Proposed 110 kV Substation at a site fronting onto Steeven’s Lane, Dublin 8
Verify against official sourceReviewed build intelligence
What the documents propose
Direct application pending
Application-stage technical proposals. No permission, construction contract, product purchase or installed specification is established by the inspected files.
2 official documents inspected · Checked 2026-09-05 · Official file index
Brick boundary and anthracite cladding
Proposed in application · Substation building and Steeven’s Lane frontage
What the evidence says
The design proposes a concrete plinth, dark anthracite metal composite panels to the GIS building, and a red-brick boundary wall. Its orange/red/yellow brick palette uses champagne-coloured mortar, recessed and projecting work, and vertical/horizontal brick orientations.
Substation building and Steeven’s Lane frontage
Why it may matter — interpretation
Interpretation: identifies a defined envelope and specialist brickwork package.
What is not established
No brick manufacturer, final sample approval, cladding supplier or construction appointment is evidenced.

Defined GIS bay requirement
Proposed in application · Steeven’s Lane GIS building; bays are equipment counts, not homes or separate development units
What the evidence says
The design statement says the building must accommodate eight 110 kV GIS bays and fourteen MV GIS bays, with an overhead maintenance crane and cable bend-radius clearances shaping its height.
Steeven’s Lane GIS building; bays are equipment counts, not homes or separate development units
Why it may matter — interpretation
Interpretation: useful for electrical equipment, steelwork and installation coordination.
What is not established
No manufacturer or procurement award is identified; these are application requirements.

Transformer containment and oil-control components
Proposed in application · Transformer bays and their drainage
What the evidence says
The engineering report proposes bund capacity of at least 110% of transformer oil volume and a hydrocarbon-detecting pump that stops and alarms on contamination. The drainage drawing labels Entexol SCS001 oil-sensitive dewatering and SCS002 integrated Class 1 full-retention oil separator, each with an equal-and-approved alternative.
Transformer bays and their drainage
Why it may matter — interpretation
Interpretation: identifies oil containment, pumping, alarms and separator specifications for later procurement checks.
What is not established
Named products are proposed reference specifications, not exclusive purchases or installed products; equal-and-approved substitutions remain possible.

Permeable compound with controlled outfall
Proposed in application · Substation compound drainage
What the evidence says
The report proposes permeable asphalt above a 650 mm stone storage layer with 30% porosity and a hydrobrake restricting discharge to 2 litres per second. The compound detail includes an impermeable liner, a 1% crossfall and perforated drains.
Substation compound drainage
Why it may matter — interpretation
Interpretation: points to permeable surfacing, aggregate, lining and flow-control work.
What is not established
Storage performance is a design assertion in the application; construction verification and final drainage agreement are not established.

Lightweight roof and requested green-roof exemption
Proposed in application · GIS building roof; application request
What the evidence says
The appended technical note describes a two-storey steel frame on reinforced-concrete slabs, cold-formed steel roof purlins and insulated metal sandwich panels. It seeks an exemption from green/blue-roof requirements, proposing permeable surfacing instead.
GIS building roof; application request
Why it may matter — interpretation
Interpretation: important for roof, steelwork and drainage scope because the proposal expressly requests an alternative to a green roof.
What is not established
The note is a request, not evidence that the exemption has been granted. Panel brand, insulation thickness and final fire specification are not established.

Remaining document questions
- Which later official decision, approved detail or revision changes these source-specific findings?
- Has a phase-specific official record established the selected equipment or installed specification?
Selected pages of 2 government-published PDFs were visually inspected. Two distinct PDFs, with selected technical pages visually checked. Appended drawings are pages of the engineering PDF, not extra inspected files. Proposals do not establish procurement or installed work.
