Field modifications and repairs: Risk questions to answer early — RiverTruss educational resource

Why this matters

A truss modification or repair must be evaluated by the responsible design professional; visual similarity is not a safe basis for a field fix. Risk work is most useful before money, schedule, or reputation is committed; the goal is to make uncertainty visible while options remain.

Cutting, drilling, or scabbing without an approved detail can change forces and void the intended design.

A practical framework

  1. stop and document the condition
  2. identify the affected member and load path
  3. contact the manufacturer or design professional
  4. retain the approved repair detail and inspection record

Questions to answer

  • What is the earliest warning sign that this plan is moving off course?
  • Which risk is outside the team’s control and needs an alternate path?
  • What evidence would change the recommendation?

Common failure modes

  • Calling a risk ‘unlikely’ without explaining the impact if it occurs.
  • Combining unrelated risks into one vague status label.
  • Failing to revisit the risk register when the scope changes.
