Administrators and developers spent the weekend racing to uncover the status of eight projects left stranded by Roberts Co when the Sydney-based contractor put its Victorian arm into administration to staunch mounting losses already topping $60 million.

Roberts Co VIC’s collapse on Friday shut down work on Amazon’s biggest-in-Australia automated warehouse project in Craigieburn on the Hume Highway, Investa and Oxford Properties’ 702-unit build-to-rent project in Footscray, and Golden Age’s 28-level strata office on Little Collins Street in the Melbourne CBD.
