The comprehensive Topic of Total Quality Management (TQM) has been put forward since the 6^th decade in industrial countries. The serious attention to it in developing countries goes back to recent years. Unfortunately serious attention is not paid to quality issues in building industry. Therefore, the construction of buildings is highly vulnerable against natural events while having low effective lifetime. Wide-range destruction of the residential buildings in the earthquake of Bam ( in IRAN ) is a clear proof for this claim. In this paper we tried to present the corresponding effects between quality issues and other aspects of a building project (such as costs) and proposed general solutions to improve quality indices in construction industry.

In a reinforced concrete structure, coupler construction is easier to install than jointing or welding reinforcing bars, so it is possible to work by one person. When constructing a reinforcing bar coupler, the coupler construction method must be different for each member that receives a large tensile force or a member that receives a small tensile strength. Various coupler products are used in the global construction market, and the quality, performance, and cost of reinforcing bar joints vary from product to product. This study compares and analyzes the quality and cost of representative rebar couplers according to the requirements using the quality house of QFD-HOQ. The case study presents a quality and cost improvements strategy through QFD-HOQ analysis of rebar couplers.

Modular system is a construction method which installs factory-manufactured units on site. It enables to reduce the duration and improve the quality of the construction. Nevertheless, the unit modular system is restrictively applied to domestic market such as barracks, education facilities, low-rise housing. To motivate the application of unit modular system, this study figures out important attributes of the unit modular system in a domestic construction market. Finally this study suggest marketing strategies and influential factors by Importance-Performance Analysis(IPA) based on those attributes focusing on the apartment housing. As a result, Unit modular System in the domestic market has strength on constructability, but it show weakness on usability and economic aspects which are more important in apartment housing market. Thus an improved technology in usability and economic aspects are required to activate the market.

The purpose of this study is to analyze the problem of BTL business through the sensitivity analysis of financial model and presented efficiency business strategy when private business owner propose their business. For this, we analyzed the sensitivity of financial model after analyzed costs of the school facility construction case for each place of business. The results of this study are as follows. 1)As the results of the sensitivity of financial model, requirement-earning rate for the results of analysis was decreased average 2.28 points (0.5%) per increasing 0.10% and Construction costs and the maintenance costs were decreased average 10.73 points (2.38%), 6.22 points(1.38%) for increasing 1billion won. 2) The Problem of BTL business according to the sensitivity analysis of financial model was analyzed that the price consultation low investments, and estimation from personal consideration caused it. So, it was analyzed to increase maintenance costs is more efficient method than to increase construction costs.

Korea companies have been faced with the demand of environmental changes abroad by suffering Economic Crisis at 1997. In fact, these demand that modern firms are in the keen struggles for existence is the essential condition though of the age of Economic Crisis. Coping with these situation. these companies are making desperate efforts, which are reorganization, renovation, improvement, however, the procedure or the result about these efforts of change have to be checked wisely. That is, the firms have to meet requirement that could enhance their values because organization structure that is not efficient to growth of firms produces a quite contrary result. Such phenomenon is applicable to construction firm as well as limited with partial companies. Therefore, before forming a efficient organization structure, comparing and analyzing the strategy or financial statement according to construction firm, this study will try to grasp a characteristic of organization.

Knowledge management was introduced as a new strategy in many construction companies aiming at paradigm shift since Asian financial Crisis. However, intensive focusing on acquiring and sharing knowledge couldn't keep pace with the primary goal. Increasing financial profits. That is because clear strategic process and performance measurement are absent in time of the introduction of knowledge management. Based on case analysis in domestic construction industry, this research work presents an alternative plan on Balanced Scorecard(BSC) model. The objective of this study is to develop a model of strategic performance measurement in knowledge management by sorting and grasping core operational knowledge, which can draw key performance indicators accompanied by knowledge map from case study.

This paper aims to presents a systematic procedure for the development of construction technology roadmap, which can consider the offshore wind farm on port. Then the weight among the large/medium/small classified construction technology has identified through the AHP(Analytical Hierarchy Process) approach using FGI(Focus Group Interview) and questionnaire study. Based on the priority for classified construction technology a construction technology roadmap for port offshore wind farm was also developed. The technology roadmap suggests the time frame(20 years, from 2016 to 2036) to complete R&D work for the classified construction technology of port offshore wind farm. Such construction technology roadmap can be utilized as a milestone in setting up the R&D strategy in the green port construction industry.

As the government announced Real Estate Policies on August 02, most areas except for Seoul cities face increasing business risks. Moreover, the government control over financial sectors' loan leads to the highly possible contraction of new distribution markets. The market trend could bring about the reduction of new demand in PF (Private Financing) business that large construction companies mainly concentrate on, and even the business already obtained has a high risk of being distributed, which could result in substantially low profitability. The currently unstable financial structure of most construction companies is caused by the hike of the prime cost of foreign plants except for that of a few construction companies. If PF (Private Financing) business also faces a difficult situation in such a financial condition, even large construction companies come to have the high possibility of a deficiency in credit rating. Accordingly, the major business that large construction companies concentrate on needs the sufficient business review. It is desirable to make a bid for business guaranteeing stability rather than business solely in consideration of profitability, when participating in a competition for a new construction contract.

The purpose of this research is to provide basic data for the promotion strategy to activate modular construction system as residential facilities, through a study on the architectural planning, institutions and policies and research on connection details, for the use as residential facilities of the modular construction that is not actively supplied for the general residential facilities. As a result, I suggest sample model plan of domestic and foreign case analysis and characteristic of modular construction and practical application of modular construction for Residential Facilities. Owing to many advantages including short construction period structural stability and economic benefits, modular construction is expected to play a role as residential alternative of socially controversial affordable housing and weekend homes, and potential housing shortage after reunification; and to contribute to the development of design automation and industrialized constructions. Though Korea is still lacking development of the system that meets the domestic context, if supported by ongoing researches on the development of construction methods, materials and details, the settlement of appropriate modular residential facilities to suit the national situation will serve a possible alternative solution for many housing and environmental problems.

Delays in completing construction projects have significant financial and social impact to all parties involved in the construction process and in particular in developing countries. This is very evident in most construction projects in Libya and in both public and private sectors. The research study was initiated by Libyan Government and the main aim of the project is to develop a new strategy in reducing the impact of delay factors. In order to achieve this, a number of objectives have been set-to conduct a comprehensive literature survey, to conduct a comparative study of the delay factors in project completion in both Libya and UK using semi structured questionnaire and finally, to identify and analyse the causes of delay and ranked them using frequency of occurrence and severity. The critical causes of delay for construction projects were quite different between Libya and UK. For the former, the most critical causes of delay in Libyan construction industry were low skills of manpower, changes in the scope of the project, slowness in giving instruction and poor qualification of consultant, while for the latter they were financial problems, bad weather conditions on the job site and change in the scope of project. Statistical experiments including Paired Samples T-Test, was run to test the significance of the survey data in both countries Libya and UK. The statistical results confirmed the collected data from the survey were significant.
