You will work as part of an OrmoInfra team or be embedded directly within one of our clients' project teams. Depending on your experience and the assignment, your responsibilities may include contract administration and commercial management, procurement and subcontractor engagement, preparation and assessment of variations, cost forecasting and cost reporting, subcontractor payment assessments, contractual correspondence, claims preparation and assessment, tender and bid evaluation, quantity take-offs and measurement, cost estimating and benchmarking, commercial risk identification, final accounts and contract close-out, and supporting Project Directors and Commercial Directors with commercial decision-making. This is not a traditional consultancy role focused on producing reports from outside the project.
