Arena drilling underway
by Mike Isle
Drilling at the Canterbury Arena site will fast-track the project as geotechnical investigations have begun to determine the condition of the land as part of the Investment Case being prepared for the arena.
In total, 81 separate tests will be undertaken to give detailed information across the entire site, which will allow the Investment Case to consider the most favourable areas for construction, assess options for the arena layout, develop conceptual designs for the form of the arena and its foundations, and evaluate any uncertainties related to the ground conditions.
“Early work will ensure we have the best information right from the start to feed-in to the design process. We know that similar ground conditions exist across the city, from other work already underway,” says Greater Christchurch Regeneration minister, Megan Woods.
Christchurch mayor, Lianne Dalziel, says the opportunities that this project will enable upon completion will make an enormous difference to the city and the region.
“We will see more enabling work carried out over coming months as the Investment Case progresses so that the project can get underway as soon as possible and not suffer delays due to ground preparations not being completed.”
Drilling rigs are taking ground samples during two weeks, and this will provide information from nine deep boreholes at a depth of up to 30 metres, 11 shallow boreholes drilled to five metres, 46 Cone Penetration Tests of up to 30 metres, and 15 excavator trenches (pending consent) dug to depths of four metres.
