since the implementation of the construction supervision system in 1988, it has played an important role in accelerating the development of china's engineering construction management in the direction of socialization and specialization, and promoting the improvement of engineering, construction management level and investment efficiency. construction supervision system and project legal person responsibility system, bidding system, contract management system, etc. together constitute an important management system in the field of engineering construction in china.
construction project management refers to the construction supervision unit entrusted by the construction unit, according to laws and regulations, engineering construction standards, investigation and design documents and contracts, in the construction phase of the project quality, cost, progress control, contract, information management, coordination of the relationship between the parties involved in the construction of the project, and to perform the legal responsibility of construction safety management service activities.
the construction unit (owner, project legal person) is the entrusted party of the project supervision task, and the engineering supervision unit is the entrusted party of the supervision task. engineering supervision unit is engaged in professional service activities within the scope of commissioning authorization of the construction unit. unlike the international general engineering consulting services, engineering supervision is a project construction management system with chinese characteristics. at present, engineering supervision is not only located in the construction stage, but also the laws and regulations give the responsibility of project quality and production safety management to engineering supervision units. the nature of construction supervision can be summarized as four aspects: service, science, independence and fairness.
ⅰ. service content
the main work content of construction project management is to control the quality, cost and progress target of construction project through contract management, information management and organization and coordination, and to fulfill the legal responsibility of construction safety management. patrol inspecting,parallel testing, key works supervision, sampling witness is the main way of construction project management.

ii. scope of services
1. general public buildings
office buildings, commercial and residential buildings and hotel buildings with construction floor area of less than 28 floors and 30,000 square meters for single project, including decoration works; industrial production plants and warehouses with span of less than 24m, such as frame and row frame structures (except light steel structures).
note: single project construction area of 30,000 square meters or less.
2. towering structure projects
for example, chimney, smoke pipe, power plant cooling tower, cool water tower, inverted cone shell water tower, umbrella water tower, silo, ash storage, grain silo, fertilizer plant granulation tower and cement plant cement warehouse, etc., the building height of 120m or less.
3. residential projects
single building project with less than 28 floors and the total construction area of the subject section is less than 120,000 square meters.
4. thermal power generation projects (single engine capacity of 300,000 kilowatts or less)
5. power transmission and transformation projects (below 330 kv)
6 .photovoltaic power generation project
7 .wind power generation project
what are the differences between construction project management and project management services?
(1) different service nature
construction project management is a compulsory system. the construction unit must not only undertake the project management tasks entrusted by the construction unit, but also the social responsibilities given by laws and regulations, such as the duties and obligations in production safety management. engineering project management services are entrusted in nature, and construction units will only entrust engineering project management units to assist them in implementing project management when their human resources are limited and their professionalism cannot meet the needs of engineering construction management.
(2) different scope of services
at present, construction project supervision is located in the project implementation stage, while engineering project management services can cover the whole process of project planning and decision making, construction implementation (design and construction).
(3) different service focus
although the engineering supervision unit also adopts planning, control and coordination methods to provide professional services for construction units, its central task is target control. engineering project management units can provide professional project management services for construction units at the project planning and decision-making stage, which can better reflect the importance of project planning and is more conducive to realizing the whole life cycle and whole process management of engineering projects.
what are the conditions required for a construction unit to apply for a construction permit?
(1) approval procedures for land use for construction works have been carried out.
(2) where a construction work planning permit should be obtained in accordance with the law, a construction work planning permit has been obtained.
(3) where demolition and relocation is required, its demolition and relocation progress is in line with the construction requirements.
(4) building construction enterprises have been identified.
(5) there are financial arrangements, construction drawings and technical information to meet the needs of construction.
(6) there are specific measures to ensure the quality and safety of the works.
what are the respective quality responsibilities and obligations of the parties stipulated in the regulations on quality management of construction works?
(1) quality responsibilities and obligations of construction units: contracting out of works, examination of construction drawing design documents, commissioning of supervision units, carrying out quality supervision procedures for works, making procurement in accordance with the requirements of contracts and design documents, commissioning design units to propose design plans for renovation works with changes in the main structure, and completion acceptance.
(2) quality responsibilities and obligations of survey and design units: undertake business within the scope of qualification, carry out design survey in accordance with the compulsory standards for engineering construction, provide survey results, provide design documents, carry out design descriptions and participate in the analysis of engineering quality accidents.
(3) quality responsibilities and obligations of construction units: contracting within the scope of qualification, being responsible for the construction quality of construction works and quality inspection.
(4) quality responsibilities and obligations of the construction supervision unit: to undertake business within the scope of qualification. in accordance with the laws, regulations, relevant technical standards, design documents and construction contract, supervise the construction quality on behalf of the construction unit and assume the responsibility for supervision of construction quality.
what are the guidelines for noa engineering supervision's business activities?
noa engineering supervision has always adhered to the principles of "trustworthiness, integrity, fairness and science" in its business activities.
