Sincethekickoffmeeting,thedevelopmentofconceptualsiteandbuildingplanshavebeenaniterativeprocess. The team investigatedmultiple concepts to identify themost effective arrangement of the

programmaticelements.Sharingof space, separationofoperationsand response, separationofdirty

considered. Externally, campus presence,materiality, vehicle circulation, building access, public and

adjacencies of the building divisions were determined, the individual program elements were

incorporatedintotheselectedsite/buildinglayout. Usingtheoperationalspaceneedsassessmentasa
