The Mechanical Estimation Manager is a senior member of the Pre-Construction function. The postholder will lead the planning and delivery of mechanical tenders across Ireland and Europe, allocate and balance workload across the mechanical estimation team, establish clear tender strategies and maintain consistent estimating standards. The role combines people leadership with hands-on technical and commercial oversight.
Working in partnership with other Estimation Managers, the role will coordinate shared resources, priorities and deadlines across the wider tender portfolio. The postholder will provide clear visibility of capacity, tender status, risks and decisions to the Pre-Construction Director and will ensure that each opportunity has suitable ownership, controls and review gates.
