Prefabricated Panel House Construction Plan

The construction plan for prefabricated panel houses should cover five core aspects: construction preparation, construction techniques, quality control, scheduling, and cost control. Details are as follows:

I. Construction Preparation

1. Site Preparation: The site must be leveled to meet assembly requirements. Temporary office, storage, and material stacking areas should be set up, and construction roads should be kept clear.
2. Personnel Organization: Form a professional team including a project manager, technicians, and quality inspectors. Provide technical training on prefabricated component installation to all construction personnel to ensure standardized operations.
3. Material Procurement: Purchase prefabricated components that meet design standards (e.g., for "prestressed hollow slabs," ensure they are certified as national standard compliant, with no cracks or chipped corners, and dense concrete at both ends). Also, prepare auxiliary materials such as steel bars, cement, and sand.

II. Construction Techniques

1. Foundation Construction: The foundation must be leveled and compacted. After formwork is made, concrete is poured to ensure the foundation's bearing capacity meets design requirements.
2. Component Transportation and Storage: Use specialized transportation tools to prevent component damage. Stack components in designated areas in sequence on-site to minimize secondary handling.
3. Component Assembly:
   • Assemble walls, roofs, and floor slabs in the designed order, using bolts or welding for connections to ensure structural stability.
   • Set up a 15-20 cm wide cast-in-place strip at the joints of prefabricated panels and directly above load-bearing walls to "lock" the scattered panels into a whole, enhancing earthquake resistance and crack prevention.
4. Decoration Works: Complete interior decoration of walls, floors, and ceilings; install exterior doors, windows, and stairs to ensure both functionality and aesthetics.

III. Construction Quality Control

1. Raw Material Inspection: All materials must be accompanied by certification of conformity. Prefabricated components should undergo spot checks for strength and dimensional deviations.
2. Process Monitoring: Strictly adhere to process standards during construction, with a focus on inspecting connection nodes and the quality of cast-in-place strip pouring.
3. Concealed Work Acceptance: Conduct acceptance checks on concealed works such as foundations, steel bar tying, and embedded parts, and retain visual documentation.

IV. Construction Scheduling

The total construction period is approximately 85 days, with staged control as follows:

1. Foundation construction (15 days) → Component transportation and storage (5 days) → Assembly (20 days) → Decoration (30 days) → Acceptance (5 days).
2. Cross-operations should be implemented at each stage, such as starting interior pipeline embedding during the decoration phase to shorten the overall construction period.

V. Cost Control

1. Material Management: Accurately calculate material quantities to avoid waste from damaged prefabricated components. Implement a quota system for auxiliary materials.
2. Labor Optimization: Allocate personnel reasonably according to the construction sequence, such as increasing skilled workers during the assembly phase and using multiple shifts during decoration.
3. Scheduling and Cost Linkage: Avoid idle labor through scheduling to reduce machinery idle costs.

Key Tips: The construction of prefabricated panel houses must strictly follow the principle of "design before construction," with a focus on controlling component quality and connection nodes. The construction of cast-in-place strips is crucial for earthquake resistance and crack prevention and should be carried out by professional teams.
