How to Make a Prefabricated House Plan

The prefabricated house plan should be formulated by combining project requirements, technical specifications, and construction conditions, covering core aspects such as goal setting, construction deployment, process flow, and quality control. Details are as follows:

I. Clarify Project Objectives

Four major objectives—quality, safety, progress, and cost—need to be set. The quality objective requires a 100% pass rate for sub-projects and an excellent rate of ≥95% for key processes, in compliance with design documents and technical specifications. The safety objective aims to achieve 'zero deaths and zero serious injuries', with a minor injury rate of ≤3‰. The progress objective requires setting a total project duration and adopting a four-level progress control system (e.g., annual, quarterly, monthly, and weekly plans). The cost objective involves controlling the unit cost, reducing material waste through factory production, and optimizing resource allocation.

II. Overall Construction Deployment

1. Organizational Structure: Establish a project management department with technical, production, quality and safety, materials, and logistics teams, implementing matrix management and clarifying job responsibilities.
2. Key Route Planning: Proceed in the order of foundation construction → main structure installation → roofing works → completion acceptance, ensuring tight process衔接 (Note: '衔接' is translated as 'linkage' in context, but 'proceed' is used here to convey the sequential nature; a more literal translation could be 'ensuring tight process linkages').

III. Construction Preparation Phase

1. Site Preparation: Level the site to meet assembly requirements, set up temporary offices, warehouses, and material storage yards, and plan construction roads to ensure smooth traffic.
2. Personnel Preparation: Form a professional construction team (including project managers, technicians, quality inspectors, etc.), conduct technical training on prefabricated house construction, and strengthen safety and operational norms.
3. Material Preparation: Purchase prefabricated components (such as walls and floor slabs) that meet design standards, stock up on auxiliary materials like steel bars and cement, and verify quality certificates.
4. Drawing Review: Focus on reviewing the prefabricated component splitting plan, node connection details, and reserved hole locations to ensure design feasibility and construction convenience.

IV. Construction Process Flow

1. Foundation Construction: Level and compact the foundation, make foundation formwork, and pour concrete to ensure foundation stability.
2. Component Transportation and Storage: Use dedicated transportation tools to secure components and prevent damage; stack them on-site by specification and take moisture-proof and deformation-preventive measures.
3. Component Assembly: Install walls, roofs, and floor slabs in the designed order, using bolts or welding for fixation to ensure structural integrity.
4. Decoration Works: Complete interior wall, floor, and ceiling decoration; install exterior doors, windows, stairs, and other facilities, paying attention to detail handling and aesthetics.

V. Quality Control and Progress Management

1. Quality Control: Strictly inspect raw material quality, implement a 'three-inspection system' (self-inspection, mutual inspection, special inspection) during construction, and ensure concealed works are covered only after passing acceptance.
2. Progress Management: Break down the total project duration into phased objectives (e.g., 15 days for foundation construction, 30 days for assembly), and ensure timely completion through dynamic resource allocation adjustments.

VI. Cost Control Measures

Optimize the material procurement process to reduce waste; reasonably allocate labor to improve construction efficiency; promote factory production to lower losses, and adopt modular construction to minimize rework costs.
