Biology Building renovation was able to move forward when the decision was made to build a new building, which will provide relocation space for some of the old building occupants to allow remodel of the old facilities in phases. The same thing occurred to allow moving ahead with the EB project. There is no one basic rule as to how projects come into being. FSG serves as the gate keeper and helps determine if projects move into planning or not based on others' assessments of funding probability and priority. We don't like to waste time on projects that have no chance of funding.
Many decisions are political as to what can be supported by the legislature.
