The 4 August 2026 council decision follows the 13 July heritage/ecology submission; Commission case 501898 is pending after lodging on 17 August. The original November drainage design and the separate wildlife-licence window remain explicitly dated.
The event-centre decision is under appeal
Council decision under appeal; implementation not established · Limerick 2561246; event centre and separate existing outbuilding refurbishment
What the evidence says
The council notified a decision to grant on 4 August 2026 after further information received on 13 July. The decision describes an approximately 1,460 m² event centre and separate refurbishment of the existing 22 m² Building 12, within the Roche Castle setting. Commission case 501898 records an appeal lodged on 17 August and no decision. This is a staff event and training facility on the existing campus, not a new pharmaceutical production building or a final grant.
Why it may matter — interpretation
Interpretation: keeps the current consent stage and work package distinct from the wider production campus.
What is not established
The appeal outcome, final grant, commencement and completed floor area remain unverified.

The original design names AquaCell NG or equivalent
Source-specific proposal; final detail and implementation unverified · November Issue A design for the event-centre drainage; two location-specific tanks
What the evidence says
The November infrastructure report specifies two soakaway tanks: a stated 55 m³ beneath the car park and 83 m³ beneath the adjoining green area. Its calculation basis is Wavin AquaCell NG or equivalent with permeable geotextile and 96% void space. These are separate stated design volumes and an example product basis, not an order or a verified installed capacity. The report predates the July heritage and ecology response; the complete later drawing set has not been reconciled.
Why it may matter — interpretation
Interpretation: retains a useful named drainage system without turning an equivalent specification into a selected supplier.
What is not established
Final tank geometry, hydraulic acceptance, chosen product and installed volumes are unverified.

The proposal keeps this roof runoff out of the canal
Source-specific proposal; final detail and implementation unverified · Event-centre and courtyard roof catchment; wider campus drainage excluded
What the evidence says
The infrastructure report proposes gutters and downpipes to the existing courtyard roofs and the new event-centre roof, feeding a dedicated infiltration network. The scheme includes 225–300 mm twinwall carrier pipes, gullies, channels and permeable paving. Both the original report and the August decision describe two soakaways and no discharge from this building to the Loughmore Canal. This is the specified route for this package, not a claim about all campus drainage or proven discharge performance.
Why it may matter — interpretation
Interpretation: explains how the existing roofs and new works connect to a defined civil-engineering package.
What is not established
Later detailed pipe layouts, site testing, installed network and actual discharge performance are unverified.

Foul drainage connects to the existing campus pumping system
Source-specific proposal; final detail and implementation unverified · November proposed event-centre foul network and existing private pump chamber
What the evidence says
The November report proposes mainly 150 mm gravity foul drainage serving three vendor units, a breakroom and two toilet areas. It connects to an existing foul pump chamber, with a macerator added to the existing pumps. The report does not propose a new direct public-sewer discharge for this development. This is an interface with the campus system, not a new standalone treatment plant.
Why it may matter — interpretation
Interpretation: identifies the specific pump and drainage interface without expanding it to the entire campus.
What is not established
Final pump duty, macerator model, approved detailed design and commissioning are unverified.

The decision requires a salvage catalogue and conservation oversight
Council decision under appeal; implementation not established · Council conditions 3 and 4; protected courtyard buildings and their interfaces
What the evidence says
Condition 3 requires a catalogue of salvaged fabric and features placed in storage for potential reuse, with an alternative strategy if reuse within the site is unlikely. Condition 4 requires qualified architectural-conservation supervision and a completion record. The July response had addressed doors and windows, mechanical and electrical routes, and the new-to-existing roof connection. A catalogue requirement does not establish that each stored item will be reused.
Why it may matter — interpretation
Interpretation: shows the conservation and reuse obligations attached to the works.
What is not established
The final item-by-item reuse destinations, completed conservation works and compliance submission are not verified.

The submitted wildlife licence has a separate end date
Source-specific proposal; final detail and implementation unverified · Submitted NPWS licence conditions; separate statutory permission and timing
What the evidence says
The July submission contains a wildlife derogation signed on 8 July 2026. Its conditions limit the authorised actions to 8 July–31 December 2026, require ecological supervision, and expressly prevent works under it before planning permission is granted. That ecological permission is separate from the pending planning appeal; it is not evidence that construction is authorised now or that the licence window will be extended.
Why it may matter — interpretation
Interpretation: keeps an expiry-sensitive enabling permission separate from the planning decision.
What is not established
A later licence extension, final planning permission and completed authorised actions have not been established.

Selected pages of 3 government-published PDFs were visually inspected. Fifty-four council index rows were retained. Selected pages of three supporting PDFs were visually inspected; a fourth downloaded planning report was text-screened only. The first of four files in the further-information submission was inspected, not the entire submission or all hydraulic appendices. Proposals do not establish procurement or installed work.
