Phase 1 Works - Conclusion

Fire upgrade works were relatively straightforward

• Occupancy levels were low (34)

• Travel distances were short

• No living accommodation to deal with

13

Works were carried out with minimal intervention to historic fabric

• M&E consultants and contractors embraced the process to think creatively about how to distribute services around the building without creating additional openings, chasing walls or notching joists

• This also reduced the amount of fire stopping required

CITY ASSEMBLY HOUSE

Phase 2 Works

Date: March 2017 – June 2018

Contract Sum: €1m

Scope of Works:

Upgrade the Assembly Room as an art gallery (and performance space) with the vision of recreating the original art exhibition of the 18th Century

Phase 2 Works - Conclusion

Challenging Project

• Invasive work with the installation of the new lift, staircase & new exit

• Building is now fit for public use & is a cultural hub in the city centre

33

BCaR

• Resulted in a higher level of inspection on site.

• It caused delays and stress on site (partly due to unknows in existing buildings. Everything cannot be pre-designed)

• Future programmes should reflect this

• Better and safer building as a result
