Deck Half Joints
Last updated on 3 Oct 2012
A tender for the sum of £323,836 was awarded to Raynesway Construction in February 2012 to carry out a trial replacement of a limited number of the deck joints on the main and side spans.
The trial will determine whether or not an alternative half joint detail can help to minimise the issues that are caused by the original detail. These include a large amount of maintenance time spent repairing the existing joints using overnight carriageway closures and occasional emergency daytime temporary closures; the secondary effects of the dynamic loading on some truss members and surfacing, and the ride quality experienced by users.
Work commenced on site in August 2012 and following extensive engineering design work by Fairhurst, the Engineers for the project, a further revision to the detail and method of installation has allowed the trial to go ahead without requiring daytime weekend closures. All the required carriageway closures will be now be carried out overnight which will minimise disruption to users.
As in all cases involving working overnight on the bridge, noise and other environmental issues will follow guidance set by both Fife and the City of Edinburgh Council. However, there is the potential that works overnight involving steelwork modifications, whilst within acceptable noise levels, can still cause disturbance to some local residents especially on calm evenings.
