Built in 1933 and designed by engineer Alfred Dryland and Sir Herbert Baker, Chiswick Bridge uses reinforced concrete to span over 600 ft and is clad with over 3400 tonnes of Portland stone. The Bridge is an early example of this form of construction and together with the style employed and span, this gives the Bridge its Grade II status.
Our works included the investigation, recording, careful dismantle and re-instatement of the Portland stone balustrades to the entire bridge structure incorporating new impact resistant stainless steel re-enforcement; plus restoration of severely decayed bridge elements to original details.
The works involved:
- Laser survey of the bridge parapet to enable detailed drawings to be produced to enable the new stainless steel reinforcement
- Investigations and sample bay completion to prove design concept
- Removal of all parapet elements to enable steel frame to be incorporated
- All copings and plinth stones removed from site to be adapted to accommodate stainless steelwork
- 1000+core holes drilled into entire bridge to insert vertical steels
- 1000+ new stone balusters manufactured
- Stone parapets re-built with (invisible) steel inserted into the structure
