The Queen Alexandra Bridge in Sunderland is a Grade II listed structure spanning the River Wear in Sunderland.
The scope of works included:
- Over 52,000m² of steelwork was grit blasted and three coats of paint were required to ensure the structure could withstand the surrounding marine elements for another 25 years
- Over 60,000 litres of paint and 2,700 tons of expendable abrasive were used to achieve the level of protection necessary
- 33,000m² of Envirowrap heat shrunk sheeting installed around the scaffold to protect the river below, that’s more than 4 Wembley Stadium pitches!
Carrying the A1231, this four span structure is over 105 years old. Taziker Industrial (TI) were tasked with ensuring that the structure remains fit-for-purpose in the coming years.
Learning and Innovation
The entire project was a valuable learning experience for TI and many lessons were learnt as part of this project that we have gone on to apply to projects we have completed more recently; such as the Royal Albert Bridge and Tay Rail Bridge. It directly influenced some of the procedures we still have in place now and
For example, we utilised the Envirowrap system to protect the surrounding environment and the river below from dust and debris caused by the works we were carrying out. All debris created as part of the grit blasting process is contained within the encapsulated scaffolding and is extracted once work is complete to minimise the effect on the environment.
