Southern Demolition was engaged by Lincoln University to undertake the demolition of the iconic Burns Building, one of the University’s most recognisable landmarks. Officially opened by the Minister of Education in 1976, the Burns Building was named in honour of Sir Malcolm Burns, who served as Principal of Canterbury Agricultural College from 1952 to 1974 and was a Senior Lecturer in Soil Science between 1937 and 1948. For nearly five decades, the building played a significant role in the University’s history, making its demolition a carefully planned and highly significant project.

The project was completed over an 11-month period from October 2023 to September 2024. Works commenced with the safe removal of asbestos-containing materials, followed by a comprehensive interior soft strip to remove non-structural building components and prepare the structure for demolition. The final stage involved the controlled demolition of the eight-storey reinforced concrete building using a high-reach excavator, supported by a fleet of specialist demolition equipment and experienced personnel.

Given the building’s central location within an active university campus, environmental management was a key priority throughout the project. Southern Demolition implemented extensive dust suppression measures using high-capacity dust cannons, while continuous noise and vibration monitoring technology ensured demolition activities remained within strict environmental limits. These controls helped minimise disruption to students, staff, neighbouring properties and the wider public while maintaining a safe working environment throughout the duration of the works.

Sustainability was a major focus of the project. Rather than transporting demolition materials off site for disposal, Southern Demolition processed the reinforced concrete on site using mobile crushing equipment. Approximately 6,000 tonnes of recycled concrete aggregate will be reused by Lincoln University in future campus developments, with the remaining material allocated to infrastructure and construction projects throughout the Canterbury and Selwyn districts.

By recovering and recycling the building’s concrete, Southern Demolition successfully diverted thousands of tonnes of material from landfill while significantly reducing the demand for newly quarried aggregates. This approach not only minimised the environmental impact of the demolition but also contributed to a more circular construction economy, ensuring the legacy of the Burns Building continues through its reuse in future projects across the region.
