1. Establish a project supervision department with clear responsibilities.
The effect of water conservancy project supervision is closely related to the establishment of supervision department. A strong and perfect project supervision department requires capable personnel, high professional level, reasonable division of labor and clear responsibilities. Therefore, whether from the perspective of doing a good job in engineering supervision, or from the perspective of enhancing the sense of responsibility and mobilizing the enthusiasm of supervisors, how to make a reasonable division of labor within the supervision department and clarify everyone's post responsibilities is an important and worthy of serious study. Only when the division of labor is clear and the supervisors do their best can we give full play to the subjective initiative. At the same time, the supervision department assigns different work contents according to each person's different professional expertise, clarifies the responsibilities within the scope of work, makes up for their professional weaknesses, and keeps the overall supervision level of the supervision department at a high level to meet the needs of water conservancy project supervision.
2, the quality requirements of engineering construction for supervision personnel
2. 1 Higher professional quality
Engineering construction supervision has the characteristics of professionalism, practicality and strong application, and the effect of supervision depends on the professional level of supervisors to a certain extent. Therefore, supervisors are required not only to have high academic qualifications and solid professional and technical theories, but also to have knowledge of current policies and regulations, computer application, organization and management, to be hard-working and healthy, and to be compound talents in engineering construction.
2.2 Good professional ethics
Engineering construction supervision should take "honesty, law-abiding, justice and honesty" as the professional criterion, "justice, independence and autonomy" as the working principle, and carry out supervision work according to relevant laws and regulations of engineering construction and engineering acceptance norms, procedures and quality inspection standards. In the process of supervision, supervisors do not completely deal with "things", but more with "people". Without convincing ability, it is difficult to support and implement supervision instructions, suggestions, audit opinions and methods to deal with problems, and it is difficult for supervision to achieve the desired results. At the same time, supervisors must also have good ideological and moral character and professional ethics, adhere to a realistic, fair and equitable working attitude, and must not harm the interests of any party in the project construction.
2.3 keen insight
The main responsibility of project supervision is to ensure the quality and safety of the project and safeguard the interests of both parties to the contract. However, engineering quality and safety accidents often have no obvious warning, and some violations often appear in a hidden state, sometimes giving supervisors an illusion. Therefore, if the supervisor is not careful, has no foresight and keen insight into the problem, and fails to take timely measures to stop illegal activities, it will eventually lead to adverse consequences and bear unshirkable responsibilities. In the process of construction, due to man-made or construction machinery (equipment) failure, the use of inferior materials, cutting corners, etc. , will leave a hidden danger to the engineering quality and safety. If the supervisor can't find and deal with it in time, the responsibility can't escape. This requires supervisors not only to pre-control supervision at the macro level, but also to pay attention to every subtle link at the micro level, focusing on safety production and product quality control, and taking preventive measures in advance for "frequently-occurring diseases" and "common diseases" in engineering construction management, so as to nip in the bud.
2.4 Strong coordination ability
In order to coordinate the relationship between the two parties to the contract, supervisors should have certain social experience and practical experience in engineering construction besides contract management knowledge and experience. It is necessary to go deep into the construction site to find problems in time and accurately grasp the first-hand information of the project construction. According to the corresponding norms and standards and the legally binding contracts or agreements signed by the parties to the project construction, we should adhere to the principles of seeking truth from facts, equal consultation, fairness and reasonableness, coordinate the relations between all parties, and fully mobilize the enthusiasm of all parties, so as to facilitate the smooth progress of the project construction.
3. Quality control in the construction stage
3. 1 Quality control in construction preparation stage
Before the project starts, the project supervision department should strictly review the quality management system, technical management system and quality assurance system of the contractor's on-site project management organization to ensure that it can guarantee the construction quality of the project. The technical performance report provided by the contractor shall be reviewed for the construction machinery and equipment that has a significant impact on the project quality, and those that do not meet the quality requirements shall not be used. For the machinery and measuring instruments used in the construction process, the contractor is required to report the appraisal certificate of the relevant testing department and pay attention to its validity period. The application form for mobilization of engineering materials, components and equipment submitted by the contractor shall be accompanied by quality certification materials and mobilization quality inspection records for review and signature, and parallel inspection or witness sampling shall be conducted on the mobilization objects according to the proportion specified in the entrusted supervision contract or relevant engineering quality management documents. For the engineering materials, components and equipment that have not been accepted by the project supervisor or are unqualified, the supervisor shall refuse to sign, issue a supervision notice, and notify the contractor in writing to rectify within a time limit.
3.2 Quality Control in Construction Process Stage
In the stage of construction process, dynamic control is the main management method, supplemented by prevention in advance, and three links are mainly grasped: guidance in advance, inspection in the process and acceptance afterwards. Everything is based on data, everything is based on words, pre-control in advance, and dynamically control key parts and key processes. In the process of construction management, in addition to the quality control of "key parts", the whole process and all-round quality control of engineering construction should be realized. The project supervision department shall regularly inspect the measuring equipment directly affecting the contractor's engineering quality, organize the inspection of important raw materials and semi-finished products according to regulations, and organize the on-site supervision, inspection and acceptance of important sub-items, sub-projects and various concealed works. Review the field test (evaluation) report of new materials, new technologies and new processes, which can only be used for construction after examination and confirmation. In the process of construction, when the contractor adjusts, supplements or changes the approved construction organization design, it shall be reviewed by the supervision engineer and signed by the project supervision department. Project supervision department handles engineering changes. If it is an engineering change proposed by the design unit in view of the defects in the original design, a design change document shall be prepared. The engineering changes proposed by the construction unit or contractor shall be reviewed and approved by the supervision engineer organized by the project supervision department, and then handed over by the construction unit to the original design unit to prepare the design documents. The project supervision department shall hold regular meetings at the construction site to check and analyze the construction quality of the project, and put forward improvement measures in view of the existing quality problems.
3.3 Quality Control in Completion Acceptance Stage
The project supervision department shall inspect and accept the completed division, sub-project and unit project according to the quality evaluation standards and methods of the current national standard Code for Acceptance of Engineering Construction Quality; The supervision engineer shall review and conduct on-site inspection on the quality inspection and evaluation data of sub-projects submitted by the contractor, and sign after passing the inspection; For subdivisional work with use requirements, inspection and acceptance must be carried out after inspection, test or operation. At the same time, urge the contractor to reorganize the completion data, review the completion data and project quality report submitted by the contractor, put forward rectification requirements for the problems existing in the project quality and office data, and sign the completion acceptance after rectification.
4. Investment control in the construction stage
The key point of investment control is to confirm the engineering quantity, verify the engineering quantity of the changed project, handle the engineering claim and control the engineering investment within the contract scope within the scope authorized by the owner and based on the construction contract. In the construction stage, the supervision engineer should assist the owner to solve the problem of imperfect design in time, so as not to delay the construction period and claim compensation from the construction unit. According to the quality certificate, bill of quantities, technical specifications and design drawings, the quantities completed by the contractor shall be measured. Measurement items are all items in the bill of quantities, items specified in the contract documents and engineering change items. The supervisor is responsible for reviewing or directly obtaining the quantities completed by the contractor at the construction site, and issuing measurement vouchers. The chief supervision engineer's main work in investment control is to review and sign payment certificates, review and handle engineering changes, issue engineering change orders and handle claims.
The construction of water conservancy projects requires all parties involved in the construction to carry out the construction in strict accordance with the requirements of the specifications. The supervision engineer must pay more energy and effort than others with a high sense of responsibility, and coordinate and unify quality control, schedule control and investment control to ensure the smooth progress of the project.
