1. Construction site management and data collection
Composition of site construction management:
Construction management is divided into three stages: 1, construction preparation 2, construction stage 3 and completion acceptance.
(a) the construction preparation:
1, technical preparation contract, project budget, construction organization design, and blue prints.the design.
2, site preparation, engineering positioning, pay-off and review, construction permit declaration, quality supervision declaration, temporary occupation of roads declaration, site civilized construction enclosure, overlay construction, materials, machines and tools organization comes into play.
3, the organization is ready to organize labor comes into play.
(1): Determine the construction, working procedure and overlapping sequence.
(2): Organize the balanced flow in sections and submit the operation plan.
( 3); Organize new workers to carry out safety education and assessment.
(II): Construction stage:
1: quality control of construction organization design, supervision and implementation of system measures, specifications, procedures and process standards, implementation of quality inspection and quality acceptance standards, inspection and acceptance of process handover, inspection and acceptance of concealed works, inspection and acceptance of water test for leakage prevention, change of project visa, quality control of materials entering the site, strengthening construction review, and organizing regular and irregular quality inspection of engineering quality.
2. Safety control Implement the "prevention first" safety production policy, control five major safety factors (people, materials, machinery, methods and environment), including: construction work arrangement, electricity consumption and fire safety, implement graded safety production responsibility system, implement safety production reward and punishment system and measures, implement safety production inspection system, and organize safety technical disclosure and safety education and study.
3. Schedule control According to the contract time limit for a project and the construction organization design, work out the construction schedule operation plan in stages, check the progress in time, adjust the plan in time, and coordinate the cooperation between civil engineering and professional construction.
4. Cost control: make economic visas in time, take measures to reduce costs, optimize progress, optimize labor force, strictly control the quantity and quality of materials entering the site, implement material distribution quota acquisition, strengthen construction setting-out audit, control quality in advance, reduce rework losses afterwards, master economic claims and visa claims skills, and reduce economic losses.
5. Civilized site capacity management
6. On-site materials and tools management includes: production tools (uniform distribution and recycling), on-site materials (classified stacking and coloring in the construction layout) and reusable materials (classified stacking).
(III): Completion acceptance stage
1: The compilation of technical data includes: construction log, change items, construction acceptance records, material test reports and quality inspection acceptance records. Data should be recorded, accumulated and sorted in time. (The technical data is the basis for Party A's inspection and settlement, which cannot be ignored. )
2. Check and accept the completed project, organize the acceptance and collection of the completed project, check and accept the imperfect project hand and tail left by the project before acceptance, and handle it in time to create conditions for the completion acceptance.
3. The project completion acceptance record (Interim Measures for the Administration of Completion Acceptance Record of Housing Construction Projects and Municipal Infrastructure Projects) stipulates that the construction unit shall submit the following materials when handling the project completion acceptance record:
(1): record form of project completion acceptance (record form of housing construction project and municipal infrastructure project completion acceptance) (II): report of project completion acceptance.
(3): Approval documents or permission documents issued by planning, bus fire protection and environmental protection departments according to laws and administrative regulations.
(4): the project quality guarantee signed by the construction unit;
(5): Other documents required by laws and regulations;
(6): Commercial housing should also submit residential quality guarantee and residential instruction manual.
4. Acceptance of completed projects
Second, the unit engineering construction technical data management
Section 1 General principles
The function of technical data of unit project construction;
1: It is an important basis to reflect the engineering quality and work quality.
2. It is a true record of the whole construction process of the unit project.
3. This is an important archive for the maintenance, expansion and update of the unit project in the future.
4. The unified management of technical data of construction enterprises is beneficial to the engineering quality inspection and filing.
Section 2 Classification of Construction Technical Data Content

Brief introduction to the unified standard of construction quality acceptance of intransitive verbs
The construction project is divided into 9 sub-projects: ① foundation and foundation engineering ② main structure ③ architectural decoration ④ building roof ⑧ building water supply and drainage and heating engineering ⑧ building electrical engineering ⑧ intelligent building ⑧ ventilation and air conditioning engineering ⑨ elevator installation engineering.
Construction engineering quality inspection is divided into: unit project (sub-unit project), division project (sub-division project) and sub-project inspection lot.
The quality acceptance of inspection lots, subdivisional works, divisional works and unit works shall be stipulated in procedures and organization: (1) The quality acceptance record of inspection lots shall be filled in by the professional quality inspector of the construction project, and the supervision engineer (the professional technical director of the construction unit) shall organize the professional quality inspector of the project for acceptance. (2) The quality of subdivisional work shall be checked and accepted by the supervision engineer (technical director of the project of the construction unit). (3) The project quality of the division (sub-division) shall be checked and accepted by the chief supervision engineer (technical director of the project of the construction unit). (4) When the unit (sub-unit) accepts the project, the construction unit shall fill in the "Completion Acceptance Record of the Project Quality of the Unit (sub-unit)", the acceptance conclusion shall be filled in by the supervision (construction) unit, and the comprehensive acceptance conclusion shall be agreed by all parties involved in the acceptance and filled in by the construction unit to assess whether the project quality meets the design and specification requirements and the overall quality level.
Unit project completion acceptance procedures:
The project completion acceptance shall be conducted by relevant experts such as survey, design, construction and supervision organized by the construction unit. (1) After the completion of the unit project, the construction unit will organize the inspection and evaluation by itself, and make a completion acceptance announcement to the construction unit. (2) After the construction unit receives the project acceptance report, the person in charge of the construction unit (project) shall organize the person in charge of the construction (subcontractor), design, supervision and other units (projects) to carry out the project acceptance of the unit (sub-unit).
Check the proprietary concepts of civil engineering specialty. If a sectional project needs multiple inspections and evaluations, then each inspection and evaluation is called an inspection lot. According to industry regulations, the inspection parts of each inspection lot must be exactly the same. The inspection lot only does inspection, not evaluation.
The inspection lot is the smallest unit of project acceptance, and it is the basis of quality acceptance of sub-projects and even the whole construction project; The quality of inspection lot shall be accepted according to the master control project and general project; The quality of the inspection lot mainly depends on the inspection results of the main control project and the general project; The inspection lot can be divided into layers, construction sections and deformation joints according to the needs of construction, quality control and professional acceptance (Article 4.0.6).
