In my view, Capitalism Lab is about letting the market economy works. One of the big parts of the modern economy is big government, infrastructure or development contract. The development team can consider:
1. instead of paying a fixed construction fee and immediately get an apartment, commercial building or whatever public buildings on the site; the construction go through tender project and construction stage.
2. for each type of building, different amount of construction materials must be delivered to the construction site.
3. the developer can either arrange and set up construction themselves or contract out the project by tender. The contractor must then buy or produce at their own cost the construction material and deliver them to the site, and get paid the contract sum.
4. construction material can be divided into grade A (quality > 80) grade B (qua. 50 - 80) and grade C (qua 30 -50), and some more expensive commercial building requires higher grade materials to be built.
5. the government can also give out service contract, IT contract or even military contract for tender and fulfilled by contractors.
6. worker or machine can be hired to finished the contruction.
