  1. Mountain Ridge Project- final presentation - The making of Ridge University Engineering Building OwnerRegina Pau, Sunnyvale ArchitectKatrin Wender, Weimar EngineerMartha DelCampo, Stanford Construction ManagerKris Grotelueschen, Stanford APPrenticeGrace Yamamoto, Stanford AEC AEC

  2. Site conditions AEC AEC

  3. Winter Decision Matrix A E C $2.7 Million 6/01/16 $3.4 Million 5/12/16 • Owner’s 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 Draw- backs

  4. Functional spaces and relationship AEC AEC

  5. 3d view – design concept ...water is flowing among stones... ...sunlight - collected like rain in a lake in the mountains... AEC

  6. Key elements of design instr. labs student offices, large meeting space normal student offices seminar rooms auditorium entrance hall • layout floor #2 • south-north section with sunlight study AEC

  7. Layouts (schematic view) floor #1 basement mechanical computer storage restrooms auditorium large classr. small classr. instr. labs student - offices seminar r. faculty off. secretaries chair‘s off. senior admin floor #2 floor #3 AEC

  8. Entrance the fly brake box builds a relationship between the road and the building AEC

  9. Sight lines • floor #1 • line: road – entrance – auditorium  leads people into the building • sight lines to stairs • circulation AEC

  10. Floor #1 entrance hall with fly brake box (1.1, 1.0) auditorium (1.5) large classrooms (1.4, 1.6) small classrooms (1.7, 1.8) restrooms (1.2, 1.3) AEC

  11. Floor #2 pbl spaces with seminar rooms, student offices, round table space (2.7-2.22)greenhouse space (2.23)instructional labs (2.6, 2.24)small classrooms (2.28, 2.30)faculty offices (2.4, 2.5, 2.26, 2.27)storage (2.25) restrooms (2.2, 2.3) AEC

  12. Floor #3 administration (3.23-3.29)faculty offices(3.4-3.21)storage (3.18)gallery (3.10)faculty lounge (3.6)restrooms(3.2, 3.3)hallway (3.1, 3.22) AEC

  13. Facades east / north west / south east south / east east / north north AEC west

  14. Performance – architecture AEC

  15. Structural system AEC

  16. Structural system elements AEC • Concrete columns • Concrete shear walls – bearing and lateral • Post-tensioned slab • Steel and glass roof truss system

  17. Structural system – gravity loads AEC • Dead Loads • Lightweight Concrete Slab: • Avg. 100 psf • Partition Walls: 10 psf • Ducts, Lights, etc.: 5 psf • Cladding: 10 psf • Live Loads • Offices: 50 psf • Classrooms: 40 psf • Auditorium: 50 psf • Corridors: 100 psf • Snow: 50 psf • Avg. LL (by area): • 62.5 psf

  18. Structural system – load path AEC Gravity:

  19. Structural system – lateral loads AEC • Wind • Exposure B • V33 = 70 mph • Earthquake • Zone 3 • V = 638 kips

  20. Structural system – load path AEC Lateral: V V

  21. Structural system by floor AEC B 1 2 3

  22. Structural details AEC Column and Column Footing Detail:

  23. Structural details AEC Column at Slab:

  24. Structural details AEC Wall Detail:

  25. Slab design AEC Post-Tensioning cable layout, Floor 1 16 banded 11” deep center span 10 banded 9” deep side span 5 distributed, 10 over column lines

  26. Slab design AEC Post-Tensioning cable layout, Floor 2 16 banded 10 banded 5 distributed, 10 over column lines

  27. Slab design AEC Post-Tensioning cable layout, Floor 3 16 banded 10 banded 5 distributed, 10 over column lines

  28. Slab design AEC Post-Tensioning cable layout, Roof 10 banded 10 banded 5 distributed, 10 over column lines

  29. Slab deflections AEC 1 3 R 2 Thanks to KL&A for use of Floor software

  30. Structural system – foundation AEC • Soil • Stiff Sand • Bearing Capacity: 5 ksf • Low settlement • Frost Depth: 4 ft. • Foundation • Wall footings under shear and foundation walls: 3.5’w x 12”d • Column footings under columns: 8.5 ft2 x 2’d • Slab on Grade

  31. Structural model AEC SAP 2000 Model:

  32. Structural model AEC Mode 1: Mode 2: T = 0.0952 sec. Δmax = 1.65 in. T = 0.092 sec. Δmax = 2.18 in.

  33. HVAC system 3rd floor Vertical Shafts 2nd floor Air Intake Air Exhuast 1st floor Basement/Mechanical AEC

  34. HVAC diagram AEC

  35. Construction site layout 88t Hydraulic Mobile Crane Sub Trailers Site Parking Site Office Site Entrance Material Laydown AEC

  36. Construction sequence AEC

  37. Construction budget AEC

  38. Construction budget Foundations $245K Substructures $63K Superstructures $690K Exterior Closure $467K Roofing $48K Interior Construction $554K Conveying Systems $52K Mechanical $749K Electrical $330K Special Construction $99K Total $3,297K AEC

  39. Atrium-Architecture Basis • sunlight through the atrium is collected like rain in a lake in the mountains • sunlight flows through the trusses into rooms • atrium trusses are like trees on the mountain AEC A App

  40. Atrium-Truss System A E C $ AEC App

  41. Atrium-Truss Selection App E C AEC Three-Hinged Arch Truss • Problems • deflection • complex connections

  42. Atrium-Truss Constraints • Architectural height constraints A App • Stability of half-truss C 4’ span 8’ span 2.3’ height 30’ elev 20’ span between trusses 40’ base AEC • Repeated glass panel size, 4‘x5‘

  43. Atrium-Truss Details AEC • Anchor connection to slab • Bolt connection • Purlin detail • Column connection, no slab

  44. Atrium-Member Sizes AEC • Truss members • 2L 4x4x1/4 • Bolts • A325N ¾“ diameter • Purlins • 2L 3x5x1/2 • Columns • W 10x100

  45. A E C • Breaking Down Discipline Lines Learning Experience-What did we learn here • Computer • Necessity • New hardware & software • Meltdown flexibility • Communication • Be Clear & Listen • Asynchronous vs. Synchronous • Create clear sketches • Collaboration • 1 Goal • Act as one Team AEC AEC
