Project involved delivery of site-wide infrastructure for the creation of a major new processing plant manufacturing and supplying TAN (Technical Ammonium Nitrate) to the Australian mining industry. The facility spans 35 hectares and is located in the Pilbara.
With a peak workforce of over 400 working across the 35-hectare site, WBHO delivered a full suite of civil infrastructure services, incorporating high-volume bulk earthworks, site-wide drainage, services, hardstands, a substantial road network, and temporary facilities including offices and warehouses.
The project was notable for its challenging ground conditions and environmental considerations. Ground conditions encountered during the bulk excavation works were significantly different to those detailed within the reference geotechnical report, with substantially lower volumes of materials suitable for fill. WBHO worked with the client at site level to resolve the issue, and collaboratively revised the construction strategy so that schedule and budget could be maintained.
The site adjoins the proposed 5,000 ha Burrup Peninsula Conservation Reserve, and is close to popular recreation areas, such as Hearson Cove. Dust emissions were a key concern, particularly during trenching and filling. WBHO put in place industry best practice suppression measures to minimise environmental impact.
WBHO’s collaborative approach was also evidenced in working with the client to optimise value for money outcomes for Tecnicas Reunidas through various design refinements, such as alterations to the road pavement design while maintaining required functionality and Whole of Life.
