Example of applications:

• Green Technology and Innovation for project management, e.g.
  • Rebar manufactured in electric furnaces instead of blast furnaces to reduce the carbon emissions during manufacturing.
• Digitisation of project management, e.g.
  • Online system for document circulation, to reduce paper use;
  • Digital platform for performance tracking, project benchmarking, material submission and method statement submission.

Low Cost applications:

• Application of Engineering Design/Alternative Construction Method, e.g.
  • Replacement of timber with steel for lift shafts;
  • Replacement of timber with aluminum for formworks;
  • Use of alternative designs to save materials;
  • Use of alternative designs to re-use metal modules for horizontal supports, and use bolt and nut installation instead of welding;
  • Application of engineering design to reduce the amount of excavated materials;
  • Application of engineering design to reduce the time for rock breaking;
  • Application of engineering design of method statement to use micro (2m) TBM to replace manual digging;
  • Large-scale bored piles instead of pre-bored minisockets, to save time;
  • Small TBM to replace open-cut to minimise ground air pollution and save time;
  • Trenchless technology to replace open-cut to minimise ground air pollution and save time;
  • Pre-cast concrete slabs for tunnels (ventilation ducts) to save time and minimise metal rebar consumption;
  • Alternative structural supports to reduce the excavation to reduce noise, C&D waste and CO2 emissions
• Application of BIM, e.g. for
  • permanent works, incl. stages of design, construction and as-fit works;
  • site work planning;
  • temporary works;
  • later MEP stage to avoid material clashing;
  • cash control in design and installation process.

Sustainability KPI:

• Percentage reduction in CO2 emissions (kg) from use of alternative construction methods, per project (%)
• Percentage reduction in materials used, by engineering design (%)
• Percentage of time gained in construction process, by engineering design (%)
• Percentage use of steel rebar manufactured in electric furnaces instead of blast furnaces (%)
