According to sources, AECOM was hired this month by the U.S. Government Treasury Department to select and analyze the 50 most economically significant transportation and water projects that are awaiting funding in the United States.

This service is understood to be part of the Obama Administration's policy to support private investment in infrastructure. The deal pipeline, to be prepared by AECOM in a period of six months, will include both public private partnerships (P3s) and public projects.

Sources said that ten percent of the projects must be water or wastewater-related and the list of 50 projects must be geographically spread to reflect regional needs.

The analysis of each project is to include an assessment of impediments to commencement, including funding and permitting, besides a detailed economic and social benefits analysis.
