Network Compression by Saying Idle Time of Resources and Spaces for Repetitive Activities
Yi Kyoo Jin ;
Korean Journal of Construction Engineering and Management, volume 1, issue 3, 2000, Pages 75~80
In scheduling multi-unit projects, several alternatives can exist in network construction due to repetitiveness of their activities. Project duration is affected not only by the duration of each activity but also by the arrangement of repeating activities in such projects. This paper provides a network compression method that assigns predecessors to each activity to minimize its float time. Different to the previous efforts that utilized line of balance as the base scheduling-model, this research adopts precedence diagram arranged in two coordinates, the space axis and the resource one. This method seeks the most appropriate predecessors for each activity in each direction of the two coordinates for the purpose of minimizing the idle resource and space. This activity arrangement method was applied to a multi-unit apartment-construction project, to prove its capability of network compression. The result shows that the method successfully sought room for saving construction duration by changing the activity arrangement. The network compression method presented in this research can be utilized in multi-unit construction projects such as apartment complex projects.

Recently the Government has classified the construction specifications into three types such as national standard specifications, owner's standard specifications and project specifications, by the revision of the Law of Construction Technology Management. And the Government provided that project owner shall use the project specifications that are written by excerption from, revision of, and supplement to the national standard specifications or the owner's standard specitications etc.. The present study suggests the writing way of national standard specifications, owner's standard specifications and project specifications in these situations.

The purpose of this study is to maximize project efficiencies in construction management by analyzing hierarchical factors that effect in project supervision system, and consequently constructing managerial CSF(Critical Success Factors). For this study, the tools for evaluating operating and management abilities of site engineers are built from analyzing status and issues, deducing influence factors and rating cardinal scales of these factors from survey results. These evaluation tools are reflected to the construction supervision decision making process so that can improve project management effectiveness.
A Study of the Best Performance Index for Estimate at Completion Forecasting Model on the Earned Value Management System(EVMS)

On 1 July, 2000, the Ministry of Construction and Transportation announced the Earned Value Management System(EVMS) will be applied in public sector soon. However the arguments over the EVMS applied to our unique construction environment still exist and create strong concerns and worries among some experts it would be another mistakes proposed by the government. We do know the EVMS comes from C/SCSC which was first released by the United States Department of Defense in December 1967, and proved very powerful and efficient project management tool from a lot of practices. Although it is an excellent tool, we can not ignore our many experienced failures appling foreign system due to the differences of construction culture and law between the Korean and US construction industries. The purpose of the EVMS's success in Korea, therefore, this paper tests and proves the EVMS's adaptability and credibility to our construction environment by EAC model, that is one of the most important functions in the EVMS, using very scare EV data of the Korean construction projects.

The average height of buildings in most cities is increasing in an effort to more effectively use land. In addition, as construction technology develops, rapid construction methods have been pursued. However, while there have been great strides in construction technology, the development of a temporary structure that can support the high-rise building under construction and the rapid construction methods has been relatively limited. If the temporary structure is not built on an outer wall of a building being constructed, a worker may be injured or killed in a fall and building materials such as blocks and other objects may fall to the ground, causing the build-up of trash around the building and possible injuries to persons in proximity to the building. This paper proposes a Self Climbing Safety Fence for construction building(SCfence). SCfence was developed to solve the above problems, a tent has been setup to cover the outer wall of the building, or a falling preventing net has been pitched in a direction perpendicular to the outer wall of the building. A case study was performed to verify the validity of SCfence through comparing the safety and cost experience between SCfence and the existing method.

SOC projects entail inherently large-scale works, and need much capital and time. Because of these features, the design activities in SOC projects are performed through a complicated process involving many organizations. A great deal of information is generated and vanished during the process, and the communication among the related organizations plays a very important role in successful fulfillment of SOC projects. But, because the method of information communication has not yet systematically established, there are many difficulties in sharing information. This study aims at establishing the design interface management model which enables the participants to effectively share the information during the design phase. The contents of the study include (1) Restructuring performance organization, (2) A decision making method in collaborative design through partnering with experts, (3) A method to develop Open Design Information Integrated model using Standardization(ODIIS).

In construction projects, the design information, which should contain accurate product information in a systematic way, needs to be applicable through the life-cycle of projects. However, paper-based 2D drawings and relevant documents has difficulties in communicating and sharing the owner's and architect's intention and requirement effectively and building a corporate knowledge base through on-going projects due to Tack of interoperability between specific task or function-oriented software and handling massive information. Meanwhile, computer and information technologies are being developed so rapidly that the practitioners are even hard to adapt them into the industry efficiently. 3D modeling capabilities in CAD systems are enormously developed and enables users to associate 3D models with other relevant information. However, this still requires a great deal of efforts and costs to have all the design information represented in CAD system, and the sophisticated system is difficult to manage. This research focuses on the transition period from 2D-based design Information management to 3D-based, which means co-existence of 2D and 3D-based management. This research proposes a model of a compound system of 2D and 3D-based CAD system which presents the general design information using 3D model integrating with 2D CAD drawings for detailed design information. This research developed an integrated information management system for design and specification by associating 2D drawings and 3D models, where 2D drawings represents detailed design and parts that are hard to express in 3D objects. To do this, related management processes was analyzed to build an information model which in turn became the basis of the integrated information management system.
