  2. Site conditions AEC AEC

  3. Functional spaces and relationship AEC AEC

  4. Dead Loads Lightweight Concrete Slab: 55 psf Steel Deck: 5 psf Partition Walls: 20 psf Finishes, Lights: 10 psf Ducts, Pipes: 5 psf Roofing System: 25 psf Live Loads Offices: 50 psf Classrooms: 40 psf Auditorium: 50 psf Corridors: 100 psf Snow: 50 psf (Altitude~2500 ft.) AEC Gravity Loads

  5. AEC Sample Gravity Load Path

  6. Wind Exposure B V33 = 70 mph Earthquake Zone 3 Type B Fault Zone AEC Lateral Loads

  7. AEC Sample Lateral Load Path

  8. Soil Stiff Sand Bearing Capacity: 5 ksf Low settlement Frost Depth: 4 ft. Foundation Wall footings at perimeter Column footings under interior columns Slab on Grade AEC Foundation Considerations

  9. Construction • Budget is reduced for 4% inflation over the next 14 years. • (2015 Budget = 2001 Budget x0.9614) • The money available for the building is further reduced by overhead and profit. AEC

  10. Redesign - design concept “soft fluid among stones – water among stones“ AEC

  11. Redesign - schematic layout AEC

  17. Eccentrically Braced Frame Efficient, ductile system Eliminates need to coordinate concrete and steel workers Shear Wall Ductile in combination with frame system Traditional, widely used Less expensive in general AEC Redesign - Structure

  18. Redesign - Construction Foundations Complete 7/1/15 Finishes Complete 5/25/16 Superstructure Complete 10/14/15 Building Closed In 1/6/16 AEC

  19. Redesign - Construction Total Budget: $2,842,260 Breakdown of Costs: AEC

  20. Redesign - Construction Construction Equipment • Largest crane pick is a 3 kip column • Hydraulic excavator for basement • Concrete will be placed with a pump AEC

  26. AEC Alternative 2 - Structure

  27. APP C E AEC Alternative 2 - Structure • Concept • Maximize floor-to-ceiling height • Thin slab on columns • Eliminate internal beams • Reduce finishing costs • Allow large windows

  28. Gravity System Flat Slab System Minimum allowable depth: 7 in. (probably greater) Post-tensioned slab Approximate depth: 8 in. Waffle slab over Auditorium Approximate total depth: 24.5 in. (4.5 in. top slab) 30” x 30” voids, 6”ribs @ 36” Slab Drop panel Column AEC Alternative 2 - Structure

  29. Lateral Load Systems Concrete Cast in Place SMRF Precast Concrete SMRF Shear Wall for redundancy Typical Member Sizes: Ext. Beam: 18x24 in. Ext. Column: 18x18 in. Int. Column: 12x12 in. AEC Alternative 2 - Structure

  30. AEC Alternative 2 - Structure • Sample Connection Details • Cast in Place SMRF • Precast sMRF post-tensioning mild steel bars (from pankow.com)

  31. Exterior Cladding Finished concrete (CIP or Precast) Saves material cost Concrete must be designed for thermal effects Precast stone cladding Adds cost for material and installation Lightweight materials Lower life-cycle costs (i.e. insulation) AEC Alternative 2 - Structure

  32. Roofing System and Skylight AEC Alternative 2 - Structure Wood truss with steel tension members

  33. Alternative 2 - Construction Building Closed in 12/16/15 Foundations Complete 6/24/15 Finishes Complete 6/1/16 Superstructure Complete 9/23/15 AEC
