O maior projeto de Engenharia Civil da Europa está acontecendo em Londres, capital da Inglaterra. Em construção desde 2009, com conclusão prevista para 2018, os novos 50 quilômetros de túneis (que estão sendo escavados a 40 metros de profundidade) do metrô de Londres vão custar 18 bilhões de euros!
Esta ampliação do metrô ligará a capital inglesa ao aeroporto de Heathrow, e às cidades de Reading e a Essex.
Oito máquinas de escavação, conhecidas aqui no Brasil como “tatuzão” estão sendo utilizadas para escavar estes túneis. Com 6 metros de diâmetro, elas funcionam 24 horas por dia, coordenadas por grupos de trabalho que se revezam nos três turnos da obra. Mais de 3,4 milhões de toneladas de terra já foram removidos, valor que será duplicado até o fim da obra. Toda esta terra será depositada em um bota-fora com 6,07 km2.
Segundo a CNN, esta expansão corresponde a 10% das linhas que já existem, o que melhorará a mobilidade de 1,5 milhões de pessoas. Espera-se, contabilizando o fluxo turístico da cidade, que este novo o sistema seja utilizado por 200 milhões de pessoas por ano.
Dez novas estações de metrô serão criadas, e serão capazes de receber composições de 200 metros de comprimento.

The station has been created by constructing a concrete box in the North Dock 250 metres long and 30 metres wide; approximately the same size as One Canada Square lying on its side.
