While historic preservation of campus architecture has become widely supported within the last generation, it has at the same time become more complicated. Ehrenkrantz and Eckstut have suggested a three part planning strategy. Part one: planners should gather basic informationon each campus building. Next each part of the building should be rated for preservation. 1 might mean a detail or space of great importance which should be carefully restored, while 5 might be an unimportant space which should be modernized to suit current needs. Part two: A phased plan should be develop which spans the next decade with proirities established and a clear sequence including cost estimates. Flexibility should be built into renovations and new construction as anticipation of further renovation. Part three: The next step is to identify athe means and methods weighing such as availability of materials and suitablility of today's program. If a preservation campaign is well planned it can be done well at the same cost of even under the cost of new construction, and will demonstrate the respect for history and culture embodied in the institution.
