Construction Scheme for Petrochemical Gas Station Space Frame Canopy

All steel components of this project shall be fabricated in a factory and transported to the construction site for assembly. All components and accessories shall be organized, planned, classified, numbered, and packaged strictly in accordance with the design drawings.

The foundation adopts reinforced concrete static pressure pile independent cap foundations. The superstructure is a steel space frame system. The fabrication and installation of the steel structure require high precision and strict quality control.

This construction scheme serves as a comprehensive technical guideline to direct project construction and management, ensuring that the project is completed with high quality, high efficiency, safety, and civilized construction standards.

To fully leverage the company's technical and management advantages, scientific construction organization will be adopted. A highly qualified project manager and technical management team will be appointed, and project-based management will be implemented.

The ISO 9001 Quality Management System will be strictly enforced. Through meticulous organization and scientific management, the project shall be completed with high quality and efficiency, strictly fulfilling contractual obligations and ensuring acceptance in compliance with quality standards.

Workload of steel structure fabrication and installation

Availability of labor resources and construction equipment

Extensive experience in similar steel structure projects

Reasonable construction technology and organization plan

Construction schedule management is a key control factor to ensure timely completion, rational resource allocation, and cost control.

Except for force majeure events, the company has sufficient management capability, technical strength, and construction experience to ensure completion of the project within the planned schedule.

Company leadership shall conduct periodic and random inspections to supervise project implementation and assist in resolving construction difficulties.

The site construction manager shall strictly control daily and periodic task execution. Daily tasks must be completed as scheduled, and the "Three-Week Rolling Plan" system shall be strictly implemented to prevent delays.

Prior to delivery, steel components shall be accompanied by the following documents:

Product quality certificates

Construction drawings and design documents

Quality certificates and re-test reports for steel materials, connection materials, and coatings

Component delivery and shipping list

All welding materials must be qualified products with valid quality certificates. Electrodes shall be inspected upon unpacking to ensure intact coating and rust-free welding cores.

Electrodes shall be issued and used as needed, and damaged, damp, rusted, or coating-defective electrodes shall be strictly prohibited.

Welding equipment shall be maintained in good working condition with reliable grounding. Welding platforms shall be firmly erected with proper safety protection.

Before welding, grooves shall be thoroughly cleaned to remove rust, moisture, oil, and debris.

The project technical director shall participate in establishing quality objectives, quality plans, and quality control measures, and shall supervise their implementation.

Strict compliance with relevant codes, standards, and specifications shall be enforced. Each construction process shall be inspected and accepted before proceeding to the next. Non-conforming processes must be rectified immediately until quality requirements are met.

Steel structure fabrication and installation consist of multiple levels, including work procedures, sub-items, sub-divisions, and the overall project.

Quality control shall be implemented throughout the entire process—from raw material inspection to final project acceptance—ensuring systematic control at every construction stage.

Zero major accidents

Elimination of fatal accidents

Minor injury rate below 1‰

Safety prevention shall be prioritized, and a "one-vote veto" system for safety issues shall be implemented.

Safety management shall focus on preventive measures, continuous supervision, and strict enforcement of safety responsibilities.

A civilized construction management group shall be established under the leadership of the project manager to organize and supervise civilized construction activities on site.

The group shall formulate site management measures and supervise their implementation to ensure orderly, safe, and clean construction operations.

Civilized construction management shall adopt a zone-based responsibility system, regular assessments, and reward-and-penalty mechanisms.

The company's standardized management team shall conduct inspections and evaluations. The project department shall organize weekly inspections led by the project manager.

Civilized construction reflects the professionalism of the construction team and is an integral part of safe production.

Offices, warehouses, and fabrication areas shall be arranged according to the general contractor's requirements, with clear separation between production and living areas.

Offices shall have unified furniture and display project regulations and management systems. Appropriate landscaping may be used to enhance the working environment.

Canteens shall comply with standardized site management requirements.

Warehouses, equipment, and materials shall be stored separately according to fire and explosion risk, placed on standardized shelves, labeled uniformly, and kept clean and orderly.

Designated personnel shall be responsible for sanitation in offices, warehouses, and fabrication areas.

A "clean-as-you-go" system shall be implemented, with each work team responsible for cleaning its own work area.

Site sanitation regulations shall be formulated and strictly enforced, with regular inspections conducted by the civilized construction management group.
