  1. 2001 Final Presentation

  2. The Atlantic Team KIM Georgia TechArchitect HANS Georgia TechOwner PETER Georgia TechConstruction Manager YIP StanfordEngineer JARED Georgia TechConstruction Manager

  3. Our Site - Boston

  4. Site Location

  5. Site Constraints • Peninsula • Area of in-filled land • Winter snow

  6. Design Evaluation Alternative 1 Alternative 2 • Architect: • Concept fits local area • Less visually pleasing • Engineer: • Rigid diaphragm problem • Construction Managers: • Best budget • Architect: • Best looking building • Engineer: • Girders have deflection problem • Sloped roof helps snow load • Construction Managers: • Very constructable & best schedule

  7. Design Choice Alternative 2 • Best combination of strengths vs. weaknesses • Wood / Steel Hybrid • Combine the attractiveness / interest of 2W with the cost and schedule benefits of 2S • Keep wood exterior structure of 2W, but incorporate the steel interior structure of 2S

  8. Architectural Design Kim Ferraro

  9. Design Vision • Concepts • Box in a box • Simple, double structure • Advantageous use of sloped classroom and auditorium floors • Flow of light to below grade level • Exterior wood structure to gesture towards trees

  10. Auditorium Classrooms, seminar rooms, labs Student offices Faculty offices, facilities, administration Floor Plans

  11. Sections • Special Auditorium and Classroom Section • Typical Section

  12. 3D Model

  13. Structural Design Wai Yip Chan

  14. Engineering Constraints • Soil Properties • Compactable Soil • 4000 psf bearing capacity • Capacity, silt/clay and sand mixture • 20’ water table • Loading • Live Load 50 psf • Dead Load 70 psf • Wind Load 35 psf • Roof Load 28 psf

  15. Hybrid System Engineering Design 3 Timber Steel

  16. Evolution & Process TIE Evolution V Brace

  17. Inside Frame Plan Inside Frame Plan Typ Beam: W14X30 Typ Girder: W24X55 Typ Col: W12X40

  18. Prefab wood truss 2"X6“ @ 24” Column 12"DIA Knee brace 2"X6" Joist 2"X4" Outside Frame Plan Pre-fabricated wood truss with knee brace

  19. ETAB Model Large drift in the top floor Maximum moment at the mid-height of the timber columns

  20. Gravity Load Lateral Load Load Path Structure Load Path

  21. Typical Connection Wood / Steel Plate & Bolts Steel Bracing

  22. Jared Ford Peter Knobel Construction

  23. Site Layout • Crane:Arm Length = 106 ft • Construction Road:280 Feet Long • Trailers:Located at Entrance • Safety:Trailers & Toilets Not in Crane’s Radius

  24. Constructions Methods • Simultaneous Erection of Interior and Exterior Structure • Prefabrication of Roof Trusses • Work Sequence From the Center of the Building to the Two Outside Parts of the L-Shape -> Better Material Flow-> Simultaneous Work Opportunities

  25. Budget Information

  26. Cost Estimate

  27. Cost Summary Total Means Cost = $2,920,500

  28. Schedule

  29. Schedule Summary • Total Length of Construction: 160 work days = 33 weeks • Evaluation: Completion 5 weeks earlier than required

  30. Excavation Footings Foundation Basement Walls Backfill Interior Columns Exterior Columns Interior Beams Slabs Roof Trusses Roof Braces Roof Decking Structure Sequencing Graded Site

  31. Construction Sequencing Complete Building

  32. Truck Crane Excavator Telescopic Handler Steer Loader Equipment Selection

  33. Team Dynamics ANYBODYOUTTHERE?

  34. DISCUSSION Iteration Issues COMPROMISE THINKING • A-E: Location of Auditorium • E-C: Embedding of Exterior Columns in the Foundation • A-C: Size and Scale of Glass Storefront • A-E-C: Material Selection (Weather Constraints) • A-E-C: Roof Shape and Structure • A-E-C: Excavation Constraints (Infilled Land, Water) • A-Owner: Building Height • C-Owner: Budget and Schedule CHANGE DECISION SOLUTION

  35. Team Process “This spring we not only worked more thoroughly but understood that every detailed decision in one discipline in turn impacted the other two disciplines...Continuously iterating as we proceeded with the project” “The process can be frustrating. We should always bear in mind that the other parties are not our enemies. We have the same goal, to design the building. Don’t let it get too personal, use the communication tools provided in this class, and then less frustration will occur.” “After getting to know the other’s expectations and concerns better, we handled all issues much easier, faster and more effective during the spring quarter by anticipating everybody’s opinions and, therefore, avoiding problems even before they arose.”

  36. Lessons Learned • Cross-Discipline Knowledge • Objectives and Concerns • Different and Discipline-Based Development Habits • Teamwork • Efficiency • Reliability • Organization / Work Habits • Technology • New Hardware & Software • More Effective Use
