First, the coordination and management of project supervision in the construction stage

2) Management and coordination:

Coordination work should not only pay attention to technology, but also establish a perfect management system. Through management, the cooperation problems of various professions in construction will be reduced, and unified leadership with Party A, supervision engineer and project manager as the main body will be established, with special personnel under unified command to solve the coordination work of various construction units. As Party A, supervision engineer and project manager, we should first fully understand and master the working procedures and design requirements of various disciplines. Only in this way can it be possible to co-ordinate the construction teams of various disciplines and ensure that every link of the construction is in place in an orderly manner.

Establish a responsibility system for problems, and establish a responsibility system step by step from management to team.

Establish a reward and punishment system, and establish a reward and punishment system on the basis of the responsibility system to improve the sense of responsibility and enthusiasm of construction personnel.

Establish strict concealment acceptance and intermediate acceptance system. Concealed acceptance and intermediate acceptance are the keys to coordinated management. At this time, the work has entered the physical stage from the drawing stage, and the problems between various professions are more vivid and intuitive, and the problems are easier to find, and it is also the easiest to solve and remedy. Through careful inspection by various departments, problems can be reduced to a minimum.

3) Organization and coordination:

Establish a special coordination meeting system. During the construction period, Party A and the project manager shall organize regular coordination meetings to solve the coordination problems in the construction. For complex parts, special coordination meetings should be organized before construction, so that all professional teams can further clarify the construction sequence and responsibilities.

4. Summarize experiences and lessons in time.

As a supervision engineer, we should be good at constantly summing up experiences and lessons in our work. Common coordination problems in construction include: coordination between electrical parts and civil engineering; Coordination between water supply and drainage and building structure; The relationship between the appearance, function and structure of the building; The relationship between prefabricated components, embedded parts, decoration and structure, the characteristics and requirements of construction; Coordination between auxiliary professions, etc.

5. Improve the professional level and comprehensive quality of supervisors.

The quality of products is inseparable from the level and quality of employees. While doing a good job in management, it is necessary to strengthen the technical training and professional level of supervisors, as well as their understanding and mastery of new technology products. Cultivate the professionalism and meticulous work style of construction personnel, leaving no trivial matters and future troubles in the construction.

Second, the work of project supervision in controlling project cost

1. Reasonable investment control in the design stage.

(1), choose the most reasonable design scheme in the form of design bidding, urge the design unit to adopt advanced technology and reduce the project cost;

(2) Evaluate the general layout scheme and single design scheme of the initial expansion design, and select the most reasonable scheme through calculation, comparison and analysis of technical and economic indicators;

(3) Implement quota design.

2. Assist the owner to select the best contractor in the bidding stage.

(1) Strictly taking the approved design budget as the control target, it is an important work for the project supervisor in the bidding stage to prepare the construction bidding documents, draft the terms of the construction contract, make the bill of quantities and quantity description, and assist the owner to select the contractor through bidding.

(2) Insist on bidding to determine a reasonable contract price and strengthen the qualification examination of the construction team. The quality of the construction team will directly affect the quality and duration of the project and play a decisive role in the economic benefits of the project. At the same time, determine a reasonable project contract price. Insisting on bidding and determining a reasonable contract price will play a positive role in schedule control and settlement in the construction stage. Supervision work must meet the requirements of the contract, and must be within the scope of national laws and policies to ensure that the payment given by each project meets the requirements of the contract. In engineering construction activities, the supervision engineer is in a dominant position, and whether the monetary income and expenditure behavior of contractors and owners is accurate and reasonable depends on whether the engineering cost signed by the supervision engineer is fair. Contract management is the basis of control and coordination, and it is also an economic and legal means, so it is very important to enhance the awareness of contract management and improve the contract terms.

(3) Equipment cost and material cost account for about 70% of the total cost in the construction and installation project, and are the main components of the direct cost of the project. Therefore, in the process of supervision, we should not ignore this part, introduce competition mechanism, carry out equipment and materials bidding, ensure product quality and reduce project cost.

3. Strictly review the project settlement at the completion stage.

Third, the quality supervision of project supervision in the construction stage

1. Establish and improve the quality assurance system and strengthen contract management.

Once supervisors enter the project quality supervision, they should first check whether the quality management of the construction site of the construction unit is correct. 2. Quality monitoring should be advanced, and construction operation should be guided in advance.

