The Bolton Interchange project provided the centre of the town of Bolton with a major infrastructure improvement of a brand new bus and rail interchange – making travel easier for inhabitants and visitors.

PCE Ltd were approached by Kier Construction to provide an offsite build solution for the original insitu concrete designed podium deck that supports the bus station passenger concourse and bus roadway.

The location of the site in the centre of the town required concise logistic planning for all deliveries. Due to the proximity of two live railway lines adjacent to site boundaries, night time possession work was required to be undertaken. It was thus critical that the delivered precast units would be accurately designed and manufactured to fit first time to ensure there was no overrun of the possession periods.

Working with Kier, Transport for Greater Manchester and their design consultants, PCE developed a fully computer modelled Hybrid structural solution that would require the offsite production and delivery of over 850 components and the placing of over 1,500m³ of insitu reinforced concrete over the precast deck units.



Offsite manufacture ensured the fit of components into the structure on a first time basis direct from delivery vehicle.


Highly detailed construction sequence planning of night and day deliveries to ensure minimal disruption in busy town centre location.


Night time construction carried out adjacent to two railway lines in tightly controlled track possession periods.
