SA242 Penallta Road Bridge Strengthening
Caerphilly County Borough Council, through its Engineering Projects Group, is procuring works to strengthen Penallta Road Bridge on Penallta Road, Ystrad Mynach, Hengoed, in Caerphilly County Borough, Wales. The appointed Principal Contractor will construct a reinforced concrete box structure beneath or around the existing bridge to provide long-term support, infill voids with foam concrete to achieve full load transfer and structural continuity, and install permanent blockwork formwork with blue pennant stone cladding to all exposed faces, mechanically tied at both end elevations. The existing superstructure will remain in place, but the works will materially change the bridge’s structural arrangement and load-bearing behaviour. The estimated contract value is £600,000, with the delivery timeframe not stated in the available information, and the work will be carried out at the Penallta Road Bridge site in the UKL16 region. The critical qualification requirement is appointment as a suitably qualified and experienced Principal Contractor.

From the official notice
Caerphilly County Borough Council (CCBC) is seeking to appoint an external suitably qualified and experienced Principal Contractor to undertake works to Penallta Road Bridge, Penallta Road, Ystrad Mynach, Hengoed, Caerphilly County Borough, Wales, CF82 7GN. CCBC’s Engineering Projects Group (EPG) is the client for this project and will oversee the works. The proposed strengthening solution comprises the construction of a reinforced concrete box structure designed to provide long-term support to the existing asset. Any voids between the existing structure and the new reinforced concrete box will be infilled with foam concrete to ensure full load transfer and structural continuity. Permanent formwork will be utilised, consisting of blockwork construction with blue pennant stone cladding to all exposed faces, mechanically tied at both end elevations to provide a durable and aesthetically sympathetic finish. It should be noted that the existing superstructure will remain in situ. However, the introduction of the reinforced concrete box and associated infill will fundamentally alter the structural arrangement and load-bearing behaviour of the asset when compared with its current configuration.
