CHRISTCHURCH AIRPORT DATA CENTRE
McMillan Drilling successfully tendered and completed the construction of the abstraction and re-injection bores for the Data Centre air conditioning project. The works consisted of constructing a single 300NB abstraction bore to a depth of 35mbgl and a single 300NB re-injection bore to 15mbgl. Normal precautions such as installing pre-collars to contain re-injection pressures were deemed unnecessary given the shallow permeable nature of the local lithology. Cable Tool methods were adopted for this project due to limited site access.
