Project Overview
Legend Hire was engaged to design, supply, and install a temporary propping system to support the existing structure of a factory undergoing critical roof replacement works. The objective was to ensure the structural integrity of the building during the re-roofing process, enabling safe removal and replacement of roof components without compromising safety or stability.
Scope of Work
DESIGN
- Custom temporary propping layout developed by Legend Hire’s engineering team to suit the specific dimensions and loading requirements of the factory.
- Consideration of live loads, dead loads, and wind actions during the open-roof phase.
- Compliance with Australian Standards (AS 3610, AS 4100, AS/NZS 1170 series).
Supply
- High-capacity Legend Hire modular propping systems, including Legend50T props where required.
- Tilt prop racing system designed to provide lateral stability.
- All components tested and certified prior to deployment.
Installation
- Installation carried out by Legend Hire’s skilled Install team in accordance with Legend Hire engineered design.
- Use of Timber sleepers has spreader pads to distribute load and protect concrete floor.
- Bracing connections to ensure rigidity and prevent buckling or sway.
Inspection & Handover
- Final inspection and sign-off by Legend Hire site supervisor and structural engineer.
- Handover to client with all documentation, including installation certificate and compliance records.
Engineering Considerations
Load Calculations
- Assessment of roof truss and purlin loads during removal.
- Consideration of dynamic loads induced by wind uplift with sections of roof sheeting removed.
- Prop layout optimized to minimize interference with roofing contractor activities.
Safety Measures
- All props fitted with safety tags, load test certifications, and adjustment markings.
- Exclusion zones maintained during prop installation and dismantling.
- Works conducted under a Safe Work Method Statement (SWMS) specific to propping activities.
Outcome
The project was successfully completed with:
- Zero incidents or safety breaches.
- Structural stability maintained throughout the roof removal and replacement process.
- Timely completion in alignment with the roofing contractor’s program.
Legend Hire demonstrated its capability to deliver engineered propping solutions for complex industrial projects, ensuring safety, compliance, and efficiency.
