The cost of low-income groups's housing expenses have been weighting since 2000. To solve this problem, governments encourage supplying rental apartments for them. House rental supplement is most common things to solve housing problem in an advanced country but there is neither earning rate nor assessment standards in our country. Therefore, studies on house rental supplement are required to develop this systems. Hence in this study, we try to suggest both proper house rental charge to encourage nongovernmental construction and house rental supplement, considerng ability to pay.

Korean Journal of Construction Engineering and Management, volume 8, issue 2, 2007, Pages 68~74
It has been recognized that safety management is activated during the construction phase to prevent accidents and fatalities of workers. However, It is revealed that about 15% of fatal death accidents is caused by the lack of management of planning and design phases. There is a crucial need of assessing safety risk during building design phase. This paper is aimed to develop a safety risk assessment checklist that can be used during building design phase, utilizing the concept of Design for Safety. In doing so, a broad literature survey on safety management of building Process, various safety risk assessment toolboxes being utilized in the HSE and the BAA of UK. The proposed checklist contains the followings: 1) classification structure for safety design on space, element, and trade work 2) hazard risk factor, probability and degree of intensity of accident occurrence, and 3) safety assessment criteria. It is expected that the checklist would be an effective tool of preventing and minimizing fatal accidents of building construction projects.

Recently, the Design-Build (DB) delivery method in public sector makes some argument by reason of the initial cost which is more higher than those of Design-Bid-Build (DBB). According to the results of pervious researches related to the performance evaluation of delivery method, DB can lead the reduction of project cycle time and also is superior to the traditional DBB in terms of construction quality. The performance on each delivery method could be generally evaluated by a project cost and a project cycle time as one of quantitative analyses, and also by construction quality as one of qualitative analyses. In most researches, the evaluation of performance level based on delivery methods has been evaluated by the degree of their satisfaction through the interview with owners. Therefore, this paper analyzed the design documents of construction projects delivered by traditional DBB and DB in bridge construction projects in order to measure design quality, constructability, maintainability, and etc. As an above-mentioned analyses, finally, this research shown that how much the difference of performance level is by each delivery method.

To reduce uncertainties and make rational plans, the presumption of contingency against a failure of projects and an occurrence of unpredictable risks is important with accurate estimations as the work progressing. Therefore, if the presumption of contingency reflecting uncertainties carries out at a decision making point of time, be able to prepare for risks. The purpose of this paper is to present a management process of contingency through the performance analysis of project. In the cost planning phase, this study offers a process which is predictable contingency and predicts the range of fluctuation of the cost, laking an advantage of EVM in construction phase. With reflecting the results from this procedure, this study presents a process, rationally manageable contingency.
Public Infrastructure Practitioner's Recognition on Project Performance
Park, Hee-Sung ;
Korean Journal of Construction Engineering and Management, volume 8, issue 2, 2007, Pages 93~100
Performance measurement and evaluation is a critical issue in public funded civil infrastructure projects in recent years. As a results, Korean government has introduced the related policies and regulations based on the foreign cases to evaluate public construction projects. However, construction circumstances are different from other countries and the results from adopted regulations are not satisfied. Therefore this research proposes the critical success factors(schedule, cost, productivity, change order, safety, quality) for public construction projects based on previous related research outputs to successfully implement construction performance evaluation. Then, this paper also proposes the weights for the critical success factors. The proposed weights are developed by AHP of construction experts. Furthermore, the paper shows the difference of the weights of the critical success factors by project participants (owner, constructor, engineering, and inspector). This efforts will enhance the ability to develop an effective performance evaluation process and system for public construction projects.

Currently construction corporations also is whether executing or planning IR activities as other corporation do. We will analyze correlation between stock price and IR activities and execute actual analysis of how IR activities influence stock price in order to identify positive influence of IR activities on Construction Corporations which are executing IR activities for raising capital and investors. We make two hypothesizes through searching thesis and interviewing experts. Two hypothesizes are as follows. First of all, stock price will increase in terms of public of IR activities. Second of all, IR activities targeted on domestic investors will be very successful. We deduce conclusions through verifying two hypothesizes. Conclusions are as follows. First of all, IR activities of construction corporations influence stock price positively. Second of all, IR activities targeted on international are more effective than on domestic Third of all, even though IR activities targeted on domestic is less effective than on international, it is indicated that it have positive influences. Construction corporations give investors frostiness and then will expect to raise capital and renew
imageby well executing IR activities.

