Key Advantages of Using Prefabricated (Modular) Houses
Modular houses have obvious advantages over traditional cast-in-situ buildings, making them widely used in various fields around the world:
- High Construction Efficiency: All components are prefabricated in the factory, and on-site assembly only takes a short time, which can greatly shorten the construction period compared with traditional buildings. According to relevant data, modular construction can save more than 50% of the construction time compared with traditional methods.
- Flexible and Detachable: As detachable houses, Dongji modular houses can be disassembled, moved and reused multiple times, which is suitable for temporary use scenarios such as construction sites, temporary offices and emergency resettlement. At the same time, the combination of multiple modules can also form a larger space.
- Stable Quality: The factory adopts standardized production lines and strict quality inspection procedures, avoiding the impact of on-site weather, labor and other factors on the construction quality. The product quality is more stable and reliable.
- Strong Adaptability: It can adapt to various geographical environments and climate conditions, whether it is a cold area or a hot and humid area, it can be adjusted through material selection and structural design to ensure the comfort of use.
- Energy Saving and Environmental Protection: The production process adopts precise material allocation, which reduces material waste. At the same time, the house has good thermal insulation and sound insulation performance, which can reduce energy consumption during use.
Is the Cost of Modular Houses Cheaper?
Many customers are concerned about whether modular houses are more cost-effective than traditional buildings. The answer is yes, and the cost advantage is obvious. According to a comparative analysis of construction costs, modular construction can reduce the total project cost by up to 20%, and 91% of construction managers have observed cost reductions in modular projects, with 53% seeing a reduction of more than 10%.
The cost advantage of Dongji modular houses mainly comes from three aspects: First, the factory's large-scale and standardized production reduces the waste of materials and labor costs; second, the short construction period saves the management cost and time cost during the construction period; third, the detachable and reusable characteristics reduce the cost of secondary construction. In addition, our cost is more transparent, without hidden charges, and customers can obtain high-quality products at a more favorable price.
Do Modular Houses Have an Impact on the Environment?
In contrast to traditional construction methods that generate a lot of waste, modular houses are a more environmentally friendly choice and have little negative impact on the environment. According to the U.S. Environmental Protection Agency (EPA), construction and demolition waste accounts for about 40% of all waste in the United States, while modular houses can effectively solve this problem.
On the one hand, the factory's precise production can minimize material waste— the waste rate of concrete and steel in modular house production is only 1%-2%, while that of traditional cast-in-situ buildings is 2%-5% for steel and 3%-5% for concrete. On the other hand, the on-site assembly process of modular houses does not require a lot of earthwork, which avoids damage to the surrounding vegetation and soil. In addition, the materials we use are all environmentally friendly and recyclable, which can be reused after disassembly, further reducing environmental pollution and resource waste. It is a green and sustainable construction method advocated by the global construction industry.
