10. 10 A1: Initial Thoughts

11. 11 Brief constraints, site restrictions, site location, existing buildings, ground conditions, underground services/obstructions, foundation solutions, ground floor slab, retaining walls/basement, levels/building height, structural framing, structural grid, superstructure, stability system, movement joints, disproportionate collapse, erection sequence, environmental, programme constraints, aesthetics, economy, sustainability etc. A1: Initial Thoughts

12. 12 Functional framing Stability Load transfer Uplift forces Suitability of materials Movement joints Schemes Stone Use of excavated soil Uplift forces Miscellaneous Robustness Waterproofing Maintenance and inspection Environmental Archeological concerns Ground Conditions Foundation Strata Allowable bearing capacity Liquefaction Ground movement: subsidence Architectural Review Visually exposed rock/stone cladding Expression of joints Foundation Solution Gravity (precast or insitu ) Site issues Dredging Use of excavated soil Uplift forces Site access Crane positions Noise/vibration Existing structures Scouring River-exits Ship traffic Sheet pile wall around island corrosion A1: Initial Thoughts Site Close to Sea Wind forces, flooding of basement Chloride attack Shi impact Heavy equipment might cause settlement Stability of slopes,flooding

15. 15 Sump Pit: a temporary pit which is constructed to trap and filter water for pumping into a suitable discharge area. A1: Initial Thoughts

16. 16 A1: Initial Thoughts

17. 17 A1: Initial Thoughts

18. 18 A1: Initial Thoughts

19. 19 A1: Initial Thoughts

20. 20 A1: Initial Thoughts

21. 21 A1: Initial Thoughts Approximate dimensions of precast perimeter wall (m UNO)

22. 22 A1: Initial Thoughts

23. 23 A1: Initial Thoughts

24. 24 Initial Thoughts (RC floor) S. No Advantages Disadvantages 1 Watertight structurally integral protection. There can be uplift of floor due to underlying saturated soil. This can be overcome by providing soil anchors 2 Efficient lateral load transfer due to strong diaphragm action More excavation required as compared to other schemes. This is environmentally less sustainable solution 3 More construction cost due to an additional RC retaining wall at the shoreline

25. 25 Initial Thoughts

26. 26 Initial Thoughts (RC floor/Geomembrane) S. No Advantages Disadvantages 1 Lower construction cost as compared to the integrated flooring system Watertightness dependent on a continuous barrier of geomembrane 2 Less excavation required compared to Scheme 2. So environmentally more sustainable solution 3 The floor uplift issue is minimized as the underlying sand infill can dissipate the uplift forces

27. 27 Initial Thoughts (Joints)

28. 28 Initial Thoughts (Joints)

29. 29 A2: Assumptions Site (ground level, access, storage area), existing building (impact during work etc ), ground conditions (constant across the site, ground water, contamination etc ), column spacing restrictions, bracing/shear wall restrictions

30. 30 A3: Design Codes and Reference Material ACI 318-19 Design of Concrete Structures Nelson

31. 31 A4: Scheme Design Report Scheme Option 1: RC wall and base Description Vertical loads Lateral loads Other details Scheme sketches Scheme Option 2: Precast Concrete wall and RC slab Description Vertical loads Lateral loads Other details Scheme sketches

32. 32 A4: Scheme Design Report Load Cases Buoyancy/ uplift should also be considered

33. 33 A4: Scheme Design Report Load Path Load Case Description a Full of water b Self weight of slab c Soil uplift Load a Load b Load c water level
