Labor management has been considered as an important task in construction industry. However, labor management has not yet been systematically performed because of the wide variety of factors of construction industry such as the field work, the complexity of the work process, the daily employment. Most of the present labor managements are performed to collect the information of the number of labors input during the work period, and to calculate labor cost. The information of activities performed by labors can be effectively used to analyze project status related to schedule, cost and productivity, but the present labor management systems are not based on the activities. The main objective of this research is to develop a labor information management system using IT tools in order to measure the number of labors input on the activities, and to convert the labor information into productivity data. It is anticipated that the effective use of the developed system would be able to effectively assist the scheduling and cost management of a project.

건설생산체계 개편의 일환으로 논의되던 시공참여자 제도가 2008년부터 폐지됨에 따라 전문건설업자는 시공참여자에게 재하도급을 주어 노무관리를 일임하던 구조에서 탈피하여 십장 및 그 소속 근로자를 직영 근로자로 고용해야 한다. 이는 전문건설업자의 유.무형 부담을 가중시켜 기업경영의 어려움을 초래할 가능성이 높다. 이와 같이 경영상의 어려움을 최소화하기 위해 전문건설업자가 채택할 수 있는 최선책은 팀제생산방식의 장점을 살리면서 작업능률을 최대한 발휘할 수 있는 건설 노무인력 임금체계를 모색하는 것이다. 이와 같은 건설 노무인력 임금체계로 제2안(팀장과 팀원 모두 고정급형 성과급제 적용)과 제3안(팀장과 팀원 모두 순수 성과급제 적용)이 가장 적합하다. 팀장과 팀원 모두에게 고정급형 성과급제 또는 순수 성과급제를 적용함으로써 팀장(십장)의 긍정적 기능을 유지하면서 건산법 및 노동 관계법상의 근로자 지위를 보장하여 건설 노무인력의 수급안정과 직업 안정성 확보에 기여할 수 있다. 또한 일정 수준 이상의 노동생산성을 확보하여 전문건설업자의 과중한 경영부담을 다소 해소할 수 있을 것으로 기대된다.

In private and public construction works, cost estimation and site productivity management are based on designed labor quantities calculated by the Standard Quantities per Unit (SQU). The designed labor quantities are regarded as the basis for insurance costs and safety and environmental costs and also affect the progress measurement of construction works. Even though the designed labor quantities from the SQU has been considered to be different from actual labor quantities put to construction works, there is no research that empirically analyzes the statistical differences. This study analyzes actual labor quantities of form workers, steel-bar fabricators, concrete pourers in reinforced concrete works of the 43 apartment projects, and compares the actual labor quantities to labor quantities from the SQU. It goes further to scrutinize the critical reasons underlying the differences through a survey on 65 practitioners and interviews with 32 site managers and supervisors. The regression models of labor quantities of the apartment concrete work produced by the present study will contribute to reasonable construction contracts based on the past actual costs and practical site management by the actual labor quantities.

Korea's population change trend is the aging and feminization as Reduction in mortality, average life extension. and is further increased Reduction of birth rate and aging population. if Our country concluded FTA(Free Trade Agreement) with the United States, Europe and China etc. labor-intensive industries will be the decline. Then, the construction workers' jobs are continually reduced. This is critical to the nation's economic, social and environmental influences due to Shortage of construction workforce and increasing labor costs. Eventually this is a major factor in reduced construction productivity. Therefore, this study is presented as a construction productivity development prospects on the value-added analysis per Labour productivity employee from Construction market trends, industry-specific productivity index, industry trends Employed, age tiered workforce trends, women's workforce trends, labor time trend, foreign workers, workforce trends, analysis of trends in construction contract, awarded by Company Size trends, construction management analysis index.

The amount of labor input in a construction project is used as source data to estimate construction cost and to understand the productivity of the construction industry. However, there is a significant difference between the standard of estimation and the actual amount of labor input, and a plan is needed to resolve this problem. For this reason, to establish a system with which the actual amount of labor input can be inputted in a more accurate and simpler manner, a new method is proposed in this study. In the new method, a digital pen is used to minimize the difference from traditional handwriting on paper using a pen, and eliminate the redundant input of information. This study is expected not only to reduce the actual amount of labor input but also to contribute to the productivity of construction cost estimate through the sharing or utilization of the information on the web.