Lee, Sung-Goo ; Park, Tae-Keun ;
Korean Journal of Construction Engineering and Management, volume 8, issue 2, 2007, Pages 109~117
The construction environment has the trend of oversizing and professionalizing, the increase of the construction period, and the risk factors and the uncertain factors which are important in the construction bid. The misunderstanding and the lack of knowledge of the subcontractor result in the decrease of the profit or the deficit. In conclusion, these are supposed to give the financial burden to the subcontractor. So, it is very important to predict the construction preparation cost calculation by the risk factors in the bidding stage and to calculate the bid unit cost considering the target profit of the subcontractor in the process of the mutual agreement and performance of the contract. In these points of view, this study analyzes how the importance of the risks influencing the bidding cost calculation affect the construction cost, and this analysis can be used as the basic data to establish the suitable bid strategy of the subcontractor.

Korean Journal of Construction Engineering and Management, volume 8, issue 2, 2007, Pages 118~126
Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Apartment residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling construction has a unique characteristic in that the residents are already determined prior to construction execution. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.

Markets for the apartment remodeling projects will be a major portion of the construction industry in near future. However, only partial remodeling works in the apartment were done so far. This situation caused bad impact to expand the remodeling markets and less profits of the remodeling projects. In order to solve this problem, many other researches were done previously to Improve profits of the apartment remodeling projects. However, the results are too theoretical to implement them and Improve profits. In this research, profitability influence factors that are possible to improve effect of the remodeling works are selected and analyzed through several studies. Then, correlation analysis is performed between the improvement level in the remodeling projects and the numerical profitability based on actual cases. The result clearly shows that some improved remodeling items are strongly related to the profit. These results lead us to the strategy to follow for the purpose of increasing profits of the remodeling projects.

The u-City construction project has become a hot topic In the construction market because it seems economic value-added field for construction firms. However, construction firms don't willingly participate in the u-City construction market because the future business environments for the u-City are very uncertain. Scenario planning is a very powerful method in managing this complex planning situation and is based on scenarios that help each enterprise appropriately adapt itself to its own business environments. Therefore it Is based on the main principles of systems thinking and multiple futures. For the purpose of dealing with such uncertainties, this paper attempts to develop the possible market scenarios of the u-City construction market through a scenario planning approach. From this perspective, we considered various aspects of the u-City construction such as market demands, technology development, policy level and management environment. After considering the relevant issues, we identified the main trends and key uncertainties. Then, we developed three coherent u-City construction market scenarios. On the basis of the proposed scenarios, the business strategies of potential construction firms in the u-City construction market has been formulated. Therefore, construction firms can use these scenarios as a basic data for market analysis and business strategy. Therefore, this paper is able to enhance the participation of construction firms in the u-City construction market.

Korean Journal of Construction Engineering and Management, volume 8, issue 2, 2007, Pages 155~163
Multiple parties-owners, engineering and construction contractors, and suppliers involve the delivery process of capital facility projects in the construction industry, and each party obtains or provides their workforce, material, equipment, or service tied into specific contracts. Considering that construction projects are based on the contracted relationship between the parties and that contract types are one of the significant factors determining project success. it is critical for project stakeholder to select appropriate contract types for successful deliveries of projects. With these considerations, this paper assesses impacts of different contract types on project cost, schedule, safety, change, or rework. Analyzing data from real construction projects, the differences in project performance between two contract types, Cost Reimbursable and Lump Sum are measured and statistically tested to investigate if the differences are significant. For this analysis, performance metrics developed by Benchmarking and Metrics program, the Construction Industry Institute are used.

The development project usually aims to get a certain amount of return for its investment in land and capital. The success of such project is dependent on the accurate analysis of the feasibility and for casting. It is, however, very difficult to predict due to various environmental factors. For this, it is necessary to constitute a systematic and objective method of analysis. However, there is no method of analysis for numerous qualitative factors, such as legal, environmental, marketability. Moreover, conventional methods have some limitations because they are processed without all the scope of analysis items and any evaluation criteria. Therefore, this study will provide computerization model for feasibility study focusing on the apartment development project by a pre-sall method. This research does casestudies to assess the feasibility analysis by the computerization model and compares to the results of the conventional methods. It showed that the evaluation results for the qualitative analysis were proportional to actual sale result. This implies that qualitative subjective factors have high correlation with sale rate and sale prices.
