사업의 지속적인 성장을 위해서, 생상성의 향상은 필수적인 요소이다. 건설업은 노동집약적인 산업이고 그래서 건설기능인력은 생산성에 영향을 미치는 가장 중요한 요인이다. 그러나 매해 건설기능인력은 감소하고 있는 추세이다. 따라서 이러한 문제는 반드시 교육체계와 직급체계의 제안을 통해 관리되어져야 한다. 이 연구의 목적은 기존의 문헌고찰을 통하여 현재의 교육체계와 직급체계의 연관된 문제를 찾아내고 이러한 문제를 해결하기 위하여 교육체계와 직급체계를 제안하는데 목적이 있다. 또 이러한 교육체계와 직급체계의 타당성 검증을 위하여 건설 기능 인력의 설문조사와 건설 실무자의 면담, 조사를 통하여 타당성을 도출해낸다. 좀 더 세부적인 사항이나 결론은 아래의 글에서 알아보기로 한다.

Construction is a typical labor-dependent industry. However, problems related to wage payment, which directly affects the livelihood of workers, have caused other problems in maintaining skilled workers, such as increasing the turnover rate of skilled workers, resulting in a shortage of skilled workers. Against this backdrop, this study was conducted to develop measures to improve the conventional wage payment systems in order to prevent skilled workers from leaving their jobs and to maintain them as workers. It is necessary to make the registration of non-registered small-sized construction companies in Korea mandatory, and to introduce means by which construction companies that hire workers through non-registered agents can be penalized. In addition, the project bank account (PBA) system used in the domestic banking sector can be benchmarked in operating payment systems, an approach that is expected to effectively prevent delayed wage payments in the construction industry.

The construction industry is a labor-oriented and quality, cost, and schedule performance is effected by technicians. However, the construction industry have faced a labor shortage problem. Therefore, technician graying and no new workers inflow cause labor shortage and decline of worker's skill level. The utilization of foreign technicians instead of domestic technicians has been increased in the construction industry. This paper performed questionnaire survey for 43 managers on 14 project fields to determine the current status and problems of construction technicians and to propose a improvement plan. As a result, most foreign technicians are carpenters and iron workers, but the skill levels are generally lower than domestics. The major problems for foreign technicians are communication and non-skilled. Then, labor productivity and accident rates of foreign technicians are higher than domestics. This paper proposes that skill training programs, language lessons, and multi-cultural programs are effective to improve foreign workers' problems.

Problems related to wages in the construction industry, which directly affect the livelihood of workers, have caused other problems in maintaining skilled workers, such as decreasing the inflow of new laborers and increasing the outflow of the existing labor force, which has weakened the foundation of industrial production. Against this backdrop, this study aimed to improve the current wage calculation system in order to increase the inflow of new laborers and maintain the existing skilled workers. It is necessary to differentiate the minimum wage in the construction industry, which requires a high intensity of labor, by industry and occupation type. It is also necessary to establish standards for specifically calculating wages, such as holiday work and overtime pay. The standard of the current retirement mutual aid fund needs to be upwardly adjusted at the same time.

Labor shortages are a serious problem for Korea's construction industry. The problem is both quantitative and qualitative. There is a shortage in supply as due to a decrease in the influx of new labor, and existing workers are less productive as they age. The problem will only get worse as more and more major public projects are being planned. Options for increasing the labor supply are somewhat limited, and thus efforts need to be made to adopt new technologies that can improve the productivity and efficiency of field work and their processes. This paper introduces seven innovation technologies that have the best potential to increase productivity and thus reduce the burden of labor shortage problems. These include 1) Substitution by use of robotics and automation, 2) development and applications of Innovative materials to reduce on site field work, 3) increase in productivity through the implementation of Information Technology, 4) improved productivity through the application of modules, and prefabrication, 5) prevention of rework and redesign, 6) diversification of labor by integrating labor skills, and 7) improved productivity by standardizing site processes.