Labor work information can be converted into the useful construction information in an effort to analyze project status, measure performance, and design a new similar project plan. The labor work information can also be used to make productivity data, which can be used to analyze the relationship between 'as planned' and 'as built' in scheduling management of a project, and to calculate 'percent completion' as well as analyzing delay cause. It is require to effectively collect the labor work information base on the activities. In general, current project management heavily depends on the experience and judgment of project managers, according to the work progress. However, relying on the oかy experience and judgment of the project managers might deteriorate the transparency or reliability of the collected labor work information. The purpose of this research is thus to develop a computer-based system for monitoring the work information generated by labors input in activities using PDA and Barcode technologies, and to propose a application method of the productivity data for effective project management.

Construction industry has particular properties of non-continuity of production, and non-stability of market comparing to other industries. Because of them, the practical construction cost is more difficultly recognized than in manufacturing industry, so, that is various according to many projects. Therefore, it is very hard work to standardize construction cost, and it is worthy of analyzing and measuring exactly construction cost. On this study, the trouble in producing expected construction cost with original cost calculation method is progressed by the data of cost items in complete works. On the basis of analyzing data, as expected cost of practical construction is measured, it can be referred to the method and the standard of indirect labor cost rate in construction.

This paper measured and evaluated the technical efficiency, pure technical efficiency and scale efficiency of port labor via three inputs and three outputs using Data Envelopment Analysis (DEA). First, the average overall technical efficiency measured about 94.18 %, with 100 % pure technical efficiency being larger than 94.18% scale efficiency. As a result, 7 ports were identified as efficient, and 4 ports were identified as inefficient. Among the 4 ineffiecient ports, Donghae had the highest Increasing Return to Scale (IRS). However, the inefficient ports were all found to be less efficient in terms of resource operation than production scale. On the other hand, the efficient ports established priorities using the super efficiency method. As a result, port efficiency was highest for Incheon, Mokpo, Pyeongtaek-Dangjin, Masan, Yeosu Gwangyang, Jeju, and Gunsan-Daesan Ports, in order. In particular, Busan Port, found to be inefficient, would benefit from using Mokpo Port and Incheon Port as benchmarks to increase trade volume and modernize equipment for full-scale commercialization to improve labor efficiency.

이 논문에서는 호주에서 한국계 이주자가 다수 취업하고 있는 건설산업의 타일직종의 사례를 중심으로 한국계 이주노동자의 노동실태를 밝힌다. 건설현장의 사례조사를 통해 중층적 하청구조의 말단에 편성된 타일노동조직인 노무재하청업체의 작업방식 및 생산성관리, 숙련구분 및 임금결정, 임금수준 등 기타 노동조건을 구체적으로 규명한다. 그리고 이를 호주의 노사관계에서 제도화된 자영청부방식 및 자영청부공의 노동조건 등과 비교한다. 사례조사는 2006년도에 시드니지역 상업용 건축부문의 타일시공현장 두 곳을 대상으로 이뤄졌다. 두 곳의 건축현장 모두 노조가 활동하는 현장임에도 불구하고 한국계 이주 타일노동자는 공식적인 노사관계제도가 적용되지 않는 무협약상태에 있다. 건설산업의 최저 노동조건이라고 할 수 있는 전국재정 마저도 적용되고 있지 않다. 그들이 공식적인 노사관계제도의 적용으로부터 배제된 근본적인 이유는 타일회사로부터 타일시공을 다시 하수급하는 한국계의 노무재하청업체(오야까따)에 고용되어 있기 때문이다. 타일회사나 빌더는 1990년대 후반부터 다수 유입되기 시작한 한국계 타일공을 이와 같은 노무 재하청방식으로 사용하고 있는 것이다. 건설노조는 확대되는 노무재하청에 대해 한국계 타일노동자를 대상으로 한 여권조사, 임시고용비자 및 타일청부면허 취득 캠페인 등의 활동을 통해 불법취업자의 사용을 금지하는 한편 한국의 타일기능공을 자영타일공으로 전환시켜 노사관계 질서를 세우려 하였다. 그러나 이러한 노조의 활동에도 불구하고 기업협약에 의해서 명문으로 금지되고 있는 노무재하청의 관행이 전혀 개선되지 않고 있다. 노무재하청 관행에 대한 건설노조 정책의 가장 곤란한 문제점은 노무재하청을 행하는 당사자인 재하청업자를 한국계 타일노동자 조합조직의 중심으로 하고 있으며, 또 하지 않을 수 없는 점에 있음을 양국 간의 숙련구분 및 임금제도 비교분석을 통해 밝혔다.
