체계화된 전기공사의 내역서 작성은 공사의 품질관리 및 공정관리를 원활하게 할 수 있는 기본이 된다. 공사의 혼란을 초래하지 않으며 업무의 효율화를 기할 수 있는 일목요연한 내역서 작성이 필요하다. 따라서 본 연구에서는 우선 내역서 자체가 가지고 있는 문제점을 해결하는데 중점을 두고자 한다. 즉 현행 내역서 문제점인 단위공종 및 규격의 표준을 제시 및 용어통일을 기하고자 하며, 주요 발주기관에서 운용하는 내역특성, 발주특성을 조사후 장단점을 파악하여 향후 내역서 간소화 및 단순화 작성의 기초적인 데이터를 확보하고자 한다.

Recently, BIM has been actively introduced in construction projects. In particular, the introduction of BIM in cost estimating process is expected to improve the accuracy and efficiency of the cost estimate. However, the quantity calculation and BoQ documents preparation process still require manual work. Although the BIM model may support quantification process, it is still problematic that the level of detail of the model must be very detailed to meet the items in BoQ. To address this, it is necessary to analyse the LOD criteria and to analyze the extent to which quantity can be computed according to the level of detail in the BIM model. For the analysis of LOD-based work items, the work item grades were divided into A,B, and C. In this study, the ratio and cost of each item that can be calculated at the LOD level in the detailed design phase are reviewed for each type of work, and the method for improving the quantity calculation using BIM is proposed. In the LOD 300 stage(Detailed design stage), the largest number of items in the class B, the major improvement class, are window and glass work. In addition, the most expensive type of work was analyzed by reinforced concrete work. In the future, it is necessary to suggest appropriate improvement way for items with high item ratios and items with high cost ratios. The results of this study are expected to be used as a BIM-based cost estimation or as basic data for improving the current BoQ system.

Construction work is an art of making something out of nothing. To run the construction project smoothly, budget, organization and engineering should be balanced. Standardization and simplification of construction bill are needed in order to maximize the

내역입찰제도 개선, 적격심사항목 보완, 적격심사 이행관리계획 미준수 업체 제재사유 추가, 정정공고 근거규정 마련 등을 주요 골자로 하는 국가계약법 시행령 및 시행규칙이 제.개정되어 지난 10월 10부터 시행에 들어갔다. 개정된 시행규칙은 1억원 미만 소규모 공사는 물량내역서가 계약서에 포함되지 않아 발주기관의 물량산정 오류시 설계변경이 불가능해 소규모 공사에서 경제적 피해가 많이 발생되어 민원이 제기됨에 따라 우리협회는 재정경제부에 "1억원 미만 소규모 공사도 계약서에 물량내역서가 포함되도록" 건의한 결과 우리협회의 의견이 반영되었다.

Currently, the unit price of public construction projects are not being evaluated appropriately for several reasons. First, the evaluation of the unit price differ per nature of the bidding process and its estimation process. In fact, pricing is determined to meet the total price in turnkey projects and to pass the low bid price deliberation process in unit price projects, and thus, such prices cannot be said to be reasonable prices per public project. After the contract is awarded, however, the prices determined without taking into consideration the characteristic of each bidding process and price estimate process are used for the valuation of progress payment, design changes, and escalation. Furthermore, this is also being applied to other low bid deliberation process as actual public project unit price, thereby affecting other processes as well. In effect, this system increases the risks for both the owner and the bidder who have determined the unit price. This research examines the risk factor and its extent in order to properly manage it in preparation for the future.

Modular construction is one of the arising issues in the Korean construction industry due to shorter construction period and higher productivity on site. It is also expected that modular construction market would expand rapidly because of increasing demand of small houses by nuclear families and eco-friendly construction. However modular construction cases have been limited in Korea because of little demand in the market and the construction prices are even higher that the regular reinforced concrete methods. Even worse, because there is no standard bill of services exists in the industry, it may lead to the risk of construction expenses. So, the purpose of this study is focused on the development of bill of services which reflects characteristics and process of modular construction. In order to do this, the concepts and process of modular construction, WBS and CBS are analyzed. Analyses of the case studies and experts interview were executed so that proper principles for organizing bill of service of modular construction is established. Finally according to the 3 steps of modular construction, factory manufacturing, on-site modular construction and on-site general construction, the standard bill of services were suggested with the related coding system.

In construction management, BoQ(Bill of Quantities) has been commonly used for the cost estimation. However, many problems have been recognized about the work items used in the BoQ that could be varied by the experience and knowledge of the estimators or the project. Also, there are lots of work items that have to be written in BoQ even though the cost proportion of those items is relatively lower than the others. In this study we consider the way how to organize optimally the work items through the analysis of case. The results of this study could be useful for improving the efficiency of preparing construction BoQ and conducting Quantity take-off in our construction management practices.

The purpose of this study is to develop framing principles for the standard form of the apartment management expenses levy. The researcher with apartment managers and executive secretaries of Busan Citizen's Coalition for Economic Justice made framing principles for standardization through discussion of 5 times as well as investigation of several lists for the apartment management expenses levy. These framing rules are as follows. First, to arrange the expenses and amounts used. Second, to standardize items of expenditure. Third, to present basic contents of apartment such as the characteristics, the amounts of bank deposits, extra incomings and outgoings, and all-inclusive table of apartment management expenses. Fourth, to show the obvious explanation of items.
