Addressing Health and Safety During Design
 Form a safety team, including members of design team, owner’s representative,
owner’s risk manager, owner’s insurance carrier (if appropriate), and local
officials
 Identify as many potential risks as possible early in the design process
 Identify stakeholders
 Develop strategies to mitigate risks
 Continue to evaluate risks throughout design process
 Make sure owner understands risks that will need to be mitigated partially or
wholly through training or operational means
 Ensure safety measures are properly commissioned and fully tested
 Where construction will occur at an operational station, ensure contractor is
fully apprised of risks and require that the contractor’s safety plan takes unique
risks into account
