A major Australian company operating a steel manufacturing plant required
maintenance on its plant. The company called for tenders to replace roofing
covering the hot (1250c) rolled steel mill and pickle line (a hydrochloric
acid process). The heat from the hot rolling and vapours from the pickling
processes had caused significant damage to roofing structures (purlins and
cladding).
The RAWP solution uses a suspended frame with underneath access for workers
to safely access roof surface and structures.
The frame has a capacity to lift 140 square metres of either new or existing
roof in a single lift. The frame¹s lifting and access capabilities enable a
modular roof replacement process.
The modular roof replacement process for large scale industrial roofing;
maximizing worker safety whilst minimizing plant interruption; are the
significant improvements as a result of the RAWP innovation.
The new roofing structure is assembled at ground level on a jig, the frame
lifts the existing structure off the building, and then the new roofing
structure is attached to the frame and lifted to be secured to the building.
The building is left open for approximately 20 minutes. With this process
workers are secured within the frame for any work off ground level.
Without the use of the suspended RAWP compliance with OH&S requirements
would have necessitated significant scaffold structures and drop nets, and a
plant shut down for the duration of the project to maximize worker safety.
Case Study 2
Client:
Port Of Melbourne Authority
Location:
Melbourne Docklands
Roof works are dangerous - "no matter how simple the job may be".
Through age and severe weather, the buildings on Melbourne docklands sites are subject to relentless weather conditions, far more than virtually any building or structure in Melbourne. Compromised by high winds and storms, salt and sea spray, and other associated industrial pollutants, along with the surprisingly high degenerative effects of seagulls and other local bird life, these sites may look safe - BUT THEY ARE NOT!
The combined net effect of these conditions results in many buildings being difficult or impossible to get trades safely onto their roofs in order to undertake restorative works, fix leaks and skylights, or replace individual or multiple roofing damaged or dangerous roofing sheets.
The age of the roof sheet (some of which are Asbestos), and the absence of Safety Mesh (in many cases), combine to create hazards for any roof works no matter how simple the job may seem. The SRAWP frame has solved many of the above problems, by providing flexible access to the wide variety of roof structures here in the docklands.
The SRAWP allowed for extensive works to be completed with relative ease, efficiency, and flexibility and above all SAFELY. It is also worth noting
the SRAWP method proved to be 40% cheaper than than the alternative
(scaffold).
