1. Persistent Shortcomings of Traditional Construction Site Worker Dormitories

Traditional temporary worker dormitories have failed to meet modern green construction and humanized management standards due to outdated design concepts and backward building technologies. Most construction enterprises prioritize low upfront costs and rapid construction progress when building temporary accommodation, ignoring long-term environmental impact, worker living quality, and resource utilization efficiency. These inherent flaws make conventional dormitories unsuitable for the sustainable development needs of the modern construction industry.

First of all, traditional dormitories face severe environmental and health risks. Low-cost ordinary color steel cabins use inferior adhesive and foam core materials containing formaldehyde, benzene, and other volatile harmful substances. These toxins continuously volatilize indoors throughout the building’s service cycle, polluting indoor air and triggering respiratory diseases, skin allergies, and other health problems among long-term resident workers. Wooden temporary huts consume massive natural wood resources and are prone to decay, mildew, and bacterial breeding in humid environments. Furthermore, most traditional temporary buildings adopt fixed welding structures that cannot be disassembled and reused. After project completion, obsolete dormitories are directly demolished, generating large quantities of non-degradable construction waste that occupies land resources and aggravates ecological pollution.

Secondly, traditional dormitories provide poor living comfort and low environmental adaptability. Ordinary single-layer color steel panels have extremely limited thermal insulation and sound insulation performance. In hot summer seasons, indoor temperatures rise sharply, while indoor heat dissipates rapidly in cold winter, resulting in extreme indoor temperature fluctuations. Additionally, simple splicing structures cannot block external construction noise, wind noise, and dust, leading to noisy and dusty living environments. In rainy, humid, coastal salt spray, and desert sandstorm environments, traditional dormitories are prone to water leakage, wall peeling, rust deformation, and mold growth, creating damp, messy, and unhygienic living conditions that severely affect worker rest quality and physical health.

Thirdly, traditional temporary buildings have low structural durability and high full-life-cycle costs. The thin and fragile structural design of conventional dormitories results in poor wind resistance, seismic resistance, and impact resistance. Most ordinary temporary dormitories only have a service life of five to eight years and require frequent maintenance, component replacement, and renovation during operation, consuming substantial manpower and material resources. Moreover, the disposable construction mode forces enterprises to repeatedly invest in building new dormitories for different projects, leading to continuous redundant capital expenditure and low overall project economic benefits.
