How the "Luban Award" was created

From August 18 to 19, 2015, as the first stop for Beijing to participate in the Luban Award project, the renovation and expansion project of Beijing Gloria Hotel underwent a two-day careful inspection by the Luban Award expert group and critique. This hotel project with a construction area of ??62,805 square meters won unanimous praise from the expert group. On November 17, 2015, it lived up to expectations and once again won the golden Luban statue for China Xinxing Construction and Development Corporation.

Fashion and tolerance coexist

The renovation and expansion project of Beijing Gloria Hotel is jointly developed and managed by COFCO and the American Starwood Hotel Management Group. The project is located on Jianguomen South Street , echoing the solemn Forbidden City and the world-famous Tiananmen Square, across the street from the ancient observatory witnessing the changes of time and changes over the years. At the same time, it is adjacent to the vibrant Xiushui Street and the bustling diplomatic and business district. Looking out the window, you can have a panoramic view of the Beijing skyline, with skyscrapers, imperial palaces and ancient temples complementing each other. The location of the project itself has the characteristics of vicissitudes and modernity, simplicity and fashion, which are reflected in the engineering design. This collision and tolerance of time, space and texture are everywhere.

In the morning, dusk and dawn, the project refracts the rays of the sun, reflects the leisurely clouds, and exudes a metallic texture. It is simple and elegant; when the neon lights first come on, the project is brightly lit, shining and brilliant. Like a star, it is fashionable and avant-garde; when you are there, the design guidance of "Five Stars Dazzle" highlights the vitality of WHotel, a young brand, and many design details of blue and white porcelain, Chinese red, painted tiles, and round sky and square sky are also Cleverly incorporating Chinese elements, it is eclectic, fashionable and elegant.

Innovation and technology go hand in hand

Zhang Lei, deputy general manager of the first company of China Emerging Construction and Development Corporation, said that in order to better reflect the design concept and realize the quality of the process, the Gloria Hotel Project Department During the project construction process, we always adhered to scientific and technological innovation, fully carried out QC group activities, pursued the depth and breadth of science and technology, created outstanding results, and gained valuable experience.

During the structural construction, the technical staff of the project department discovered that the concrete was poured using a placing machine. When one component was poured and transferred to the next, the concrete in the placing tube would cause damage due to its own weight and pressure. A large amount of waste is not only wasteful, but also requires a lot of manual work to clean up, which greatly increases the construction cost. It can be said that this problem is a common problem in construction construction, but few people pay attention to the improvement measures. The project department decided to carry out technical research and organized technicians to practice together repeatedly, and finally invented a concrete distribution pipe sealing pipe head. This pipe head is easy to process, low cost and easy to use. It effectively solves the problem of concrete leakage and creates a With good economic benefits, this innovation successfully obtained a national invention patent.

During the electromechanical installation stage, the technical staff of the project department designed and produced a new type of fan coil return air box filter connector, which improved the problems of traditional connectors such as more materials, complex processing, and high production costs. . The new product fully meets the installation needs of the filter on the return air box, and is firmly connected, easy to install, flexible to disassemble, and low in cost. It can be processed in large quantities on site using only a small amount of materials or scraps. This innovation has won the national utility model patent. .

It is reported that the project also innovatively applied BIM technology to comprehensively arrange pipelines and machine rooms, conduct construction simulations of tube wells, and pre-arrange roof tiles, etc., which reduced the error rate and ensured the construction effect. 3D printing technology was used to create a prototype model of the special-shaped arc ceiling of the mysterious space on the first floor, allowing the owners and related parties to more intuitively refer to the spatial effect, and carry out lofting, processing and installation according to the model, which improved construction efficiency and accuracy. The indoor and outdoor decoration of the project uses a large number of assembled decorative materials, factory production and processing, and on-site assembly construction, which not only saves costs, but also speeds up the construction. This method represents the development trend of modern decoration and ensures the maximum Green construction, energy conservation and emission reduction.

According to statistics, this project has applied 10 major and 25 sub-items of the 10 new technologies in the construction industry, including 3 independent innovative technologies and 5 innovative application technologies, and has formed a provincial and ministerial level construction method. 1 item and 2 national patents. The formation and application of these innovative achievements have become a highlight in project construction and have been fully recognized by experts.

