Third, the working methods and principles of the supervision department
The chief supervision engineer requires all professional supervision engineers to proceed from the reality of engineering construction projects and implement relevant policies as the principle, strictly fulfill the entrusted supervision contract of construction projects and conscientiously implement relevant standards and regulations. With high quality of engineering construction, reasonable investment, fast progress and ensuring safety as the control goal. Take "law-abiding, honesty, justice and science" as the industry standard. Carry out supervision work in an all-round way by means of prior guidance, in-process inspection and after-the-fact acceptance. At the same time, all supervision engineers strictly exercise the rights entrusted by the Construction Project Entrusted Supervision Contract in their work, and strictly supervise according to law with capable business knowledge, pragmatic and dedicated spirit, meticulous scientific attitude and fair and honest work style. In the work, the internal management of supervision is constantly strengthened, and the work experience is actively explored and summarized, so that the supervision work reflects its own scientificity and fairness.
In terms of owner's service, the supervision department will try its best to meet the owner's requirements within the supervision scope stipulated in the supervision contract, and strive to be the owner's staff and agent. In the management of contractors, the principle of combining "management" with "supervision, assistance and promotion" is adopted to carry out the work, and at the same time, the contractor is urged to implement total quality management to promote the level of engineering construction supervision to a new level.
Fourth, the performance of the supervision contract
1, safety and civilized construction
Supervise and urge construction enterprises to conscientiously implement the policy of "safety first, prevention first" and implement the current national laws and regulations on safety production and the rules, regulations and standards of the construction administrative department on safety production. Review the construction organization design prepared by the construction enterprise according to the engineering characteristics and targeted safety technical measures; In particular, we should pay attention to the review of professional work projects and special safety construction organization design schemes and measures prepared by construction enterprises. Supervise construction enterprises to carry out safety and hygiene for workers.
Production education and safety technical disclosure of partial projects. Check and supervise safety facilities, protective equipment and basic engineering, formwork engineering, scaffolding, vertical transportation, lifting, mechanical equipment, temporary electricity consumption, limb opening, aerial work, health first aid, etc. Check whether it conforms to the provisions of the corresponding safety technical specifications and standards, and whether the safety facilities and protective devices are professionally managed. Supervise and inspect construction enterprises to establish safety professional inspection, employee self-inspection and daily safety inspection systems, and order violators to stop operations. If any potential safety hazard is found, it shall be ordered to stop operation. Check the construction of buildings and street buildings, whether to use dense mesh safety net or other devices for shielding. The roads on the construction site are clear and there are traffic signs. Warning signs should be hung in dangerous areas and red lights should be set at night. Supervise and inspect the fire control work on the construction site, cold and antifreeze in winter, heatstroke prevention and cooling in summer, civilized construction, health and epidemic prevention, etc. Safe and civilized construction control target value: there is no safety accident in the whole construction process, and a civilized construction site is created.
2. Engineering quality control:
2. 1. The principle of project supervision department to control project quality:
(1) Quality control runs through the whole process of project construction, and the idea of quality first runs through every link of the whole process of project construction.
(2) The project supervision engineer adheres to the principle of quality control in the whole process, and checks not only the product quality, but also the work quality, process quality and intermediate product quality; It is necessary to control not only the quality acceptance of molded products, but also the engineering quality before and during construction.
(3) The engineering quality inspection and acceptance shall be carried out according to the design drawings, current construction specifications and quality evaluation standards, and the measured data shall prevail.
④ Adhere to people-oriented quality control in the whole process of quality control.
⑤ Adhere to the supervision mode of "strict control, active participation and enthusiastic service".
2.2 Project Supervision Department's measures for project quality control:
2.2. 1 Prior control:
A: First, review the technical qualifications of the construction unit (technical qualifications of the general contractor and subcontractors) to ensure that the construction unit and team have the technical ability and management level to complete the project and ensure its quality.
