Quattro Ports’ Berth 103, is a joint venture between Qube Holdings, Noble Group, Cargill Australia and Emerald Grain. Located at Inner Harbour, Port Kembla the open-access terminal introduces significant export opportunities for the Australian agribusiness sector. The massive terminal provides the capacity to handle 1.3M tonnes of export grain annually, with an innovative design, which allows it to multi-purpose for import and export of a range of agribusiness product.

Grain Silo Export Facility

Initial Scope:

Kerman Contracting was awarded the $67M contract to design and construct a new Grain Export Facility.  Kotzur, a family-owned grain handling and storage specialist, located in Albury, NSW, was contracted to develop the grain handling facility, the biggest by volume and contract value project that Kotzur had undertaken in its history. Kotzur subsequently engaged SOTO Consulting Engineers to conduct the assessment of several critical structures associated with the grain handling facility.



SOTO employed their significant expertise in wharf design, conveyor design, bulk materials handling, civil and structural engineering to provide a full service structural and design engineering solution in support of the grain handling & storage contractor Kotzur. The Grain Storage Area, which comprised eight flat-bottom and nine smaller conical-bottom silos; a road receival hopper; bucket elevators and conveyors for materials handling was principally designed and supplied by Kotzur. Kotzur and SOTO collaborated on the structural elements of the work to ensure the schedule would be met in time for manufacture & construction milestones for the project.


The latest simulation methods and computer-aided engineering (CAE) processes were utilised to ensure all tower and gantry structures were designed in the most accurate and cost efficient manner. The SOTO team were also quick to identify, analyse and account for the changing structural details during the manufacture and construction to minimise any delays to the project.


All structures for the Quattro grain handling terminal were completed to meet and exceed the requirements of the current Australian standards, with SOTO quickly responding to project challenges and scope changes to achieve the best outcome for the client. SOTO’s innovative designs met the client’s brief for the facility to be truly multi-functional, with the ability to provide export and import capacity, as well as handle a broad range of agri-product.


What made this such a successful project was the collaboration between the suppliers and contractors engaged to execute the work. At an initial kick-off meeting between the directors of Kerman, Kotzur, Mainteck and SOTO, it was agreed in principal to deliver a world class facility that would benefit the Illawarra region for decades to come. The experienced gained by the SOTO team in this agribusiness project will increase its reputation as a leading supplier of engineering services to the grain and seed industries throughout Australia.


Opened in January 2016, the facility soon neared its capacity of 150 000 tonnes per month, regularly doing 100 000+ tonnes months by early 2017.
