PART 2 Building product manufacture
Reinforced concrete prefabricated wall panels

Product and Purpose
reinforced concrete prefabricated wall panels used in wall construction for Commercial or residential projects

Cast Off-Site Concrete Panel Walling
In this method, the solid concrete panels are cast in moulds on a level surface (usually a smooth steel base) in quality-controlled factories away from the building site. The panels are then left to cure to the appropriate level of strength. Once cured, they are stripped from the moulds, lifted into storage areas, and

transported to the site only when they’re needed.
The concrete panels are installed with a mobile crane, which lifts the panels from the transport trailers directly into their final positions. The panels can be temporarily braced until a sufficient number are installed to form a self-supporting braced structure. Panel thicknesses usually range from 150 mm to 250 mm.

Plotting the wall element
The designers / Draftsperson draw all precast elements from the manufacture using the state of the art facility which is similar to AutoCAD. the engineers are then to check all the drawings and design calculations once that has been done the work is marked approved and sent to the host computer of the factory. The electronic information describing the 3d model received by the factory and sent electronically to the plotting station each concrete element is marketed out on the steel palette. This stage includes as well includes the panel shape, any cut outs and any cast in items such as of the electrical boxes and conduits. Magnetic shelters are then sent to a clean machine to ensure of a high quality tolerances on edge of the panels.

Moulding & Placing electric/water installation

The shelters are then places along the plotted lines and the electrical boxes or any of the cast in items are glued onto the steel palette. The shelters and boxes are then coated the a realise oil and any small joints are sealed.

Inserting reinforcing

The reinforcement cover spaces are placed . the palette is then moved along to where the reinforcing is cut bent and placed accurately on the cover spaces , any additional steel reinforcing is added then the lattes girders are placed as well once all is complete the steel is tied and the listings hooks are fitted. Any conduits or cast in items are also placed at this stage. Plastic coated steel rockets are placed to specified centre integrals to ensure the two concrete skin walls are kept evenly apart to the required thickness.

Concrete filling
The concrete is then ordered by the operator from the fully operated batching plant. (The concrete is made to the specific requirements by the Australian standards).

Vibration and Rotation

Storing the walls

PART 3 Buildings Defects


A defect in an older building may also be caused by lack of adequate maintenance. General maintenance items, such as re- bedding and re-pointing of roof hip and ridge tiles, repainting, normal wear and tear as well as ageing are not a defect. Typical cracks to brickwork and contours of timber floors affected by clay soil movement is not structural and...
