CCL GB – landmark in London

The CCL GB team attended the topping out ceremony for Strata SE1, which is 147 metres in height and is the highest tower in South East London. Completion of the project was ahead of schedule and was the first project to utilise the ETAG approved X range of anchors.

The design objective for the tower was to achieve a flat soffit within the tight floor-to-floor heights while maintaining a minimal floor thickness. The use of post-tensioned slabs allowed a minimal slab thickness of 200mm throughout. This would be impossible using traditional RC construction. The use of CCL post-tensioning dramatically reduced the cost of the formwork and increased speed of construction of the tower, which was built at a rate of one floor per week.
