A labor earning 300 per day is possible !!!
Each day in work I realize that with better tools and technique things can be done much efficient way. For example to build a concrete roof (known as ‘lenter’), it involves shuttering work – to make a temporary “roofing” on top of which the concrete is poured. The traditional way of doing it, I have been seeing here and before also in my native, involves using bricks, wood timber, wood sheet, iron pipe, cement, sand, soil etc.. The cement and sand is used only to make the temporary “roofing”, which is destroyed after the concrete slab is built.