B: At the initial stage of construction, implement the total quality management method in the construction unit, assist the construction unit to establish and improve its quality assurance system, determine the quality objectives of the project, assist the construction unit to establish the quality management system and technical management system, and implement the responsibility system for managers of the project department.
C: Before starting construction, the construction unit is required to declare the construction organization design, special construction scheme and seasonal construction scheme, and fill in the application form for construction technical documents and submit it to the supervisor for approval. The project supervision engineer mainly examines whether the construction method and sequence are scientific and reasonable, and whether the technical measures to ensure the project quality are appropriate. Construction organization design, special construction scheme and seasonal construction scheme can only be carried out after being approved by the supervisor, otherwise, construction can not be carried out to prevent the phenomenon of unguided and disorderly construction.
D: Check and recheck the survey marks on the construction site, the positioning axis of the building and the elevation leveling points. It is required that the measuring tools used in the construction site must be tested by the statutory testing department, with a test report, and full-time surveyors should be set up at the site and hold relevant certificates.
E: Construction machinery and equipment (such as tower crane, scale, hoist, concrete pump, etc. ) has a significant impact on the quality of the project, it shall be reviewed and the technical performance report provided by the construction unit shall be rejected. Ensure the normal operation of machinery and equipment entering the site, so as to ensure the normal construction of the project from the construction machinery, and then ensure the construction quality of the project.
F: Check and control the quality of raw materials and semi-finished products required by the project. The quality of materials and products is the basis to ensure the engineering quality. All materials entering the site shall have product certificates or technical specifications; At the same time, the second interview and witness sampling shall be conducted according to relevant regulations; Materials without product certificate and unqualified re-examination shall not be used in the project.
2.2.2 Process control:
A: Assist the construction unit to improve the process control and bring all factors affecting the process quality into the management state. For example, slump is measured during concrete construction, quality certification documents (mainly the label and slump of concrete on the transport list), the temperature of concrete leaving the machine and the temperature of concrete entering the mould are measured during winter construction, and the quality control points are determined.
B: Every day, the supervision engineer will make a purposeful inspection and stand by, and inform the construction unit to make changes in time (verbally) when problems are found. When the next inspection finds that there is still no rectification, a supervision notice will be issued, requiring the construction unit to reply to the rectification results in writing, which will be reviewed and confirmed by the supervision personnel. On-site supervision of key parts On-site supervision First of all, prepare the on-site plan and define the location and procedures of on-site supervision.
C: Adhere to the "three inspection system", and the construction unit shall report to the supervision department on the basis of self-inspection, mutual inspection and professional inspection. If the content is unqualified, notify the construction unit to rectify and follow up, and the next working procedure can be carried out only after it is qualified.
D: Adhere to the system of regular supervision meeting: the chief supervision engineer of the project will preside over the regular on-site supervision meeting every month. To study and solve the problems of project quality, progress, materials, labor, equipment and construction methods, and put forward measures to implement the people and construction period. Through this effective system, the project quality will be fully controlled.
Summary of General Supervision Work 2 I. Overview of Supervision Work:
According to the requirements of the owner and the specific conditions of the fourth and fifth contract sections, our company established the "= = = = Office of Chief Supervision Engineer for Supervision Contract Section" in July of 20**. The director is 1 chief supervision engineer, 1 engineering minister, and is equipped with professional supervision engineers, supervisors and testers for roads, structures, surveying, testing and metrology. , set up various functional departments to carry out supervision work. There are 24 supervisors and 5 administrative assistants, a total of 29 people. After entering the construction site, according to the contract and the owner's work instruction to start construction on August 8, 20 10, I entered the site on June 6, 20 10, and quickly carried out on-site construction. On July 20th, the work of the Director's Office was basically carried out in an all-round way to meet the requirements of project supervision. At the same time, the director's office quickly organized supervisors. According to the requirements of relevant contract documents and technical specifications, combined with the characteristics of this project, the supervision plan and implementation rules of construction supervision are formulated in detail, the responsibilities and rights of supervisors at all levels are defined, and various supervision procedures, such as the use procedures of quality inspection sheets, file transfer procedures, various meeting systems, etc., are implemented, so that the supervision work is gradually on a procedural, standardized and standardized track.
