Template for Prefabricated House Renovation Plan
Prefabricated house renovation plans need to be formulated according to different scenarios and requirements. Below are three sample plans for the renovation of prefabricated houses in Sichuan, custom-made construction of prefabricated houses, and the renovation of prefabricated houses before photovoltaic installation:
Renovation Plan for Prefabricated Houses in Sichuan: The overall approach focuses on ensuring safety, improving functionality, and enhancing resilience, integrating into the urban renewal framework and adhering to the principles of 'safety first, classified strategies, green and low-carbon, and co-construction and sharing'. The renovation targets urban prefabricated houses built before the end of 2000 that have structural hazards or functional defects, with a focus on old industrial bases such as Chengdu, Deyang, and Mianyang, as well as earthquake-prone monitoring and defense zones. The inspection and assessment are carried out in five steps: collecting information on the construction year and structural form; conducting on-site inspections focusing on the connections and cracks of prefabricated components; performing structural testing and seismic evaluation; establishing an electronic file for each house after comprehensive assessment. Renovation should be tailored to local conditions, implementing 'one policy per district' and 'one policy per building' based on different geological conditions, structural types, and degrees of damage, while respecting residents' wishes by allowing them to decide on the plan and supervise the process, prioritizing the use of cost-effective, green, and low-carbon reinforcement techniques and local materials.
Custom-Made Construction Plan for Prefabricated Houses: Construction preparation includes site leveling, setting up temporary facilities, and ensuring smooth construction roads; organizing teams such as project managers and construction workers and providing technical training; purchasing prefabricated components and auxiliary materials such as steel bars and cement. In terms of construction techniques, foundation construction requires leveling and compacting the foundation, making formwork, and pouring concrete; transporting prefabricated components using appropriate tools to ensure safety and stacking them in order during storage; assembling components such as walls and roofs according to the design sequence using bolts or welding; and carrying out indoor and outdoor decoration, including indoor facilities such as walls and floors, and outdoor facilities such as doors, windows, and stairs. Quality control involves managing raw materials, construction processes, and concealed work acceptance; the schedule is estimated to be 15 days for foundation construction, 5 days for component transportation and storage, 20 days for assembly, 30 days for decoration, and 5 days for acceptance, with a total cycle of 85 days; cost control is achieved by strictly purchasing materials and合理安排人员 (arranging personnel reasonably) to improve efficiency.
Renovation Plan for Prefabricated Houses Before Photovoltaic Installation: For the renovation of old prefabricated flat roofs, indoor load-bearing steel beams can be added to disperse the load, or a fine aggregate concrete reinforcement layer can be poured on the roof and the waterproofing redone; for rusted and deformed color steel sheds, lightly rusted areas can be sanded and painted with anti-corrosion paint, while severely rusted areas should be replaced with thicker color steel and a load-bearing framework erected; for brick-wood tiled houses, rotten wooden components need to be replaced and tiles repaired, with concrete load-bearing piers poured for the photovoltaic support columns; for roof waterproofing renovation, priority should be given to improving the waterproofing system and adding sealing protection at the locations where support brackets are drilled; for household wiring, the load capacity of the wires should be assessed, the main line specifications upgraded, and the renovation carried out by certified electricians.
