Fly ash has the advantages, among others, of improving the characteristics of concrete, reducing the price of concrete products, improving the durability, and reducing hydration heat. However, when added in mass, it leads to problems such as insufficient concrete intensity, increase of AE use, and others, resulting in a limitation of the use volume. Therefore, this study is undertaken to solve the problems associated with themass use of fly ash through the high concentration powder (
) of fly ash, curing method, the addition of an alkali stimulation agent and others for the purpose of increasing the added value of the fly ash. The research showed that the intensity manifestation has an outstanding status, with the hydrates reaching a very stable condition if the rate of addition of a stimulation agent is appropriately used with the heightening of the fineness of the fly ash in the temperature range of
, and if the applicable study is continued, it is likely to result ineffective value generation on the massive replacement of fly ash.

A competitive construction project must address factors such as cost, performance, aesthetics, schedule and quality. The importance of these factors will vary from project to project and from market to market. Productivity is becoming an ever-more important factor in the acquisition of a project. As the technology or aesthetics of a product matures or stabilizes, and the competitive playing field levels, competition is increasingly based on time. Recently, the construction industry has been depressed due to difficult market circumstances. At this time in particular, construction companies are striving to rationalize their management, both in their planning offices and in the field. In this study, we present a method of calculating a reasonable duration for reinforced form work. We did this by first developing a question for field workers, then sampling form workers based the question. Second, we employed a work analysis method to analyze worker"s work-methods and Time. Then, using the result of this analysis, we measured the Productivity of form work. This measure can be used as basic data to determine the appropriate duration of form work.

The bearing wall apartments which occupy the majority of multi-residential apartment buildings built in Korea, are known for having limited architectural plan flexibility, posing challenges in terms of maintenance and remodeling. The economic losses and environmental issues resulting from the reconstruction of bearing wall apartments are now accumulating to the extent that they are becoming a national concern. Multi-residential apartment buildings, which are now the dominant form of residence in Korea, must accommodate diverse customer needs and changes in life style. A new concept of Rahmen structure with architectural flexibility is Green Frame. GF multi-residence housing is expected to reduce construction costs and shorten the construction schedule by overcoming the shortcomings of conventional bearing wall apartments. This goal is consistent with the national policies that target the reduction of resource and energy consumption. In addition, GF will be established as a core contributor to achieving a reduction in
emissions, which will enable the sustainable growth of domestic construction industry, and address the low-carbon green growth drive implemented by the government.

The failure of expansion joints for bridges generally occurs in non-shrinkage mortar another problem is the release of anchors in expansion joints due to the impact and vibration that occurs when cars are driving over a bridge. In this study, to overcome the failure of expansion joints that is related to the failure of non-shrinkage mortar, an elastomeric mortar has been developed. The elastomeric mortar has a highly developed pull-out capacity compared with that of non-shrinkage mortar. Moreover, an anchor system that can be changed easily and prevent the fracture of expansion joints has been developed.

Deck plates have been widely used for steel framework due to their merits in terms of schedule reduction and work repetition. For this reason, most of the previous studies related to deck plates have focused on the development of form type and their constructability. In this study, through an actual case study and interviews with experts, a simulation model was developed using the CYCLONE method. Based on this model, this study not only analyzed the productivity of the work process of the deck plate in steel framework, but also identified the occurrence of idle time in the work process. In addition, using a sensitivity analysis, productivity and duration could be analyzed according to variation of input resources. Based on the results, this paper suggests a way to improve the productivity of deck plate work in steel frameworks. Using the model, it is expected that project managers would be able to predict the productivity and total duration of the deck plate work in the early project phase, which will enable managers to make an appropriate plan for input resources.

Since 2004, the government has changedthe cost estimate system to one of an actual cost basis in order to calculate the optimum construction cost by reflecting changes in circumstance on the construction site in a timely manner. Currently, this is being applied to public construction work forover a billion won of actual cost data in estimation by contract unit cost. However, directly reflecting actual cost, which for large-sized construction work was originally an average unit cost, to a small building, entails the application of a low discount rate for the cost of materials, labor, etc. and therefore can frequently give rise to cases in which the actual cost of work performed exceeds the contract sum, which in turn causes problems such as decreased revenues, bad effectson business operation, productivity, etc. Therefore, to apply actual cost to small-sized construction work (less than a billion won), there should be a plan to modify unit cost in a manner that can reflect project scale, etc. in order to resolve the problem of unit cost application of actual cost to small-building construction projects. The unit cost modification model for proper actual construction cost in small-scale construction projects developed by this study will help to increase the relevant productivity and proper gain, preventing the aggravation of business operations. Organizations placing orders are also expected to be able to secure a more realistic construction cost in arranging the budget.

