"I wanted to take a moment to express my appreciation for the excellent work your team did during the hot-tapping operations in Allanooka. The quality of work and professionalism exhibited by everyone on the team was truly impressive. We were particularly impressed with the care and precision with which all equipment was operated."
P. Lee
Senior Project Manager - Rob Carr"The whole job was exceptionally organised and the teamwork between the crews was seamless. That is the level of preparedness and safety we strive for on all work, especially nightshift. The feedback from the Operations Manager, Communications Advisor, and local customers have all been full of praise for the work."
J. Collier
Project Leader - Water Corporation“Saltire successfully delivered works for the Armadale Line Upgrade Alliance (ALUA), including self-performed Water Corporation relocations for the Beckenham, Cannington, and Wharf Street packages. Saltire demonstrated strong performance, meeting the standards expected on a Tier 1 project.
Despite site complexities and programme challenges, Saltire maintained a strong commitment to safety and delivered the works in alignment with the ALUA schedule.
Saltire’s proactive approach to stakeholder engagement and problem-solving was a key factor in the project’s success. Their flexibility in adapting to evolving site conditions and ability to coordinate efficiently with other contractors contributed significantly to minimising disruptions and ensuring the seamless delivery of critical project milestones.”
S. Doogan
Delivery Manager - Armadale Line Upgrade Alliance“Being unable to carry out our traditional in-house inspections under isolation due to no contingency for supplying over 30,000 homes, we had to look for an alternative solution.
Previously working with Saltire on other projects using other equipment, we were confident the job would be delivered successfully. Working in an environmentally sensitive area and in a complex excavation, the team delivered beyond expectations. Utmost professionalism from scope to delivery”
