Good morning, fellow crypto friends and Doro enthusiasts. My hard work before the holiday is coming to an end soon!

These days, I showed the steel structure model to the master. He said that after calculations, my two-story house used over 20 tons of steel. This amount is too much. Usually, a standard two-story house only requires 10-12 tons of steel. To reduce costs, I need to review and eliminate some unnecessary structures.

I roughly calculated that, based on the price of 1 ton of hot-rolled steel at 1500 AUD, I used an extra 10 tons of steel, which alone increased the steel material cost by 15,000 AUD.
Transforming steel coils into structural components and final assembly also incurs labor costs. Our company has 2 steel workers, each earning 400 AUD per day. Their efficiency in operating machines and welding is about 5-6 tons of steel per day. This means the workers need an additional two days to finish welding these over 20 tons of steel, costing 1,600 AUD in labor.

Just the steel materials and labor costs amount to an extra 16,600 AUD, not including the costs for installation parts, transportation, and other expenses needed for this additional steel. A conservative estimate suggests an extra expenditure of around 20,000+ AUD😉😉😉
