UNDER WAY: The concrete pour for the temporary police station started today.
Work on Christchurch's temporary central police station has ramped up, with the first stage of the building's foundations now in place.
About 1100 cubic metres of concrete was poured at the St Asaph St site today, beginning the foundations for the single-storey building.
Police decided in December to move out of their 40-year-old Hereford St building because of concerns another major earthquake would cut essential services.
The general building design for the temporary site is finished and the $20 million project is on track for completion in November.
Canterbury district commander Superintendent Gary Knowles said police staff were excited about the project.
''This is an important project for the city and for the people of Christchurch, and signals our ongoing commitment to a central-city presence,'' he said.
''It's great to see construction work on the site now well and truly under way.''
Staff were coping well with ''makeshift conditions'' on the lower floors of the Hereford St building and at other stations, he said.
Police formally took over their new site on June 1 after demolition work and site clearing was completed in late May.
Excavation of the site was finished early this month, with 3150 tonnes of soil - about 128 truck and trailer loads - taken away.
Initial building consents for the structural and internal elements of the building have been lodged.
The second stage of the concrete foundations will be poured next week
