On-site Installation of Prefabricated Houses

On-site installation of prefabricated houses is a modern construction method that combines the advantages of prefabricated buildings and on-site assembly. The process includes custom design, factory prefabrication, transportation to the site, and on-site assembly. Choosing a manufacturer that offers integrated services for on-site survey, design, and installation has significant advantages, but users also need to pay attention to relevant matters.

I. Advantages of Choosing an Integrated Service Manufacturer

1. Reduced Time Costs: Traditional house construction takes from six months to a year from design to completion, while the "factory prefabrication + on-site assembly" model of prefabricated houses significantly shortens the construction period. For example, an 80-square-meter self-occupied house in Tongzhou, Beijing, with a traditional brick-and-mortar structure, is estimated to take 8 months to complete, whereas with integrated services, it takes only 45 days, demonstrating a significant improvement in efficiency.
2. Cost Control: Prefabricated houses have advantages in terms of comprehensive costs, including materials, labor, and taxes. For example, in rural self-built houses in Beijing, the average construction cost per square meter for traditional methods was 1,800 yuan in 2023, while prefabricated houses can be controlled between 1,300 and 1,500 yuan. For a 100-square-meter house, traditional construction costs about 180,000 yuan, while prefabricated houses cost only about 130,000 yuan, representing a cost reduction of approximately 28%.
3. Seamless Service Integration: Integrated services avoid the issues of disconnection between design, production, and installation in "segmented services," such as discrepancies between drawings and actual conditions, component size deviations, and mismatched installation techniques. This ensures seamless integration across all stages, enhancing the quality and safety of the house.

II. Considerations for Users When Choosing Services

1. Verification of Service Provider Qualifications: Prioritize service providers with a good reputation and professional construction teams. Verify their reliability by reviewing past cases, customer reviews, and industry certifications.
2. Clarification of Time Milestones: Require the manufacturer to clearly specify standard timeframes for each stage—"survey, design, production, and installation"—in the contract. For example, providing three design options within 5 days after the survey, a factory prefabrication period not exceeding 20 days, and on-site installation not exceeding 15 days to avoid construction delays.
3. Confirmation of All-Inclusive Costs: In addition to the unit price, clarify whether the total cost includes hidden costs such as transportation fees, lifting fees, and foundation construction fees. Choosing an all-inclusive service can prevent budget overruns.
4. User Cooperation During Construction: During the house assembly process, users need to actively cooperate with the construction team, such as providing on-site access to water and electricity and assisting with foundation construction, to ensure the structural stability and safety of the house.