Second, the project quality management:
In the whole process of construction supervision, the Director's Office strictly controls the construction in accordance with the established project quality objectives, strengthens quality education, improves the quality awareness of supervisors, and ensures that the whole project meets the standards of excellent projects in the completion acceptance.
(A) the supervision of the construction preparation stage
(1) Do a good job of guidance and coordination before construction; On the basis of carefully examining the design documents and the contractor's project progress plan (including the construction organization design), we put forward the questions or ambiguities about the design to the owner in time, and solved them through consultation with the design and relevant departments, thus avoiding the blindness of construction, trying to brainstorm and being foolproof, and achieving good economic and social effects.
(2) Acceptance of contractor's construction setting-out; According to the provisions of the contract, the Director's Office, together with the owner and design department, handed over the original datum points, datum lines, datum elevation orientations and materials to the contractor at the site, gave guidance to the contractor's bridge triangular control setting-out, base point encryption and indoor calculation review, and intervened in the review and audit work all the time until the final acceptance.
(3) Supervise and assist the contractor to establish a perfect quality assurance system; In accordance with the requirements of the contract and specifications, our bureau strictly examines the qualifications, construction management experience and professional technical level of the contractor's full-time quality inspection director and self-inspection professional and technical personnel, and the establishment and feasibility of self-inspection rules and regulations.
(4) Strictly control the quality of materials entering the site; Before ordering materials or commercial parts, the contractor is required to provide the manufacturer's product certificate and test report, and test the material samples in advance to clearly agree to purchase or not. At the same time, the materials required to be purchased must be sampled and tested in strict accordance with the specified batch and frequency, and the unqualified materials must be resolutely retired.
(5) Strictly examine and approve the contractor's standard test; Control the quality of on-site construction. The test professional supervision engineer urges the contractor to complete the standard test (on-site supervision and inspection by the test supervision engineer) before the start of construction, and submit the test report and test data to the central laboratory for re-inspection to determine whether the test parameters and indicators are correct.
(2) Quality supervision in the construction stage of the project
(1) Clarify the control points and strengthen the management of supervision procedures; According to the detailed rules for the implementation of supervision formulated by our bureau, and according to the technical characteristics, construction technology, quality standards and requirements of each sub-project, find out the factors affecting the quality of the project.
Key links and main factors, detailed formulation of various reports such as construction, inspection, testing, testing, measurement and summary of results data of each project, and intermediate submission procedures of each project. For example, earthwork subgrade filling technology: setting out, surface cleaning, rolling (before filling), elevation measurement, marking, filling, leveling, rolling, compactness detection, etc. Through the careful supervision, inspection, acceptance and comprehensive tracking of every quality link of every working procedure, we will resolutely rework defects, omissions, errors or quality hidden dangers, and eliminate quality hidden dangers in the bud.
(2) Mobilize the subjective initiative of the contractor's quality assurance system; A high-quality and beautiful project depends not only on the supervision, but also on the careful organization, standardized construction, standardization and programmed management of the construction unit. In each link of "supervision and assistance", the main function of supervision engineer is to supervise and check the normal operation and self-control ability of the quality assurance system of the construction unit. As long as the construction unit can take the initiative to control itself, do well in all important aspects of project quality control, act according to the requirements of design standards and specifications, find out the quality hidden dangers in the project construction in time, correct the bad operation methods, and dare to deal with the quality accidents that have occurred, the completion of the project quality supervision task can be ensured.
