What is supervision, control and management? Three major controls: quality control, schedule control and investment control;
Two management: information management and contract management;
Coordination: organization and coordination (that is, coordinating the differences between the owner and the constructor in the project).
With the acceleration of China's reform, opening up and modernization, supervision has been introduced into China as an international practice in order to connect with the international construction system. Although supervision is an international practice, there is no unified system in the world, which has formed the situation that "a hundred flowers blossom and a hundred schools of thought contend" in the international supervision industry today.
The notice of Ministry of Construction 1988 "Several Opinions on Carrying out the Pilot Work of Construction Supervision" points out that the guiding ideology of carrying out the pilot project of supervision is to reform the management system of construction projects and improve the investment benefit and construction level. Visible, built
The purpose of establishing supervision system is to solve the problems existing in the traditional construction project management mode in China (that is, the investment, progress and quality objectives are seriously out of control) and reform the old construction project management system. Obviously, regulation has been alienated in China.
Engineering supervision can be divided into: quality control, schedule control, investment control, contract management, information management and organization and coordination, "three controls, two pipes and one coordination". Quality control; Schedule control; Investment control; close
The same management; Information management; Organization and coordination.
What do the three civil controls of construction supervision mean? The three control steps of the supervision department, as well as the effects and experiences of the three controls,
It is a method to implement investment control, schedule control and quality control in the construction site.
Investment control mode: the application and approval of engineering quantity and change procedures have been completed.
Method of schedule control: the monthly schedule lags behind the supervision notice, and the monthly statistical completion schedule is compared with the planned schedule.
Quality control methods: on-site supervision, etc.
Effect of control: whether the contract content is successfully completed according to the planned construction period, how many excellent units are there, whether the project investment is completed within the contract, etc.
What is the key schedule control to realize the three major controls of construction supervision?
quality management
Investment management
What is the key point to realize the three major controls of construction supervision? It is the management core of the construction party. In order to achieve the established investment objectives, the management core of the construction stage is to ensure that the construction entity implements it from scratch according to the established time limit, budget and quality objectives. The management core of the construction party: carry out project construction management according to the agreement of the construction contract, and at the same time maximize the interests of the enterprise. The management core of the supervisor: according to the agreement in the supervision contract, supervise and manage the project construction process and maximize the interests of the enterprise.
What is the project supervision system 1? It is not a "project supervision system" but a "construction supervision system".
2. The Construction Law of People's Republic of China (PRC) stipulates: "The state promotes the supervision system of construction projects." "Construction project supervision shall, on behalf of the construction unit, supervise the project quality, construction period and construction funds of the contractor in accordance with laws, administrative regulations and relevant technical standards, design documents and construction project contracts." Thus, the state has legally defined the legal status of the supervision system.
How to do well three major controls for supervision engineer. This ... topic is very big, and the words to be written are very long. I suggest you read more books about supervision.
What is the principle of supervision investment control? LZ is happy. As a supervisor, you can control investment. In fact, the key point of investment control is that there is no key point. In practical work, the on-site professional supervision engineer only has the right to confirm, that is, the investment of the construction unit, and you only have the right to determine his authenticity. The director has the right to approve. For the quantity and price of the project, investment control can be carried out in accordance with the provisions of investment control, such as the determination of the final payment, and the facts should be respected when examining and approving. Fair, neither biased towards the project owner, nor unchanged; Bias to the construction unit; Science should also belong to his principles.
What are the control points of supervision work? A, survey supervision points

Third, the key points of reinforcement engineering supervision
1 material acceptance
1. 1 According to the rebar entry report provided by the steel ... contractor, check the rebar mark, heat number, manufacturer and factory certificate, and check whether the experimental report is complete and meets the requirements.
1.2 visual inspection: the construction site will be re-examined as required, and the supervisor will randomly take the re-examination. If there are cracks, scars and granular or flaky old rust on the surface of the steel bar, it will be judged as unqualified.
1.3 reinforcement test: after the appearance inspection of incoming reinforcement is qualified, it is necessary to carry out effectiveness inspection and witness sampling, with 60T as a batch, and less than 60T as a batch. When one of the test results is unqualified, double the number of specimens of the same batch of steel bars and do the mechanical efficiency test again. This batch of steel bars is judged as qualified; If one sample is still unqualified, it should be judged as unqualified steel. If the unqualified reinforcement cannot be used in the project, it should be reported to the superior and the chief supervision engineer for handling, and detailed records should be made.
2 steel processing
2. 1 Require the construction unit to be familiar with the drawings, and provide the supervision engineer with the processing scheme, sample processing, bill of materials processing and preparation. The listing system shall be implemented, and welders shall hold relevant certificates; When it is required to replace steel bars, it must be reported to the supervision engineer, and the design institute should agree, otherwise other steel bars must be replaced.
2.2 Cutting of reinforcement: It is required that the fracture of reinforcement should not be horseshoe-shaped or curved. The reinforcement length should be as accurate as possible, and the allowable deviation is 65438 00 mm. ..
2.3 Bending forming: When the steel bar is bent and formed, the shape must be correct, and there can be no warping and unevenness on the plane. Bending and hook of reinforcement shall meet the design and specification requirements.
2.4 Steel joint: The joint is an important link in the whole steel engineering, and the quality of the joint is guaranteed. Therefore, the form of reinforced joint should be carefully selected, and the position of reinforced joint should meet the design requirements and construction specifications, and witness sampling should be carried out. Welders must be trained and qualified before they can take up their posts. Before batch welding of steel bars, trial welding must be carried out according to the construction conditions, and batch welding can be carried out only after passing the test. The welding quality acceptance of steel bars shall be carried out in accordance with the relevant sections of the current welding quality acceptance specification. Check reinforcement before welding and during processing. Unqualified steel bars cannot enter the binding site.
2.5 Reinforcement stacking: After reinforcement is formed on site, it should be stacked within the radius of gyration of tower crane. The site should be hard and flat, and laid to prevent steel pollution and deformation. Molded steel bars with different diameters should be neatly stacked, and signs should be placed on site, which should be neat and clear for easy inquiry and use.
2.6 Before the installation of steel bar binding, it is required to pop up the position line sign, and draw the position line of double-layer steel bar, especially the position of the main reinforcement of hidden piles, hidden beams and doors and windows, which must be accurate and take anti-displacement measures; Mark the position line of floor reinforcement on the leveling layer; Mark the vertical reinforcement of the wall reinforcement; The floor reinforcement is marked on the membrane plate; Column stirrups are marked on four symmetrical vertical bars; The stirrup of the beam shall be marked on the mounting stud. The cushion block has enough strength to ensure the thickness of the protective layer of steel bar; After the steel bar binding is completed, the following aspects should be checked: according to the design drawings, check whether the steel grade, diameter, quantity and spacing of steel bars are correct, and pay special attention to the position of negative reinforcement; Whether the joint position and lap length meet the design and specification requirements; Whether the binding is firm and loose; Whether the protective layer of reinforcement meets the requirements.
