Sydney Fish Market demolition in progress

Sydney Fish Market Early Works Demolition Package

Glebe, NSW
Hansen Yunken
7 months
Completed 2021


The Early Works required Liberty Industrial to demolish all the wharf structures, sub-structure and piles, redundant land-based structures including substations, office buildings and a redundant coal loader.


  • Neighbouring stakeholders included a school, residential dwellings, commercial buildings, recreational users of parklands and waters and the existing Sydney Fish Market - a bustling tourist hub.
  • The Hanson Wharf was a 60-year- old concrete deck supported by deteriorating timber beams and headstocks that required progressive wire sawing and lifting for removal.
  • The presence of asbestos and hazardous materials such as lead- based paints.
  • A restricted workspace with only 18m of land available for plant and equipment.

Robust Solutions/Exceptional Outcomes

Robust solutions

  • The Hanson wharf was demolished by working from the deck itself, systematically cutting the deck panels with concrete road saws, lifting the panels to expose the supporting beams and headstocks and then removing these with our 38t excavators.
  • The Finger Wharf piles were demolished using a 35t crane barge and a custom-built design system to progressively deload the concrete deck. This limited personnel exposure of the uncontrolled release of energy while separating the concrete blocks.
  • A land-based 250t crawler crane was used to cut the Pre-Cast Whard in manageable sections using concrete road saws and then progressively lifted out.
  • The piles were extracted using either direct line pulling or line pulling combined with a vibratory hammer/ clamping system.
  • Management plans were developed to control noise levels, manage work hours, traffic and stakeholder relations.
  • An environmental monitoring program tracked day-to-day noise, vibration, dust and water quality sampled from multiple locations outside the site.


Exceptional outcomes

  • More than 95% of all demolished materials were recycled, including approximately 9000t of concrete, brick, steel and hardwood timber.
  • Our safe, reliable and affordable solution allowed the project to be completed on schedule despite various challenges.
