Queen Alexandra Bridge
Carrying the A1231, this four span structure is over 105 years old. Taziker was 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 Taziker 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 led to the development and implementation of many of our current procedures, which has been applauded by numerous auditors monitoring our management systems and all on-site audits assessing Health and Safety, Quality Control and the Environmental Protection systems deployed on the project.
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.
May 2005 - Sep 2007
The scope of the 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
