Steel is a sustainable construction material. The government’s sustainability strategy for the construction sector concluded that for long-term success, construction must be seen to be socially and environmentally responsible as well as economically viable. This demands prudent use of natural resources, avoiding pollution, reducing waste, energy efficient designs, effective management, staff health, safety and welfare, community relations, project quality, delivery, productivity and profitability. Though re-cycling and re-use are essential to minimise the energy used and the environmental impact of producing steel, sustainability benefits can be magnified by good design. Long-span structures promote adaptation and re-use.
The objective of the Steel Construction Sustainability Charter is to develop steel as a sustainable form of construction in terms of economic viability, social progress and environmental responsibility. Sustainability Charter members are required to make a formal declaration to:
The adoption of CAD/CAM and new fabrication technology has improved productivity, reduced waste and enhanced competitiveness. It has assisted the move to off-site manufacture giving better quality and fewer defects. Modular technologies and the emphasis on off-site fabrication have reduced risks and improved the health and safety of the workforce. They contribute to the development of communities, based on a stable workforce, better working conditions and training opportunities, rather than on itinerant workers. In addition, factory-based work is more easily controlled and has less adverse impact on its environment than comparable on-site activities.
