This is an ingenious and practical solution to the challenge of building over a busy railway station with minimum disruption to railway traffic. The new station building was entirely assembled in the adjacent car park in two large parts which were then lifted into place. Each lift weighed approximately 120 tonnes and required a large crane to be shoe-horned into the restricted site. The process achieved significant safety advantages and reduced the overall cost and programme of the works.
This is an excellent example of the structural engineer's ingenuity leading to a safe and economic solution in difficult circumstances. Working with the original designers, the contractors came up with a time saving erection method – improving safety conditions.
