7. Design Complexity
• The construction was to take place over an existing mine, thus requiring complicated
foundations.
• The design had to be built in difficult conditions e.g. a hydropower station
8. Degree of Innovation
• New generation design
• Unusual site conditions requiring innovative solutions e.g. large wind forces, chemical nature
of soil and soil contamination
9. Environmental Impact
• Contamination e.g. nuclear power station, Incinerator
• Noise pollution e.g. airports
• Impact on wildlife e.g. new road through protected area
