[00:00:00]The solution involved embedding thousands of kilometers of thin steel pipes throughout the dam's interior.

[00:00:06]Cold water circulated through these serpentine pipes after each concrete lift, carrying heat away from the core and preventing catastrophic thermal cracking. Each concrete column was limited to 15 m on a side and 1.5 m in height with a minimum curing period of 3 days between lifts. This block pour method transformed an impossible thermal problem into a methodical sequence of thousands of individual placement.
