A study comparing the cost of the solid, flat, hollow block \(HB\), and post\-tensioned \(PT\) slabs for 4, 6, and 8m spans was conducted using SAFE software. For each span length, the total quantities of concrete and steel bars were found and compared for 4 slabs. Then, the total cost of steel bars, concrete, blocks, tendons, and formwork was tabulated and compared."]
