Heavy Duty Capping - Case Study 01

Heavy Duty Capping of CAZ48 Box AZ18 infill pile wall. BAE Systems, Clyde River, Glasgow, Scotland, 2006

Dawson’s Heavy duty capping system was used by “Farrans Construction Ltd.”, to create a 1.5M high cope along a CAZ48 Box - AZ18 infill pile wall. The reusable system replaced the need for complex and expensive on site welded fabrications which have to be cut off and made good when the job is finished.

The weight of concrete supported per 3m panel was 6 tonnes well
within the 30 tonnes max load. Ø85mm holes were burnt through appropriate piles at a predetermined height. The brackets were lowered into position using a sling, cam inserted through hole and engaged. All
brackets were then adjusted for height and level. The soffit panels were then positioned and secured to them. The pile contour was filled in by pushing the panel soffit bars forward. This created a secure platform for the workers to build the cope steelwork and side shuttering on.
After the cope wall had set, approximately 24 hours, the side shuttering was removed. The panels were unbolted and the brackets lowered creating a gap between the soffit bars and the underside of the cope. The panels were then removed, cleaned and reused.
