Shortage of Prefab House Installers in the US

Installers of prefabricated houses in the US face a severe shortage, and installation efficiency and costs are significantly affected by labor factors.

Current Situation of Labor Shortage

The US construction industry as a whole is experiencing a long-term and severe labor gap. The monthly shortage of construction workers across the country reaches as high as 250,000, with the peak even exceeding 400,000 during prosperous years. This phenomenon is equally prominent in the field of prefabricated house installation, mainly due to two reasons:

• Aging population and declining industry attractiveness: Skilled workers such as bricklayers and carpenters from the older generation are retiring one after another, while young people are reluctant to enter the construction industry due to high work intensity and low professional recognition.
• Tightening immigration policies: The construction industry has a high dependence on immigrant labor. However, in recent years, the tightening of immigration policies has led to insufficient replenishment of foreign workers, further exacerbating the labor shortage.

Comparison of Installation Efficiency and Costs

The labor shortage has directly impacted the installation efficiency and costs of prefabricated houses in the US:

• Efficiency differences: Chinese prefabricated houses, through modular design, transfer most of the processes to the factory for completion, with low dependence on on-site installation. For example, an American couple, with the assistance of their father, can complete the installation of a house within one day using a telescopic forklift. In contrast, it takes 6 to 18 months to build a house of the same size using traditional methods in the US, resulting in a long construction period.
• Cost differences: In traditional US construction methods, labor is one of the largest and most costly inputs. The scarcity of skilled workers has led to high labor costs. For example, the labor cost for building a house is approximately $200,000. In contrast, Chinese prefabricated houses reduce on-site labor requirements through factory production, offering significant cost advantages.

Long-term Impacts on the Industry and Market

The labor shortage has had a profound impact on the US construction industry:

• Extended construction periods and difficulty in scheduling workers: Construction companies need to schedule workers 4 to 5 months in advance. Skilled workers are becoming increasingly difficult to find, leading to project delays becoming the norm.
• Increased costs and housing prices: Rising labor costs have directly pushed up the total construction costs, which in turn have been passed on to housing prices, exacerbating the supply-demand imbalance in the housing market.

In conclusion, the field of prefabricated house installation in the US faces challenges of low efficiency and high costs due to labor shortages. China, through modular design and factory production, provides a reference path for addressing this issue.
