Thesis ConclusionsRedesign of Student Health CenterPost-tensioned floor systemConcrete columnsShear wallsFoundationsCost/Schedule impactsShading SystemsQuestionsNew concrete building appears to work well and be more cost effective than steelDownside in scheduleHave to look into program that needs space

Learned the ins and outs of two computer programs

Shading systems viable to reduce need for fabric shading
