KARARA IRON ORE PROJECT - EARTHWORKS AND CONCRETE
Karara Mining Limited
Karara Iron Ore Project – Earthworks and Concrete
500 kilometres north east of Perth and
225 kilometres east of Geraldton, Western Australia
Representing the largest major concrete works package NRW has undertaken to date, the project encompassed most of the preliminary construction work for the iron ore crushing and processing facility.
Works included the construction of major concrete foundations and structures for the plant and associated infrastructure, including ball mills, primary and secondary crushers, load out vault, and conveyor trestle foundations.
The pouring of more than 50,000 cubic metres of concrete was a major component of the project. As well as site earthworks and concrete foundations, the contract included construction of site drains, and 18 kilometres of access roads, a retention pond and the all-weather aerodrome.
The earthworks and roadworks for the plant site and associated infrastructure had an approximate total volume of bulk earthworks of 500,000 cubic metres of cut to fill and borrow to fill. NRW’s internal division, Action Drill and Blast carried out approximately 50,000 cubic metres of drill and blasting.
This project was significant not only because it was the first major concrete package undertaken by NRW but it also showcased NRW’s ability to deliver a major project combining the two key civil elements of bulk earthworks and concrete structures. This allowed NRW to remove all interface issues that commonly occur between these disciplines, saving significant to construction time for our clients.
