The project is now 60% complete on an earned value basis with major vendor procurement packages over 90% committed with fixed costs.
At the process plant, site concrete foundations poured by Flanco are more than 80% complete, installation of structural steel supplied by Metro Steel has commenced and first carbon steel tanks have been installed by Proweld.
All permanent buildings are now on-site and installed, including the permanent village, construction village, warehouse, workshop, administration, reagents, laboratory, ablutions, crib rooms and 4G communications.
“On-site activity accelerates”
Long lead time items are arriving and being assembled at the site including the Veolia crystallisers with associated components and tanks, and transformers from Wilson.
SO4 chief executive officer Tony Swiericzuk said: “On-site activity will be accelerating over the coming weeks as we move into the peak construction phase of the process plant and non-process infrastructure.
“The SO4 owners’ team and GRES continue to do an outstanding job driving all workstreams on-schedule with first SOP production due in quarter one 21.”
Vendor packages in transit to the site include lump breaker, attritioners, wet screens and centrifuges and are anticipated to be installed in quarter four of 2020.
