Complex infrastructure projects that build better communities



Abergeldie designs, and delivers complex infrastructure projects including dams, bridges, tunnels, recreation facilities, water treatment and process facilities, pipelines, rail and mining infrastructure, electrical substations and marine works. Our specialist remediation units rehabilitate degraded civil structures and apply highly specialised technologies to reline degraded pipelines.

Complex projects, large or small, challenge the loyal, professional and multi-disciplined Abergeldie team to “think outside the square”. Ingenuity, innovation and attention to detail are what gives Abergeldie its reputation for quality – meeting and exceeding client expectations again and again. Abergeldie applies the professional engineering and management standards of a major contractor with an open and flexible approach. Adapting to meet the diverse requirements of each client and project is always our priority.
