Overview of service

Bluebell is a state-of-the-art residential development on the Grand Canal in Dublin. It comprises two substantial buildings.

One is a 9-storey block comprising of 36 apartments at the junction of Kylemore Road and Grand Canal. The second is a 4-storey block of 16 apartments facing the canal. Carparking for 54 cars will be provided at ground level, 48 of which are located underneath the building.

The ORS Fire Safety Team was appointed to provide fire safety and disability access consultancy services for the development.

As part of the scope of work, ORS compiled and submitted all Fire Safety Certificates (FSC) and Disability Access Certificates (DAC) across the scheme. Upon granting the FSC and DAC, the ORS Fire Safety Team also had to ensure that construction proceeded in line with the granted certification and to ensure compliance at every step. This was done by undertaking regular site inspections, providing technical support throughout all project stages, and maintaining consistent communication. ORS also provided liaisons with Building Control, Fire Services, and final BCAR Ancillary Certification.

Project challenges

Managing design changes

During the project’s construction stage, the client made a significant design change to the configuration of the stairs and associated lobbies in the development. The change made the natural ventilation of the stairs and lobby problematic.

This was a challenge for the ORS Fire Safety Team in terms of fire safety compliance. The change triggered a revised fire safety application which ORS prepared on behalf of the client. The solution was for ORS to explore alternative and innovative alternatives with Dublin Fire Brigade. The team proposed a mechanical ventilation solution. Using CFD modelling, ORS demonstrated that the design of the alternative ventilation method was equivalent to a code base design proposal. Dublin Fire Brigade accepted the proposal, and a Fire Safety Certificate was granted.

FSC design calculations included an ‘L shape’ undercroft car park which needed to demonstrate compliance with the Fire Authority for cross ventilation.

The scheme included a mix of conventional brick cavity construction and rain-screen cladding, with elements extending over 18m high and incorporating associated combustibility limitations on insulation. The development incorporated a mechanical smoke ventilation system to protect the common lobbies to the stair. This required a computational fluid dynamics (CFD) to verify the performance of the proposed SVS system and a revised FSC application to approve.