The purpose of this study was to present the 6 sigma technique in construction projects, and to review the possibility of 6 sigma introduction. DMAIC (Design, Measure, Analyze, Improve, Control) methodology was used to increase the utilization of TIMS (Technology Information Management System). The results of this study were as follows. The introduction of the 6 sigma technique was very effective in the construction industry, but there were many difficulties in its application because of the characteristics of construction. As the 6 sigma technique emphasizes management based on data, it is essential to accumulate historical data and to achieve the standardization of the construction business process. Furthermore, it is necessary to apply 6 sigma for the competitiveness of the construction industry, and the development of suitable 6 sigma methodology for the construction industry is required.

Under the Civil Code and related law in Korea, the liability for defects after delivery belongs to the Contractor. However, various disputes have occurred in relation to the remedy of such defects and the compensation for damages, which are the main liability of a contractor in the event of defects. Despite court decisions regarding defect liability, many problems prevail in the real world. For this reason, this working-level research considers the introduction of a performance warranty contract system. To establish the system successfully, it is necessary to analyze the trend of various warranty cases in the US. Therefore, the warranty system of the US was first examined, and the effect of acceptance, notification and burden of proof, remedies under warranty clauses, and default termination were investigated and analyzed in this study.

The public construction industry in Korea involves a variety of stakeholders, encompassing multiple layers of contractual relationships that crisscross between the State as project client and the contractors, as well as subcontractors. In such a hierarchical landscape, managerial crises of contractors involving bankruptcy or insolvency can result in unexpected damages for both clients and subcontractors. Accordingly, the applicable legal framework requires project clients to act as patrons in relation to making payments to subcontractors, and stipulates provisions pertaining to direct payments to subcontractors in order to promote the balanced development of the national economy in terms of the public interest by protecting small and medium-sized businesses working as subcontractors for large businesses. However, the relevant legal documents provide for different payment criteria and procedures from document to document, and leave room for variations in the interpretation and construction of applicable provisions, which leads to disputes and discrepancies in court rulings. For this reason, it is necessary not only to compare and analyze statutory provisions pertaining to direct payment to subcontractors, but also to review issues of contention in actual cases. This study aims to analyze issues in cases involving payment to subcontractors from the perspective of the project client overseeing and supervising the construction business. The conclusions from such an analysis will help to effectively resolve subsequent cases of a similar nature by suggesting a strategy to improve the relevant statutory provisions pertaining to direct payment to subcontractors.

When constructing housing, various factors affect the housing purchase price. These factors are considered in the whole process of construction, and the feasibility of a project is then studied based on these factors. Recently, Highest-end Housing in Gangnam has a large market ofpotential and fixed clients in the Korean construction business. However, there has been a lack of research related to the Highest-end Housing market thus far. Therefore, this paper focuseson the factors affecting the Highest-end Housing price, and the level of the effect. Ultimately, the results of this research could be used as basic information for enhancing the competitiveness between the construction companies that build villa apartments,and support the business model.

The mechanical properties of stone structures are generally characterized according to the strength of the stone used. An ultrasonic velocity method that does not damage cultural heritages is used to measure the strength of stone. However, there is no correction involved for surface roughness and thickness of the stone in the ultrasonic method currently used. In addition, a contact agent such as grease can cause contamination on the surface of a cultural heritage. Accordingly, this study suggests an indirect method of strength estimation formula for stone structures based on the surface roughness of the structure, its thickness, and the type of contact agent. (1) Rock strength estimation formula using ultrasonic velocity method of dabbed finish :
(2) Rock strength estimation formula using ultrasonic velocity method of harsh finish :

