  • Risks and mitigation strategies
  • Value engineering opportunities

  • Remain involved in successful projects during the early pre-construction phase, supporting supply chain engagement, cost updates until handover to the project delivery team.
  • Assess and review potential alternative design solutions and equipment options for budget and technical optimisation.

Site Engagement
  • Attend site surveys in Ireland and Europe during estimation period to review project scope.

Requirements & Experience
  • Third level Qualification in Building Services Engineering.
