MAINFREIGHT CHRISTCHURCH

In a joint venture with Leigh’s Construction, Dominion has completed this major staged project to provide Mainfreight with a greatly expanded capacity for their Christchurch operations.

9000m2 NEW Food Warehouse:

Large steel portal frame structure (ridge height –15m); Precast Concrete walls (130+ panels); specialist low tolerance post-tensioned slab. The construction sequence required temporary design for propping large 15m high precast panels and involved a complex floor construction requiring pre-loading of the sub-base, followed by gas collection pipework and membranes as the site was formally a land fill. Other aspects of the project scope include a 2 storey office & amenity fit-out.

12,000m2 NEW Freight Terminal and Offices:

Large steel frame structure – 85m wide building by 150m long structure (ridge height –11m); Precast Concrete walls (100+ panels); specialist Denka CSA slab. The large structure included specialist Steltec structural steel members; rail sidings construction and a raised dock slab constructed using Denka CSA concrete additive for joint free construction to suit the forklift loadings of the terminal operation.

10,500m2 Existing warehouse building:

Extension and strengthening/retro fit of existing structure – Large steel portal frame structure (ridge height –15m); Precast Concrete walls (110+panels); specialist low tolerance post-tensioned slab. The construction sequence required temporary design for propping large 15m high precast panels and involved a complex floor construction requiring pre-loading of the sub-base, followed by gas collection pipework and membranes as the site was formally a land fill. The existing structure is being strengthened to bring it up to new building code requiring extensive new steel bracing and foundation works.
