2.7 Million 6/01/16
3.4 Million 5/12/16

• Owners choice
• 2 Entrances
• Privacy/security good
• Concrete system
• Straightforward structure

Benefits

• Spiral stairs
• Concrete frame slab
• Better MEP floor depth

• Not risky for A
• Roof truss MEP intake
• Stream threats
• Skylight leaking

• Extended footprint
• Deep floor beams MEP
• Lack of vertical mech. path
• space

Performance architecture

• requirements that are not matched
• computer machines room closed to the instr. labs
• level of allowed noise for large classrooms
• privacy of student offices

• requirements, that are matched
• daylight for all classrooms, labs, offices
• -all classrooms have a views to river or
  mountains
• -privacy for offices
• security for administration and computer machines
