Specialist Scaffold Access for a Century-Old Landmark

When TPL Access was engaged to provide scaffolding for the restoration of the University of Auckland’s iconic ClockTower, the team faced a complex engineering challenge. The 54-metre-high landmark, originally completed in 1926, required extensive stone repairs and replastering to preserve its distinctive Gothic architecture ahead of its centenary.

As a Category 1 historic place, protecting the building’s delicate heritage features was essential. Traditional scaffold fixing methods were not suitable, as the scaffold could not be anchored directly to the historic stonework.

Using Layher’s Allround Lightweight Scaffolding System, TPL Access developed a highly specialised, self-supporting access solution that provided safe working platforms at multiple levels while protecting the building’s historic fabric.

Innovative Allround Lightweight Solution

The ClockTower’s intricate Gothic architecture presented significant challenges, with decorative pinnacles, parapets, projecting stonework and varying building profiles requiring a carefully engineered scaffold design.

Layher’s Allround Lightweight Scaffolding provided the versatility and structural performance needed to accommodate these complex architectural features. Its modular design allowed TPL Access to configure the scaffold around the tower’s unique geometry, creating secure working platforms without relying on conventional ties fixed into the building.

Manufactured from high-tensile steel, Allround Lightweight combines reduced component weight with high load-bearing capacity, helping minimise the overall weight of the scaffold while maintaining the strength and stability required for demanding access applications.

The system’s flexible connection options also enabled TPL Access to adapt the scaffold to the tower’s projecting details and varying elevations, providing restoration specialists with access to otherwise difficult-to-reach areas.

Protecting Heritage Through Specialist Access

The restoration involved extensive repairs to the ClockTower’s exterior, including the conservation of deteriorating plaster, stonework and decorative architectural features.

With the building’s heritage significance placing strict limitations on conventional scaffold fixing methods, TPL Access needed a solution that would provide safe and reliable access without compromising the original structure.

The combination of Layher Allround Lightweight’s modular versatility and TPL Access’s technical expertise enabled the team to create a self-supporting scaffold that accommodated the building’s complex architecture while maintaining separation from sensitive heritage surfaces.

The scaffold provided access for restoration specialists to undertake repairs and replastering around intricate ornamental features, supporting the careful preservation of the ClockTower’s historic character.

Preserving an Auckland Landmark

Originally opened in March 1926, the University of Auckland’s ClockTower is one of the city’s most recognisable architectural landmarks and an important part of the University’s identity.

The extensive restoration works were undertaken ahead of the building’s centenary, ensuring its distinctive Gothic architecture could be preserved for future generations.

The innovative self-supporting scaffold design has also been recognised by the University of Auckland as an outstanding example of temporary engineering, highlighting the complexity and technical consideration involved in protecting this historic structure.

The project demonstrates how Layher’s Allround Lightweight Scaffolding System can be adapted to overcome demanding heritage access challenges, combining structural performance, flexibility and lightweight components to deliver practical solutions for complex projects.

For TPL Access, the ClockTower restoration reflects a commitment to careful planning, specialist engineering and skilled workmanship, helping preserve one of Auckland’s most significant historic landmarks.
