 Classical Age Science 2 (Mathematics)
|
Buildings constructed faster (level 1) and have +10% hit points |
 Architecture |
150 150

 Gunpowder Age Science 3 (Chemistry)Construction |
Buildings constructed faster (level 2) and have +20% hit points |
 Engineering |
350 350
|
 Industrial Age Science 5 (Electricity)Architecture |
Buildings constructed faster (level 3) and have +30% hit points |
Note that the faster building construction time applies as soon as the technology research has been completed, which can cause buildings under construction to immediately gain building progress (and potentially be completed).
