Nazeing Phase 5 Works Complete
Congratulations to Billy Knight-Wood and our team at Nazeing New Road Bridge for hitting another major milestone in the comprehensive refurbishment of this structure. The Phase 5 works included preparations for the jacking of the bridge to allow replacement of the bearings.
A Portadam was installed to reduce the pressure on the river wall and allow excavation for construction of the pad foundations for the jacks. The complex operation presented many challenges for the team to overcome such as excessive ground water ingress and space constraints.
Approximately 120 tonnes of spoil was removed using barges. Due to the presence of water, to pour the foundations, part of the concrete had to be tremie pumped. This method of placing concrete avoids the washout of cement from the mix when the pour is under water to ensure a reliable strength of product.
The team are now setting up for Phase 6 Bearing Replacement Works.
Well done to the whole team for your continued focus and meticulous planning on this technically challenging scheme.
