We offer effective management of public utility conflicts and relocations of services. This is an element present in many of our projects.

Risk Assessments

Based on AS4360, Harrison Infrastructure Group adopts a straight forward approach to risk management. We have the expertise to deliver risk management strategies - from broad strategic risks to detailed project risks. We work with the client and their project team to establish the context of risks, identify potential risks, analyse the agreed risks, evaluate and rank the risks, develop risk mitigation strategies and manage the ongoing monitoring of the risks. To ensure the risk management strategies are effective, we regularly review the outcomes of the mitigation strategies and determine whether any new risks are likely to appear. This is completed in an environment of effective communication and consultation with those who are best equipped to provide input into the risk management process.
