Coen Precast Site Visit
After the Site visit to Convenant College COEN pre-cast panels also invited me to come and
view their factory where they make the panels.
Coen Pre-cast panel site visit 29/05/08
An overall shot inside the factory. The panels are cast flat on large 'beds' that can be formed quickly inside the factory. Notice the Racked panels at the end of the factory, these are curing and once ready (usally 7days) are strong enough to handle the stresses of transportation.
In this shot a lifting pin and ferrul are visable. The reinforcement (not laid yet) provides strength to these external connections as they get tied to it. The position of the required components and even the size of the panel are read off shop drawings.

Convenant College Gym Site Visit
Convenant College site visit on the 28/05/05
Coen Pre-cast panels was erecting Panels for a gym at the school which they (CPP) let me watch and take photo's of.
The non structural Pre-Cast panels were cladding for the gym (portal frame), they were trucked in, hooked on using chains and a clutch type release and then craned into position. This type of crane was used(Franna 25T) becuase the panels did not require rotating or spinning to get them into position.
The crane then carried the panels to the desired position and lowered them onto positioning rods cast into the pad footings. The panel is bolted on using bolts which pass through cleats welded to the structural steel work.

Grout and small plastic packers are laid down underneath the panels to help get them level and to the right height.
Fine adjustment to the position of the Panel are made using a 'burke', which acts the same way as a large crow bar. Once the panel is correctly seated and level, its then bolted to the steel.
Atex Steel Site visit
Site Visit 22/05/08
We contacted Adam (manager) about a site visit to the ATEX steel shop where they fabricate steel beams and columns for tilt up panel buildings. The visit to the warehouse allowed us to gain an insite into the steel fabrication processes and provided usefull photo's and information for my major project.
Steel and plates and cleats ready for welding or casting into the panels. Adam informed us that they (ATEX steel) receive Engineer's details from the engineers that are then transferred (converted) into shop drawings, that can be used by the fabricators.
Welding and fabricating off-site allows for better quality product and less error. Productivity is also increased due to the warehouse providing shelter from the weather and a more comfortable and pleasant environment is created.

Tilt up and Pre Cast
I found a fantastic web site hosted by the Queensland Government regarding the Tilt up and Pre-cast concrete. (Codes of Practice) Great resource for imformation on the topic, so i thought it appropriate for my blog.
The site gives detailed explanations of all apsects regarding Tilt up and Pre-cast concrete and even contains detailed diagrams, such as the one shown below;
