The Grenfell Tower tragedy of 2017 was a wake-up call that reshaped building safety regulations in the UK. The Building Safety Act of 2022 ushered in sweeping changes, emphasising the urgent need for safer cladding on high-rise buildings. As the demand for recladding projects surges, the need for efficient temporary access systems has never been greater. System scaffolding emerges as a game-changer in this crucial area, offering significant advantages over traditional methods.

Why focus on recladding?

Recladding projects are vital for addressing fire safety risks posed by unsafe cladding materials. The swift and efficient execution of these projects is crucial not only for contractor efficiency but also for minimising disruption to residents. With numerous high-rise buildings still awaiting remediation and more unsafe structures being identified, the right temporary access systems are essential for expediting these projects.

Scaffolding vs. Mast climbers

When it comes to replacing cladding, access to the building’s facade is key. Scaffolding is often the preferred choice due to its ability to accommodate multiple trades working simultaneously and its resilience against weather conditions. Mast climbing carry much heavier loads than traditional scaffolding and are used to position personnel and the necessary tools, equipment, and materials needed to perform work at great heights. Mast climbers, while beneficial for modern facades, are less suited for older buildings with EPS (Expanded Polystyrene (EPS) foam) cladding, which can be problematic in windy conditions and requires power sources.

Mast climbers also face limitations at lower heights, making them less effective without scaffolding for complete access. Scaffolding provides comprehensive access, including protection for public areas, and offers better control over debris and falling objects through protective sheeting.

The right scaffolding matters

The traditional scaffolding method involves wrapping an entire building, which can obstruct windows and affect residents’ natural light exposure. Prolonged lack of natural light can negatively impact mental health, making it essential to minimise disruption. With some recladding projects extending up to two years, the efficiency of scaffolding systems is crucial.

System scaffolding offers a solution to these challenges. Unlike traditional methods that rely on timber boards, system scaffolding uses modular components that are quicker to install and remove. These modern systems, such as PERI UP, feature built-in safety components and advanced guardrails, reducing the time and labour required for setup. System scaffolding is also made from non-combustible materials, enhancing safety and addressing the fire risk concerns associated with timber.

The PERI UP scaffolding system is a modular scaffolding system developed by the German company PERI. It is designed for use in various construction applications, providing a flexible and safe solution for access and support. Overall, the PERI UP scaffolding system is known for its robustness, flexibility, and safety, making it a popular choice in the construction industry.

Streamlining the process

System scaffolding facilitates faster installation and dismantling. For instance, on The Link, a high-rise building in London, system scaffolding reduced installation time from 16 weeks to just four weeks—a 75% improvement. This speed not only shortens project timelines but also lessens the impact on residents and reduces overall costs.

The investment payoff

Investing in system scaffolding presents long-term benefits for recladding projects. With careful planning and proper training, contractors can achieve significant time and cost savings, while improving safety and reducing disruptions. In the wake of Grenfell, optimising the recladding process is more important than ever, making system scaffolding a crucial tool in advancing building safety and efficiency.
