HOCHTIEF successfully replaced Chislehurst Road Bridge, a busy crossing used by through traffic and residents, which carries the A208 over a four-track railway in south east London. The new bridge maintains capacity and reinstates HGV access, easing congestion and creating better access for businesses in the area.
- Demolition of 33m single span, post-tensioned concrete beam bridge
- Construction of integral steel composite bridge
- Construction of heavy duty protection deck
- Carriageway and footway construction
- Utilities diversions using temporary services bridge
- Noise, dust, vibration monitoring
- Extensive stakeholder management
As the bridge is in a sensitive residential area, the client was concerned that the local community would respond badly to the works.
To counter this, we devised a methodology that removed the need for a hugely disruptive two-year road closure and months of night rail possessions. By installing a pre-fabricated, heavy duty protection deck under the existing bridge, we isolated the works from the railway, allowing us to demolish and rebuild the bridge during normal weekday hours. This minimised our reliance on night working, reduced the programme by nine months and saved £1.5m.
Although the scheme still involved a twelve-month road closure, our extensive community engagement meant stakeholders felt involved and became much more tolerant of the disruption. We won an “Outstanding Customer Satisfaction Award” at the Constructing Excellence in London & South East Awards 2013, and a Considerate Constructors Scheme “Performance Beyond Compliance”. We also won a SILVER Award from RoSPA for zero accidents.
