The recent paradigm shift in the construction industry has led to a growing demand for industrial construction. In particular, interest in modular housing, one of the areas of industrialization architecture, is soaring. Modular housing is a construction method for completing a building by transporting factory-built modules to the site and assembling them. However, modular housing in Korea has various problems such as errors in design books, lack of factory drawings, and lack of on-site construction plans. BIM is a tool for accumulating, producing and managing various information through 3D models and is a solution to solve various problems of modular housing. In this study, problems of modular housing and BIM utilization of modular housing were presented as ways to ensure the quality of modular housing. Therefore, this study analyzed the problems that are occurring in the construction process of modular housing. And, to address the problem of modular housing, BIM utilization measures were proposed for each modular process step. However, the application of BIM in domestic modular project is currently being carried out in pilot research project. Because of this, the BIM utilize method for modular housing is limited based on the BIM use for general projects and the examples for some modular pilot projects.

A paradigm shift in teaching modular construction in higher education and K-12 is proposed as a means to increase the future adoption of the modular construction technique. To this effect, a new education module is presented to STEM educators. This education module is based on LEGOs and directed towards educators in the architecture, engineering, and construction (AEC) industry. The main objectives of the education module are to increase interest and knowledge of modular construction, acknowledge the benefits of using 3D design with 4D scheduling, and create a simulating hands-on educational opportunity. The education module is designed to allow participants to experience a hands-on simulation of modular construction and stick-built construction through building a LEGO project. Participants are challenged to find the advantages and disadvantages in both construction systems first-hand and record their findings. Results are presented from the preliminary testing of this education model on a group of construction management students at the University of Nevada, Las Vegas. Overall, the survey results showed that the LEGO education module was successful at achieving the project's three main objectives: 1) increasing the participants' interest and knowledge of modular construction through an interactive project; 2) increasing the participants' understanding of the benefits of 3D design with 4D scheduling over the use of 2D drawings; and 3) creating a simulating hands-on educational opportunity to help participants compare modular construction to stick-built construction. In the end, this proposed a new LEGO education module addressing the problems identified from this study with more participants.

Design of a high-speed railway line requires collaboration of heterogeneous application systems and of engineers with different background. Object-based 3D models with metadata can be a shared information model for the effective collaborative design. In this paper, railway infrastructure information model is proposed to enable integrated and inter-operable works throughout the life-cycle of the railway infrastructures, from planning to maintenance. In order to develop the model, object-based 3-D models were built for a 10km railway among Korea high-speed railway lines. The model has basically three information layers for designers, contractors and an owner, respectively. Prestressed concrete box-girders are the most common superstructure of bridges. The design information layer has metadata on requirements, design codes, geometry, analysis and so on. The construction layer has data on drawings, real data for material and products, schedules and so on. The maintenance layer for the owner has the final geometry, material data, products and their suppliers and so on. These information has its own data architecture which is derived from similar concept of product breakdown structure(PBS) and work breakdown structure(WBS). The constructed RIIM for the infrastructures of the high-speed railway was successfully applied to various areas such as design check, structural analysis, automated estimation, construction simulation, virtual viewing, and digital mock-up. The integrated information model can realize virtual construction system for railway lines and dramatically increase the productivity of the whole engineering process.

An important historical monument of Cyprus is an aqueduct that was built in 1747 to provide water to the city of Larnaca and to its port. Because of its importance to the cultural heritage of Cyprus, the aqueduct has been selected as one of the case-study monuments in the project Wide-Range Non-Intrusive devices toward Conservation of Historical Monuments in the Mediterranean Area (WIND-CHIME). Detailed drawings of the aqueduct obtained from the Department of Antiquities of Cyprus have been used for the development of a computational model. The model was fine-tuned through the measurement of the dynamic characteristics of the aqueduct using forced and ambient vibrations. It should be noted that measurement of the dynamic characteristics of the structure were performed twice in a period of three years (June of 2004 and May of 2007). Significant differences were noted and they are attributed to soil structure interaction effects due to seasonal variations of the water-level in a nearby salt-lake. The system identification results for both cases are presented here. This monument was used to test the effectiveness of shape memory alloy (SMA) pre-stressed devices, which were developed during the course of the project, in protecting it without spoiling its monumental value.

This study does try to proceed on the assumption that complex buildings can vitalize urban life of modern society from contemporary complexity and cases of past failure, and intend to propose future planning guidelines and directions of the neighborhood mixed-use buildings in the housing development district of small cities. For this purpose, thirty buildings which had been built on Bugok housing district in Gimcheon from 1999 until 2007 were chosen and investigated in urban and architectural dimension. The scope of this investigation is that site size is below 400 square meter and the number of stories on the ground below 5 floor, and the method of that is through field investigation, field photographs, and recordings and drawings on those. Investigative contents could be divided and analysized into physical and functional elements in urban and architectural dimension. On the basis of these results, the future planning approach of complex buildings in medium and small cities will be considered as planning principles.

The Ting Kau Bridge in Hong Kong is a cable-stayed bridge comprising two main spans and two side spans. The bridge deck is supported by three towers, an end pier and an abutment. Each of the three towers consists of a single reinforced concrete mast strengthened by transverse cables and struts. The bridge deck is supported by four inclined planes of cables emanating from anchorages at the tower tops. In view of the heavy traffic on the bridge, and threats from typhoons and earthquakes originated in areas nearby, the dynamic behaviour of long-span cable-supported bridges in the region is always an important consideration in their design. Baseline finite element models of various levels of sophistication have been built not only to match the bridge geometry and cable forces specified on the as-constructed drawings but also to be calibrated using the vibration measurement data captured by the Wind and Structural Health Monitoring System. This paper further describes the analysis of axle loading data, as well as the generation of random axle loads and simulation of vibrations of the bridge using the finite element models. Various factors affecting the vehicular loading on the bridge will also be examined.

This study was started with its consideration as materials showing original shapes of temple buildings in the late period of Chosun the photographs and drawings which contained in $\ulcorner$A Survey Report of Korean Architecture$\lrcorner$ made by Sekino Tadashi through his survey for 62 days(July 5${sim}$Sep. 4, 1902). Results of the study can be summarized as follows. During the period of Japanese occupation, Beomesa temple experienced frequent changes in building layout including the transfer and removal of buildings. Such frequent change began in spring, 1936 when a Buddhist monk of Beomeosa temple, Cha Woon Ho moved Gwaneumjeon, originally located to the light of the main building, to the left of the building and, on its original site, built up a 7-storied sarira tower. Though it is difficult to say that the study provides everything about Beomeosa temple, the researcher expects that the study would be the very basis on which changes in the building layout of the temple since the late period of Chosun can be researched. In conclusion, the researcher hopes that the above mentioned restoration plan would help originally restore or enlarge temples, further transmitting such restored or enlarged establishments as valuable cultural remains from generation to generation. In this respect, the researcher expects such restoration plan to be made in continuous and more detailed ways.
