This study was intended to present measures for the improvement of the apartment house landscaping supervision system by examining the adequacy of landscaping supervision, which is aimed at improving the quality of landscape plants and facilities in apartment house landscaping sites. Additionally, this study aims to identify the problems occurring in the process of the performance of landscaping supervision and to provide the evidence for legislative activities and revision of the laws currently being pushed forward for the mandatory deployment of apartment house landscaping supervision personnel. The results of the analysis showed that no landscaping supervision personnel was deployed to apartment complexes with less than 1,500 households and that the landscaping comprised 19% to 46% of the entire construction process. The civil engineering firm performed the landscaping supervision, which made it impracticable to fully focus on the construction quality in the field of landscaping. The quality control in terms of landscape plants revealed differences in quality control, depending on the competence and experience of the civil engineer supervising the personnel, where the landscaping supervision personnel was not deployed. The apartment houses landscaping supervision activity index was analyzed, and the results showed that the supervision activity index for apartment house A was 72.0, B was 70.4, and apartment houses C to G ranged from 38.7 to 46.9, which suggested that the difference in quality control, process control, and technical support affected the construction quality and occurrence of defects.The improvement of landscaping process quality control and process management will be carried out more smoothly and the rate of defects will be drastically reduced if the landscaping supervision personnel placement threshold is lowered from 1,500 households to 300 households in complexes. The results of this study are expected to be useful in promoting and re-establishing the landscaping industry based on the improvement of construction quality in the field of landscaping in connection with the construction of apartment houses.

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.

Construction performance and productivity improvement are key focus areas in construction industry for any nation. There have been frequent delays and cost overruns in construction projects and poor productivity is one of the major contributions. For this reasons, there have been many research studies performed on the improvement of construction productivity for several decades. However, measuring productivity on a construction job site is still not an easy work. Because collecting reliable data consistently from the job site requires a lot of personnel efforts causing extra time and cost. This paper provides a basic study on the application of image processing technology for measuring unit productivity. It presented the possibility of unit productivity measurement by image processing technology through case study.

Project-based joint ventures are often used in the construction industry to assemble an organization that meets a client's project needs and matches or exceeds the capacities of competitors. The joint venture / partnerships provides the means for a firm to quickly add resource, political, technical, or other required strengths that will increase project acquisition. This paper sets out to study the types of joint ventures, different issues or problems while having joint ventures and the critical factors that contribute to successful joint ventures. A questionnaire was designed and administered to survey the issues and present practices of joint ventures in the South Florida construction industry. Along with the questionnaire, personnel interviews were also conducted to get first hand knowledge about the subject matter. The results are presented in the paper. These results specifically identify the overall practice of joint ventures in South Florida as well as indicate the most significant factors leading to failure or success of these ventures.

Organizational personnel must have well-developed interpersonal skills to deal with the different stakeholders and departments, to work at different levels in the hierarchy, and to meet varying performance requirements. Many leadership development and mentoring programs are designed to expose students as well as construction professionals to contemporary leadership techniques and skills. Leadership skills generally separate into three decision-making styles with varying degrees: 1) Autocratic, 2) Participate, and 3) Free-rein. This paper describes the study of leadership styles among 174 construction professionals and addresses the most appropriate leadership style for a project executive and a project manager in relation to compare with the characteristic leadership style and job functions. The study supports the growing importance of leadership skills as a component of managerial functions and provides a benchmark to identify a dominant leadership skill for a specific managerial position.

The majority of construction site incidents occur due to a lack of hazard awareness among workers on job sites. This lack of awareness is despite mandatory construction safety training, typically in the form of written content (safety manuals) or of images depicting hazards. To reduce job-site injuries and fatalities, general contractors have started adopting Virtual Reality (VR) to impart safety training to job site personnel. VR safety training can take the form of an immersive simulation comprising potential safety hazards intentionally embedded into a virtual job site; users are required to identify these hazards within a specified time frame with the expectation that they will be more adept at recognizing hazards on an actual job-site, resulting in fewer accidents. This research study seeks to identify the actual impacts of VR on construction safety awareness among participants. The research addresses the following question: Does VR improve hazard recognition awareness? The primary objective is to evaluate participants' performance of past construction safety awareness against present construction safety awareness after receiving VR training. Participants were asked to complete a multiple-choice Qualtrics™ questionnaire. The results of the study showed a statistically significant knowledge gain advantage with respect to hazard recognition and construction safety awareness with the use of interactive, immersive VR over a more conventional and passive safety training method.

In this research, I finally came to a conclusion analyzing the connection among managing of each items in management expenses, the size of each complex and stories, and the term of using. (1) In the managing cost regarding to the management manner, although the managing cost of self-governing management is less imposed than the one of commission management, there is slight difference between those Costs. And it is more important to consider the effectiveness of management than to emphasize reduction of management cost. (2) The higher the stories, the higher the managing cost of elevator per the unit area. It Is caused by the fact that the father the distance of the elevator operating, the higher the electric charges. (3) The third of one of total management cost goes to pay the personnel expenses. So I found that the effective management of the expenses is available to reduce management cost. (4) The higher the stones, the lower the cost of personnel expenses including the cleaner cost. (5) The sum of costs assigned in repairment and management increases in proportion to the term of using. The costs assigned in special repairment and management are interacting to each other. (6) To reduce the management cost, we have to cut down the personnel in security guard that occupies one third of total management cost with application to the joint security system and operation of the self-governing guard. Through this process, it will be easy to accomplish the rationalization of contract with an outside order. Because the improvement of management service is not only the responsibility of owner but also the one of dwellers. And it Is imperative to realize the importance of cooperation and trust between the owner and dwellers. And the establishment of effective managing system which has convenience and rationality must be settled without delay.

In construction work, safety accidents often occur in combination with unstable physical and human conditions during preparation and execution of work. In Korea, the accident rate is higher to that of any country in the world. Therefore, it is necessary to take measures by fundamental prescription. In this paper, in the case of construction safety management, we tried to find a reasonable alternative through a questionnaire survey to apply to subcontracting and small-scale construction. In conclusion, workers who are well aware of the task could be able to reduce the accident rate by deploying them as safety management officers after receiving the training.
