DEEP BASEMENT IN DENSE URBAN CONDITION
Design Consideration:
- Depth of Excavation- Type of Soil- Water Table- Adjacent Structure / Site Constraints- Sequence of Works- Excavation Methodology- Construction Details

� Top-Down Construction
� Semi Top-Down Construction
TDC enables the superstructureand the underground structureto be built simultaneously
Semi TDC makes use of thestiff RC slab as struts, startingthe construction from theground to the bottom
Use of RC Slab as Struts
DAVYSUKAMTA & PARTNERS, Structural Engineers
Use of RC slab as strut gives the required
rigid support for the diaphragm wall
Work progressed simultaneously for the
basement and the super-structure, saving
construction time
Design MUST reflect the actual sequence of
work. DETAILING is tedious and complex
