• Evidence of saltwater intrusion

• Elevation above mean sea level verified

2. Soil & Geotechnical Conditions

• Soil classification (Marine clay / Sandy fill / Reclaimed)

• Bearing capacity test conducted

• Liquefaction risk evaluated

• Groundwater table depth measured

• Evidence of soil erosion or scouring

3. Foundation & Structural Design

• Foundation type (Pile / Raft / Combined)
