| dc.description.abstract | Highways, bridges, office buildings, houses, etc. are typical large-scale infrastructure systems of physical facilities that must be planned, designed, built, operated, and maintained. In addition to physical requirements, they have complex and often farreaching interactions with the social, political, and economic systems they serve. Built facilities that have long service life times and large size represent a major commitment in terms of both capital expenditure and, equally importantly, social and political structures. | en_US |
