DUSEL Development Process: The Roadmap from Science & Engineering Plan to the Facility Description Lee Petersen CNA Consulting Engineers

Nov 2004 What is “infrastructure”? Traditional definition: –Grouping of science & engineering functions into modules –Sequence, expansion, reuse –Excavations, systems & services to support science But “infrastructure” also includes: –Site characteristics necessary for conducting science & engineering
