Construction diary is an indispensable document in building construction materials. However, because the construction diary is not included in the project completion data, it is often ignored. In fact, a complete construction diary can guide or infer the future construction. Below, I will share with you the writing method of the site construction log, hoping to help you!
How to write a construction diary First of all, we should understand the requirements for filling in the construction diary:
1, the construction diary should be filled in according to the unit project.
2. Recording time: from commencement to completion acceptance.
3. Daily records are not allowed to be interrupted.
4. Records shall be timely, true and detailed. In case of personnel changes midway, handover procedures shall be handled to maintain the continuity and integrity of the construction diary. The construction diary shall be recorded by the foreman of the building number.
Second, make clear what should be recorded in the construction diary. The contents of the construction diary can be divided into five categories: basic contents, work contents, inspection contents, inspection contents and other contents.
First, the basic content:
1, date, week, weather, average temperature. The average temperature can be recorded as XX℃? XX℃, the weather was recorded in the morning and afternoon respectively.
2. Construction site. Name, axis, floor, etc. Division and subdivisional work should be clearly written on the construction site.
3, head of the operation attendance. Attendance must be recorded according to the division of labor, and the total number of workers must be recorded.
Second, the work content:
1, construction content and actual completion on that day.
2, the main content of the construction site meeting.
3. Inspection opinions and decisions of relevant leaders, competent departments or inspection teams on engineering construction technology, quality and safety.
4, the construction unit, supervision unit of engineering construction technology, quality requirements, opinions and implementation.
Third, check the content:
1, acceptance of concealed works. Concealed content, floor, axis, subdivisional work, acceptance personnel, acceptance conclusion, etc. It should be stipulated.
2. Manufacture of test block. The name, floor, axis and quantity of the test block group shall be specified.
3, material approach, inspection. The batch number, quantity, manufacturer and acceptance of the purchased materials shall be stated, and the inspection results shall be supplemented after inspection.
Four, check the content:
1. Quality inspection: quality inspection and treatment records of concrete pouring and molding, steel bar installation and welding, brick masonry, formwork removal, plastering, roof engineering, ground engineering and decoration engineering on that day; Records of concrete curing, dosage of mortar and concrete admixture; The causes and treatment methods of quality accidents, as well as the effect verification after quality accident treatment.
2. Safety inspection and handling of potential safety hazards (correction).
3, other inspection, such as civilized construction, field capacity and appearance management, etc.
Verb (abbreviation for verb) Other contents
1, design change notice, technical verification and implementation.
2, construction task disclosure, technical disclosure, safety technical disclosure.
3. Power cut, water cut and shutdown.
4, construction machinery failure and treatment.
5, winter rainy season construction preparation and implementation measures.
6. Promotion and application of special measures and construction methods, new technologies and new materials involved in construction.
Third, pay attention to some details during the filling process.
1. When writing, the handwriting must be neat and clear, and it is best to write in imitation of Song Dynasty or block letters.
2. The main construction contents of the day must correspond to the construction site.
3. Maintenance records should be detailed, including maintenance parts, maintenance methods, maintenance times, maintenance personnel and maintenance results.
4. Welding records should also be recorded in detail, including welding position and welding method (arc welding, electroslag pressure welding, lap double-sided welding, lap single-sided welding, etc. ), welding current, covered electrode (agent) brand and specification, welding personnel, welding quantity, inspection results, inspectors, etc.
5. Other inspection records must be specific and detailed, and cannot be generalized. Inspection records can be memorized in detail and can also replace construction records.
6, water, electricity must be recorded clearly start and end time, water, electricity is how to return a responsibility, whether to cause losses.
Requirements for filling in the construction log. The construction log is an important resume document of engineering construction technology, which should be filled out separately by unit or single project and included in the completion document. Several items shall not be mixed or cross-filled.
Second, the construction log by the project (point), head of the construction or technical director in accordance with the provisions, fill in the content day by day, not every other day, jump day or rest day; The handwriting is neat and clear, and shall not be altered; Blue-black or carbon ink pen should be used for writing, and no other ink or computer printing is allowed; ? Record? Columns should be filled in continuously, and blank lines, paragraphs and pages are not allowed; Where should I add? Remarks? Write it in the column, and where should I record the problem? Remarks? Used in the column? *? Identify and mark the page number of correction and verification records.
Three, the construction log records should be detailed properly, highlight the key points, focusing on the content related to the formation process of engineering quality, to ensure the traceability of engineering quality. Do not write anything that has nothing to do with engineering construction and quality formation.
Four, fill in the content should at least include:
1. Describe the basic situation of this project separately on the home page. It mainly includes design summary, main construction director, technical director, quality inspection engineer, supervision engineer, commencement and completion date, etc.
2. At the top of the construction log, the project location (mileage or location), date, climate, etc. Will be written.
3. According to the construction sequence, truthfully record the whole process of project formation:
(1) Project image progress (construction content).
(2) Hydrogeological conditions.
(3) Main construction methods.
(4) Construction content and quantity.
(5) Mechanical configuration and usage.
(6) staffing situation.
(7) Safety, quality, environmental protection and civilized construction
(8) Change the design.
(9) Advance geological forecast
(10) Tunnel monitoring and measurement.
(1 1) Inspection and acceptance of concealed works.
(12) Technical disclosure, construction scheme and survey lofting.
(13) sampling of materials and tests.
(14) safety, quality and technical education and training.
(15) The superior personnel checked and rectified.
4. The problems recorded in the construction log must be corrected and verified in order to solve the problems.
