Prefabricated Concrete Slabs in Xiongan New Area
The following is an overview of prefabricated concrete slabs in Xiongan New Area:
Widespread Application of Prefabricated Components in Modular Construction
In Xiongan New Area, modular construction methods are being vigorously promoted, with prefabricated components playing a crucial role. Building elements such as walls, floor slabs, stairs, and utility tunnels are all prefabricated in factories and then transported to construction sites for assembly according to design drawings, much like assembling car parts. Hebei Xiongan Prefabricated Component Technology Co., Ltd., currently the sole producer of modular prefabricated components in Xiongan New Area, undertakes the manufacturing, production, and installation of these components for various construction projects in the area. Prefabricated components are visible in key construction projects such as the startup zone, initial development zone, and the resettlement areas of Rongdong, Rongxi, and Xiongdong, indicating their significant position in the construction sector of Xiongan New Area.
Update of Architectural Specimens from the Era of Prefabricated Slabs Nationwide
Nationwide, architectural specimens from the era of prefabricated slabs are facing updates. Houses built with perforated slab materials are products of a specific historical period, and their seismic performance no longer meets current regulatory requirements. For example, during the ancient city renewal process in Shaoxing City, a total of 1.32 million square meters of prefabricated slab houses built before 1980 were completely replaced and rebuilt using modular construction technology.
Principles for Handling Prefabricated Slab Houses in Xiongan New Area
Although there is no explicit mention of specific handling methods for prefabricated slab houses in Xiongan New Area, following the principles of the State Council's "15th Five-Year Plan for Urban Renewal" which advocates for "a combination of retention, renovation, and demolition, strictly prohibiting large-scale demolitions and constructions," the fate of prefabricated slab houses will be determined based on their current "health report" and assessment according to the existing "Standards for the Appraisal of Dangerous Buildings." For structurally stable Grade A and Grade B buildings, the mainstream approach is routine maintenance and renovation of old residential areas; for Grade C dilapidated buildings with local hazards, seismic reinforcement is prioritized; only Grade D dilapidated buildings with a collapsed bearing system and at immediate risk of collapse will be included in the list for demolition and reconstruction.
