1, EPC is the abbreviation of English Engineer, Procure and Construct. It means "design, procurement and construction" in Chinese, which is similar to general contracting. It generally refers to the project design, equipment procurement, transportation, insurance, civil engineering, installation, commissioning and trial operation, and finally the unit is handed over to the owner for commercial operation. The whole process is called general contracting. Design-procurement-construction, also known as turnkey project general contracting, means that the general contracting enterprise undertakes the design, procurement, construction and commissioning services of the project according to the contract, and is fully responsible for the quality, safety, construction period and cost of the contracted project.

2.BOT is the abbreviation of three English words, namely Build-Operate-Transfer. BOT refers to the franchise granted by the government to private enterprises (including foreign enterprises) through contracts for a certain period of time, allowing them to finance the construction and operation of specific public infrastructure, and allowing them to repay loans, recover investment and earn profits by charging users fees or selling products; After the concession period expires, the infrastructure will be handed over to the government free of charge.

3. In the EPC project, if A is the general contractor, then Party A, the design unit, the construction party and the equipment supplier are all the general contractors of A, and they all belong to Party B, and the supervision unit is Party C; In BOT project, for the successful bidder B, government A is the owner of B; For design units, constructors and equipment suppliers, the winning bidder B is the owner.

EPC general contracting mode has the following three basic advantages:

(1) Emphasize and give full play to the leading role of design in the whole project construction process. Emphasizing and exerting the leading role of design in the whole project construction process is conducive to the continuous optimization of the overall project construction plan.

(2) The contradiction between design, procurement and construction is effectively overcome, which is conducive to the reasonable connection of design, procurement and construction, effectively realizes the progress, cost and quality control of construction projects in line with the construction project contract, and ensures better investment benefits.

(three) the main responsibility for the quality of construction projects is clear, which is conducive to investigating the quality responsibility of the project and determining the person responsible for the quality of the project.

Advantages of BOT project:

( 1)? Save investment: For developers, the biggest advantage of BOT heating mode is to save investment in heating equipment such as boilers, reduce the pressure of equipment bidding, installation and construction, and realize the optimal configuration of systems and equipment.

(2)? Easy to manage: For property management, BOT can form the continuity of construction and operation, avoid the negative impact of heating, and turn the possible results of property management fees into predetermined quantitative indicators.

(III) Owner's experience: The owner will not pay for the maintenance of heating equipment while obtaining heating and sanitary hot water services on time and in good quality. The heating company will hand over the whole set of equipment to the owner free of charge after the expiration of the contract.

(d) Social benefits: Maximize the system to save energy and avoid energy waste.
