• Creating contractual project briefs and reviewing and collating pre-construction information.
• Identifying, analysing, mitigating project risks and realising opportunities to enable scope definition and robust pricing by contractors.
• Reviewing preconstruction surveys, drawings, and proposals from our contractors & raising concerns to your senior & lead engineers.
• Assuring the detailed design is undertaken by contractors and any design changes during construction.
• Be responsible for providing the Project Teams with the support they need during commissioning and asset handover.
