Challenge

During construction of a two-storey (G+1) residential development at 1 Patrician Avenue, Naas, Co. Kildare, an on-site constructability issue arose with the original compartment wall specification.

The specification, while compliant with TGD-B, proved onerous to implement on site and risked delaying the project or increasing costs if left unresolved. SOCOTEC Ireland was appointed by Corgan to provide fire safety consultancy and determine a route to full compliance.

The scope of work required a Revised Fire Safety Certificate (RFSC) application to Kildare County Council, addressing the practical challenges encountered during construction while ensuring the building continued to meet TGD-B requirements.

Project Description and Background

Patrician Avenue

SOCOTEC was appointed by Corgan to support the residential development at 1 Patrician Avenue, Naas, a two-storey building comprising apartments with independently accessed entrances.

The original design had received fire safety certification, but on-site conditions during construction highlighted the need to revisit the compartment wall specification governing escape provisions for the ground-floor Apartment 01 and first-floor Apartment 02.

Given the independent access arrangements already built into the scheme, the brief was to develop a revised fire safety strategy that resolved the constructability issue while preserving the building's compliance status and its intended layout, all within a timeframe that would not disrupt the construction programme.

Solution

Patrician Avenue

SOCOTEC prepared a Revised Fire Safety Certificate Application Compliance Report directly addressing the on-site constructability issues identified with the original compartment wall specification.

Supporting the report, five drawings were produced covering the site location, layout, floor plans, elevations and section, and the attic and roof plans, all prepared in AutoCAD and issued in PDF format overlaying the existing DWG files to ensure consistency with the as-built design. The revised strategy removed the protected entrance halls from the ground-floor Apartment 01 and the first-floor Apartment 02, along with the protected stairway serving the first floor, and introduced escape windows from habitable rooms as an alternative means of escape.

Throughout, independent access arrangements for both apartments were maintained, with no shared egress routes introduced as a result of the changes. The completed application, including the compliance report and drawings, was lodged with Kildare County Council via the BCMS online portal, allowing the revised strategy to be formally assessed and approved without requiring redesign of the building's core layout.

Conclusion

The revised fire safety strategy enabled on-site construction to proceed without significant delay and avoided the cost escalation that would have resulted from retaining the original compartment wall specification.

The streamlined escape window solution maintained full regulatory compliance under TGD-B, and the accompanying technical report demonstrated that the proposed changes introduced no new or greater contravention.

By accommodating the practical realities of the construction phase, SOCOTEC delivered a swift RFSC turnaround that directly supported the project's completion timeline.
