Through literature search and analysis,the permanent and temporary combined construction technologies adopted in 65 construction projects in China were classified into 6 categories and 21 items,and the application of differ-ent technologies was analyzed.Research has found that civil engineering and water supply and drainage are currently the main categories of permanent and temporary construction technology in construction engineering.Among them,the per-manent and temporary construction technology for construction roads is the most widely used,and it is evenly distribu-ted in public buildings,residential buildings,and industrial buildings.The pilot application of fire pipeline permanent and temporary lighting without laying pipes or bare wires technology in a public building in Beijing had achieved good environmental and economic benefits.Based on the analysis and application of permanent and temporary construction technology,four points for attention were finally proposed.