Wisdom and sweat only exist

The renovation and expansion project of Beijing Gloria Hotel is a key project of China Xinxing Construction and Development Corporation, and the Gloria Hotel Project Department undertaking the project is a subsidiary of The brand project department of Xinxing Construction Company. The "COFCO Fulinmen Building Project" they built for COFCO Group won the "Luban Award" in 2010. This time they cooperated with COFCO Group again, and both parties unanimously targeted the "Luban Award" .

Bao Jicheng, project manager of the renovation and expansion project of Beijing Gloria Hotel, said that due to the special geographical location of the project, the construction will inevitably face three major problems. One is the civilized safety of construction dust, road debris, noise, etc. The construction requirements are of high standard; secondly, there is traffic congestion and frequent traffic control, making it extremely difficult to transport materials; thirdly, the on-site fence is only 4 meters away from the residential buildings and only 6 meters away from the National People's Congress office building, which causes a serious problem of disturbing residents. In response to these problems, the project department has done a lot of work. In order to create a clean and orderly on-site environment, non-stop waste cleaning and watering and dust removal are implemented on-site; a sedimentation tank is set up on-site for sewage and wastewater treatment; a fully enclosed mobile garbage bin is set up, and garbage and slag are stored and transported in the Municipal Environmental Sanitation Bureau’s transport boxes. Special personnel are assigned to sort and clean up; vehicles carrying construction materials, garbage and slag are covered to prevent dust. The project was rated as a civilized and safe model construction site in Beijing. Regarding the problem of nuisance and nuisance to residents, the project department took the initiative to set up a 6-meter-high soundproof and dust-proof fence on the side of the National People’s Congress office building in the south. The candid, sincere and thoughtful service won the trust and understanding of the surrounding residents.

During the foundation pit soil protection construction stage, the project department successfully overcame the construction difficulties. Since the project is located along Chang'an Street of the East Second Ring Road, and the west side of the foundation pit is only 5 meters away from the Second Ring Road, the excavation depth of the foundation pit is -27 meters, with the deepest reaching -30 meters. The construction is very difficult, and its depth is Beijing It was the largest foundation pit constructed in the city that year. Moreover, the underground conditions around the foundation pit are very complex, with power cables, heat, natural gas and other pipe trenches densely distributed. In order to ensure the safety of the foundation pit and surrounding buildings and roads, the project department and the design department repeatedly optimized the support plan, and finally determined a construction plan in which the foundation pit uses seven different support sections and the foundation pit anchors are set in sections. The foundation pit is optimized for comprehensive support with water-stop curtains and closed dewatering, which ensures the safety and stability of the foundation pit under high water level conditions and minimizes the impact of construction on the surrounding environment.

For the smooth progress of the project construction, all the staff of the project department have devoted too much wisdom and sweat. They adhere to the "three special qualities" of a company that are "especially able to endure hardship, especially able to fight, and especially able to endure". "Spirit", the project manager dragged his injured leg to stick to his post and led all staff to fight on the front line. The veteran comrades in the project department did their part in all tasks and set a good example. Some young people in the project department were still conducting municipal construction law review reports the day before the wedding; some whose fathers were sick and admitted to the hospital had to entrust their wives to take care of them. Too much dedication, too many stories, too much sweat and tears, in exchange for the complete success of the project construction, finally realized the dream of Luban.

Wang Yinghua, Secretary of the Party Committee of the First Company of China Xinxing Construction and Development Corporation, told reporters that as an ace team of the Corporation, the First Company has continuously built "brand building projects" over the years and firmly established the "official kiln quality building" and "Ministry and Commission Engineering Professionals" brand image, and always regards quality as the cornerstone of brand building. It has won 8 Luban Awards, 1 Zhan Tianyou Civil Engineering Award, 3 National Excellent Projects, 19 National Patents, and the National Construction Industry Award There are 2 new technology application demonstration projects, 7 new technology application demonstration projects in the Beijing construction industry, 6 national green construction demonstration projects in the construction industry, and 8 national AAA safety and civilized standardized construction sites, achieving simultaneous improvement in social and economic benefits. .
