Barrack Place is a next generation A-Grade workplace, being the most advanced building in its class in Sydney. Along with its 18 floors the precinct includes retail and food offerings with a laneway adjoining Clarence and Kent Streets, likening it to the popular Ash Lane (Ivy Precinct) and Melbourne Laneways.

Willow was appointed by Investa Property Group as the Digital Project Manager for the Design and Construction Phase of the project to manage the consultant and contract deliverables. Willow was also utilised by the contractor Built and subcontractors for the collection, validation and structuring of asset data to enable a smooth construction handover and transition the building into smart operations.

Willow understood what was required to enable the smart building features – a foundation built on structured, validated and appropriately tagged data. The Willow team managed the process successfully, so that the 3D models, static data and live data integrated to produce the WillowTwin™ platform – the operational Digital Twin.



WillowDigital™ Engineering has been engaged to:

  • Develop managed asset list and asset data requirements
  • Review digital progress towards the Digital Twin objectives
  • Oversight of contractor activities and compliance to requirements
  • Provide advice to Investa executive on contractor progress
  • Review verification of as-builts

WillowTwin™ has been engaged to:

  • Implement Twin Creator as part of the Completions process
  • Facilitate the asset database and completions tracking
  • Integrate live data with the digital twin (3D and asset data)
  • Provision of software solution for handover and operations


Investa Property Group has derived the following benefits:

  • Completeness of asset data and accuracy of as built information at practical completion
  • Insights into the building function and operations utilising WillowTwin™
