b'Remediation, rehabilitation, servicesOther than bending the environment to suit their construction needs, most buildersand developers used to spend little time considering their impact on the natural world. By the 1990s, however, governments began requesting that major projects include rehabilitation of the immediate land area affected by the construction. Trees were replanted, soil was cleaned and reused, and the future had arrived.In 1987, Thiess Contractors created an Environmental Services division to includewaste management and remediation services, which it had already been doing since 1984 for the Brisbane City Council. Next, Thiess acquired Waste Hawk waste management in Newcastle, then further waste management work was won in Shellharbour, Singleton, Illawarra, Redcliffe and the Blue Mountains.Remediation work had commenced in the mid-1980s, too, with work at the Rum Jungle Uranium Mine in the Northern Territory. In 1990, the new division won the site remediation work on the Little Manly Point gasworks, followed by BHP Port Kemblas steelworks wastewater treatment.But the biggest job for Environmental Services in that era was the clean-up and site preparation of Homebush Bay ahead of the Sydney 2000 Summer Olympics. Formally comprising abattoirs, brickworks, oil-, petroleum- and gasworksall of which had operated at a time without a sniff of regulation around dumpingthe job cemented Thiess rehabilitation skills, all under the watchful eyes of the Australian Olympic Committee and the federal government. It was the start of big things to come.To focus the efforts of the Environmental Services division (now called Thiess Services), the waste management component was sold off in 2012, giving space for remediation, rehabilitation, utilities and telecommunication to thrive. Since moving Thiess Services into Ventia in 2015 (which is ASX-listed today), environmental management andrehabilitation has again become important to Thiess in pursuit of a sustainablefuture for mining. Thiess launched Thiess Rehabilitation in 2022.74'
