What is the market unit price of bridge reinforcement, concrete, carpentry and various services? thank you

The prices of project settlement, carpentry, bricklaying and reinforcement vary from person to person and from place to place. Generally around 200 to 300.

Contracted materials: also known as contracted materials, it refers to a project contracting method in which the owner buys all materials by himself and finds a decoration company or a decoration team to carry out construction. Because of the variety and high price of materials, some people worry that others may buy materials on their behalf, so some decoration households adopt the decoration form of buying materials themselves and contracting only cleaners.
