The time and cost is the most important information for the construction project management. Currently, a lot of studies have been done in order to clearly relate them with each other, but there have been some difficulties. Because of the characteristic of Korean government contract law, the construction project in Korea is managed by only cost and the time and cost information is distinctly separated. In order to manage all the major construction project information smoothly, the time and cost information should have relation with each other. This study suggest methods for relating the time and cost information, especially for road construction project of MOCT. Through the survey of construction field engineers and case study of the road construction project, several alternatives to improve the usability of construction information are suggested in this study. These alternatives can support relating other construction information.

공사비정보와 일정정보는 사업을 관리하는데 있어 매우 중요한 정보로 이들이 연계활용되어야 공정공사비 관리를 원활하게 진행할 수 있다. 그러나 국내의 실정은 공사비가 내역체계 기반으로 관리됨에 따라 설계사에서 작성되어 시설, 부위, 공간 등의 정보를 갖고 있던 수량정보가 내역체계 기반으로 전환되면서 정보들을 상실하고 시공사에서는 다시 물량분개라는 작업을 통해 다시 시설, 부위, 공간 등의 정보를 부여하는 작업이 발생하고 있다. 이에 도로분야 사업을 대상으로 작업분류체계(WBS)를 그 연계방안으로 제시하고 작업분류체계 기반 공사비 작성을 통해 설계사에서 작성된 정보를 시공사에서까지 활용할 수 있도록 하고자 한다. 본 사업에서는 이러한 작업분류체계 공사비 작성을 위한 지원도구 개발을 위해 업무 프로세스 검토, 지원도구 활용 공사비 작성, 시험적용을 통한 지원도구 검증을 수행할 계획이다. 이를 통해 내역정보와 공정정보의 연계가 실현되고, 효율적인 공사비 관리의 기반을 제공할 수 있다.

3D and BIM technology are presumed to be used more and more in the construction industry. The scope of this paper arose from a general wondering of how the constructor in general can benefit from the use of 3D models. Presented herewith is the first application of BIM in Korea to a actual bridge construction site located in Cheongpoong in Chooncheongbook-Do. This paper tries to integrate design, cost and schedule under location-based conditions with industry-specific solution for 3D modeling. 292 activities constitute the cable-stayed bridge of 442m long with a main span of 327m long. Integration of 3D model, cost and schedule is shown by comparing the measurements of works at a specific time by use of 2 different construction sequencing scenarios and cost breakdown structures.

The major objective of construction process control(CPC) is to provide construction managers with operational information that will help reduce project duration and save project cost. However, the CPC in Korea is being applied to construction projects with some basic problems such as the inconvenience of CPC S/Ws and the process control unconcerned with construction information classification system and computer system to integrate cost and schedule. This study analyzes the present condition of CPC including the basic problems, and then suggests the reform measures in technical and operational viewpoints to reduce construction risk. The focus of study is on the technical improvement for the application of construction information management system applicable to both cost estimating and schedule management.

As the government has enforced recently the policies on the distribution of the housing, the construction cost of multi-family housing projects has increasingly become very sensitive and political issue. However, it is difficult to predict the construction cost in planning and design phase of the project because the Bill of Quantity of the multi-family housing projects was composed of breakdown structure based on each work package. To predict the construction cost in planning and design phase for multi-family housing projects in more effective and reasonable way, this study developed the cost breakdown structure based on spaces using Delphi method. The Cost Breakdown Structure (CBS) based on spaces for multi-family housing projects basically consists of three parts: (i) Building part; (ii) Non-building part; and (iii) Additional part. The characteristics of spaces in multi-family housing projects are fully taken into consideration. Then these three parts were subdivided into work packages in terms of work tasks. Additionally, the usefulness and effectiveness of Space CBS in this paper were validated by analyzing the BOQs of several collected sample projects and matching with Space CBS afterwards.

The government abolished the existing method to calculate the construction price by the quantity take-off and pricing. It has introduced a new estimating system which uses the actual cost data on the basis of actual contract unit price. However, in the case of the current method to calculate the estimate price of BTL educational facilities, it is difficult to prepare an accurate ground for calculating unit prices due to a lack of standardized work breakdown structure (WBS) and guidelines for the detailed bidding documents. Thus, this research aims to establish WBS using the actual construction price on the basis of the actual bidding documents for the previous construction of BTL educational facilities. This specific WBS can be differentiated from the general WBS which is not suited for construction of the educational facility. It makes possible to build the construction information classification system and it helps to systemize the maintenance and repair cost items.

One of the crucial components in building information modeling (BIM) is data. To systematically manage these data, various research studies have focused on the creation of object breakdown structures and property sets. Specifically, crucial data for managing programs and payments involves work breakdown structures (WBSs) and cost breakdown structures (CBSs), which are indispensable for mapping BIM objects. Achieving this requires disassembling CBS quantities based on 3D objects and WBS. However, this task is highly tedious owing to the large volume of CBS and divergent coding practices employed by different organizations. Manual processes, such as those based on Excel, become nearly impossible for such extensive tasks. In response to the challenge of computing quantities that are difficult to derive from BIM objects, this study presents methods for disassembling length-based quantities, incorporating significant portions of the bill of quantities (BOQs). The proposed approach recommends suitable CBS by leveraging the accumulated history of WBS-CBS mapping databases. Additionally, it establishes a unified CBS code, facilitating the effective operation of CBS databases.