(3) Strictly implement quality standards to ensure quality from the source; During the implementation of supervision work, all the supervisors in the General Office can strictly implement the quality standards, insisting that no single project can be started without adequate preparation; Unauthorized construction drawings shall not be used; Without the consent of the owner or the design department, the design shall not be changed; Materials without inspection or unqualified inspection are not allowed to be used; It is not allowed to adopt the construction technology that has not been proved feasible by the test; If the previous procedure is not signed, the next procedure shall not be carried out; The project with incomplete inspection data or unqualified inspection data shall not be measured and paid.
(4) Strengthen on-site supervision to find and solve problems in time; The combination of standing by and inspection is an important means of on-site supervision. Especially for concealed works such as concrete pouring, foundation and abutment backfilling, and important parts and engineering parts prone to defects, we insist on full-process, all-round and all-weather on-site supervision to ensure that every link of engineering construction can be carried out in accordance with the construction method approved by the supervision engineer. For non-concealed projects, combined with on-site inspection, especially in the case of obvious contradiction between schedule and quality, supervisors insist on sticking to the construction site for 24 hours, find problems and solve them in time. For the sudden problems in construction, mandatory documents were issued in time to make them be rectified or reworked within a time limit, and good results were obtained.
(5) Speak with "data" and give full play to the role of supervision and sampling; Engineering is based on "data", which is the most basic criterion for our engineers and technicians, and it is also the criterion that supervision work must follow. Therefore, we insist that all the tests of main quality control indicators such as steel, cement, sand and gravel and various mixture ratios used in the construction site are completed by the supervision engineer, and the tests are used to guide the construction and control the quality of the project, which also provides a scientific basis for the quality evaluation of the construction supervision project.
Three. Measurement payment, project progress and contract management;
1, we should earnestly do a good job in the "five controls" supervision centered on quality monitoring. The Director's Office has organized supervisors to familiarize themselves with the contract terms, supervision specifications, technical specifications, construction drawings and the objectives and contents of quality monitoring in different forms and methods for many times, and then draw the project schedule management curve according to the approved overall construction organization design, overall schedule plan and total project cost for dynamic monitoring.
2. Our office strictly examines the ten-day and monthly progress plans of the contractors. Supervise the contractor to implement manpower, mechanical equipment, material supply, construction management measures, etc. Enter the site as planned, focus on verifying the contractor's ability to implement the plan and the rationality of the construction progress, point out the unreasonable parts of the plan, and put forward specific opinions and requirements for adjusting and modifying the plan.
3. Check and implement the monthly plan at any time, grasp the gap between the actual progress and the planned progress in time, and give instructions to adjust the corresponding plan. When we reasonably control the contractor's implementation progress, we do our best to ensure that the project payment meets the schedule requirements. When the progress of the project lags behind, timely urge the contractor to increase the investment of personnel and machinery and equipment according to the contract requirements and strengthen the measures to ensure quality. The director's office always adheres to the principle that progress obeys quality, and quality supervision runs through the whole process of construction management.
4, project progress, measurement and payment. The construction progress of the fourth contract section is seriously lagging behind. Mainly due to the contractor's failure to strictly fulfill the contract commitments, serious shortage of personnel and mechanical equipment, weak management, poor planning, improper arrangement and poor coordination. The General Director's Office has repeatedly asked the project management department to fulfill its contractual commitments and increase the investment in personnel and machinery and equipment, but the results have been minimal, and several approved working faces have not been constructed. This seriously affected the completion of the annual construction plan. In view of the current situation, the director's office urged the contractor to earnestly fulfill the contract commitments and ensure the completion of Guangming Expressway on schedule. In the fourth contract, the accumulated amount has been1.1.20 million yuan (no advance payment has occurred).
Four, safety and environmental protection supervision:
In order to strengthen the safety and environmental protection work, our department set up a safety and environmental protection leading group with Director Xu Xuefeng as the team leader and Wang Hongyu as the full-time safety and environmental protection officer, and formulated a safety emergency plan and signed a responsibility letter for safety production.
