To achieve our ‘one team’ delivery we recognised the need to establish a joint working base. This was a key factor to the success of this project. We deliberately created an open plan office and by sharing our ‘one base’ with stakeholders and a greater skill base was able to be utilised in the most beneficial way for the project. Situations and issues were able to be managed in a proactive, rather than reactive manner.
During the blockade a further £3m of work was carried out on the Scarborough line to Seamer. Our ‘one base’ became a control centre for the whole project, thereby extending our collaborative approach beyond the bridge teams to include Network Rail’s maintainer, minor works, delivery team and their supply chain.
Working closely with Mabey Bridge, the fabricator, and Network Rail, the designer, we were able to adopt a swan neck design for the four new weathering steel beams, to allow the decks to sit on shallow 200m cill units which avoided breaking out existing masonry from the abutments and piers. The decks will demand no maintenance for 60 years. Using weathering steel also reduces the need for future maintenance.
The design allows full RU loading thereby increasing the capacity and reliability of this line. The pier and abutments were also strengthened and repaired. On the west side a cantilevered walkway was added delivering a safer working environment for track staff.
