UNRESOLVED ISSUES AND NEW OPPORTUNITIES

Infrastructure Development and Rehabilitation

Status: New materials and technologies have made significant inroads in practice. However, little progress has been made in clearing the backlog of infrastructure needs. Life-cycle cost analyses are more refined and sophisticated, but still not widely embraced for selection of preferred alternatives. Sustainability considerations are becoming more important.

 

  • More discriminating, penetrating, and cost-effective methods for seeing through the ground

  • Better coordination between planners, designers, constructors, and users

  • Passive methods for ground improvement, including biostabilization

  • Regional databases and data models

  • Smart geosystems and adaptive management methods (using the observational method)

  • Biofilms for corrosion protection

  • Long-term durability of geosynthetic materials

  • Use of formal reliability and life-cycle cost analysis

  • Quantification and reduction of uncertainties

Critical Issues: Wider use of life-cycle cost analyses, including incorporation of sustainable development and other social values, improved modeling of environmental impacts of infrastructure development, rehabilitation of existing geofacilities, and enhanced durability of geoconstruction.
