What we do

Modern technologies for digital heritage include 3D laser scanning; Photogrammetric 3D models of buildings, sites, and objects; and HBIM (historic building information modeling) software. 

Not all heritage can be physically retained and much has been lost. The use of modern digital technologies not only facilitates and improves conservation practices and processes, but also enables the creation of a digital database of heritage. The Unitec Digital Heritage Research Centre investigates how to:

  • Raise awareness and implement the utilisation of modern technologies for digital heritage in the related professions and sectors; architecture, heritage conservation, and government.
  • Improve education in the use of modern technologies for digital heritage.
  • Improve the implementation of modern technologies for digital heritage.

Benefits of digital scanning include:

  • Having a “digital heritage” made up of computer-based materials of enduring value, accessible to future generations.
  • A more strategic approach to heritage conservation can be developed so that the continuity of heritage buildings is maintained. For example, digital data better enables close monitoring of the rate of decay or damage to structures over time.
  • A digital library of information exists which can be used to remediate the building in the case of natural or other disasters. For example, digital data gives precise measurements that can be used to repair and preserve irreplaceable heritage sites.
  • Assists the new generation of architects and other professionals to learn about the importance of heritage protection and preservation and how to work collaboratively with local communities and agencies towards a common goal.
  • Digital data enables the creation of digital models and virtual tours, which allow remote access to inaccessible or dangerous areas from specialists nationally and across the world through virtual reality.
  • Retaining built heritage and adaptive reuse of buildings prevents established embodied energy in wholesale buildings and their materials from being sent to landfills, with climate change in mind. 
  • Technical data (Point Clouds and BIM) can be used to create interactive and online-based materials that can be shared with contractors on a global scale, minimising site visits and reducing contractor carbon footprint. 

Current research

The research centre is currently working on a leading-edge 3D-modelling exercise, capturing historical and heritage buildings. It exemplifies collaboration between education, community, and industry and sets a new bar for digital technologies in domestic conservation practice thought in architectural education institutions. The project involves the scanning (using LiDar and Photogrammetry technology) and 3D-modelling of ‘Building 1’ that was part of the Unitec Mt Albert campus. This heritage building was formerly Oakley or Carrington Hospital (originally known as a Lunatic Asylum of the ‘Whau’).

The project will assist the research centre in better understanding: 

  • What levels of understanding of Digital Heritage (tools, equipment, software) there is in our professionals/ architects/ heritage architects/cultural heritage experts overall?
  • What buildings (heritage buildings) should be prioritised to be digitally recorded?
  • How can the practice of dealing with heritage buildings in New Zealand be enhanced through the use of Modern Digital Technologies?
