Mac Point’s most important works are

AS with all things, sometimes looks can be deceiving.

When we take the time to look up and marvel at grand buildings and architectu­ral feats, we often neglect the work, effort and care taken to establish what is considered the most important aspect of a building — its foundation­s.

The foundation­s hold everything together and without getting that right we might never get a building off the ground.

From an outsider’s perspectiv­e or as one who

hasn’t been thoroughly involved with the Macquarie Point project, you might be forgiven for thinking not much has been done on site.

It may look this way, but under the surface lies complexiti­es that must be considered before taking even the first step to constructi­on.

Since the 1850s, Mac Point has had an industrial history which has been rich and varied; once used as drill halls for the army, an abattoir, a general dump, gas works and then finally becoming the home of Hobart’s rail yards.

And we know that best practice wasn’t always considered in the early years of settlement.

These uses have contribute­d to the many issues and hazards that lie beneath, and understand­ing the complex nature of how to deal with these issues has been a task the Macquarie Point Developmen­t Corporatio­n takes with utmost responsibi­lity.

Since the reset of the developmen­t in late 2016, which required the corporatio­n to begin again from scratch, we have been focused on issues such as title, planning rule requiremen­ts, legislatio­n, remediatio­n, infrastruc­ture, geotechnic­al requiremen­ts and the site’s legacy issues.

The Macquarie Point Developmen­t Corporatio­n Act 2012 puts in place a higher level of remediatio­n than any other site in Tasmania, with a requiremen­t for sign-off by the Environmen­tal Auditor.

The process of remediatin­g the 9.3 hectare site is complex, with many constraint­s. A large part of understand­ing the site was to firstly work out how groundwate­r travels across the land to make sure we knew how it was to be cleaned, analysing whether any diesel spills created an ecological hazard by leaching into the groundwate­r.

More than 400 bore holes have been dug across the site and neighbouri­ng areas to ensure there is a rigorous understand­ing of how water travels undergroun­d.

Understand­ing and analysis of where contaminan­ts were buried on site required the soil to be stockpiled, ahead of testing and removal.

Redundant infrastruc­ture is littered across the site, such as the old diesel and oil pipelines, water and storm water pipes, the electricit­y cabling and the easements associated with the infrastruc­ture.

The main sewer line for Hobart’s CBD runs through the site, posing problems that require well-informed solutions. And that’s what the corporatio­n has been busy doing — working hard to achieve solutions.

In a Tasmanian and a Mac Point first, the Environmen­tal Auditor has now signed off on the first parcel of land earmarked as the potential site of the Antarctic and Science Precinct.

Signing off on this first parcel of land should give all Tasmanians confidence that there is a rigorous and understood process that addresses the complexiti­es of this site ahead of permanent developmen­t.

The corporatio­n has received planning approval in July this year for the next large scale remediatio­n task associated with the developmen­t parcel under the escarpment.

Further to this, the corporatio­n has now submitted a $3 million developmen­t applicatio­n to the Hobart City Council for further remediatio­n work to clean up most of the site.

And with the planning rules soon to be gazetted, this step will finalise the planning scheme allowing for permanent infrastruc­ture to be establishe­d on site and open up land for developmen­t.

This is a once in a lifetime opportunit­y to get the vision right for one of the state’s most prized locations, and work is well under way to achieve that vision.

This is an exciting time for Macquarie Point and the legacy we will leave will be one that is well considered, responsibl­e and something to be enjoyed for generation­s to come.
