Key Project Facts


The Christchurch Bus Interchange was the first Anchor Project to be delivered in the central city. Southbase was engaged as the Main Contractor for the design and build stages of this high profile development.

The large-scale construction project demanded considerable collaboration between the Design Team and Southbase in order to develop solutions to achieve cost efficiencies whilst still future-proofing the project and ensuring on-time completion.

Challenges and Solutions

At the time of tender, Southbase provided a fixed-price lump sum to complete the design and construction of the building, including all regulatory consents. This was achieved as a result of Southbase’s ability to add value at the design stage and to leverage strong sub-contractor relationships.

The Southbase team undertook a full re-engineering of the foundations to produce significant cost and construction time-savings. Modulating and re-drafting the structural steel design in BIM also allowed for an accelerated erection time and more efficient co-ordination with other trades.

The Project Team also collaborated to ensure forward planning for future development of the building. Southbase were actively involved in these discussions that resulted in the slab being designed to withstand the possible construction of a three storey structure on top.

Value was added by Southbase at other stages of the programme, including recommendations for viable alternatives to speciality exterior cladding and internal feature soffits in order to provide significant cost savings to the Client.

Delivered in two separable portions in just ten months, Stage 1 (SP1) was operational after just eight months of operation, whilst Stage 2 (SP2) continued construction right next door.
