As blue-collar construction workers are the critical source among production factors of the labor-intensive construction industry in Korea, the improvement of the labor environment including employment stability, realistic remuneration are emergently required. In view of this, the study, based on the associated primary data, attempts to analyze installation condition in construction sites and installation criteria in a large-sized construction company on the convenience facilities for construction site workers, and to investigate satisfaction level of the blue-collar construction workers on that ones. The study further suggests some realistic informations upon which the efficient improvement measures for the blue-collar construction workers possibly are prepared. The results of this study are provide practical basic data for establishment of realistic as well as reasonable policies/programs for the working milieu improvement.

Although the life-spans of most apartment buildings are over fifty years, they are often demolished and retrofitted only after twenty years, in spite of its remaining life expectancy, resulting in economical waste. The purpose of this paper is to estimate optimum remodeling period of apartment buildings using total cost. In this study it is seen that total sum of running cost of life-span on the buildings is about 4.69 times of initial cost till the fifty years of the life expectancy. The optimum remodeling period of the apartment building is thirty years applying the discount rate of $4.17\%$ and the discount rate should be $6.122\%$ to obtain the forty years of the optimum remodeling period. From the sensitivity analysis based on the change of the discount rates, it is seen that if discount rate decreases the optimum remodeling period can be extended, or vice versa. As a result, a time of the demolished and remodeling can be expected and the basic data can also be established for lengthening life-span of the apartment buildings. 일반적으로 공동주택의 수명은 50년이지만, 보통 20년이 경과하면 철거되거나 재건축되어 경제적인 낭비를 초래하고 있다. 이에 본 연구는 LCC이론을 기초로 초기투자비와 경과년수에 따른 유지관리비용의 합이 최소가 되는 시점을 추정 $\cdot$ 분석하여 공동주택의 적정 리모델링 시기를 도출함을 목적으로 하였다. 본 연구의 결과를 보면 내용년수 50년까지의 건축물의 생애 총유지관리비용의 합은 초기투자비의약 4.69배가 되고, 공동주택의 적정 리모델링 시기는 할인율 $4.17\%$를 적용했을 경우 30년으로 파악되었으며 서울시에서 발표한 법정허용년수인 40년이 경제수명으로 설정되려면 할인율은 $6.122\%$가 설정되어야 한다. 또한 할인율 변동에 따른 민감도 분석결과 할인율이 감소할 경우 적정 리모델링 시기는 연장되며, 증가할 경우 단축되는 것으로 나타났다. 이에 본 연구의 결과는 공동주택의 철거 또는 재건축 시기를 예측할 수 있으며, 보수 및 대수선의 적절한 시기를 예측하여 공동주택의 수명을 최대한 연장시킬 수 있는 기초자료로 활용될 수 있을 것으로 기대한다.

국내 CM시장이 활성화됨에 따라 경쟁이 심화되어 실제 프로젝트 관리를 담당하는 CM단장의 능력은 CM사업 수주를 위한 중요한 요소가 되었다. 이로 인해 각 CM전문회사는 유능한 CM단장의 확보를 위해 현재 담당 프로젝트가 없더라도 후속 프로젝트의 수주를 위해 CM단장을 일정수 대기상태로 확보하고 있으나, 효율적인 활용방안에 대해서는 체계적인 방법이 마련되지 못한 실정이다. 이에 본 연구는 현재 CM전문회사가 보유하고 있는 대기상태 CM단장들의 활용실태 및 문제점을 분석하고, CM단장의 효율적인 활용을 위한 개선방안을 모색하기 위한 실무적 기초자료를 제시하고자 하였다. 본 연구결과, CM전문회사의 현재 대기상태 CM단장 인력수는 적정 비율 및 인력수에 비해 약 2배 정도 많은 것으로 나타났고, CM단장의 선정기준으로 프로젝트의 수주를 위해 프레젠테이션 능력을 가장 중요한 요소로 고려하고 있었다. 그리고 대기상태 CM단장의 보유 및 활용상 문제점은 크게 고용비용 증가와 현장 및 본사 업무지원능력 부족 및 제한적 활용으로 요약되었고, 대기상태 CM단장의 효율적인 활용을 위한 현장 및 본사 기술지원과 수주능력 강화 및 제도개선 등에 관한 개선방안을 제안하였다. The number of construction management firms has been increased as construction management delivery system has been active in Korean construction market. the capability of leading construction management professional, who is responsible for managing project administration, is important for commissioning construction management contracts. The quality of project proposal and the capability of leading construction management professional, which are assessed by the board of contract awarding committee, are the major contributors for commissioning the public construction management projects administered by the Korean public procurement service for contracting. Therefore, employing a very competent leading construction management professional is the critical strategy for awarding contract to the construction management firms' part. That is why the firms should secure a fixed number of leading construction management professional in a waiting list to proceed the contract commissioning process for expectant candidate projects, even if there is no project assignable to the leading construction management professionals. However, a measure that makes effectively use of the leading construction management professional in a waiting list has not been systematically implemented in the firms. In turn, the firm suffers considerable loss in a project personnel supply and demand plan. Expert opinions were obtained by the survey questionaries administered to top management of the construction management firms which are engaged in the construction management contracts for commissioning the public construction management projects administered by the Korean public procurement service either as principal or co-principal deliverer. This paper presents the findings obtained by investigating the actual employment state of the leading construction management professional in the waiting list and by analyzing the issues involved in mobilizing and demobilizing them. It contributes to implement a practical guide for searching effective solutions to the issues.

This paper presents a simulation model that facilitates to analyze and estimate both time and cost of the steel erection operation making use of tier construction method. By conducting motion and time study, resource processes of the operation and their tasks of the processes are defined. These atomic tasks are used as a building block to implement a simulation model that reflects the real world steel erection operation assembling the steel material in the job site. Task based operation simulation model deals with local variables or delay factors affecting productivity and improves the reusability of existing production models. Therefore, the proposed approach allows the model to adjust more easily to construction method change. The proposed steel erection model was verified by comparing with the Construction Standard Production Unit system (CSPU) and daily work report.

Recently, as the characteristics and production methods of the construction industry are changing, and women are actively entering the society, the view of women in the construction industry is also gradually changing. Although the government is currently improving the system to expand women's participation, nevertheless, women's participation in the construction industry is very low compared to other industries. The scope of this study was limited to presenting the actual working environment and improvement plans for male and female engineers in the design office. As a result of the survey on the insufficient part of the work environment, the item 'rest space such as lounge, bathroom, and conference room was narrow' was highly surveyed for men, and 'there was no rest space that required gender discrimination' was highly surveyed for women. As for the improvement measures, both men and women were surveyed highly in the category of 'My place for personal work'. In this study, the scope of the study has a limitation in that it only presents the actual situation and improvement measures for the working environment for male and female engineers in the design office.
