Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Precast Concrete Panel • Maintain Architectural Appearance • Variety of finishes and colors • Thermal Efficiency • Add rigid insulation to precast assembly • Maintenance • Durable • Cost efficient • Resistant to moisture.

  11. Thirty year study period Exterior façade area 23,000 SF Maintain insulation value of R-20 ASTM Standard Practice for Measuring Life Cycle Costs of Buildings and Building Systems Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Life Cycle Cost Analysis

  12. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System EIFS Installation Cost

  13. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Precast Installation Cost

  14. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Projected Maintenance Costs

  15. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Life Cycle Cost • Installation • EIFS - $344,761 • Precast - $275,377 • Maintenance • EIFS - $18,437 • Precast - $28,262 • Total Life Cycle Cost • EIFS - $363,198 • Precast - $303,639

  16. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Structural Impact • Typical Structural Frame • Bays 24’-0” x 19’-9”/19’-5” • Panel Size • 24’-0” x 7’-3”

  17. Tributary area = 242 SF Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Structural Impact • Calculation of Additional Loading

  18. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Structural Impact

  19. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Structural Impact • Design Load Increase • 13,777 pounds per bay; 8% increase • Original Perimeter Columns • W12X45 • Design Load Capacity = 350 kips • Resized Perimeter Columns • W12X50 • Design Load Capacity = 393 kips; 12.3% increase • Increased Steel • 30 Perimeter columns, each 38 ft. in length • Increase of 5 plf = 2.85 tons => $4,047.

  20. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Schedule Analysis • EIFS – Fork lift

  21. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Schedule Analysis • Precast – Crane

  22. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Cladding System Cladding System Summary • Use of Precast Concrete Panel System • First Cost Savings = $69,384 • 30-year Life Cycle Cost Savings = $59,559 • Increased Structural Steel = $4,047 • Overall Cost Savings • $55,512 • 16% savings on exterior cladding budget • 0.5% savings on project estimated cost • Increased project schedule 10 days

  23. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Presentation Outline Presentation Outline • Project Description • Cladding System • Mechanical System • Green Building • Summary & Conclusions

  24. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Project Description Original Mechanical System • Dedicated outdoor air system with parallel radiant panel system • Ventilation system – temperature control, air quality, and latent (moisture) load • Radiant panels address remainder of sensible load (temperature)

  25. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Mechanical System Mechanical System Redesign • Original Design • Estimated Cost = $1,500,000 • Did not consider structural effects of locating boiler and chiller on roof – additional $200,000. • Revised Estimated Cost = $1,700,000 • Redesign • 100% Outdoor air – geothermal system • Estimated Cost = $1,500,000

  26. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Mechanical System Mechanical System • 100% Outdoor Air – Geothermal System • Energy-efficient • Environmentally clean • Cost effective • Minitab Geothermal System • 40,000 lf of pipe – 100 wells @ 400 ft. each • 278 high-efficiency heat pumps • Air to air heat recovery system

  27. Geothermal Well Field Individual heat pumps for each space above the ceiling in the corridor. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Mechanical System Geothermal System

  28. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Mechanical System Geothermal System • Maintain energy efficiency • Maintain indoor air quality • Maintain service load requirements • Eliminate structural and architectural redesign • Cost Savings = $200,000
