Temporary Works

We also undertake the design of custom-built falsework and other forms of temporary works and support systems.

St. John’s River Bridge, Jacksonville, Florida
Contractor: Recchi
Large temporary props to provide stability and resist out-of-balance moments during construction of one of the longest balanced cantilever spans in North America. Also, falsework for the cast-in-place construction of the side spans: after pouring the first span, the entire falsework was skidded across and re-used for the second span.

Boyne River Bridge, Drogheda, Northern Ireland
Contractor: Cleveland Bridge
A development of the same system in which the falsework was designed to be removed after the lower half of the sloping legs of the pylons had been poured and was then re-assembled for construction of the upper part of the pylons.
