economics drive the majority of decisions and practices in society. Slab Jacking construction is the cheapest and fastest way to put up such a tall building saving many millions of dollars. Hundreds of lift slap office buildings, apartments, and parking garages has been successfully built without incident prior to this disaster. The big advantage of erecting concrete buildings using lift slab construction is elimination of most form work and false work (false work is what failed in the 3rd story bridge disaster in the documentary), an especially important factor in areas where labor costs are high. Concrete floor construction at ground level is convenient and requires no shores, scaffolds or cranes. Slabs can be cast and protected easily during cold weather without expensive heating and rain/snow enclosures. This construction technique is still used today throughout the world. While you can't insure the construction of a 16 story building in the USA anymore, it works great for two story warehouses and parking garages. China and other places that find human life cheap use it all the time.
Thanks , you saved our structures study session!!!!
