Overview of service

ORS provided civil and structural engineering services for the phased reopening of Galmoy Mine, delivering design from planning through to construction.

Our scope also included the assessment and remediation of the existing 28-metre-high teepee structure, which is being retained as part of the future crushing and screening operations. In addition, ORS delivered engineering services for the dewatering building, River Goul pumphouse restoration works, ore sorting facilities and associated conveyor infrastructure.

The project is located on a 442-hectare site, with the reopened mine expected to produce approximately 310,000 tonnes of ore annually over a 10–12-year operational lifespan. ORS provided engineering services throughout every stage of the project, from design through to construction and ongoing site support.

Challenges & Solutions

The project presented a number of technical and logistical challenges associated with working on a brownfield mining site. Existing infrastructure, unknown ground conditions and ongoing site operations required careful planning to safely integrate new works while maintaining critical dewatering and redevelopment activities.

ORS addressed these challenges through close collaboration with the client, contractors and specialist equipment suppliers throughout both the design and construction phases. Early engagement and ongoing coordination enabled design solutions to evolve alongside construction, helping to maintain programme certainty and minimise disruption.

Innovative techniques, including 3D laser scanning of existing structures, were used to develop accurate structural models for assessment and retrofit design. Combined with a flexible, site-responsive engineering approach, this improved buildability, reduced programme risk and increased confidence in the retention of existing infrastructure.