(1), to check and control the quality of raw materials and semi-finished products required by the project, the construction unit is required to strengthen management in staffing, organization and management, testing procedures, methods and means, etc. , and defined the quality requirements and technical standards for materials. In view of the multi-source and multi-channel materials such as steel bars and cement, "double control" should be implemented for each batch of steel bars and cement entering the site (that is, there should be quality guarantee, certificate of approval and material re-examination report). Materials that have not been inspected are not allowed to be used in the project, and materials that fail to meet the requirements should leave in time. The quality inspection of welded semi-finished steel bars is the focus of supervision work. Combination of visual inspection and inspection. First, check the axial displacement, bending angle, cracks and pits from the appearance, and then randomly select welding specimens for testing, and then accept them after they are qualified. The detailed rules for quality supervision of concrete engineering materials, which are the most widely used in engineering and have the largest amount of work, require the construction unit to ensure that cement, sand, stone, water and additives meet the quality requirements. On the premise of the test report, it is necessary to check whether the mixture ratio of concrete is correct and check whether all kinds of measuring instruments and measuring tools are accurate and complete. Whether the construction scheme and procedure of pouring are feasible. If any process does not meet the requirements of specifications and standards, immediately notify the quality inspection personnel of the construction unit to organize rectification and management.

(2) Strengthen quality awareness and implement the "three inspections" system.

Before the project starts, the supervisor shall hold a quality meeting with the technical person in charge of the construction unit, the quality supervisor and the person in charge of the relevant engineering team to strengthen the awareness of quality management and make it clear that in the construction process, each working procedure must implement the "three inspections" system, which shall be signed and accepted by the full-time quality supervisor of the quality supervision department of the company. Then, after acceptance and signature by the supervisor, the next working procedure can be started. (3) Strictly check the signature and acceptance of concealed works, and put forward rectification to the construction unit in time if any quality hidden danger is found.

During the acceptance of concealed works, the construction unit is required to pass the self-inspection, and then the full-time quality inspector of the company will check and sign the grade, fill in the acceptance form and submit it to the supervisor. Then the supervision engineer shall organize the project professional quality (technology) person in charge of the construction unit for acceptance.

3, dynamic control, hands-on.

Quality control in the process of engineering construction is an important difference between site supervision and quality supervision departments. Comrades who don't know much about project supervision often think that the supervision engineer is just walking around the scene to check whether the project is carried out in accordance with drawings, specifications and standards when accepting. This often leads to some quality problems and even rework. We change static inspection into dynamic control in quality control. Mainly grasp the following aspects.

(1), strengthen management and supervise around the clock.

Every on-site supervision engineer is required to be "diligent": that is, he should always go to the site to understand the construction situation, read more construction drawings, and be familiar with which important parts are designed; Be diligent, always remember when you find problems, and record what problems you deal with; Hard-working, often go to the scene around; Carefully remind the construction team of the quality hidden dangers that are easy to check at any time, and make disclosure to the construction team at any time; Diligent, familiar with drawings, trying to ensure the quality of the project. In terms of working methods and depth, it is required to be "strict" (strictly in accordance with the requirements of construction specifications, strictly controlled), "accurate" (decisive and accurate in dealing with problems, based on data), "meticulous" (conscientious in work, meticulous in self-care) and "practical" (do one thing in person, check it in person, and deal with quality problems substantively. In the construction of important parts or parts with special process requirements, the supervision engineer should be on duty 24 hours a day, and handle the problems in time when found.

(2) Grasp the "first", "key" and "key" projects in the project.

According to the scale, engineering characteristics and technical requirements of the project, the project to be managed by the supervisor is determined from the actual needs. When pouring the first frame column, binding the first beam reinforcement, laying the first wall, painting the first wall, binding the first column, beam reinforcement and erecting the first formwork at the construction site, the supervision engineer will go to the site to check, recheck the axis and elevation, measure the dimensions of components and structures, and weigh supporting materials.

(3), on-site inspection, measurement inspection, speak with data.

The supervision engineer inspects and judges the engineering quality through the results and data of on-site inspection and on-site measurement, and evaluates the quality grade with the measured data. Notify the construction unit in writing in advance, and attach the measured data, so that the construction unit can't cover up the quality problems and deal with them hastily to avoid similar quality problems in the future.

4, after acceptance, timely processing quality problems.

(1), the final remedial measure in quality control is post-event acceptance. For the quality defects or major quality hidden dangers existing in the construction after acceptance, the chief supervision engineer will issue a work stoppage order in time, requiring the construction unit to stop work for rectification. And cooperate with relevant units to put forward solutions and deal with problems in time. So as to ensure the quality of the project and avoid unnecessary economic losses without affecting the progress of the project.

(2) For the same process of an important division project, draw a flow chart according to the existing construction technology and operation requirements, such as the flow chart of pouring column and beam slab concrete, and indicate the construction sequence, so as to analyze the causes of quality accidents during acceptance. If a quality accident or problem occurs afterwards, the supervision engineer will only deal with the quality problem substantively, and put forward reasonable and feasible treatment opinions or schemes in time, without emphasizing the cause of the accident. In this way, the construction unit and construction personnel are willing to get close to the supervision personnel, not afraid of medical treatment, expose the places neglected by the supervision engineer in time, and cooperate closely with the supervision party to improve the project quality.
