The project department established the guiding principle of "safe production and civilized construction" at the beginning of construction. According to the Standard for Safety Inspection of Building Construction (JGJ59-99) and the specific requirements of the Provincial Construction Department and the Municipal Safety Supervision Station, the project department has made comprehensive arrangements from the aspects of personnel organization, measures formulation and fund raising to ensure that the site meets the requirements of safe and civilized construction.
First, seven keys to ensure safe and civilized construction:
1. Leadership is the key to ensure safe production and civilized construction.
At first, the project department gave all-round education and guidance to the managers in terms of ideology, management organization and measures formulation and implementation, and established the guiding ideology of "safety and civilized construction must be managed in production management" and "safety and civilized construction is everyone's responsibility", so that the abstract management consciousness and specific management effect of the managers in all departments of the project department can reach a harmonious state, thus guiding the actual safety and civilized construction work according to local conditions and making it a reality.
2, to ensure safe production and civilized construction, management system, organization is the key.
In the case of mature management thoughts of project department managers, the project department established a safety and civilized construction management system with the project manager as the first responsible person, and established and improved a safety management organization with full-time and part-time safety and civilized builders as the line and members of each team as the net. It has achieved a clear division of labor, the responsibility lies with people, and everything is in charge. According to the actual situation of the construction site, perfect rules and regulations and related safety technical measures have been formulated, which provides a good foundation for safe production and civilized construction.
3. Hardware is the key to ensure safe production and civilized construction.
While paying attention to ideological construction, the project department also attaches great importance to the hardware construction of the construction site. Although the project funds are very tight, we still actively raise funds to ensure that the funds for on-site hardware construction are in place first. Only civilized walls, construction sites, kitchens, toilets, shower rooms, dormitories, ground hardening, white walls and other safety facilities have invested more than 70,000 yuan. In addition, safety protection articles such as double beds, gas stoves and fire extinguishers were purchased, which provided a good guarantee for the safety of workers.
4. Software is the key to ensure safe production and civilized construction.
The construction site constantly carries out safety production and civilized construction education and inspection for new workers. After the project started, our project department conducted three-level safety education and safety skills training for new entrants for many times, and formulated the assessment system. Those who fail the examination are not allowed to take up their posts. And ensure that each person has no less than 80 hours of education. In view of the actual problems in the construction site, we should educate the workers on "Five Grasps" and correcting violations, so as to keep the alarm bell ringing, completely overcome the psychology of being lucky and paralyzed, and observe the rules and discipline, and do not work illegally, hurt themselves, others or be hurt by others. In addition, adhere to professional inspection, regular inspection, regular inspection, seasonal and holiday safety inspection, timely predict, forecast and prevent unsafe factors, and timely eliminate potential safety hazards in the bud according to inspection information.
5. Standardized construction is the key to ensure safe production and civilized construction.
Because this project belongs to brick-concrete structure, the formwork is frequently used, and the risk factor is large when it is demolished. In order to reduce the risk factor in the construction process, the project department has established an application and approval system for formwork removal. The project department calculates according to the construction speed, the concrete strength growth rate (curing the concrete block under the same conditions, measuring the daily average temperature) and the design load, and then decides whether it can be demolished according to the calculation results. Then, according to the date of examination and approval, the project department will arrange the scope of work of other types of work, divide the danger warning zone of formwork removal, and designate a special person to be responsible for the warning until the formwork is removed and the neatly stacked position is cleaned up.
6. Safety education is the key to ensure safe production and civilized construction.
Team is the cell of the construction team, and it is the key factor to do a good job in safe production and civilized construction. Front-line workers have low cultural quality, poor consciousness and no awareness of safe and civilized construction. To this end, the project department uses the regular meeting time of the construction site and the practice activities of safety education before shift to educate workers on civilized construction in simple terms with the operating procedures and safety awareness of this type of work, and gradually improve their awareness of safe and civilized construction. Through effective propaganda means such as blackboard newspaper and safety information, the awareness and importance of safe production and civilized construction are publicized, so that the construction personnel can change their conscious safe and civilized construction actions into subconscious behaviors, and the civilized construction and safe production work on the construction site will always meet the standards.
7. Qi Xin's cooperation is the key to ensure safe production and civilized construction.
It is Qi Xin's concerted efforts, correct attitude, consistent goals and effective measures that can make the on-site construction personnel look energetic and energetic; In order to make the construction process conform to the rules and regulations, no illegal operation; Only in this way can the engineering quality, safety and civilized construction conditions be steadily improved and the construction environment be well protected.
