A construction site survey is carried out for the Construction Standard Unit Price(CSUP) in order to establish a standard for the appropriate estimated price. This paper proposed the revised plan by surveying the 56 sites under construction from March to October 2022 for interior finishing work and Carpentry work. It is expected that the revision of the CSUP for interior finishing work and Carpentry work will more accurately reflect the actual construction situation and contribute to improving the adequacy of the CSUP.

Research on construction waste unit was in progress in the 1995 when 'Proper Disposal and Recycling Measures for Construction Waste' was made by the Seoul Development Institute. Such an effort has been made in order to cope with the lack of natural resources in Korea and to utilize the reusable resources. Furthermore, these efforts have also increased due to the improved standing of Korea in the international community. A large number of residential buildings were built in the response to the government's policy by increasing the supply of houses between the 1970's and 1980's. In 2000, more reconstruction and redevelopment was done because of the aged buildings and change of use for those buildings. And the project has been actively promoted until now, which caused a sharp increase in the generation volume of construction waste. In Korea, 8 kinds of construction waste unit, including the standard construction manpower and materials estimation, are introduced. Currently, they provide standards to different building categories and waste properties while for construction sites different standards are applied. This study aims to measure the actual amount of construction waste after sample buildings are dismantled and analyzes the estimation of the waste quantity by using various standard units. Through comparison, this study will figure out the differences among the standard units in order to find out how to apply the standard units properly. Moreover, this research will provide practical measures to apply such units to construction sites.

This paper develops a standard time table using STD(Standard Tine Data) Technique in multi-product and one-unit production systems. STD leads to greater consistency between similar jobs. The constant-time and special elements will always be the same even though they pertain to different part numbers. Actually, the standards will very based on the size of the variable elements that are in control of the time. A real-field example is presented.

Unlike price calculation by cost accounting, which categorizes costs into material costs, labor costs, and miscellaneous expenses to determine the construction budget price, construction cost calculation based on Construction Standard Unit Prices utilizes unit prices extracted from market prices of items from projects already completed to estimate costs of similar construction projects. Although unit price information is collected through construction site surveys to revise these construction standard unit prices every year, but due to the limitations of the site survey method, it is difficult to quickly implement the rapid changes in the construction methods and market prices. As such, an important issue that arose was the identification of work items whose prices need urgent revision. This study conducted research on factors that need to be considered when developing online survey system for monitoring construction site market prices. This study is expected to enhance convenience for users, and provide an efficient data collection and management system for administrators.

The purpose of this study was to investigate unit care characteristics of large skilled nursing facilities for the elderly, which are located in city areas, and to discuss the way of encouraging home-like atmosphere in perspective of spatial unit. First of all, the analysis of five facilities opened before 2002 was performed, based on previous studies, to compare with them opened in recent 5 years. Most of the previous facilities did not have differentiation between their residential and nursing units, and the number of residents in each unit were excessive in comparison with the standard limit(12-28). On the contrary, the facilities established in recent 5 years had systematic spatial unit structure. The residential units had basically rooms and spaces for small group and the number of elderly residents per unit was appropriate on the basis of standard limit which was suggested by Kwon(2002). The nursing units were consist of nursing station, 2-3 residential units, spaces for large group of residents, hair dressing, nurse, living assistant, bathing, storage and etc. But, there was a problem In space usage even though they have distinct unit care systems. Some spaces for groups were empty without residents, furniture, and other equipments, which were necessary for unit care.

실적공사비 적산방식은 품셈견적, 실측견적, 단가견적, 및 총액견적 등 매우 다양하다. 표준품셈은 공공기관 및 민간기관의 공사비 책정기준이 되는 자료이다. 본 논문에서는 도로공사에 이용되는 기존 품셈견적의 문제점을 개선하기 위해 현장조사를 실시하고 분석하였으며 그 결과로 각 공종에 대한 실측견적 방법을 통계적 방법을 통해 제시하였다. 또한, 기존 품셈과 실측품셈을 공사단위의 비교를 통해 제안된 품셈이 보다 간단한 견적 작성을 가능하게 하고 보다 현실적인 공사금액을 산출함을 알 수 있었다. 본 연구에서는 보조기층의 Case-Study를 통하여 각 방식별 장단점을 가시적으로 비교해 보았다. 실측품셈으로 적용하였을 경우, 계산과정은 기존품셈의 50%로 축소되었으며 1일 1장비 사용으로 기존의 1일미만 장비 사용에 대한 편차가 보완되었다. 또한 품셈만을 이용하여 공정의 시공내용을 짐작하고 이를 바탕으로 공정계획이나 인력투입계획 등을 수립할 수 있었다.

