At the start of 2014 Banagher Precast Concrete tendered HOCHTIEF (UK) Construction Ltd.for the Dauntsey and Notton railway overbridges for Network Rail on the Great Western Electrification Project Phase 9. Three weeks later we secured the order and started the design phase.
We worked closely with Hochtief and Hyder to get the design and production drawings prepared as the programme was very tight. Notton was staright forward in that it was a staright Portal Frame overbridge however Dauntsey was a skewed unit which took more detailed analysis and a more time consuming mould. Notton Overbridge had 3nr portal roofs, 2nr parapet panels and 2nr cill beams. Dauntsey Overbridge had 4nr portal roofs. 2nr parapet panels and 2nr cill beams. The portals had a deck stitch so a trial fit was erected in our factory to demonstrate that the units fitted accurately and that there was no clash with projecting rebar. This meant that when the units went to site Hochtief were on the front foot straight away in terms of confidence of fit and the installation went in well ahead of time.Google+