The recycling of demolished concrete as an alternative source of coarse aggregates for the production of new concrete can help to solve the growing waste disposal crisis and the problem of the depletion of natural aggregates. The purpose of this study is to investigate the chloride migration of recycled aggregate concrete containing pozzolanic materials by the chloride migration coefficient. The specimens were made with recycled coarse aggregate at various replacement ratios (10, 30, 50%) and metakaolin, blast furnace slag, and fly ash is replaced for recycled concrete with a mixing ratio of 20%. The major results are as follows. 1) The compressive strength of recycled aggregate concrete containing pozzolanic materials increases as the curing age and chloride diffusivity decreases. 2) When the replacement ratio of recycled coarse aggregate is 30%, the chloride migration coefficient of recycled concrete containing blast furnace slag or metakaolin that shows a value similar to or lower than that of plain concrete at all ages.

Following the successful entry of Korean builders into overseas construction markets, Korean architects have also become active abroad, and have expanded their market share centered on the Southeast Asia and Middle Eastern areas through Design-Build contracts. However, there have also been However, conflict can arise among the project applicants in the contract stage due to the special characteristics of overseas construction. This sometimes leads to the failure of a project. Using statistics and case studies, this study identified problems in the overseas construction market. It analyzed inefficient factors of the architectural design contract phase in the overseas through a survey and an interview of specialists. Based on the results, this study suggested a master architect system, and some resolutions to the problems of organizing an internal evaluation system. It is expected that the results can be used as practical data for companies that want to advance into the overseas market.

A significant number of projects have been managed by US Army Corps of Engineers FED. Today, more information must be provided to the parties involved in the projects by phase than ever before. Specifically, USFK`s construction projects have been managed by FED(Far East District). Recently, however, large US private construction companies have been filling the role previously taken by FED. However, there is few construction managers to implement FED project in Korea. Accordingly, this study analyzes FED projects practices with focus on the construction management actors in order to suggest guideline. This study suggests a model FED construction process(Bid, Contract, Construction, As-Built Phase) by analyzing the existing FED project process using a IDEF0 methodology.

Journal of the Korea Institute of Building Construction, volume 10, issue 1, 2010, Pages 175~180
DOI : 10.5345/JKIC.2010.10.1.175
Despite continuous efforts by the construction industry to achieve better quality, it doesn't seem that much has been improved. This is mainly because current specifications do not satisfy a change in the market environment, which is that a higher level of quality is now demanded by users. Quality improvement efforts have been satisfied merely to meet specifications. On the other hand, advanced countries have been experienced great success in their construction techniques and have reduced costs by introducing apay adjustment system to the construction industry, in which compensation is based on performance. Following their example, Koreashould introduce such a pay adjustment system in order to motivate the members of our construction industry to achieve better quality and a higher level of construction techniques. However, there has been a lack of a rational approach to the development of a system for cost coordination, as well as performance and quality inspection. Thus, in this study a legal and logical plan was developed that can be used to adjust the construction cost, along with the performance inspection of quality results, in order to introduce a pay adjustment system that is appropriate for domestic regulations.

Park, Hyeon-Ku ;
Journal of the Korea Institute of Building Construction, volume 10, issue 1, 2010, Pages 181~191
DOI : 10.5345/JKIC.2010.10.1.181
Lightweight panels are currently used in many ways, such as inner walls of the skyscrapers and residential buildings in Korea. Moreover there has been an increasing of interest in developing construction method and quality improvement as many buildings became higher, because there are more advantages like constructability, finishability, and economic efficiency, etc. than previous heavy weight concrete wall. It is necessary to analyze the characteristics and evaluate the performance of lightweight panels when selecting proper methods and materials to building characteristics and builder's demand. However, there doesn't exist systematic data with a classification of lightweight panels' type and performance. The purpose of this study is to classify domestic lightweight panels by both type of exterior board and construction method, and also to evaluate each performance by surveying user's opinion.

