Time-lapse photos show progress on Christchurch's Town Hall
Two time-lapse cameras are recording daily progress on the $127.5 million restoration of Christchurch's Town Hall.
The cameras are capturing changes to the Warren & Mahoney-designed building as contractors work to strengthen its foundations and repair the damage wrought by the Canterbury earthquakes.
The project is one of the biggest conservation projects being undertaken Christchurch.
Seven months into the project and the extensive nature of the conservation work being done is clear to see.

Demolition of the old Boaters restaurant is complete and contractors Hawkins are making steady progress with the foundation work.
Contractors have been injecting large concrete piles eight metres into the ground using three grout machines imported from Germany specifically for the task.
The 1000 columns will overlap and interlock to create an earthquake-resistant underground wall that will protect the building from any soil movement.
The work will need a total of 27,000 cubic metres of jet grout concrete – enough to fill 270 average family swimming pools, 37,500 bath tubs or 200 buses.
Town Hall project manager Patrick Cantillon said the project was progressing as planned and no unexpected problems had arisen so far.
"We are tracking along quite nicely with the jet grout columns – we've done the back of the house and the auditorium areas . . . and are working west towards east across the site. We haven't found anything we didn't expect to find and it is all going to plan," Cantillon said.
Hawkins aimed to have the jet grouting completed by June. Once that stage of the project was completed, the existing concrete slab would be removed and a new one laid.
"Following that we'll start putting back in the fabric we took out," Cantillon said.
The goal was to have the foyer and main auditorium of the Town Hall ready for opening in early 2018.
The rest of the building was expected to open later that year.