The WiBro was adopted to the 3G international standard. By the change of specification from Wave 1 to Wave 2, MIMO technology is applied in order to increase the speed of downlink. By MIMO the RF part of WiBro base station is increased to 2 Tx paths. Therefore, the size of RF part is bigger and material cost is increased. For reducing these demerits, the RF part which is consisted of PA, LNA, and TDD switch is designed to one complex RF unit. Also, the experimental results of the RF unit have been discussed. Since the complex RF unit is more compact than the RF part of Wave 1 base station, it can be used as the RF part of Wave 2 base station with 2T/2R MIMO.

조경공사 표준품셈은 표준적이고 보편적인 공종과 공법들로 구성되어 있다. 그러나 최근 조경분야는 건설기술의 발전과 공사품질의 고급화가 요구되고 있는 실정이다. 그러나 현행 조경공사 표준품셈으로는 이러한 변화에 대응하기에는 한계가 있다. 이에 본 연구는 조경공사 표준품셈의 발전방안을 제시하는 것이 중요하다고 판단하여 우선 개정들이 필요한 품셈 공종을 파악하였다. 개정이 필요한 공종을 파악하기 위하여 문헌고찰과 예비설문조사를 통하여 설문 항목을 선정하였으며, 선정된 항목들은 조경 분야 전문가 60명으로부터 응답을 받아 통계처리 하였다. 연구의 결과는 다음과 같다. 첫째, 조경공사 표준품셈에 대한 활용도는 식재공종의 품셈이 가장 높았다. 둘째, 신규로 추가될 필요가 있는 공종으로는 정지공사, 조경 구조물공사, 포장공사, 수경시설공사, 옥외 시설물공사들로 파악되었다. 셋째, 조경공사 품셈공종 분야에서는 설문응답자들의 66.7%가 개정이 필요하다고 응답하였고, 개정이 필요한 품셈 공종으로는 식재 공종에서는 대형수목, 조형수목, 수목가식, 수목하자 등으로 파악되었다. 굴취공종에서는 대형수목, 조형수목 등으로 파악되었다. 유지관리공종에서는 전정폐기물 처리 품셈, 정원석 쌓기 및 놓기 공종에서는 돌틈 식재 품셈, 떼붙임 및 초류파종 공종에서는 현실적인 잔디규격의 품셈을 필요로 한다고 응답하였다. 연구의 결과들을 바탕으로 조경공사 표준품셈의 발전방안을 제시하면, 조경 식물의 규격과 조경공사 품질에 대한 공종별 세부 품셈과 조경공사 품질에 영향을 미치는 품셈분야의 개정이 필요하다.

It is needed to classify the kinds of construction and demolition(c&d) debris to 6 catagories of waste concrete, waste asphalt concrete, waste wood, scraps, combustible waste and incombustible waste in order to properly do a separate discharge and to estimate unit generation rate in construction site. Also, in this case, the unit treating cost for mixed wastes should be applied with the unit treating cost for combustible waste. The construction standard materials estimation data is used for basic data for estimating unit generation rate. The mixed wastes in this data should be classified to waste wood, combustible waste and incombustible waste, and their ratio is obtained by using the unit generation rate of Asia Pacific Environment and Management Institute and Seoul Metropolitan Development Institute. The waste amounts generated from newly-built construction can be obtained from multiplying the loss rate by the amount of materials used from construction standard estimation data. Also, those from dismantling construction can be obtained by subtracting waste amount generated during newly-built construction from total input amount of materials in newly-built construction. Those in two cases can be used in construction site. It can be used for estimating the amount generated and establishing the treating plan in the case of setting up the policy of waste management and doing the environment impact assessment.
