1. Hotel Weight Estimation:
Assumptions:

Total floor area: 24,000 sqm24,000 \, \text{sqm}24,000sqm.

Average building weight per sqm: 4.5 kN/sqm4.5 \, \text{kN/sqm}4.5kN/sqm (standard for
reinforced concrete structures).
Total Building Weight (W1W_1W1):
W1=24,000 sqm×4.5 kN/sqm=108,000 kN.W_1 = 24,000 \, \text{sqm} \times 4.5 \, \text{kN/sqm}
= 108,000 \, \text{kN}.W1=24,000sqm×4.5kN/sqm=108,000kN.
2. Soil Weight Estimation (Displaced Volume):
Foundation Assumptions:

Foundation footprint: Approximate 2,000 sqm (estimated 10% of the lot area for a hotel).

Depth of foundation: 3 m3 \, \text{m}3m (common for buildings in reclamation areas).

Unit weight of soil: 18 kN/m318 \, \text{kN/m}^318kN/m3 (average for reclaimed soils).
Displaced Soil Weight (W2W_2W2):
W2=Foundation Area×Depth×Unit Weight of Soil.W_2 = \text{Foundation Area} \times
\text{Depth} \times \text{Unit Weight of Soil}.W2=Foundation Area×Depth×Unit Weight of Soil.
W2=2,000 sqm×3 m×18 kN/m3=108,000 kN.W_2 = 2,000 \, \text{sqm} \times 3 \, \text{m} \times
18 \, \text{kN/m}^3 = 108,000 \, \text{kN}.W2=2,000sqm×3m×18kN/m3=108,000kN.
