[expert perspective] National precast building development report series in 2021 (XIII)
Humanized design: barrier free connection is adopted.
The assembly decoration is adopted, the kitchen and bathroom, the entrance and the storage are finely designed, and a large number of healthy building materials are used to make the living experience more friendly and beneficial to health.
2.
It realizes the data transmission, interaction and summary of construction information in the whole life cycle of buildings, and creates the world’s first Internet-based construction process big data integration system.
Construction robot, intelligent production: CSCEC science and technology independently developed a rebar binding robot with machine vision to carry out standardized and modular binding production of rebar.
Sustainable concept: the space layout in the suite is standardized by “limited modules”, which is convenient for industrial construction and project management; Realize “sustainable use” of the whole life cycle of the building by “unlimited growth”.
In particular, the organic combination of color application to external wall bay windows and green plants in the building facade design highlights the “beauty of quality, lean beauty and vertical greening environment”.
Intelligent construction takes the intelligent construction platform independently developed by CSCEC technology as the control center, covering design, calculation and pricing, bidding and procurement, production, construction and operation and maintenance.
(3) Green, smart and healthy – Shenzhen digital integrated intelligent construction sustainable residential district is the largest precast building community in China that practices the new development concept and integrates green, smart, science and technology and humanity.
“Three complete BIM”, digital design: 1.
Adopt the working mode of “cloud desktop” to realize the point-to-point full professional collaboration mode.
3.
Standardized design: it innovates the design method of “four standardization”.
Based on high quality, we will change the old impression that affordable housing is “low-end housing”.
The wisdom of eight academicians of the Chinese Academy of engineering is gathered in the whole process from design to construction, and a variety of advanced green construction technologies are adopted to build a national and even world-class public housing benchmark.
Eight benchmarks: high-quality public housing benchmark, green construction benchmark, full life cycle BIM application benchmark, humanistic community benchmark, smart community benchmark, scientific and technological residential area benchmark, high-quality residential area benchmark, and standardized application benchmark in urban construction.
Build high-quality public housing with ingenuity and create three national models and eight industry benchmarks.
Upload the digital twin buildings generated by offline design to the Internet cloud platform through the self-developed lightweight engine to support the informatization management of business, manufacturing, construction and operation and maintenance.
The green platform on the second floor is an exclusive park like landscape environment.
Starting from plane standardization, it realizes the diversity of plane layout, module combination, facade composition and planning layout.
UAV automatic patrol inspection and robot 3D modeling: UAV cloud preset route, automatic patrol inspection on the site, automatic vectorization model of the construction site through graphic algorithm, and construction of time and space dimension construction site big data system.
Machine vision recognition of unsafe behaviors: AI vision recognition combines self-learning technology and machine vision technology to capture the actions and wearing images of on-site personnel, carry out real-time identification, real-time alarm and on-site punishment of on-site personnel’s unsafe behaviors, and finally record the whole process on the cloud, so as to further standardize the safety behaviors of on-site personnel and reduce the potential safety hazards.
Target the advanced manufacturing industry, improve the quality of precast components, save labor costs, and achieve lean construction..
Full life cycle component traceability: the BIM model lightweight engine generates a unique identity code for each precast component, and uses two-dimensional code technology to record component production, construction and other information in the whole process, so as to realize the traceability of component life cycle information, and the interconnection of all elements and data in the construction process.
Based on BIM design, through BIM model aided calculation, virtual construction, full professional BIM model display and panoramic VR technology, the design change and process management of all staff and all disciplines are realized.
The total investment of the project is 5.8 billion yuan, and the total construction area is about 1.16 million square meters.
Three major demonstrations: the demonstration community of the national sustainable development agenda Innovation Demonstration Zone, the comprehensive demonstration project of the key projects of green building and building industrialization under the national 13th five year plan, and the national precast building science and technology demonstration project.
At the same time, the point cloud 3D mapping robot can independently plan the work path and complete the obstacle avoidance according to the designed BIM model, complete the millimeter level point cloud mapping scanning on the project site, return the data through the 5g network, automatically establish the building point cloud model on the cloud, and integrate with the UAV model, so as to realize the automatic comparison with the BIM design data and automatically generate the quality report.
Renderings of Shenzhen Changzhen public housing and its ancillary projects Changzhen project is the largest precast public housing project under construction in China, the largest precast decoration and precast landscape community in China, and also a pilot project for the reform and innovation of Shenzhen construction management mode.
Green and livable: Based on the original relationship between human and nature, the planning and design strategy of “green ecology and healthy life” is comprehensively implemented from the aspects of construction, operation and maintenance as well as living use, with the original intention of “health, efficiency and humanity” and serving people’s happy life.
The Shenzhen project comprehensively applies green, intelligent and scientific precast building technology to create a new benchmark for urban construction in the new era of construction to practice the new concept of development.
Garden style community: the assembled landscape technology product system independently developed by CSCEC science and technology is fully applied to reduce the interference and damage to the “green water and green mountains” and realize the integration and coordination of the artificial environment and the natural environment.
