100년 가는 아파트, 화장실에 달렸습니다 (최도영 고려사이버대 교수/전 DL현장소장)

💡Summary It is explained that the significant increase in construction costs is not merely due to rising material and labor costs, but rather to three structural changes: stricter safety regulations, a shortage of skilled workers, and the increasing complexity of apartment design and regulations. Since the implementation of the Serious Accidents Punishment Act, the responsibilities of site managers and supervisors have increased significantly, leading to a substantial increase in safety management personnel and procedures. Furthermore, as work efficiency has declined due to requirements such as wearing safety belts and maintaining records, both construction periods and costs have increased. However, the contributor points out that they do not oppose safety reinforcement itself, but rather that the current system, which concentrates responsibility solely on site managers, needs improvement. Another cause is the severe shortage of skilled workers. The number of technical personnel in fields such as plastering, tiling, and masonry has decreased significantly, leading to a higher proportion of foreign workers. To compensate for this, construction companies are expanding the use of dry construction methods and precast concrete (PC). However, since certain processes, such as bathroom flooring and screed plastering, still require skilled workers, it is difficult to completely resolve the labor shortage. In addition, it is explained that the continuous strengthening of various performance standards—including those related to inter-floor noise, insulation, ventilation, and smart homes—has made equipment and construction processes more complex, leading to an increase in construction costs. Along with this, the limitations of high-rise apartments and future housing technologies were also discussed. It was predicted that it is difficult to reduce construction costs for high-rise buildings due to structural reinforcement required to withstand loads and wind, as well as the installation of evacuation safety zones, and that the economic feasibility of future reconstruction is highly likely to decline. As an alternative, the concept of "long-life housing" was introduced, which involves arranging piping along the walls to replace only the equipment while maintaining the structural integrity; however, it was explained that this approach is difficult to expand without institutional support because initial construction costs are approximately 30% higher. Finally, it was predicted that the digital transformation of the construction industry—including BIM (Building Information Modeling), PC and modular construction methods, and the use of drones and AI for quantity surveying and rebar inspection—will become key technologies to enhance construction quality and productivity. 📌Key Topics 3 Key Causes of Rising Construction Costs (Safety Regulations, Shortage of Skilled Workers, Complex Regulations) Decline in Skilled Workers and the Spread of Dry Construction and Precast Concrete (PC) Methods Structural Limitations of High-Rise Apartments and Reconstruction Issues Why Long-Life Housing Can Be an Alternative to Reconstruction Future Construction Technology Transformed by BIM, AI, and Drones [This is an AI-generated summary of the video] 👉Understanding Inquiries: [email protected] 👉Read "Understanding Text" https://contents.premium.naver.com/ba... 👉Join Understanding Membership    / @understanding.
