**Chimney Beautification and Anti-Corrosion Construction Plan**
**1. Project Overview**
This project involves the beautification and anti-corrosion treatment of a 150-meter-high chimney and a 100-meter cooling tower at a power plant. It is a high-rise construction project with significant height and complexity, requiring specialized techniques and experienced personnel. Our company has extensive theoretical knowledge and practical experience in such projects, ensuring the successful execution of this task.
Our team is composed of highly skilled professionals who are capable of managing both technical and managerial aspects of the project efficiently. We have a proven track record in similar high-altitude operations, which gives us confidence in meeting all project requirements.
**2. Construction Objectives**
2.1 **Time Goal**: The project will be completed within 35 sunny days, ensuring timely delivery without compromising quality.
2.2 **Quality Goal**: Achieve 100% acceptance rate for each segment, with an excellence rate of at least 95% and an engineering quality score of no less than 90%.
2.3 **Cost Goal**: Maintain high-quality standards while reducing costs by 17% through efficient management practices.
2.4 **Safety Goal**: Follow the principle of “safety first, prevention first,†aiming for less than 1.5‰ general accident frequency and zero fatalities.
2.5 **Environmental and Civilized Construction Goal**: Ensure environmental compliance, maintain a clean and organized site, and establish a professional image to meet municipal-level standards.
2.6 **Technological Advancement Goal**: This project will be recognized as a science and technology demonstration project, with a technological progress efficiency rate of 1.5‰.
2.7 **Service Goal**: Provide excellent service to the client throughout the construction process, ensuring satisfaction with the final outcome.
2.8 **Warranty and Maintenance**: The perfect rate under normal conditions is 90%, with a 5-year service life, 5% warranty period, and 3 years of retention.
**3. Construction Deployment**
3.1 **Main Construction Measures**:
- Use of no-foot high-altitude suspension work.
- Manual rust removal.
- Brushing using a roller, climbing ladders, and protective nets with dual protection on the platform base.
3.2 **Main Materials Used**:
- Paint: Enamel (or chlorosulfonated), epoxy zinc-rich, chlorosulfonated polyethylene, and thinner.
- Accessories: Drums, brushes, protective gear, spare parts, etc.
- Ropes: 18mm brown rope and wire rope.
**4. Main Construction Contents**
The construction process includes: tool preparation → manual descaling → first primer → second primer → first finish → second finish → painting the first color ring → painting the second color ring → acceptance.
Key tasks include maintenance and anti-corrosion painting of the chimney and cooling tower ladders, nets, and platforms, as well as painting a 50-meter color ring on the chimney.
**5. Technical Construction Measures**
5.1 **Construction Methods for Aerial Work**:
- When painting the color ring, the worker stands on a suspended platform secured with a 18mm brown rope, with a 16mm safety rope attached to the waist.
- When climbing ladders, nets, or platforms, workers must use double insurance buckles, with safety ropes fixed securely.
- All safety ropes and suspension ropes must be inspected regularly before and during use.
5.2 **Painting Techniques**:
- Surface rust is removed manually to reach Sa3 standard. The cleaning order follows a top-down approach.
- Coating is mainly done by brushing, with attention to safety, edge areas, and proper drying time between layers.
- Construction should be paused if weather conditions change abruptly, and resumed once stable.
5.3 **Concrete Chimney Mark Painting**:
- The chimney surface must be thoroughly cleaned to remove dust, oil, and inorganic salts before painting.
- The color ring is divided into red and white, totaling 50 meters.
- Paint must be mixed properly according to the manufacturer’s instructions before application.
**6. Safety and Management Measures**
6.1 **Project Schedule Assurance**: Set clear goals, assign responsibilities, and ensure smooth workflow to complete the project in 20 sunny days.
6.2 **Construction Order**: Follow the project plan closely, focus on key processes, and ensure all personnel understand their roles for timely completion.
**7. Quality and Civilized Construction Assurance**
7.1 Conduct pre-construction safety training and detailed planning.
7.2 Ensure strict adherence to technical specifications and quality control procedures.
7.3 Implement self-inspection, mutual inspection, and professional inspections to guarantee quality.
7.4 Maintain cleanliness, manage waste effectively, and follow all civilized construction regulations.
**8. Safety Measures**
8.1 **Lifting Safety**: Only trained personnel over 18 years old can perform work. No alcohol consumption before or during work.
8.2 **Equipment Inspection**: Check all ropes, harnesses, and pulleys before use. Replace any damaged equipment immediately.
8.3 **Work Discipline**: Follow all rules set by Party A, avoid disorderly behavior, and maintain professionalism.
8.4 **Worker Safety**: Ensure all workers are certified, avoid high winds, and strictly enforce safety protocols.
8.5 **Security Officer Responsibilities**: Monitor site safety, conduct regular inspections, and report any hazards promptly.
This comprehensive plan ensures that the chimney and cooling tower are not only protected from corrosion but also enhanced in appearance, meeting both functional and aesthetic standards.
