45%

Green and Low Carbon

Innovative practices with a 45% carbon reduction rate

 

 

The project promotes and applies 8 of the 10 new technologies in the construction industry, with 28 sub-items, optimizing the enclosure structure and energy system to achieve an overall carbon reduction rate of 45%.

Green building materials and green technology demonstration
 

 

The project is designed with the goal of achieving a national three-star green building (preliminary score 88.6 points), and uses the Fifth Bureau's independently developed "China Construction E-Stone," "China Construction Xihaosi" and other green building materials.

 

Applied photovoltaic curtain walls (estimated annual power generation 300,000 kWh), sponge city construction technology (permeable pavement rate of 50%+ application of self-developed permeable bricks ), optimizing the building wind environment, achieving 50% rooftop greening. Relying on the Fifth Bureau's full industrial chain advantages, it achieves green and low-carbon operation throughout its life cycle, from building material production and construction to later maintenance.

52%

Prefabricated Construction

Technological breakthrough with 52% prefabrication rate

 

The project applies four prefabricated systems (main structure, pipeline system, interior decoration, and municipal landscaping), with an overall prefabrication rate of 52%. The floor uses a non-筋开槽型叠合板 (a type of composite floor slab), which can effectively prevent cracking.

 

The stairs use the Bureau's Engineering Innovation Research Institute independently developed UHPC stairs, reducing self-weight by 50% and increasing load-bearing capacity by 200%.

 

First-ever "misaligned mutual anchoring" non-sleeve connection technology (5d anchoring reaches HRB400 strength), which can achieve strong anchoring, short lap joints, high fault tolerance, and no binding, facilitating maintenance and inspection, and having high durability and waterproofness.

Interior decoration uses removable partition walls and honeycomb aluminum panel ceilings (disassembly and installation efficiency increased by 3 times), which can reduce 90% of construction waste. Municipal landscaping projects use fully recycled materials, fully implementing efficient and low-carbon construction.

50+

Intelligent Construction

More than 50 technologies drive full-process upgrades

 

The project uses a BIM collaborative platform and an intelligent review system to achieve high-efficiency integrated design of electromechanical and decoration. Relying on intelligent production lines and intelligent logistics systems, it ensures precise delivery of prefabricated components. The construction site uses an independently developed management platform combined with construction robots and unmanned tower crane systems, improving construction efficiency by 5.6%, saving labor by 500 working days.

Construction robots and unmanned tower crane systems

 

Innovative application "Smart Standard Curing System," remote monitoring of the entire process from test block production to testing implementation. Based on the Internet of Things platform, it monitors water and electricity consumption and the operation status of unmanned tower cranes in real time, and uses an intelligent early warning system to build a comprehensive safety management system.

 

"Smart Standard Curing System

 

During the operation and maintenance phase, it creates the Fifth Bureau's national data operation center , building a "point-surface-body" three-level smart development pattern; using smart buildings as a demonstration core to create a smart urban ecological circle. Implementing a "planning-construction-operation" full life cycle intelligent construction management system. Providing the industry with replicable and promotable digital solutions.
