amount of labour
The specific price mainly depends on the length of the tunnel, that is, the size of the project and the geological conditions of the tunnel. This price is now a purely manual quotation in tunnel construction, and the specific price shall be subject to the bidding price of the construction unit and the company's guidance price. After all, the current engineering projects are basically low-priced bids, and it is also an inevitable choice for the construction unit to minimize various expenses.
♂? Constrained production price
If it is a single item, the binding production is generally 580 ~ one ton of 600 yuan and more than one ton of 750 yuan.
Contract machinery and equipment price
If it is contracted machinery and equipment, it may cost about 20~30 yuan per ton, depending on the engineering quantity.
Project contract price
There are many factors that affect the contract price of engineering projects, such as construction conditions and mechanical equipment. , can decide whether a ton is up or down 20~30 yuan.
