On 27th March,OPEN Project Exchange and Observation Meeting was successfully held in Foshan, Guangdong Province, with more than two hundred representatives from 29 owner units, 54 design units and management companies from all over the country coming to the site.

The project is EPC general contracted by OPEN EPC, built with armour frame structure, with a total floor area of 118,601 sqm and a total height of 67.5 metres, lorries can be driven directly to the 6th floor through the tray way, which is one of the highest warehouses in China.

Welcome Address

Chen Ming, Chairman of OPEN, made the opening speech of the conference, he said: since the first project of the CS-Frame System to today, the application project has reached 3.5 million square metres, and has been unanimously recognised by customers, which is very gratifying. We also hope that we can cooperate with more customers, design units and industry colleagues in the future for mutual benefit and progress.

The representative of the owner's unit shared from the perspective of the A-side: this project, as the tallest multi-storey warehouse in Guangzhou and Foshan, is positioned as an intelligent logistics hub in Guangdong, Hong Kong and Macao Greater Bay Area. At the early stage of design, the team compared traditional solutions such as cast-in-place frame structure and heavy steel frame, and found that there were problems such as long construction period and high cost, while the armour frame system was free of formwork construction, lighter beam and column members than traditional steel structure, and had a high lifting efficiency on average per day. At the same time, in view of the successful cooperation experience with OPEN team in three projects in East China, the final choice of shell structure scheme.

The current construction schedule nodes meet the requirements, thanks to the technical synergy of the shareholders, designers, management company, OPEN team and the efforts of the construction team. Practical data shows that the system can shorten the construction period by more than 10 per cent compared with traditional cast-in-place structures.

Mr Qiu, the representative of the globally renowned engineering management company, introduced his views on the armour structure: from the first contact with the armour structure in the heart of the bottomless, raised a lot of questions, through the technical support of the headquarters of the OPEN headquarters, and continue to understand where the advantages of the system, from the cost savings, the security of the security have practical benefits.

OPEN's team, in the face of the unfavourable conditions of abnormal local weather and heavy rainfall, had the commitment, did not give up, and bravely faced and overcame the difficulties step by step.

Thematic Reports

Mr Wu, Chief Engineer of OPEN, gave a keynote report, introducing in detail the technical characteristics of the armour structure.

Project Manager Li, the person in charge of the project, introduced the construction progress of the project.

On-site Observation

Observation is divided into four teams, each team is equipped with a lead team lecturer and assistant, led to carefully observe the main body of the CS-Frame System , nodes and other structural parts, the design and application of the design and installation of the construction and other issues raised by everyone made a detailed answer.

Afterwards, they came to the lifting area and watched the lifting process of the armour beams, and were impressed by the safe, fast and efficient construction method.

Expert Commentary

This observation meeting also specially invited Professor Tong, a doctoral supervisor of the School of Architectural Engineering of Zhejiang University.

Professor Tong explained the role and advantages of corrugated steel sheet from the structural principle, illustrating the concept of saving steel consumption and using good steel on the knife edge, and obtaining better economy while meeting the structural requirements. With out-of-the-box thinking to find new breakthroughs for traditional technology, we expect OPEN will have more innovations in the future and contribute to the development of the industry.

Mr Lin, Chief Structural Engineer of Guangdong Provincial Architectural Design & Research Institute Co., Ltd. shared his feelings about the crust structure and the visit with the audience. Through continuous communication and Q&A with Mr Chen, he gained a more comprehensive understanding of the technology of crust structure. Mr Lin also suggested that due to the concrete inside the crust structure, the fireproof performance has been greatly improved, and in terms of fireproof coating can actually be omitted or made thin, so that the crust structure can be better promoted.

Interactive Exchange

The site visit was followed by an interactive exchange session. In response to the questions raised by everyone, Mr Ye, Vice President of OPEN, gave professional answers one by one, combining example demonstrations with data comparison.

Since the launch of the CS-Frame System, the cumulative completion of the project more than 3.5 million square metres, its suitable for large-span heavy-duty structural characteristics, the advantages of no formwork and no support to reduce the overall cost, has been the affirmation of many industry insiders and customers and praised, OPEN is also looking forward to working with the industry, sustained innovation, win-win co-operation, to customers, and to create more value for the community.
