Vanke Jade New Metropolis Commercial Project: Steel Structure Prefabrication Leads Efficient Construction—Prefabrication Rate Exceeds 90%, and Main Structure Completed in Just 45 Days

The Vanke Jade New Metropolis Commercial Project, with its innovative construction solution of steel structure assembly system and 100% dry construction, achieved an assembly rate of over 90%, main construction in only 45 days, and a 60% reduction in construction period compared to traditional concrete structures. It has become a benchmark practice for industrialized, green, and efficient construction in the commercial building field. The project focuses on steel framed lightweight floor panels, insulated roof panels, insulated exterior wall panels, and insulated daughter wall panels as the core components. The total area of prefabricated panels is 12000 square meters, fully demonstrating the technical advantages and application value of steel structure prefabricated in commercial projects.

1、 Core construction system of the project: fully assembled+fully dry process, creating an efficient construction mode

1. Main structure: Steel frame structure, stable and efficient

The main body of the project adopts a steel structure frame system, and load-bearing components such as steel columns and beams are standardized and prefabricated in the factory. They are precisely connected on site through high-strength bolts, without on-site welding or wet pouring operations. Steel structures have light weight, high strength, excellent seismic performance, and a component recycling rate of over 90%, which is in line with the concept of green and low-carbon construction and lays a solid foundation for the rapid construction of commercial projects.

2. Core components: Four major prefabricated boards, full process assembly

The project enclosure and floor system adopts four prefabricated components with a total area of 12000 square meters, achieving the full process industrial construction of "factory prefabrication and on-site assembly":

Steel framed lightweight floor panels: factory integrated molding, with light weight, high strength, and excellent flatness. They can be directly hoisted and spliced on site without the need for formwork or concrete pouring, greatly reducing on-site processes.

Integrated insulation roof panel/exterior wall panel/daughter wall panel: integrating insulation, waterproofing, load-bearing, and decorative functions, prefabricated in the factory and hoisted as a whole, replacing traditional roof/exterior wall cast-in-place, insulation layer paving, waterproof construction and other multiple processes, improving construction efficiency and quality.

3. Construction technology: 100% dry operation, breaking through traditional limitations

The entire project adopts 100% dry construction technology, completely eliminating wet work processes such as concrete pouring, mortar plastering, and on-site maintenance. All processes are dry assembly. The construction process is "factory prefabricated components → transportation to the site → hoisting and positioning → bolt fastening → finished product protection", without maintenance waiting period, sewage discharge, and construction waste accumulation, eliminating dependence on water sources, temperature, and humidity, adapting to various climatic conditions, and achieving uninterrupted construction throughout the year.

4. Assembly rate: over 90%, new height of commercial building assembly

According to the standard for calculating the assembly rate of prefabricated buildings, the project achieves an assembly rate of over 90% through 100% prefabrication of the main steel structure, 100% assembly of the enclosure/floor system, and synchronous assembly of the interior and mechanical and electrical systems. This far exceeds the conventional assembly level of commercial buildings and has become a model for the deep application of prefabricated steel structures in the commercial field.

2、 Core advantages of steel structure prefabricated commercial projects: comprehensive leading in efficiency, cost, quality, and green

1. The construction period has been significantly shortened, seizing the commercial opportunity

Compared to the traditional concrete structure commercial project with a main construction period of over 110 days, the main construction of this project is only 45 days, which shortens the construction period by 60%. Dry construction has no waiting time for maintenance, and components can be installed as needed, achieving "rapid topping out, rapid decoration, and rapid opening", helping the project seize the commercial operation window period in advance and enhance market competitiveness.

2. Significant cost optimization, reducing costs and increasing efficiency

Reduce expenses for measures such as templates, scaffolding, and maintenance by approximately 40% compared to traditional construction methods;

Reduce on-site workload by 70%, significantly reduce labor costs, and alleviate labor shortages;

Reduce construction waste by over 80%, lower the costs of transportation and environmental protection, and meet the requirements of green building development.

3. Excellent quality and performance, suitable for commercial needs

Insulation has the same lifespan as the building: The integrated insulation components adopt integrated technology to avoid the problems of traditional insulation layer detachment and aging. The insulation performance has the same lifespan as the main building, greatly reducing maintenance costs in the later stage;

Flexible Space Adaptation: Steel structures with large spans and few beams and columns provide spacious and flexible indoor spaces for commercial projects, meeting the diverse layout needs of shops, offices, leisure and other businesses;

Quality controllable: Factory standardized production, component accuracy controlled at millimeter level, small on-site assembly errors, avoiding common quality problems such as hollowing and cracking caused by traditional cast-in-place.

4. Green and low-carbon, implementing the dual carbon goals

No wet operation wastewater, no on-site dust, environmentally friendly and pollution-free construction process;

Steel structures can be 100% recycled, and prefabricated components reduce raw material waste. Each square meter can reduce energy consumption by 12%, water consumption by 39%, and carbon dioxide emissions by 15%, helping the construction industry to transform towards green and low-carbon.

3、 Project Value and Industry Significance

1. Industrial demonstration of commercial buildings

The Vanke Jade New Metropolis Commercial Project, with a 90%+assembly rate, a 45 day main construction period, and 100% dry construction practice, has verified the feasibility and superiority of the steel structure prefabricated system in the field of commercial buildings, providing replicable and promotable efficient construction solutions for short cycle and high turnover commercial projects such as commercial complexes, commercial streets, and sales offices.

2. Technological innovation leads industry upgrading near

The project promotes the deep extension of steel structure prefabricated technology from the residential field to the commercial building field, breaking through the pain points of low construction efficiency, long cycle, and high pollution in traditional commercial buildings, and leading the construction industry to transform and upgrade towards "industrialization, greening, and intelligence".

3. Highlighting brand and market value

The rapid implementation of commercial projects helps Vanke Jade New City make an early debut, enhancing Vanke's brand influence in the regional market; At the same time, green construction technology is in line with urban development planning, winning market recognition and policy support for the project, and helping it become a regional commercial benchmark.

4、 Summary

The commercial project of Vanke Jade New Metropolis is centered around steel structure, four major prefabricated panels, 100% dry construction, and a 90%+assembly rate, achieving comprehensive surpassing of traditional concrete structures in terms of construction period, cost, quality, and green environmental protection. The project is not only Vanke Group's innovative practice of prefabricated technology in the field of commercial construction, but also provides an efficient, reliable, and scalable construction model for the industrialization of commercial construction nationwide, helping the industry achieve the high-quality development goals of "efficiency improvement, cost reduction, green, and high quality".
