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.

The systematic material and labor management planning should be established on accomplished EVM data. The matrix method of integrated cost and schedule was used with common category concept according to the construction project control system. The construction project control system was suggested through analyzing process and data modeling based on integrated cost, schedule and material. Information of construction project can be developed the relationship between the field data and the integrated cost, schedule database. Process and data modelling is provide a standard data format which are related to the material, labor management based on integrated cost, schedule database.

사회적으로 여성의 지위가 상승하고 역할이 강조되면서 거의 전 산업분야에 걸쳐 여성의 진출이 매우 활발해지고 있는 실정임에도 아직 건설업에 있어서 여성의 역할이나 참여도는 매우 낮은게 현실이고 또 기존의 건설업에 참여하고 있는 여성근로자들도 단순 사무보조 또는 단순 일용노무직에 불과한 현실이다. 여기 약 20여개의 현장을 공사규모, 종류, 기간, 금액, 각각의 시공사별로 표본 추출하여 각 현장의 안전관리자들에게 설문 받은 내용들을 보면 건설업에서의 여성근로자들이 얼마만큼이나 안전, 보건상으로 소외되고 관심밖에 있는지 잘 나타나 있다 하겠다.(중략)

Construction labor provider system is requested system by professional construction companys of profitless caused by directly hire of construction labor and labor management of difficulty after construction participants system abolition. Complemental laws which occured problems of Payment of wages, illegal subcontracting In construction participants system is prepared and no complemental point included in revised bill. but Construction labor groups oppose introduction of Construction labor provider system because groups concern to occurr before problem in construction participants system. The purpose of this study is drawn satisfactory system to Specialty contractor and construction worker.

Real time location (RTL) system which can control the safety of laborers in the underground space is developed in this study. This innovative system can monitor the location and history of movement of multiple laborers in real time. To accommodate constrains of the underground space, the system is portable and composed with low-battery mode. Since conventional method to detect the location of laborer with radio signal strength indicator (RSSI) contains high errors, new measurement system using accelerometers and correction method are suggested in this study. Field test is performed to validate the developed system. The error for moving laborer was 0.4 m and for non-moving laborers was 0.2 m. Thus, it is found that the new RTL system can be used to monitor the location of laborers in the underground construction space.
