MINING towers plus construction of a new 66 / 11kV substation , relocation of a 66kV Ausgrid transmission line and various overhead and underground HV works including all 11kV site wide reticulation .
To complete the project as efficiently as possible , Downer / QCC entered into an alliance contract partnership with Xstrata Coal , now incorporated into Glencore .
“ We set up an alliance partnership between Downer / QCC and Xstrata Coal to form a good working relationship that could effectively deliver all the key aspects of the project in a timely manner ,” says Swanson .
“ Our teams were onsite for two and a half years delivering two million site hours with over 650 people onsite at the peak of construction . Importantly no lost time injuries were incurred and the project achieved a total recordable injury frequency rate ( TRIFR ) of 5.7 .”
QCC had been working with Glencore in alliance projects since 2005 , including CHPP work at Mt Owen , Liddell and Mangoola , and started work on Ravensworth North back in 2009 when QCC began assisting in the project for Xstrata Coal .
“ We started off in 2009 doing a concept study for Xstrata , that progressed into a pre-feasibility study , followed by feasibility study and then set the design and scope for the Ravensworth North project ,” says Swanson .
One of the biggest challenges in delivering the Ravensworth project was that it had to be constructed within an existing operational facility and was therefore governed by a wide range of constraints , incorporated within a large geographical area .
The project provided a 3000 t / h raw coal delivery system , two new 900 t / h processing modules , rejects handling and product stockpiling / reclaiming facilities . According to Swanson , an interesting fact is that the project required 14 new conveyors to be designed and constructed .
“ The total length of the new conveyor network was over 9 kilometers . In addition , upgrades were required for existing conveyors which covered just under 5 kilometers , bringing the total length
