Purpose: This study aims to establish detailed spatial planning by identifying the needs for a seclusion module for emergency psychiatric patients. Methods: The necessity of medical space with seclusion function was analyzed from spatial, medical, and social perspectives. The needs for a space capable of performing three medical functions: protection, isolation, and treatment, was analyzed. Among various types of mobile medical facilities, seclusion space was considered suitable for utilizing modular construction methods, as it is the most rational method that can satisfy the environmental level of fixed healthcare facilities' space. Therefore, seclusion modules based on modular construction were planned, consisting of two protective units for stabilizing patients with psychiatric illness, one for treatment unit that can accommodate both internal and external treatment, and another one for an infectious disease isolation unit equipped with negative pressure equipment. Implications: This study analyzed the necessary medical functions of the interior space of the mobile stabilization module based on the spatial analysis of existing medical facilities, and proposed alternative spatial configurations according to treatment, seclusion, isolation functions.

The Multi-family Residential is one of the most famous building types for a rental property in the US. Often times it includes multiple residential buildings and some amenity facilities, including a clubhouse or leasing office, swimming pool, dog park, and garages. Since the building type is built for rental purposes, the construction planning is phased and it makes the project complicated. Detailed planning and execution are important for successful construction management. This paper provides some management practices that are applied to one of the multi-family residential construction projects in Phoenix, AZ. The Front End Planning (FEP) process performed by both owner and contractor is the first key to a successful construction project. Specifically, the early review of phased turnover strategy, grading, fire/Americans with Disabilities Act (ADA) compliance, and Mechanical/ Electricity/Plumbing/Technology (MEPT) will provide absolute benefit to the project. Second, using a scheduling method to control short-term schedules and long-term can provide the ability to manage the issues with agility. Third, material delivery and procurement dominate the both project schedule and cost. With this COVID-19 circumstance, it is hard to expect the material, equipment, and labor forces to be delivered on time with the contracted price. Managing floats are more than important to managing construction productivity. Risk management should work to share the risks fairly. Lastly, turnover is directly linked with the profit of the project for both owner and contractor. The communication between the owner and contractor to re-schedule the proper turnover schedule is important for the phased construction project.

발파공사 현장 주변에는 많은 종류의 보안물건이 존재하고 있어 발파진동의 영향을 저감하기 위해 각 기관별로 발파진동 허용기준을 제시하고 있다. 그러나 현재 적용되고 있는 발파진동 허용기준은 지나치게 강화 적용하여 공사비 증가와 공기 연장의 폐해가 발생하고 있는 실정이다. 본 연구에서는 기존 설계와 시공사례 등을 토대로 적용된 발파진동 허용기준을 검토하고 그 문제점을 분석하여 합리적인 발파진동 허용기준을 산출하는 방법을 제안하고자 한다.

The Korean society, which faces a new issue of foreign labores, is actively conducing safety consciousness of foreign labors. Foreign labors of domestic industry reached about 360,000 recently. it has become the essential resources to fill up insufficient labor in construction industry. Although most foreign labors participate in safety education well and understand its object, some foreign labors have negative recognition of it. Some foreign labors well comprehend the importance of safety facilities but think those unnecessary. Based on these results, this research pointed out the need to review training manuals, the development of educational programs, improvement of educational facilities to improve safety education of construction, and finally to discussed these issues.

Evaluation of construction claims history can provide insights to improvement opportunities in a capital project portfolio. This study analyzed construction litigation claims extracted from the U.S. Court of Federal Claims (COFC) history involving the U.S. Naval Facilities Engineering Command (NAVFAC) from 1995-2004. Twenty-four total cases were examined over this period. Both "primary" causes and "root" causes were identified and compared to 666 litigation cases reviewed by the Armed Services Board of Contract Appeals (ASBCA). Based on the analysis, strategies for resolving future disputes are recommend using a 'hybrid' process prior to litigation.

