The connection between the roofing and any support structure is to be in accordance with the design produced by a scaffold engineer.

Step 1
Build a temporary scaffold tower at midspan of the roof as working area starting from one gable end to the other.

Step 2
Assemble the ridge beam(track included ) at exact height and connect to diamond beams(track included ) using the spigot with 6 safety pins to complete a first truss. Temporarily support the truss with short vertical tubes with right angle clamps.

Step3
Install the eave beam (track included ) at the ends of the roof truss.

Step 4
Secure the first truss to the existing perimeter scaffold support as per design produced by a scaffold engineer

Step 5
Repeat step 2,3 & 4 to assemble next truss on the next bay location.

Step 6
Attach the correct size of K-frame at the eaves and fix the next K-frame upslope to ridge beam at 2m interval.

Step 7
Install the horizontal braces in between of the K-frame at top chord to create a 1m lateral bracing for compression chord.

Step 8
Install the rollder braces located at the ridge beam and roof eaves inserted to the pocket provided.

Step 9
Install the diagonal braces at 1m interval in zigzag arrangement starting from ridge down to eaves.

Step 10
At this stage the first braced bay roof completed.

Step 11
Repeat steps 2,3 & 4 to assemble infill bay. Four (4) infill bays to install then repeat the braced bay installtion.

Step 12
Once the truss already assembled, install the correct size of horizontal braces at the eaves and fix the next horizontal brace upslope to ridge beam spaced at 1m interval for the top chord and 2m interval at bottom chord.

Step 13
Install the roller braces located at the ridge beam and roof eaves.

Step 14
Repeat steps 10,11 & 12 to complete the four (4) infill bays.

Step 15
Once the four (4) infill bays completed repeat the steps to install the braced bay.

Step 16
Continue to install infill bays and braced bays until the required length of roof completed.

Step 17
Once the roof structure completed . Pull the keder sheet over the track and secure to the scaffold. Refer to sheet installation . The sheet can be installed sequentially once at every bay.

Step 18
Once the roof completely covered, diamantle the temporary scaffold tower.

The connection between the Roofing and any support structure is to be in accordance with the design produced by a Scaffold Engineer.

Step 1
Ensure that the perimeter scaffold support is ready to support the crane-lifted roof in accordance with the design producedby a Scaffold Engineer

Step2
Establish a space where roof bays can be made on the ground. Once established, the space should be segregated to ensure the safety of the public.

Step 3
At ground level, create a temporary stepped working platform scaffold to be used in assembling craneable roof.

Step 4
Establish the correct height of the ridge beam. Connect two ridge beams(track included) with the desired length of brace frames supported by horizontal tube and fittings. Secure the roller brace into the pockets provided.

Step 5
Attached diamond beams to the ridge beams using steel spigot with 6-Ø12mm x70 locking pins.

Step 6
Connect the diamond beams for desired length and attached roof eave at both sides. All joint connections using steel spigot with 6-Ø12mm4 x 70 locking pins

Step 7
Continue to install K-frame starting from the ridge down to the eaves at 2m interval.

Step 8
Install the horizontal braces in between of the K-frames at top chord to create a 1m lateral bracing for compression chord.

Step 9
Install the roller braces located at roof eaves.

Step 10
Install the diagonal braces at 1m interval in zigzag arrangement starting from ridge down to eaves

Step 11
At this stage the first braced bay roof completed ready for craning.

Step 12
Attach the sling to its desired location as determined by the Scaffold Engineer. Four lifting points required with sling positioned to an angle not less than 70 degree from horizontal

Step 13
Lift the first fully braced bay into position and connect to the scaffold, ensuring the bay is correctly aligned. Secure the truss to the scaffold in accordance with the design produced by a qualified Scaffold Engineer.
Hand lines may be tied to the beams at the eaves, prior to lifting, to help guide the bay when lowering into position

Step 14
Create a second fully braced bay at ground level, by repeating steps 4 to 12.

Step 15
Lift the second fully braced bay into position. Horizontal Brace can be used at the eaves to establish the correct distance fromthe first bay. Secure the truss to the scaffold in accordance with the design produced by a qualified scaffold Engineer.

Step 16
The infill bay between the braced bays can now be completed Working progressively from the ridge down to eaves, install horizontal braces spaced at 1m interval for the top chord and 2m interval at bottom chord.

Step 17
Install the roller braces at the ridge beam and roof eaves inserted to the pocket provided.

Step 18
Continue the process until all bays are complete, and fixed to the supporting structure in accordance with the design producedby a qualified Scaffold Engineer.

Step 19
Pull the keder sheet over the track and secure to the scaffold. Refer to Sheet Installation. The sheet can be installed sequentially once at every bay.