Kim, Jong-Rok ; Son, Jae-Ho ;
Journal of the Korea Institute of Building Construction, volume 10, issue 1, 2010, Pages 193~198
DOI : 10.5345/JKIC.2010.10.1.193
This study aimed at presenting the improvement plan for estimation of the repair and replacement cycle to analyze these current problems by considering the repair and replacement cycle theoretically and examining estimation status of home and abroad, and then drawing implication and problem based on brainstorming and expert opinion. The findings of a study is as follows. First, the problem is, for the domestic, that there is no clear standard of division to the cycle of repair and replacement and the repair and replacement cycle considering capability to deal with the change by construction method, development of the function of material and the number of years of progress is not being applied. That is, an estimation of economical repair and replacement cycle which considers the case that a large scale repair with the level of remodeling is done between 25 years and 35 years is necessary. For estimating the repair and replacement cycle, foreign country is providing this according to the use or the level of function of a building, but it is not the case for the domestic. A characteristic of each building should be reflected and the standard of estimation of the repair and replacement cycle to new construction material or method should be prepared to improve this. In addition, the method of classification of the subject item for the repair and replacement is necessary to be reorganized to be able to apply the standard of initial construction item of a building. Also, it is considered that a service standard which can reset the repair and replacement cycle based on status of a building with escape from the existing definite setup of the repair and replacement cycle through the management of background data of the repair and replacement is going to be necessary.

To establish an infrastructure for technology and information in the domestic construction industry, several construction regulations pertaining to construction information have been institutionalized. However, there are major problems with the domestic information classification system, earned value management (EVM) and project management information system (PMIS). In particular, the functions of the current PMIS have consisted of a builder-oriented system, and as EVM is not applied to PMIS, the functions of reporting, analysis and forecast for owners are lacking. Moreover, owners cannot confirm information on construction schedule and cost in real time due to the differences between the EVM and PMIS operation systems. The purpose of this study is to provide a framework that is capable of operating PMIS efficiently under an e-business environment, by providing a proposal on how to establish a work breakdown structure (WBS) and an EVM - PMIS integration model, so that PMIS may provide the function of EVM, and stakeholders may have all information in common. At the core of EVM - PMIS integration is the idea that EVM and PMIS have the same operation system, in order to be an activity-based system. The principle of the integration is data integration, in which the information field of an activity is connected with the field of a relational database table consisting of sub-modules for the schedule and cost management function of PMIS using a relational database management system. Therefore, the planned value (PV), cost value (CV), actual cost (AC), schedule variance (SV), schedule performance index (SPI), cost variance (CV) and cost performance index (CPI) of an activity are connected with the field of the relational database table for the schedule and cost sub-modules of PMIS.

The research, based on 200 cases of small interior works in6 different floor area types of apartment in Busan, intended to compare the architectural work with the breakdown structure and analyze the cost of general small-scale interior work, by work type. The outcome of the research is outlined as follows. (1) Given the cost of small interior works for apartmentsranges from 10 million to 15 million won, which correspond to apartments ranging in size from
, it is necessary to implement a cost analysis for material cost and labor cost for these two types. (2) Given that small interior work for apartments comprises mostly finishing work, unlike the categoriesof general architectural work, it is more reasonable to classify the works into 9 categories,which include embellishment, wood, tile, paint, metal, toilet, sink & furniture, electric & mechanical and other works, instead of the 22 divisions stipulated in the Korean Architectural Standard Specification. (3) After reviewing the average cost of small interior work and rate by floor area, it was found thatthe average cost of 24PY was 10.5 million won, of which metal work accounts for 12.8%, embellishment work 17.8%, and toilet 19.7%, while sink & furniture appeared to be the highest with 22.1%, while for 32PY, average cost was 12.5 million won,which comprises 7.4% wood work, sink & furniture 20.2%, toilet 23.4% and embellishment work the highest at 28.6%, indicating that embellishment work accounts for the greater portion.

A construction firm's performance is largely attributable to performance in individual projects. In this regard, the awarding of an individual project has significant implications. However, project awards have received limited attention in the construction sector from amarket assessment perspective. This event study focuses on an analysis of market responses at the time of project awarding. A total of 252 samples wereselected through a rigorous sample screening processes. Performance was measured as cumulative abnormal return, which is traditionally adopted in event analysis. Research results indicated that the overall return is positive, and that the level isstatistically significant. Equity holders realized a higher return for projects awarded from the foreign countries compared to domestic projects. No relationship was observed between project size and the level of return. Other research findings and implications were discussed in detail from a management perspective.