Although issuing change orders is a common practice in the construction phase of any project, non-structural utility subcontractors are struggling and seek to find a way to reduce change orders. Therefore, this paper presents the analysis results on change orders to cultivate possible suggestions and solutions on how to reduce or minimize change orders in mechanical, electrical, and plumbing (MEP) works. Change orders in non-structural utility works are analyzed based on six categories such as rerouting and change of location, changes in weight, rejected design by Office of Statewide Health Planning and Development, District Structural Engineer, or the Structural Engineer of Record, unforeseen conditions, changed equipment, and owner-initiated change. The analysis findings showed that rerouting and changing location is the most significant cause, followed by unforeseen conditions. The results not only contribute to the existing body of knowledge on change order research area, but also help MEP contractors reduce the time and cost of change orders.

The management of defects in barracks facilities is carried out in such a way that defects found by the facility's manager are listed and requested to be repaired by the contractor. However, the standards and methods for the inspection of defects in the management of these defects are not specified in detail, so it is difficult to check the defects in detail. In response, the study first analyzed the current status of the number of defects that occurred in 2021 at official residences and barracks of certain units. As a result of the analysis, the number of defects that were not taken care of and that were not taken until the previous month was more than 10 cases on average per month. In order to reduce the number of such defects, major improvements in the field, timing, and safety inspection were found after the inspection of the military's facilities and safety, and the analysis of the manual of maintenance management. In addition, items for improvement of the checklist were derived through an analysis of the repair of defects caused by the unit's official residence and a total of 10 barracks facilities. Based on this, a checklist was proposed to manage defects in barracks facilities through interviews with military facility managers.

이 연구는 공사현장 근로자의 임시소방시설에 대한 집단 간의 사전 지식을 비교 문제점을 도출하고 그에 맞는 개선방안을 강구하여 화재사고를 미연에 예방하는데 연구의 목적이 있다. 연구결과는 다음과 같다. 첫째, 소화기의 경우 시공사, 감리원, 협력사 근로자와 소화기 관리책임자를 지정 간 통계적으로 유의하였다. 시공사 공종별로 소화기 관리책임자를 지정이 필요하다고 응답한 소방관리자 87%, 설비감독자 70%로 차이가 있음을 알 수 있었고, 이는 근로자들이 임의로 화기 작업장으로 이동하여 배치하고 작업 후 그냥 방치하는 사례가 많기 때문에 소화기 관리책임자를 지정하고 수시로 점검하고 재배치하는 관리지정이 필요하다. 둘째, 간이소화장치의 경우 시공사, 감리원, 협력사 근로자와 간이소화장치 무단사용 시 벌칙적용 간 통계적으로 유의하였다. 셋째, 비상경보장치의 경우 시공사, 감리원, 협력사 근로자와 임시방송설비로 비상경보음 발생 적용 간 통계적으로 유의하였다. 넷째, 유도등의 경우 시공사, 감리원, 협력사 근로자와 통로유도등 및 비상조명등 연계 적용 간에는 통계적으로 유의하였다. 협력사 공종별로 피난구 유도등과 통로유도등 및 비상조명등 연계 적용은 건축근로자 65%, 전기근로자 55%가 통로유도등 및 비상조명등 연계 적용 차이가 있음을 알 수 있었다. 이는 건축물 구조상 피난구 유도등의 사각지대를 해소하기 위해서 통로유도등 및 비상조명등과 연계 적용하여 출입문의 방향을 먼 거리에서도 쉽게 구별하여 작업자가 인지하여 안전하게 대피하는 장치가 필요하다.

As for the purpose of this study, education facilities must be considered by a change of an education facilities equipment acid education system and aromatic character of an educational policy with a means to support to efficiently proceed education by study about a plan of the school education facilities which considered safety. That is, education facilities must become maintenance on design construction according to education action character and goal. This is not for a function of education to be decided according to education facilities, and education facilities must be decided so that adjustment can do an education function. The student center, a student are convenient, and an actor must do a plan of education facilities with an usable physical space contrariety, future directivity. As for the plan of school education facilities, facilities must be designed on functionality, an economy, flexibility, aesthetic appreciation anger, a foundation of stability for this so that objective of education realization is easy.
