work crews and highlighting any risks associated with work activities

For civil and structural design engineers:

  • Careful consideration is required for the design of masonry walls, particularly in the temporary stage because there is no redundancy and relatively small loads at the tip can precipitate failure

  • If a masonry wall relies on support from an adjacent wall in the permanent condition, highlight this on the drawings to bring it to the contractor’s attention

  • Any temporary work issues or requirements should be highlighted in risk registers and on construction drawings
