Shaldon Bridge Strengthening
Shaldon Bridge is a Grade II listed bridge, spanning the River Teign. SWH Civils was appointed by Devon County Council to undertake essential refurbishment works on the bridge as the existing structural tie bars and paint system had perished over time.
Key elements of the scheme included:
- Replacement of 92 stainless steel tie bars
- The grit blasting of steel elements to prepare for re-painting
- Application of a new three-coat paint system
- Safe methods of working over tidal estuary
- The erection of underslung scaffolding and encapsulation to prevent contamination of the estuary
- Traffic and pedestrian management
SWH Civils worked in compliance with the Environmental Agency and Marine Management Organisation to ensure that our works were completed with minimal impact on the environment. This included ensuring that scaffolding was only attached to six spans at a time, so that the water flow of the river would not be significantly affected if there was a period of high rainfall.
Working within an intertidal area, the phasing of the works, especially to the piers was critical. To maximise productivity, our works were planned not only accordance with tide times but also taking account of neap and spring tides during daylight hours.
The tie-bar works were successfully completed within three weeks and the painting works within 20 weeks.
