Images and video | Laing O’Rourke installs Everton stadium roof truss

Each truss, which initially rest on temporary support trestles built into the stand, consists of three sections. They are assembled at ground level and lifted into placed individually. Each of these 15 steelwork sections weighs approximately 100 tonnes.

The completed roof trusses will have clear spans of between 150 and 175 metres. The depth of the trusses varies between 4 metres deep at the supports, to around 11.5 metres at mid-span.

Last month, Everton FC released a video showing Laing O'Rourke’s progress on other aspects of the £500m stadium.

It has built a new structure to connect the rear of north stand to the roof trusses. Elsewhere, Laing O’Rourke has taken delivery of the concrete raker beams for the construction of the east stand. And it has poured concrete on the third level at the west stand.

The 52,000-capacity Bramley-Moore Dock is scheduled to open in mid-2024.
