There are many elastomeric joint sealant applications in construction such as structural glazing, weatherproofing and insulating glass fabrication etc. Each sealant joints require unique durability functions to perform well through building life cycle. Elastomeric joints in bathroom and kitchen is one of areas which require durable sealing. In this application, anti fungal durability is proprietary function of sealant during building life cycle. Premature failure of anti fungus resistance of sealant is putting big stresses to general contractor as well as the inhabitants due to costly rework and poor sanitation. Accordingly, when chemists design a product, they must take into account various parameters not only formulation components also test conditions in order to have long term fungal durability. This paper reviews several biocide options with various industry standards for fungus resistance performance to suggest making new test method for construction sealant industry.

The Configuration Management(CM) of Nuclear Power Plant(NPP) is an activity that maintains consistency among the design requirement, facility configuration information and physical configuration. It is a systematic approach to performing various engineering tasks such as change management by identifying, documenting the characteristics of plant Structures, Systems and Component(SSC). The first activity that should be performed the configuration baseline setting at the start of project. The configuration baseline of the NPP construction phase is the status of the SSC of the plant at a specified process and time, and the actual configuration changes depending on the condition of plant. In this paper, I have studied the current status of configuration baseline used in the software industry and general plant industry, method of establishment for the configuration baseline which was first applied to the construction of NPP.

This study empirically validates whether the effect of strengthening the legal regulations in the construction industry under the 'Construction Business Act' is true in order to expand the direct construction of the comprehensive construction corporation. Checking the effectiveness of the legal regulation that can force direct construction of the required scope of construction will not only be a logical background in the strengthening of law regulations but also suggest arguments that contradict some construction companies called legal regulation.

There are certain types of construction that produces many defects during the construction of apartment buildings. It may be due to construction errors in the type itself, but more often, it is due to defects derived from other types of construction. Thus, to reduce such secondary defects and prevent fundamental defects in particular types of construction, academic research on the types of construction causing secondary defects should be actively conducted. In addition, as claimed in this study, the industries should work harder to improve the quality of the type of construction that causes secondary defects, rather than just trying to improve the ostensible problems. If the efforts of each sector are backed up, the disputes over defect repair in apartment building construction will reduce in general, which in turn will lead to a reduction in national loss within the construction industry.

Construction activities are characterized as hazardous work. Therefore, it is very imperative to explore comprehensively fatal accidents and safety performance in both developed and developing countries. The goal of this study was to look at the reasons behind fatal accidents in HCMC, Vietnam's largest city. The survey sample consists of 91 fatal accident cases in total that occurred in construction sites during the years 1996-2005 and were reported to the Department of Labor-Invalids-Social Affairs in HCMC. The study was conducted by means of field surveys with relevant individuals working in construction sites and statistical analyses. The research resulted in failing to wear/use PPE as unsafe acts and in poor safety management procedures/methods in sites as insecurely working conditions behind serious accidents in the construction. The paper stresses that accidents tended to occur more in state-owned companies than in others and involved more with masonry/welding people and workers without labor contracts than with other workers.

As arising concerns on environment, the social and institutional efforts have been made to establish green building in Korea. Even though the progress until now could not be underestimated, the education and information system of green architecture needs to be reconsidered. The system and the program of USGBC to cultivate green design and construction in the USA could be a good case to be explored. The results of exploration of USGBC programs are followed. First, USGBC is industry-led and consensus driven coalition and has diverse membership including building owners, architects, engineers, general contractors, government agencies and nonprofits. Second, various education programs are developed and provided not only for building industry practitioners but also for general people. Third, LEED Accredited Professionals who have detailed knowledge of LEED project certification requirements and processes are produced to make rating system go on smoothly and spread out. Forth, there are international conference and expo called "Greenbuild" and chapter events to interchange of information on green building industry. Lastly, there are incentives which are earning continuing education credits for other organizations such as AIA for attending a LEED workshop and earning a project one point towards LEED Certification. In view of above results, USGBC and its education program can be a good reference for developing ours on green building in Korea.

Construction accidents are major problem in Turkish Construction industry and especially fatally rates are very high. Current legislative system on occupational safety in Turkey enforces employers to implement safety measures as well as safety management systems. However level of consciousness in the industry is unsatisfactory and safety are perceived as extra cost and unnecessary expenditure. Moreover, especially in small residential building constructions which have a big share in the industry and unfortunately safety measures to mitigate or abate construction risks do not exist. The study focuses on small residential building construction sites and in the scope of this study, thirty building projects are examined. For each building project, project cost including labour and material costs, service and consultancy costs for mechanical, electrical systems as well as architectural and structural services, costs for supervision and finally general expenditures for construction site facilities were calculated. On the other hand, occupational safety costs for personal protective equipment, collective protective measures, consultancy and training were determined. Work breakdown structures were established and for each work item firstly occupational risks were evaluated and furthermore according to risk scores safety measures to be implemented were defined and related costs were calculated. The study gave results for total safety cost on average, in terms of percentage of total project cost (3.73% of total project cost), safety cost per man-hour (0.40 USD) and safety cost in terms of unit construction area (11.60 USD per square meter). Since safety management is a part of whole project management process, study gives suggestions and techniques to calculate safety costs and implement safety measures as a part of project management service for professionals. Authors believe that suggested approach may easily developed by the usage of more data to establish a model for estimation not only for building construction sites but also for all construction projects.

In this paper, different types of traditional project delivery methods in the construction industry were explored and a comparative analysis against Integrated Project Delivery (IPD) were performed. The advantages of IPD method for all parties, owner/engineer/architect/general contractor, were explored by reviewing the most recent literature. The literature suggests that IPD method should be the dominating project delivery method and diluting the conventional methods such as Design-Bid-Build due to more collaborative and mutually beneficial ways of doing construction; IPD is newer and a more comprehensive method to capture the intrinsic values of project collaboration. This paper presents a comparison of the commonly used methods of project delivery, Design-bid-build, CMAR, & Design-Build and addresses their advantages and disadvantages in differing project scopes and sizes. Several industry leaders with experience in the four types of project delivery addressed were surveyed. The survey results show an overwhelming desire for future projects to go toward IPD from the contractor/owner/RDP. The biggest obstacle facing a project from using IPD appears to be trust.
