From page 7...
... . In a survey conducted for NCHRP Synthesis 405: Utility Location and Highway Design, only 20% of the states reported involving utility personnel in the planning stage of a project.
From page 8...
... What does exist in the literature are descriptions of methodologies for selection-specific project elements such as pavement type. The Gransberg and Molenaar report, "Life-Cycle Cost Award Algorithms for Design/Build Highway Pavement Projects," focused on using life-cycle cost analysis in the use of a best value selection process in a DB environment (8)
From page 9...
... Some advances in technology and "tagging" of utilities offer promise, but widespread deployment is well into the future. Encouraging the use of subsurface utility engineering is seen as a strategy that can be combined with greater coordination and the use of emerging and existing technologies to avoid the impacts currently experienced with utility conflicts.
