Robot technology is a remarkably interdisciplinary research area, one that can be employed in various industrial fields as well as higher value-added fields. The construction industry, on the other hand, has been known as one of the most difficult research fields to apply robotic schemes. Therefore, applying robot technologies in the construction industry is quite a challenging topic. This paper aims to introduce the progress of automated robotic systems in construction fields, namely with respect to construction robots. While construction robots have a very wide range of application depending on the huge market size of the construction industry, there still exist a lot of problems such as highly risky working environment and inefficiency due to the labor intensive characteristic. In order to solve these problems, a variety of construction robots have been developed and, in this paper, the current state of the robotic systems for construction works and the vision of future robot technology in the construction field are introduced.

Metaverse refers to a digitally expanded world by combining real and virtual spaces. As reality expands into the digital world, various things that were not possible before are possible with the aid of the system, and its usefulness is spreading metaverse rapidly regardless of industry. In particular, it is relatively easier to display information from the virtual world over the real world than to bring information from the real world into the virtual world, which is why most industries are pursuing a metaverse using AR(Augmented Reality). The construction industry also tried to introduce the AR metaverse except in certain fields such as education, but it is being used only limitedly due to the limitations of AR devices. The disadvantages of AR devices, which are sensitive to afterimage effects, narrow viewing angles, and environmental influences, are the main reasons that make AR challenging to use in actual workplaces, not only in the construction industry but also in other industries. So as the technological maturity of VR(Virtual Reality) devices increases, VR will gradually replace AR. Therefore, in response to future changes, the construction industry should plan metaverse technology development using VR devices.

Compared to the other industries, construction industry depends many parts of production activities on manpower. And also 3D perception on construction industry and the shortage of motivation in construction workers are the biggest reason to reduce construction productivity. So to solve this problem, the research of factors which affect more to improve the construction workers attitude in construction site will be needed. This research has investigated that the productivity and important factors was divided to economic factors, social factors, psychological factors. The result show that economic factors remain pre-eminent in influencing productivity, but that social factors and psychological factors appear to be of increasing importance in this construction industry.

This study compared the labor productivity of the construction industry to the manufacturing and service industries. In addition, It analyzed the construction labor productivity gap of the G7 countries based on data from the Korean Productivity Center. A comparative analysis of construction labor productivity between manufacturing and service industries, based on statistics from the National Statistical Office, revealed a relatively low level and trend of continued decline. In addition, a comparative analysis of the productivity of construction workers in the major G7 countries found that the difference in productivity is very large, with an average of 65.3 %. Therefore, domestic construction companies and the government should prepare Improvement measures to improve productivity by investing in technology development to increase labor productivity and improving the production system of the construction industry.

The central issue in this particular research is the seemingly inadequate achievement of optimum performance in the construction process, either with respect to value for money for the client and the entire construction supply chain or value in terms of the utility derived from built assets in spite of efforts by government and governmental bodies such as the Construction Industry Development Board (cidb) to increase industry performance. Therefore, based upon an extensive review of related literature, the paper reports on effects and causes of non-value adding activities in the construction industry in general, and South African construction in particular. The research findings indicate that activities that can be referred to as non-value activities are not only prevalent, but they can also be held responsible for performance related issues in terms of cost, time, quality and health and safety (H&S) in construction; and the exploration of pluralism in the research methodology may result in a robust model based upon the system dynamics approach.

The construction guarantee market is a rear market affected by changes in the construction industry and market. As the restructuring of the construction industry's production system is being carried out, such as the abolition of regulations on business field between general and specialty contractors, major changes are expected not only in the construction market but also in the construction guarantee market. In construction guarantee market, there are currently three Contractor Financial Cooperatives, which are divided based on business field and business type(General, Specialty and Plant & Mechanical). The abolition of business field regulation will have various effects on construction guarantee market, such as forming a competitive structure among the three Contractor Financial Cooperatives. Therefore the role of the construction guarantee institutions are also required to change. This study predicted the changes in the construction guarantee market after the restructuring of construction industry and analyzed the ripple effect on the market. This study reviewed the details of the reorganization plan on the construction industry, policies and statistical data related to construction guarantee, and lastly conducted the survey on each member of the three Contractor Financial Cooperatives to analyze the usage behavior in the future guarantee market. Based on the result of this study, the members of both the General Contractor Financial Cooperative and Specialty Contractor Financial Cooperative are not willing to change the existing institutions, but a lot of them are expected to use other institutions in duplicate. The members of the Plant & Mechanical Contractor Financial Cooperative are most willing to use other guarantee institutions.
