10. Project information management
Including: information flow system, the establishment of the information center planning, project management software selection and use of planning, information management implementation planning.
11. Analysis of technical and economic indicators
Including: planning indicators; analysis and evaluation of the level of planning indicators; implementation of difficult countermeasures. Planning indicators include total construction period, quality standards, cost standards, resource consumption indicators, other indicators (such as mechanization level)
II. Specification requirements for the preparation of a separate special program
Only the mandatory special program for safety programs:
For a certain scale, hazardous divisions, sub-projects, should be prepared separately for the safety of special construction programs:
1. Excavation depth of more than 5 m (including 5 m) of the pit, tank support and waterfalling works; or pit is not more than 5 m, but geological conditions And the surrounding environment is complex, groundwater in the pit above the bottom of the pit support and waterfalling project.
2. Excavation depth of more than 5 m (including 5 m) of the pit, slot earth excavation works.
3. All kinds of tools template works, including slipform, climbing mold, large template, etc.; horizontal concrete components template support system and special structural template works.
4. Temporary electricity works on site.
5. On-site external power protection works: underground power supply, gas supply, ventilation, pipelines and adjacent buildings
6. Scaffolding works: floor-standing steel pipe scaffolding with a height of more than 24 m; attached lifting scaffolding (including the whole lifting and sub-piece lifting); cantilevered scaffolding; gantry scaffolding; hanging scaffolding; hanging basket scaffolding; unloading platform.
7. tower crane, construction elevator and other special equipment installation and demolition works.
8. lifting and hoisting works;
9. manual, mechanical demolition or demolition works by blasting.
10. Other dangerous projects:
Construction of curtain wall installation;
Pre-stressing structural tensioning construction;
Large equipment installation construction;
Grid and cable membrane structure construction;
Construction of slopes over 6 m;
Adoption of new technologies, new techniques, new materials, may affect the quality and safety of construction works, the danger is greater. quality and safety of construction works, projects of greater danger, etc.
Three.
III. Special construction program must include elements:
Safety special construction program must be designed, calculated, detailed drawings, text description.
IV. Scaffolding special construction program The main contents of the construction program include:
Foundation treatment
Setting up requirements
Rod spacing and the location of the wall pieces set up
Connection method
Removal procedures
Technical measures to ensure safety
Construction details and node sample drawings
The scaffolding If the erection height exceeds the specification, corresponding calculation should be carried out
