In relation to the latest induction of construction management of the government, there are many problems that need to be decided beforehand. First of all, the powerful regulations of construction-related laws in which various circumstances are involved, because obstacles to the induction of C.M. system is run with self-control. Also, a situation that causes problems for the inefficient operation of supervision system which has the function similar to a C.M. system in korea, produce main obstacles to the induction of C.M. system. In this case, a research questionnaire survey for construction-related company is performed. So ① problems for a current construction company and current supervision company are analyzed. ② The subject which precedes when C.M. is inducted and the improvement plan of construction-related system for the conversion of supervision into construction management are proposed.
확률적 건설공사 비용분석에 의한 위험도 평가방법의 이론적 연구
전재열,조재호 단국대학교 2000 論文集 Vol.35 No.-
The paper considers two non-deterministic methods of analysing the risk exposure in a cost estimate. The fist method(referred to as the 'conventional ststistical' method) analyses cost data directly, to describe a probability distribution for total cost. The second method(reffered to as the 'Monte Calo simulation' method) interprets cost data directly, to generate a probability distribution for total costs from the descriptions of elemental cost distribution. The common practice of allowing for risk through an all-embracing contingency sum or percentage addition is challenged. Rather than excluding conventional, nondeterministic methods, they are here presented as possibly the only effective foundation on which to risk management in cost estimating.

The purpose of this paper is to develop the running cost decision model for the office buildings which can forecast the running cost with the cost-related factors in the planning stage. The influences of design on running cost is understood and estimated in figures in the early stage of planning and designing of architecture. So it makes an alternative choice of architecture possible. Statistically extracting the cost information and the decision factors for running cost model, the multiple regression analysis followed in order to obtain the regression curves for running cost. As a result of the correlation analysis shape & total floor area etc, factors were identified as the main factors in office building and the difference ratios between factors are from 1.15 to 1.5.

A new act as an important law, titled "Consolidation Act for Urban and Residential environment" compromised "Professional Consolidation Project Management system" was promulgated by Ministry of Construction and Transportation, entered effective as of July 1, 2003. This system which is improving and leveling-up previous consulting process implements the essential Tasks for housing complex of reconstruction/redevelopment through the processes and procedures. Tasks from them need to be added the construction management tasks on the reasonable, logical, systematic tool. Depending upon joining the Professional Consolidation Project Management, CM will deliver a lot of benefits, greater than to an housing association, to structured many inhabitants in the project.

The purpose of this research is make out construction specifications for International Construction. Using off-shore products incur cost increase and longer delivery term of construction. and inconvenient on International Construction. Expand the range of additional local products conforming to performance. Life Cycle Cost. maintainability. operability. user's acceptability, etc.. And this study is suggest the standard formats and the techniques for construction specification.

Recently, the temporary facility site-layout planning in high-rise building construction, was made by expert's experience and intuition and controlled by mistake of enforcement. It was caused of exceed cost and delayed schedule. And the knowledge and information that was gained from performances temporary facility site-layout planning was not practical used to next planning, that is why similar problems were occurred in the project of similar condition. The purpose of this study is development of knowledge-based database for supporting of decision making in temporary facility site-layout process. Therefore, in this study, the process and influence factors for temporary facility site-layout were analyzed. And the method of knowledge making and accumulation were proposed by application of the three-dimension matrix concept.

Recently, various problems have been occurred in Apartment reconstruction process. Such as, delaying schedule, additional cost increasing, etc. Those were caused by decision making which is lack of professionality in early phase of reconstruction process. Therefore, in this study proposed improvement plan by application of project management and construction management process in Apartment reconstruction project.

Recently, the importance of cost control is increasing in the early design phase. But there is little information that can be used in the early design phase. and cost data of work item is difficult to recognize cost changes by functional alternative change in the design phase. It is necessary to constitute historical element cost data for the effective cost plan and control in the early design phase. Therefore, the purpose of this study is to present the plan of elemental cost data generation and database constitution.

In Korea construction project case, architectural construction project is curtailed production because information network process within multidisciplinary isn't smooth. Particularly, the construction is not insufficient about performance, cost and material, construction process, etc. in result various question arises because of design error in construction step. And various mistake is made because communication path within multidisciplinary isn't smooth in architectural design and design change process. Therefore The final object of this study is to propose the establishment method of decision support model for the cooperative design in order to provides improved design coordination and optimize the building system.

To predict accurately an antenna radiation pattern is very important for determining of a service area, base-station location, cell design. In this paper, we have calculated a propagation prediction data of Hata, Egri, Carey, Free Space Loss model by a computer simulation in Kwang-ju downtown, and the data is compared with field test data. As a results, Hata and Egri model are approached to field test data, but considerable errors are detected.Conclusively, we believe that the most accurate prediction model must propose to improve the radio propagation environments for the specified region. For resolve these problems, we are proposed a mew experimental radio wave propagation predict model.