The Construction industry is a labor-intensive industry that its labor cost takes up about 30~40% out of the whole construction cost. However, due to a stereotype that on-site work is a 3D job there is a shortage of the labor forces. Modular construction method is to produce modular units in the plant so that workers could work stably. Also, after delivering the module from plant to the site, there will be only installment to be required that shortens construction duration. Even though the modular market is currently expanding based on military facilities in Korea, its best strengths are not demonstrated well which are shortened construction period and low cost. It also causes labor problem of production due to minimum utilization of the modular construction method. Multi-skilled labor means a technician that is able to perform more than two kinds of work with more than two techniques. Multi-skilled labor can proceed smoothly by figuring out the connectivity between the precedent and following operations. Therefore, this research is to apply the concept of Multi-skilled labors, suggest solutions and allocate manpowers efficiently. As a result, it helps to decrease idle manpowers during the operation and the total labor forces can be saved. Low cost is the original strength of the modular which can stand out so the modular market is expected to expand.

The construction industry is heavily dependent on labor force as automation to building constructions is difficult due to its characteristics such on-site production, custom manufacturing production. Thus, while securing and fostering high-quality functional manpower for stable construction work are significant, the construction workforce has been persistently lacking compared to demand. Young workers are reluctant to enter the construction industry due to high labor intensity, unstable employment structure, and uncertainty for the future. The employment rate for new jobs in the construction industry is half as high as in others. Currently, the departments related to construction are organized in specialized high school to conduct training for young workers. The graduates have a low ratio of employment rate to the construction industry and functional capacities fallen short of expectations. In this study, the education and training conditions of specialized high schools were analyzed to derive problems and key improvements of the education system were drawn. As an improvement for the analysis results, it provides solutions such as giving advantages of previous education experience, expand industry-academic cooperation with businesses, and expand links with external educational institutions.

Currently, the construction industry is decreasing every year due to people's poor perception, high labor intensity, unstable employment structure, and welfare problems, as people avoid entry. Accordingly, this study investigated how to attract trainees and graduates from domestic construction education institutions to the construction industry. If institutional devices are prepared to prepare for the future by improving the welfare system such as unemployment benefits and retirement deductions in the construction industry, many trainees in their 20s and 30s will be attracted to the construction industry. If it helps expand hands-on education through on-site linkage and has the necessary technical skills for practice, it is believed that trainees and graduates in their 4s and 60s will be attracted to the construction industry.

Recent decrease in the availability of experienced skilled labor and a corresponding lack of new entrants has required the need for automating many of the construction equipment used in the construction industry. In particular, excavators are widely used throughout earthwork operations and automating its tasks enables work to be performed with higher productivity and safety. This paper introduces an optimal path generation method which is one of the core technologies required to make "Intelligent" excavators a reality. The method divides a given earthwork area into unit cells, identifies networks created by linking these cells, and identifies the optimal path an excavator should follow to minimize its total transportation costs. In addition, the method also accounts for drainage direction and path continuity to ensure that the generated path considers site specific conditions.

Construction that over 70% of the structure consists of concrete gets bigger and higher gradually and the demand of that is increasing as well. However, it's not easy to supply young and skilled persons on construction site because of social avoidance phenomena about 3D occupation, so it causes serious problems like aging and shortage of technicians. To solve the problems, executives related to the construction field make a management effort in various ways such as construction period shortening, labor productivity improvement and good quality but recently, they have an increasing interest in the necessity of the modularization of the high-rise building and the automation of the engineering development for the strengthening of international competitive power as more active and long-term alternatives. Therefore, this study is to propose the roadmap in order to make lots of efforts in developing construction technologies of high-rise buildings by performing a foundation study, the strategy for 4-step research development, on modularized construction system of concrete structure of high-rise buildings through domestic and foreign preceding research analyses associated with optimal design modularization technique, module factory automation and assembly automation of modularized objects.
