  • Sound commercial and financial acumen, including experience assessing project risks, contingencies, assumptions and cost drivers.
  • Strong understanding of estimating methodologies, benchmarking practices and industry standards, including AACE or equivalent frameworks.
  • Proven ability to work autonomously while building effective relationships with project teams, engineers, contractors, suppliers and key stakeholders.
