The concept of construction 4.0 consists of building information modeling (BIM), artificial intelligence (AI), Internet of Things (IoT), 3D printing, and others. Construction 4.0 concept is used to make human activities simpler. The inclusion of internet-connected devices in the construction industry or IoT in construction has benefitted the industry by reducing operational costs, enhancing productivity, and efficient project management. Construction 4.0 encompasses 3D printing, drones, sensors, virtual reality, and robots for repetitive and hazardous process and to avoid human errors.

Building Information Modeling or Building Information Management (BIM) is often termed as software or a process of generating 3D models of a building or structure to ensure efficient designing, planning, and construction of the project. BIM software is majorly aimed for architects, engineers, and construction (AEC) users. The report on the global BIM in construction market presents a detailed analysis of the trends, future estimations, and thorough study of the market on the basis of phase of work, end user, application, deployment model, and region. Depending on phase of work, the market is classified into construction and operation. According to end user, it is categorized into engineers and contractors. On the basis of deployment model, it is bifurcated into on-premise and cloud-based. According to application, the global BIM in construction market is divided into residential and non-residential.

钢铁行业是我国国民经济的支柱性产业，是关系国计民生的基础性行业，在我国工业现代化进程中发挥着不可替代的作用。但中国钢铁产业也面临着一系列问题，如产能过剩矛盾加剧、自主创新水平不高、资源环境约束增强等。尤其是在疫情和复杂的国际形势下，虽然中国钢铁企业已基本恢复生产，但市场持续低迷，再加上进口铁矿石价格大幅上涨，使得企业经营面临困境。钢铁与有色金属行业不断开展自主创新活动，鼓励原始创新，行业自主创新能力不断提高，取得了众多创新成果。

Buildings are responsible for up to 24% of greenhouse gas emissions and account for over 40% of the world’s total primary electricity use. These numbers are increasing YOY due to the rising world population and improving living standards. The global landscape will be confronted with energy shortages in the future, in addition to the unfavorable repercussions of climate change. It is evident that the present energygeneration system is not sustainable. There is a dire need to shift to renewable sources such as solar power for clean and sustainable energy.
