Caldecott Excavation (II)

Deep excavation works continues at the Thomson Cripple Siding. Installation of struts have almost reached across the entire length of the Caldecott station box.

Rock has been interfaced at this stage of the excavation, and expertise have been called in with the use of special detonators to mitigate the vibration and minimize ground disturbance to the neighbouring skyscrapers, and most importantly the adjacent operational Circle Line.
