Safety Socket

The Challenge:
The Façade design at roof level is extremely challenging and requires a complex network of secondary steelwork to be installed at the building’s edge on both Level 52 and Level 53 which is one of the most high-risk elements of the project. This is mainly due to each Steel post requiring four loose nuts to secure it in place, therefore installing 500kg steel sections at 180m from the ground requires some innovative safety measures.

The Measures:
Balfour Beatty worked with Yuanda Europe (Façade Contractor) to see what method could be implemented to tether each of the nuts required to fix the large Steel sections on Level 52-53. Each Steel section requires 4 individual nuts to secure the section to the bracket, and due to the nut needing to be twisted onto a threaded bar, no tether could be installed.

The solution was to fabricate a ‘Safety Socket’ which each nut could be placed into and held in place with a grub screw. This solution meant that each nut could be secured and safely installed without the risk of falling from the tower. This unique solution was detailed and provided by the Yuanda site team as no other solution’s were available on the current market.

The Results:

• Each individual nut tethered.
• All Secondary Steelwork brackets installed at Level 52 and 53 without incident.
