The Civil Construction

Manager – Concrete is responsible for the planning, coordination and execution of major civil and structural concrete activities within a nuclear construction environment. The role provides leadership across field execution, subcontractor management, engineering coordination, quality, safety, scheduling and turnover. The successful candidate will bring extensive experience delivering complex concrete scopes and will ensure work is executed safely, efficiently and in accordance with project drawings, specifications, quality requirements and construction schedules.





Lead the planning and execution of civil and structural concrete construction activities, including foundations, slabs, walls, equipment foundations and other major concrete structures. Provide overall leadership for concrete construction activities from pre-construction and constructability review through execution, inspection and turnover. Coordinate concrete activities including excavation interfaces, formwork, reinforcing steel, embeds, anchor bolts, concrete placement, curing, finishing and testing.

Review construction drawings, specifications and work packages to identify constructability concerns, sequencing requirements and potential field constraints. Work closely with Engineering to resolve technical issues, RFIs, drawing discrepancies and field conditions. Coordinate with Quality to ensure work is completed in accordance with applicable inspection and test plans, hold/witness points, inspection requirements and project quality documentation.

Ensure required inspections and approvals are completed prior to concrete placement. Lead short- and medium-term construction planning, including look-ahead schedules, manpower requirements, equipment needs, material availability and subcontractor activities. Monitor field productivity and construction progress and proactively address issues that could impact project milestones.
