Evidence-based improvements in delivery models

This framework showcases proven improvements to the infrastructure delivery process made by G20 governments and industry, categorised by six common themes. Select a theme to view challenges, suggested improvements, related case studies, and resources.

View challenges and improvements by theme

Meeting changing community expectations of infrastructure with regards to ethical use of materials and labour, sustainability, and inclusive growth.

Meeting these expectations creates greater and more enduring benefits from infrastructure delivery.

Use ethical sourcing of labour and materials to comply with the 2015 Modern Slavery Act. Develop material commodity sheets containing the ethical risks and issues associated with its sourcing or production, certified schemes covering their responsible procurement and any mitigation actions and outcomes. Produce the commodity sheets in collaboration with contractors and suppliers to ensure procured labour and materials meet ethical codes.

Case Studies:

  • Crossrail (UK) is being constructed to provide a high-frequency suburban passenger service crossing the city of London from west to east, by connecting two major railway lines. The project included a requirement in its Works Information that all project materials were to be procured in accordance with the Ethical Trading Initiative base code, representing an internationally recognised code of labour practice. In addition, Crossrail formed a working group with its contractors to plan and action ethical purchasing. The combination of the two benefited Crossrail’s reputation while fulfilling its legal obligations.

Plan and identify social value outcomes early in the project through greater understanding and engagement with local communities. Identify early local partners who can participate in the supply chain for the infrastructure project to ensure they have the capabilities (systems, labour, stock etc.) to meaningfully benefit from the infrastructure project.

Case Studies:

  • Cairo Metro (Egypt) identified how different stakeholders would be impacted by the project, included young people and vulnerable people. The creation of a stakeholder engagement plan, based on field surveys, and a resettlement action plan ensured vulnerable groups were not overlooked in the planning process. It created 3,000-4,000 skilled jobs during the construction phase. Many workers were previously unemployed youth (case study from the GI Hub Inclusive Infrastructure Reference Tool).
  • US Bank Stadium (USA) implemented a Targeted Business Program that set a goal of 11% and 9% of construction contracts to be awarded to women- and minority-owned Minnesota-based businesses respectively (case study from the GI Hub Inclusive Infrastructure Reference Tool).
  • I-495 Express Lanes (USA) construction contractor awarded USD490 million in work to disadvantaged enterprise and small, women- or minority-owned businesses. This was assisted by the Procuring Authority, which had a policy that prioritised these enterprises and business, who help train and prepare small businesses to participate in contract opportunities. Community consultation led to a revision of the project plans to include additional entry points at Tysons Corner, which is a regional employment centre (case study from the GI Hub PPP Contract Management Guidance).
  • El Metropolitano Bus Rapid Transit (Peru) consulted with communities surrounding the trunk road, including door-to-door surveys and the presentation of a draft map of the project to receive feedback and recommendations during the design process. This informed the design of feeder routes, and the construction of ‘stairs of solidarity’ for those with disabilities (case study from the GI Hub Inclusive Infrastructure Reference Tool).
