Chernobyl: Building the New Chernobyl Sarcophagus

The video tutorial explains the design and construction of a large trellis structure, similar to the Eiffel Tower, using tubular steel elements. It covers the collaboration between engineers and subcontractors, the use of computer models for precision, and the assembly process involving pre-tensioned bolts. The tutorial also discusses the challenges of constructing a massive arch, the use of strand jacks for lifting, and the importance of safety and precision in the construction process.
