Christ Church Cathedral – Heritage Concrete Condition Assessment

Overview
CQT Services was engaged by Duratec to carry out a concrete condition assessment on part of Christ Church Cathedral, a significant heritage building with concrete more than a century old.

Heritage structures offer a rare chance to see how concrete performs over a very long service life. Our role was to understand how this concrete has performed over the past 100 years, and to give Duratec the specialist advice needed to support the building’s care into the future.

Our approach
Working on a heritage building calls for a careful, considered approach that gathers the right information while respecting the fabric of the structure. Our assessment brought together:

• Specialist site inspections: Our team carried out multiple inspections to build a thorough picture of how the concrete has performed over time.

• Non-destructive testing: This let us assess the concrete across the inspection area without affecting the structure.

• Targeted coring: Carefully selected cores gave us a closer look at the concrete itself.

• Testing, specialist analysis and reporting: Bringing the findings together into clear advice to help manage the structure’s condition and extend its service life.

Together, these gave us a clear, evidence-based understanding of the concrete’s condition.

Looking ahead
Projects like this show how well-built concrete structures can stand the test of time. Understanding how heritage concrete has performed over the past century helps owners and contractors make informed decisions about its future care.

We’re proud to have contributed to the ongoing story of Christ Church Cathedral, and we thank Duratec for the opportunity to be part of it. We look forward to seeing the cathedral standing strong for the next 100 years and beyond.
