In the field of prefabricated construction, it was stated that “We shall strive to achieve a proportion of 30% of prefabricated construction in the new construction within about 10 years” in the Opinions on Further Strengthening the Management of Urban Planning and Construction issued by the State Council in 2016. The Group has actively responded to the call of national policy and has been committed to promoting its development in recent years. It paid high attention to the prefabricated technology in the front-end investment design field of the main business of real estate, meanwhile established a construction industrialization resource service provider that integrates design and production, Shanghai EPC Construction Technology Co., Ltd., continuously exploring multi-dimensionally and putting efforts to promote the practice and innovation of prefabricated construction.
With the four major features of “standardized design, factory-like production, information management, equipment-type construction”, the Group’s prefabricated construction brings several environmental benefits such as reducing energy consumption, water consumption and noise pollution during construction, and can effectively respond to the call for environmental protection and energy conservation advocated by the state. At the same time, it can also solve the problems of unstable quality reliability and long construction cycle, so as to improve safety and quality of the products.
In 2020, the Group’s utilization rate of prefabricated construction (prefabricated project) accounted for 66% of our new projects, which was higher than the national policy target. The Prefabricated Sandwich Thermal Insulation Shear Wall Structure System was adopted for the ongoing Pujiang Major Residential Community Expansion Project in Pujiang Town, Minhang District, Shanghai, while the outer walls, bay windows, air conditioning panels, internal and external shear walls, balconies and staircases are prefabricated in factories and assembled on site, and prefabricated composite floor slabs are adopted. The overall prefabrication rate accounts for more than 40%, which greatly improves the project quality and construction efficiency, effectively reduces the waste of construction materials, achieving a good effect of energy saving and emission reduction.

Fuzhou Olympic Sports Project
Fuzhou Olympic Sports Project site comprises three buildings which are in the Historic Buildings Census Results List and need to be relocated. In order to protect the remaining historical information of these buildings as much as possible, the Group plans to relocate them nearby. The original nature of settlement shall be preserved to the largest extent. Considering the inherent connection nature, the Group plans to locate them close to each other. The following aspects are mainly considered in space deployment:
1. Protect the original information of the buildings as much as possible - consider the connection nature and the adjacent location of two of the buildings.
2. Preserve the original planned green corridor - reserve the east-to-west corridor to maintain the connection between green lands.
3. Consider the space relations of surrounding buildings as a whole- build an interactive connection by connecting buildings with lanes and squares.
4. Add new functions- recreational service buildings in the park.
Fuzhou Rongchen Mansion
During the development of Fuzhou Xindian Project, the Group found an ancient banyan tree which is about 200 years old within the plot, whose crown and root system affected the construction and basement layout of the project. As the relocation may cause unforeseeable impact, the Group decided to protect its original site. The Group amended the design of the project, deploying the construction and basement away from the banyan tree. In order to prevent the root system of the banyan tree from being damaged, the Group abandoned the normal bolt support form, and instead, adopted a support solution of a vertical cast-in-place pile support of a length of 13m, plus interchangeable support beam, together with reinforced concrete support, where the banyan tree is firmly surrounded to avoid any damage to the tree during the project construction.
Although these measures have caused a significant impact on the project cost and progress, a peaceful environment has been returned to the banyan tree, making it continue to shelter our future owners after 200 years of changes.

Shanghai East China Normal University Bookstore Renovation Project
Shanghai East China Normal University bookstore renovation project is located on the bank of Liwa River in East China Normal University. It is located in the core teaching buildings area and the center of the cross space axis of the whole campus. As a single-storey building where the original teaching material warehouse was sited, it could not fully meet the functional requirements of the book bar. Therefore, with the original architectural structure being kept, functions of the book bar were improved through local addition, which responds to the surrounding environment and regional context. The original slope-shaped building roof was preserved in the overall renovation. Through the placement of glass house and steel frames, it helps make up for the lack of original space, while directing to the entrance. The book bar provides comprehensive functions by integrating reading, exhibition, tea tasting, rest and others, and retains the original building structure by partially expanding the second floor and adding a glass house at the entrance to meet the new functional needs. The additional glass house serves as the buffer space at the entrance of the book bar, which also makes up for the lack of original indoor area. By utilizing the space under the eaves of the sloping roof, local interlayer is placed to improve the insufficient functional space of the original functional space for teaching material. On such basis, the private space for meditation and communication is created as opposed to the open space on the first floor. In terms of functional layout, the first floor, as an open space to make full use of the landscape resources along the river, provides a panoramic view alongside the river, in which it sets up the reading and communication space, as well as providing coffee, refreshments and other light meals to meet the needs of readers. The inner side as a quiet reading space is divided into public and private spaces by the staircase in the middle. The obvious function division that user can find the sense of existence and belonging in the book bar. At the same time, the installation of a side court would enhance layering of the original rectangular space.
In the design for restoration of the side pavilion, the original glass doors and windows are removed to open up space while the pavilion framework is retained to a large extent. When restoring the base, it is renovated by application of folding lines, similar to that of a sculpture, representing the boat of history that carries the glorious history of East China Normal University, which also symbolizes a lamp with an ever-burning candle of hope floating on the river.
