Forming the soffit with a specialised solution

Forming the soffit with a specialised solution

Waterway Constructions faced a major formwork challenge on the Bridge over Hawkesbury project, located on the Hawkesbury River, NSW. This challenge involved forming the soffit, within the confines of the coffer dam which was also compounded by severe time constraints, significant concrete loads and a lack of available support points.

In true market leader form, Uni-span designed and produced universal beam fabrication drawings which incorporated our unique formwork solution.

By making use of the significant capacity of the MK-120 Waler and the versatile MK Structure system, we were able to keep the amount of required fabrication to a minimum and provide a predominately standard solution to a very bespoke situation.

All structural steel support structures were designed to AS4100 and detailed according to the Australian Steel Detailers’ Handbook.

Uni-span created the soffit, shutters and access platforms out of our Enkoform product, with the soffit support structure made up of a combination of fabricated structural steel and MK elements.

100 sqm of formwork product per pier was supplied to this 8 week contract.
