The new Oldbridge 110kV GIS substation will be located withing the DUB062 campus in North County Meath, Ireland.
The substation building consists of an insulated cladded steel portal frame with parapet on all four elevations, a load bearing first floor composite slab on steel frame, gantry girder and crane beam, associated secondary steelwork for ventilation, bracing, and roof/wall cladding supports.
Potential clash issues identified and resolved
All four elevations of the building were designed for fire boundary conditions as per the Irish Standard L00146A. Nine different paint specifications were used to identify the elements that required full/partial or no intumescent coating. Extensive IFC coordination between the steel detailing team and the Architect and Structural Engineer was required to identify all areas for each different paint requirement (boxed-out areas, areas encased in concrete). IFC coordination was also used for the 2no RC stair cores located inside the building to correctly locate the areas where additional supporting steelwork was required to be cast-in. Openings in the elevations for ventilation were also coordinated by utilising IFC models which enabled any potential clash issues to be identified and resolved as early as possible.
Important points or benefits:
- Hot rolled tonnage: 220
- Cold rolled tonnage: 12
- Heaviest assembly: 3.5 tonne
- Longest assembly: 14.8m
- UDAs were used to identify completed elements (with colour coding), paint specifications were also applied to each member using UDAs to denote each different type
