“This was a challenging project to deliver on time, within budget, safely and with the minimum of disruption. Especially during the Pandemic. The onsite Sprinkler Installers / Pipe fitters were very respectful of the tenants / occupants and were faultless in their delivery throughout the entire project which was Phased over 4 years. Many thanks for accomplishing all those challenges as well as improving the safety of all the Casa Farnese Building tenants / occupants.”
