A simple explanation of how construction cost is estimated and what affects the final figure.
Understanding construction cost helps you plan and budget with confidence. Here is how engineers approach a construction cost estimate in Bangladesh.
The basic approach
Approximate cost is built area multiplied by a per-square-foot rate. Built area depends on your land size, ground coverage and the number of floors.
Factors that affect cost
- Structural system and foundation type
- Soil conditions
- Quality of materials and finishes
- Site location and access
Design fees
Engineering and design fees are usually charged per square foot or as a percentage of construction cost, and they protect you from far larger risks.
