In this study, The matrix method was used with common category concept according to the construction project control system. For the purpose of systematic resource management planning, it should be established on accomplished EVM data for clearing the ordering point according to the attribute procurement analysis. Resource management was presented by connecting the material requirement calculation method and the attribute of procurement method based on the EVM, suggested through analyzing process-data modeling using integrated schedule, cost and material.

소프트웨어 개발 프로젝트 초기단계에 수립한 일정 및 비용 등의 계획은 수행 중 발생하는 많은 불확실성을 반영하고 있지 않기 때문에 진행되고 있는 프로젝트는 초기에 계획한 일정과 비용에 많은 차이를 보이는 경우가 발생한다. 이에 따라 본 연구에서는 진행 중인 소프트웨어 개발 프로젝트의 상황을 분석하고 예측할 수 있는 방법으로 일정과 비용을 통합 관리할 수 있는 획득가치관리(EVM: Earned Value Management)를 활용하는 방안을 제시하였다. 획득가치관리(EVM)을 적용하기 위해 일정과 비용의 통합관리하기 위해 예상되는 투입 인력과 비용 등을 감안하여 작업분할 구조(WBS)와 연계하여 계획을 수립하고 측정하는 방법을 구축 중인 프로젝트의 사례를 통하여 적용 방안을 제시하였다. 사례 분석한 각각의 프로젝트 진행 단계에 따라 예측한 값이 실제 계획 대비 일정과 비용에 대한 예측 오차 변화 추이를 분석하였으며, 향후 진행되는 프로젝트의 일정 및 비용 등의 계획을 체계적으로 수립하고, 진행되는 프로젝트의 일정 및 비용 등에 대해 분석하고 예측하는데 활용할 수 있도록 연구하였다.

In domestic construction industry, time and cost has been managed separately in most cases. Usually projects are managed focused on cost, so time is not yet managed systematically. Project performance in these managemental situation can not be assessed correctly. This would cause project delay, cost overrun, productivity loss. Therefore it is needed to adopt earned value concept, an approach used in the management and control of project costs and schedules. Using this EV concept through time-cost integration, project can be managed properly based on the consistency, predictability, and reliability of the performance data. This paper proposed time and cost integration process, proper PMT method, and practical performance management model through time and cost integration.

The systematic material and labor management planning should be established on accomplished EVM data. The matrix method of integrated cost and schedule was used with common category concept according to the construction project control system. The construction project control system was suggested through analyzing process and data modeling based on integrated cost, schedule and material. Information of construction project can be developed the relationship between the field data and the integrated cost, schedule database. Process and data modelling is provide a standard data format which are related to the material, labor management based on integrated cost, schedule database.

Recently construction projects become more bigger. So construction companies have being performed cost and schedule management task by using PMIS. In engineering and construction phase, progress management which occur the most frequent information I/O(input and output) should be managed effectively by PMIS. Although most information by PMIS manage efficiently, cost-schedule information for progress management is difficult to be managed due to recurrent information input. thus when changed by price fluctuation and change order, progress management could not connnect cost information with schedule information. So it caused inaccuracy of progress measurement and data increase in PMIS. To solve this problem, This study suggests improved module for progress management through integration of cost-schedule using quantity take-offs as progress measurement method.

우리는 국가 경쟁력의 한 분야인 사업관리에 있어 계획, 수행, 성과관리, 개선에 최적의 프로세스 보유가 요구된다. 그러나 Project관리체계의 현 실태는 일정관리, 범위관리, 비용관리에 초점을 맞춘 일정관리체계, WBS(Work Breakdown Structure) 및 OBS(Organizational Breakdown Structure)관리, 비용관리체계의 부분 통합 혹은 서로의 연계 정도이다. 본 연구는 최적의 사업관리를 위하여 계약관리에 체계공학을 연계하여 계약 전에 WBS, IMP/IMS(Integrated Master Plan)/(Integratcd Master Schedule), TPM(Technical Performance Measurement) 등의 SEP(Systems Engineering Plan)와 계약 후의 이행을 검증 할 수 있는 과정의 Guideline을 제시하고, IEEE 1220, ANSI/EIA 632 순기 의거 개념설계부터 통합시험에 이르는 체계공학 순기에 따른 비용예측이 가능한 USC(University of Southern CalIfornia) 대학의 COSYSMO (Constructive Systems Engineering Cost ModeI)를 소개하고 적용 가능성을 고찰하며, Project의 전순기에 걸쳐 TPM 혹은 Quality를 비용과 일정에 통합하여 관리하는 PBEV(Performance Based Earned Value)모델을 소개하고 적용 가능성을 제시한다. Project 관리에 있어 System 차원을 강조한 SE(Systems Engineering), 비용예측의 CM(Cost Management), 성과관리를 위한 EVM(Earned Value Management)의 통합은 사업 관리에 역량을 강화하며 경쟁력을 향상 시킬 수 있는 적절한 접근으로 사료된다.

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.

In construction projects, it is very important to evaluate the performance of works in comparison with the cost and schedule plans. So, on the first of July, 2000, the Ministry of Construction and Transportation announced the EVMS will be applied in public sector soon. However there are still many arguments about how to establish the Performance Measurement Baseline(PMB) and how to evaluate the progress with accuracy. And many people confuse the meaning of EVMS with that of cost and schedule management. So, the purpose of this research is to propose the new useful methods to set up the PMB and to assess the exact progress in consideration of cost, schedule, and float time for successful implementation of EVMS.

Connecting with cost, schedule, and quality in a construction project, resource management is one of the essential management elements. However, the material requirement planning is built at the beginning stage of construction and needs various concerned factors, it is limited to build the resource management planning on enterprise level. The disconnected communication among managements makes impossible to control historical data. In the construction project control system, the core of management elements is to manage cost and schedule information, therefore material requirement planning should be established based on historical data about EVM which is intergating schedule and cost. In this study, a resource management system concerning material requirement planning and attribute of procurement is suggested by connecting the historical data of EVM and the material requirement planning.
