O’Halloran & O’Brien specialises in complex structural refurbishment and alteration works within existing buildings.
Our experience spans the full range of cut and carve operations - from structural modifications and strengthening to partial demolition and reconfiguration of live environments. We combine technical expertise, careful planning and robust temporary works design to deliver challenging refurbishments safely, efficiently and to the highest quality standards.
We undertake major structural changes including core removal, new openings, transfer structures and the installation of new RC elements to support revised layouts and loading requirements.
Our in-house Digital and Construction Engineering Team supports every stage of planning and delivery, ensuring stability and safety where existing structures are retained or modified. Through close collaboration with engineers and clients, we manage each phase with precision and control.
Many of our refurbishment projects take place in operational or historically sensitive settings. We apply strict environmental controls, careful phasing and minimal-disruption methodologies to protect existing assets while delivering modern functionality and compliance.
O’Halloran & O’Brien’s refurbishment capability brings together the technical discipline of our frame and groundworks divisions with the adaptability required for complex existing structures. Our approach prioritises safety, buildability and client confidence — ensuring every project is delivered with the precision that cut and carve refurbishment demands.
