From Oct. 31 to Nov. 2, STEC attended 2017 Shanghai International Fair of Architecture and Urbanism, showing governments, employers and citizens how intelligent infrastructure will affect every aspect of city life and presenting audiences with a picture of the smartest and coolest city of tomorrow.
Detailed reports were given by major media, including Xinhua News Agency, Shanghai TV Station, Dragon TV, Shanghai People’s Broadcasting Station, Shanghai Traffic Radio Station, Liberation Daily, Xinmin Evening News, Shanghai Morning Post, Labor Daily and Youth Daily
During the fair, the leaders who visited STEC’s pavilion were Xue Chao, vice director of the Standing Committee of Shanghai Municipal People’s Congress, Cui Minghua, secretary of the CPC Party Committee of Shanghai Municipal Construction and Traffic Committee, Hong Yongping, director of the Commission of Housing and Urban-Rural Development of Shanghai Municipality, vice director Pei Xiao and chief engineer Liu Qianwei from the same agency, Zhang Yan, secretary of the CPC Party Committee of STEC and chairman of the board, president and vice secretary Zhou Wenbo and the company’s leading team members, as well as related leaders of Urban Planning Society of China, Architectural Society of China, Urban Construction and Environmental Protection Committee of Shanghai Municipal People’s Congress, Committee of Population, Resources, Environment and Construction of CPPCC of Shanghai Municipality, and Shanghai Green Building Association.
GIS+BIM basic platform, developed by STEC Shanghai Underground Space Architectural Design & Research Institute, is different from ordinary maps—it is three-dimensional and, like “Amap” of urban infrastructure, collects the BIM models of major infrastructure of a city. Direct, real and accurate decision analysis and suggestions can be provided for urban construction and management authorities, because on the platform are available the 3D BIM models and geological position information of all projects, from the road restoration near residents’ homes to 10-billion-yuan “No. 1” project North Cross Passage, completed projects or projects underway.
Smart operation and management platform: capable of operation, management and maintenance of a city’s transport infrastructure
The BIM+GIS-based smart operation and management platform collects the information on operation, management and maintenance of Shanghai’s transportation facilities responsible by Shanghai Urban Construction Urban Operations Group, including road closure, road maintenance, personnel on duty and whether infrastructure works well. As long as a manager opens the smart operation and management platform each day, he will get access to the information on urban operation and management, and organize and distribute resources to do maintenance.
CJ-TIMS platform: “AlphaGo” that serves a city
CJ-TIMS Platform is “AlphaGo” in urban infrastructure construction and operation. The platform, developed by STEC Shanghai Urban Construction Design & Research Institute, may collect real-time data through sensing devices that are installed in every corner of a city, and make “smart decisions”. Through the smart operation and management platform, operators and managers may soon learn of and find the reason of road water-logging. After related data are collected by it, CJ-TIMS platform may prejudge “the next day’s rate of road water-logging” through gathered weather information plus historic data, and thus offering the most reliable assistance basis to help urban managers with decisions.
One Touch BIM model: drone + BIM= new direction of urban construction
At this fair, STEC Shanghai Road and Bridge (Group) Co., Ltd. and STEC Shanghai Urban Construction Design & Research Institute showed drone + BIM, a new direction of urban construction. A 3D model of the ground around a road project may be formed through One Touch by using thousands of photos taken by a drone that has a number of cameras capable of recording satellite navigation coordinates. Then the BIM model is put into a virtual “actual” environment where the project is closely integrated with its surroundings, to improve the quality of project design and construction.
Currently, the technology has been applied to Shanghai Kunyang Road Bridge, Chongming Ecological Avenue and Beiyan Passage. After surveying and mapping 70 kilometers of municipal road, the accuracy of the 3D real model made by STEC has reached 2 millimeters, the highest in China, and the rate at which the work is done is 400 times faster than surveying and model building with humans. As a result, the time spent in construction is shortened, and the influence of a project to ecology and its consumption of resources have been minimized.
Smart facilities: manhole covers and viaducts “can speak and give alarms”
Road water-logging, missed manhole covers, super-high vehicles running on viaducts and other “troubles” happening on the roads of a city will make travel difficult. How to detect them as soon as possible? At this fair, “Smart Manhole Covers” and “Lane Super-elevation Laser Video Apparatus”, narrow-band-based Internet of Things technologies of Shanghai Urban Construction Urban Operations Group, caught great attention of citizens. The two devices are of size less than a palm. One of them could detect abnormal road water-logging and give risk alarms at the first time; the other could monitor super-high vehicles and inform road maintenance and traffic police departments in time to take action. They are “speakers” of the road, and in case of abnormal situations and hidden risks, they may detect them and send alarms, so that the most accurate information may reach the smart operation and management platform as soon as possible to ensure citizens’ safe travel.
Thinking factories: prefabricated bridge production bases capable of thinking and technical expertise
What is a thinking factory like? STEC Shanghai Urban Construction Municipal Engineering (Group) Co., Ltd. showed the audience “the smartest” production base of preformed units in Shanghai. With the unique advantages of BIM technology and the digital management and control platform, the group may make a visual browse of the progress of preformed units and visual monitoring of the whole process of production, especially for prefabricated units that require high precision, by smart measurement and calculation as well as BIM model, precision error may be limited to less than 2 millimeters. In addition, a few functions like smart design assistance platform, coordinative production management platform and manufacturing execution system have been realized.
Shield management and control center controls shields a thousand li away
In Shanghai, the city with the longest rail traffic mileage in China, there are a hundred subway shields running underground in rush hour. STEC Shanghai Tunnel Engineering Co., Ltd., whose total subway construction mileage has exceeded 790 kilometers, has given full play of its technical advantages and management experiences in constructing tunnels with shields, and built a multiple functioned and modeled management and control system that combines project construction management and shield equipment management. This system not only accomplishes remote management of construction, but also enables technicians who stay at their offices in Shanghai to monitor and manage the shield projects in Zhengzhou, Zhuhai, and even in Singapore, to enable them to make dynamic analysis, to give risk alarms, to provide timely smart decisions, so as to accomplish life-cycle management of shield equipment.
Smart green construction: Internet + industrialized production
iGreen of STEC Shanghai City Building Material Co., Ltd., driven by technological innovation, utilizes its over twenty years of experiences in prefabricated units manufacturing and industrial management to integrate industrial chains, based on “Internet + industrialized production”. It spares no effort to build zhaopc—an industrialized iGreen service platform for assembled building industry, to really establish a standard industrialized system of PC industry which involves design, production, installation and decoration.
