The goal of this research was to build comprehensive and systematic basic materials related to IT industry and spatial design. In this research, the trend in spatial design research and its categories are identified and analyzed. The research results show that spatial design researches related to web have declined for last five years. However, a new possibility appears to be latent. An attempt to build database of diverse design information has led to increase in fusion of spatial design education and IT technology from design perspective. Futhermore, residents of space are becoming more active, starting from spatial design to management. Finally, from th environmental perspective, researches on predicting and managing buildings are also growing. Accordingly, diverse researches and financial support for grafting creative education, design process, environment-friendly IT technology and spatial design are needed.

According to previous research, the reason why Design-Build(hereinafter "DB") outperforms Design-Bid-Build(hereinafter "DBB") in terms of cost is due to less change orders(hereinafter "COs"). However, if biddropping was low for DBB resulting into increasing COs, then it would be wrong to conclude that DB is superior due to less COs. Therefore, in order to confirm such misjudgment, the attempt to comprehensively analyze biddropping, COs and delivery method was made as previous methods had analyzed either the relationship between delivery method and COs, or biddropping and COs. This research uses path analysis, which simultaneously compares effect sizes on COs according to delivery method and biddropping based on the project type, and validated the mediator effect. The research proved that DB outperforms DBB due to less COs cannot be validated as biddropping caused a mediator effect by intervening between the delivery method and COs for specific project types. Therefore, the mechanism of delivery method acts on COs through biddropping was established. Also, the identity of biddropping was investigated in a different perspective from previous research. Based on this result, this research is expected to help determine a delivery method by considering the mediator effect of specific projects and evaluate performance.

Design-build (D&B) has been broadly perceived as an effective project delivery method and become popular in the world. However, the implementation process of this innovative procurement method in Vietnam encounters difficulties due mainly to unfamiliarity and inexperience with the approach. Critical success factors (CSFs) which could be used to enhance the project execution are useful to practitioners in Vietnam if identified. A questionnaire survey was employed to identify CSFs of D&B projects in Vietnam. Parties' competence, especially financial capability, and contract documentation are the most important factors significantly affecting project success. It was also shown that the perspectives of two principal parties in D&B projects on the CSFs are statistically correlated. The identified CSFs were then validated with some various D&B projects. The execution results of CSFs' were compared with the projects' performance measured try key performance indicators (KPIs). The most important success factors of this study were also compared with other countries'. The validation and comparison results provide project participants with some useful information to perform D&B projects better. Practitioners should well perform the identified CSFs to enhance the chance of the success of D&B projects in Vietnam. The findings of this study are useful not only to Vietnamese practitioners but also to others who are concerned about D&B method and plan to employ it in Vietnam in future.

In the past, a strategic management of work demands has been increasingly challenged to design-build (DB) firms. Such a management is capable of providing sufficient profitable impact of a project on them. Total project profit is mainly related to actual resources, work completion time, amount of rework, and costs. The degree of recycling work packages in the DB project delivery system is used as a measure of the quality of the performed work. However, there are few models available to evaluate the impact of a demand management strategy on the DB firms and to predict its behavior. We propose a decision-making support model as an aid for assessing the amount of rework and for predicting project profit resulting in a convincible demand management strategy. This model is constructed by using a dynamic feedback approach that can analyze the problems arising in complex managerial systems. For the purpose of illustration, widely acceptable strategies were applied into the model to explore their impacts on the DB firms. The results indicate that the model is helpful for the managers in selecting the most appropriate demand management strategy for successfully achieving their objectives.

Identity of the place where the physical location and time and spatial context, and is structured as socially agreed symbols to build a consistent image, while fraught with Differentiation can be achieved through integration. And discrimination and the practical and effective deployment of an integrated image to be useful as a guide for the top design 'Design Guidelines' are, The findings, where the identity used to establish guidelines for the design for the following conclusions can be drawn. First, of public space design guidelines agreed upon by the public and social identity as the basis to establish a new identity as a contemporary and practical plan for this is to provide guidance. Second, the design guidelines in principle, the physical elements and activities of the parent and the temporal and spatial context and meaning were overridden. Third, the horizontal axis with respect to the identity and principles to guide development in the detail, and the vertical axis as a place to build an image in order for the specific design items are listed. Fourth, the guidelines can set a specific motif, and coverage including identity of the place. Fifth, by applying image and schematic the identity can be Implemented effectively and clearly. Without interfering with the designer's creativity and implement new image of the place, Design guidelines should study how a reasonable instructions.

This paper focused on problems of design, construction, and maintenance caused by construction implementation processes. They were analyzed through case study of structure safety diagnosis projects. From the case study, it is expected that the introduction of Construction Management from the first stage of procurement will improve construction cost increase or burden on small design company. It strengthens coherent management from design and source contractor selection to build review of responsibility. The coherency will prevent changes in designing or infirm unreliable construction. It is desirable that expert opinions are considered when structure changes and establishment occur and that, if necessary, actions such as source selection, periodic audits, and diagnosis arc checked and fed back to maintenance.
