Lida Construction Tackles Massive Retrofit Project

Prefab housing leader Lida Group has signed a major contract to convert over 1,000 outdated warehouse facilities across Eastern China into modern labor dormitories using their innovative structural insulated sandwich panel system. The ambitious multi-year retrofit project aims to provide improved accommodation for migrant workers while demonstrating modular building methods’ potential to upgrade aging building stock sustainably on a vast scale.

Dated warehouse structures built in the 1990s are common in industrial zones but often lack amenities and insulation. Workers frequently reside in crowded, unsanitary conditions. Lida’s structural sandwich panels offer a cost-effective solution. Comprising rigid foam cores fully encased between rigid steel facings, the lightweight panels bolt rapidly onto existing structural frames to form durable, airtight enclosures without full demolition.

Prefab Modernization

Lida’s scope encompasses dismantling non-loadbearing internal walls while refurbishing flooring, adding kitchens and bathrooms. The company’s proprietary Prefab Modernization Management System uses BIM modeling and lean construction techniques. Standardized panel cassettes for floors, walls and roofs are factory fitted with MEP systems, finishes and joinery prior to flat packing for efficient on-site assembly.

Project Director Chen Huan notes Lida aims completing full retrofits within 3-6 months per building through strictly planned work sequencing. Compared to traditional methods taking 1-2 years, this minimizes occupancy disruption. By improving 10,000-15,000 housing units annually over 10 years, Lida addresses urgent accommodation shortfalls sustainably.

Sustainable Performance Upgrades

Critical to Lida’s model is maximizing buildings’ functional lifespans while minimizing environmental impacts. Sandwich panels boost airtightness 300% cutting energy use 30-50%. Their rigid cores provide four times the insulation of masonry, enhancing comfort year-round. Lightweight steel framing strengthens wobbly structures seismically.

Upon completion, dormitories will earn top-level green certifications. Their operational cost savings from efficiencies exceed typical newbuilds within 5 years. Most notably, sustainable retrofits displace over 25 million tons CO2e GHG emissions – equivalent to removing 5 million cars annually according to life cycle analyses.

Integrated Community Revitalization

Lida aims partnering with other firms during massive retrofits to holistically boost surrounding areas. They assist modernizing commercial and community spaces with advanced prefab techniques creating vibrant live-work-learn zones.

Renewed infrastructure like district energy, WiFi and recreational amenities enhance quality of life while fostering pride of place. Local job training programs recirculate over $2B in salaries annually from construction alone. If replication licenses this model nationally, millions could benefit from revitalized districts powering circular blue-collar economies.

Summary

In summary, Lida Group’s landmark agreement to retrofit over 1,000 aging industrial park warehouses expedites delivery of sustainable, modernized labor housing through innovative modular methods. Beyond shelters, the comprehensive undertaking promises to regenerate entire districts via prefabricated efficiencies uplifting communities and environments socioeconomically for generations to come. If successful, the project sets a global precedent for mass property retrocommissioning as a climate solution.
