3.3 Production and Erection
3.3.1 Panel production
• Refer to the pre-planning phase, to ensure a plan is developed for the appropriate location of the pour, given consideration for lifting sequence, crane access.
• Ensure the erection platform is capable of withstanding the downward forces of the proposed panels.
• All steel dockets to be kept as per document. • Formwork is prepared (Appendix E). • Project Manager to ask Electrician to locate panels with any conduits required prior.
When pouring is to be performed conduits can be placed. • The Box Numbers for each panel are to be recorded, as per the Building Casting Bed
Schedule (Appendix D). • Panels then released for pouring after the Site Manager signs off on the Panel
Fabrication Checklist (Appendix E). • Record the Date, Time and Ambient Temperature for each Concrete pour. • Sign off on the Panel Construction Master Checklist. • A Concrete Pour Record is then developed (Appendix F). • Testing/Sampling: The Site Manager needs to determine how the sampling regime is
to be managed. The Panel Fabrication Checklist (Appendix E) covers the fabrication of the panel. The concrete pour record (Appendix F) provides information on date, time and type of concrete that was included, weather conditions etc. The Site Manager is to discuss with the engineer to find a suitable sampling schedule. The Engineer determines the increase and the safety factor, so that the lifting can occur at a nominated period of days after the pouring. Cylinders from various panels are taken and then crush tested. It is important that during the curing of the sample it is left next to the panel to enable the same rate of curing. The progressive crush is to be verified by NATA laboratory, to achieve the required lift strength as specified by the temporary engineer.
3.3.2 Panel Lifting
• Ensure the site is briefed in the Site Toolbox meeting of the activity and location of the lifting of the panels. Site Communication is essential for ensuring the workers are kept informed of the lifting to occur. These are all to be documented, both site specific (everyone) and for rigging contractor performing the lifting. Everyone is to be signed on the toolbox meeting form.
• If practicable, exclude the non-essential trades from the site. • Rigging Contractor to discuss the Job Safety Analysis for the lift. • Rigging Contractor to check again the crane selected is suitable for the task, and the
boom is within radius.

• Rigging Contractor to refer to the Rigging Method Statement for Panel Installation (Appendix G).
• Ensure the copy of the Master file to be at the location for the rigging contractor is accurate.
• Cordon off the area to exclude all personnel not involved in the lift. If practicable, close entry to the gate and where practical the cordoned off area is to be three times the height of the panel.
• Use and compile the Panel Lifting Schedule (Appendix C).
Refer to and follow the Panel Construction Master Checklist (Appendix B)
• The panels are sequenced for the lift, as required by the engineer. It is the responsibility of the Site Manager to ensure each panel is lifted in the correct sequence.
• Rigging contractor to place temporary props. Stabilisation of both temporary and permanent structures is critical to the safe operation of the job.
• Rigger to torque each bolt and carryout checks as specified by the Bracing Engineer. • Panels inspected after erection and Brace Bolt Torque Checks & Panel Visual
Inspection Register completed (Appendix D). • Certifying Engineer to sign for the structure being in place. • Site Manager then signs off Panel Construction Master Checklist (Appendix B).

Appendix J – Tilt up & Precast Panel Awareness Training for Site Personnel
The contents of this information sheet must be communicated to all site personnel on EMCO Building projects where Tilt up & Precast Panels have been erected and braced prior to incorporation into the final structure.
1. Background
Tilt up & Precast Panels are a typical method of construction within the commercial building sector. Tilt up & Precast Panels may come in various sizes, shapes, thicknesses and finishes. While the use of Tilt up & Precast Panels is common, the hazards associated with their construction must never be
There have been and continue to be numerous cases of tilt panel collapse within the construction industry in Western Australia. In September of 2002 at a construction site in Myaree, a worker was killed as the result of a tilt panel collapse.
All site personnel are asked to take the utmost care when undertaking work on construction sites where Tilt up & Precast panels exist.
2. Training
It is a legislative requirement to have completed a Worksafe approved Carry Out Tilt Up Work Safely Course if your work involves the casting, transport, carnage, storage, erection, or stabilisation of tilt up or precast panels.
It is a legislative requirement to have completed a Worksafe approved Supervise Tilt Up Work Course if your work involves the supervision of any of the aforementioned activities.
It is a requirement of EMCO Building that persons involved in the drilling, coring, grouting, painting, cutting, patching of, or fixing to tilt panels while they are braced to have completed a Worksafe approved Carry out Tilt up Work Safely Course.
Site personnel must speak to their EMCO Site Manager of Supervisor if they are required to undertake work with Tilt up or Precast Panels and believe they do not have the necessary training.
3. Working Safely Around Tilt & Precast Panels
1. At no time are non essential site personnel permitted to enter the exclusion zone where tilt panels are being lifted or stabilised.
2. At no time are site personnel to touch, tamper with, or move props, braces or any other component which is used to lift, brace or support tilt panels.
3. At no time are site personnel permitted to climb on or over props or braces which are supporting tilt panels

4. Site personnel are asked to maintain a safe distance from propped or braced tilt panels at all times.
5. At no time are site personnel permitted to operate mobile plant (bobcats, EWPS, cranes, telehandlers) in the vicinity of propped or braced tilt panels. Where it is necessary to operate plant in close proximity to propped or braced panels, the EMCO Site Manager/ Supervisor must be informed so that adequate controls can be put in place to prevent panels collapsing.
