Tenon Clearwood Roof Replacement

Project Overview

Tenon Clearwood required a comprehensive scaffolding solution to facilitate the asbestos roof replacement at their sawmill facility.

The project involved the construction of gabled ends for a rolling roof using the Layher Keder Roof System. Additional requirements included internal back propping to allow the structure to be built on the roof, internal trusses, and an under-roof to safely contain asbestos.
Throughout the project, it was critical to ensure the sawmill remained fully operational without disruption.

Scaffolding Requirements

• Construction of loading bays on the gable end using the Keder Roof System.
• Internal back propping to support structural integrity.
• Installation of internal trusses and an under-roof for asbestos containment.
• Bridging structures to enhance roof support.
• Compliance with health and safety regulations, including SARNZ, Site Safe, and TDDA certification.
• Seamless integration with sawmill operations to minimize disruptions.

Design Merit

Innovation: The use of the Keder Roof System provided a lightweight yet robust solution, allowing for efficient assembly and disassembly.
Engineering Excellence: Internal trusses and back propping were strategically designed to stabilize the deteriorating roof structure.
Architectural Integration: The scaffolding design was tailored to accommodate the building’s unique requirements without obstructing ongoing operations.
Safety Measures: The under-roof system effectively contained asbestos, ensuring a safe working environment.

Project Challenges

Operational Continuity: Ensuring minimal disruption to sawmill operations while erecting and dismantling scaffolding.
Structural Deterioration: Addressing the compromised roof structure with precise scaffolding solutions.
Environmental Factors: Designing scaffolding to withstand wind, rain, and temperature fluctuations.
Asbestos Management: Implementing safety measures to contain hazardous materials effectively.

Environmental Impact Awareness

Optimized Transportation: Local suppliers were utilized to reduce emissions and transportation costs.
Material Efficiency: Modular scaffolding components minimized waste and maximized reuse.
Recycling Initiatives: Scaffolding components and consumables were recycled whenever possible.
Waste Management: Strict disposal protocols were followed for hazardous materials like asbestos.
Energy Efficiency: Energy-efficient tools and equipment were used to reduce carbon footprint.
