Contractors have today started digging up the site of the Canterbury Television building which collapsed in the February 2011 earthquake as part of the ongoing police probe to see if anyone is criminally liable for the disaster.
The soil, South wall foundation and parts of the North wall foundation on the site where the six-storey Christchurch office block once stood are the latest focus for the complex technical criminal investigation which is yet to establish whether anyone will be charged with the building's pancake collapse, which claimed 115 lives.
Contractors using small diggers and concrete cutters this morning started work to dig eight test pits or trenches to allow soil specialists and engineers to examine the soil and foundations.
"This site work is expected to be completed within the week and the site will then be reinstated to its former condition," Detective Superintendent Peter Read said on Friday.
