This study analyzed the effects of building and greenhouse structural code on the structural design and the greenhouse construction cost. The over-design possibility of greenhouse was analyzed when building structural code was applied using standard smart greenhouse drawings. The possibility of decrease in greenhouse construction cost was investigated if the currently applied building structural code was replaced with greenhouse structural code. As a result of comparing the member sizes with the standard drawings, building structural code was designed with 13%~74% more steel than greenhouse structural code. When building construction estimate was replaced with greenhouse construction estimate, it was possible to reduce the total construction cost of the glass greenhouse by 17% and that of the vinyl greenhouse by 14%. Since there is no standard construction estimate suitable for greenhouses, the wage unit price is set excessively, and the construction cost of the smart greenhouse is increasing. In conclusion, it is necessary to establish greenhouse structural code and greenhouse construction estimate to lower the greenhouse construction cost.

For the construction safety manager, it is expected that job stress is significantly high due to lack of expertise about new technology, new construction methods, and enlargement of scale as well as due to work intensity and unstable work hours. It is probable that such an increase in job stress not only has bad effects on individual, but also the bad effects spread to construction industry at large, resulting in rise in accident rate, increase in direct and indirect loss cost, and loss of reputation. In this context, methods for controlling construction safety manager's job stress are needed at the levels of both government and company. Therefore, this study investigated and analyzed the effects of construction safety manager's job stress on job satisfaction and job commitment, and proposed methods for relieving job stress. In addition, this study was suggested policies for higher job satisfaction and job commitment at the levels of the government and companies.

Owing to the deregulation, low interest, sufficient liquidity and etc., the real estate market has been recovered in some areas and some investment products to the degree being concerned about the overheating. In order that the construction and real estate industries, which play the considerable role in our economy, may be soundly grown toward contribution of the stable growth of our economy, it is being requested to acquire the transparency, predictability and trade stability of the international level conforming to the deregulation during the sale in lots of the building. For this reason, keeping pace with the trend of the construction industry and the current of the society, which are more and more large-scaled and globalized, it will be necessary to solve the social matters and to construct the more efficient and continuous construction management by widening and activating the field of CM through scheme of more specialized, sustainable and general CM method and establishment of new business bounded system in the construction management.

The efforts for sustainable development in building construction is widely applied by global organizations, governments, etc. However, according to the researchers, if the green rating systems on the building, it is reported that construction costs and durations are increased compared to conventional buildings. In this respect, the objective of this study is to identify the construction costs between LEED and non-LEED buildings. The scope of this study is limited in 21 university buildings of Canada. The methodology is as follows: First, the data of LEED and non-LEED buildings are collected in every university building. Second, the average construction costs per square meter is collected and normality check is conducted. Third, to identify statistical significance, the difference of average construction costs is analyzed by using T-test. As a result, it is concluded that the construction costs of LEED buildings are increased by approximately 3.8% more than non-LEED buildings. In the future, the results of this study can be applied to analyzing the additional costs according to the LEED grade in educational buildings.

Construction schedule plays a key role in project management due to its influence on the project success. Thus, it is important to identify factors affecting construction delay. The major objective of this study is to identify and evaluate factors affecting construction delay in apartment projects in Vietnam. The findings confirmed that financial difficulties of owners and contractors, contractors without adequate experience, non-available materials on time, slow site clearance, inappropriate construction methods, defective works and reworks, and lack of capable owners/project managers are the major causes of delay in apartment projects.

국내외 건설규모가 축소됨에 따라 건설기술인력의 신규 인력채용기피 및 수급상의 불균형 등으로 인해 대학졸업자의 취업이 극히 어려운 현상을 보이고 있다. 이러한 상황에서, 최근 대학졸업자의 취업률이 $35\%$미만으로 나타나는 등 건설기술인력의 실업대책이 중요한 사안으로 부상하였으나, 건설기술인력의 과잉문제를 해결하기 위한 범정부 차원의 종합적인 대책이 미흡하였다. 또한 대학졸업자의 교육성과에 있어서도 다양화, 첨단화되고 있는 건설산업 현장에서의 수요에도 부합되지 못하고 있다. 이에 본고에서는 $2003{\~}2008$년간의 건설기술인력의 수급예측을 하였고, 과잉공급된 건설기술인력의 수급효율화 방안을 마련하기 위해 SOC 투자확대, 미취업 건설기술인력의 IT분야 유도, 해외진출 확대 등 건설기술인력의 고용창출방안과 더불어, 건설관련 학과의 탄력적 운영, 기업수요에 대응한 대학교육 등 양적 질적인 측면을 동시에 고려한 건설기술 과잉인력의 수급대책을 마련하였다.

Earthwork is an operation that provides space for structures, and it takes up a large portion of the construction costs in a construction project. In large-scale earthwork, numerous types of construction equipment are used in the operation. The types of equipment should be selected based on the field conditions and the construction methods. These construction vehicles are constantly changing positions during the earthwork operation. Therefore, the equipment operators require effective communication to ensure the efficiency of the earthwork operation. All equipment operators should exchange information with the other equipment operators. Information should be exchanged continuously to support decision making and increase productivity during the earthwork operation at the construction site. This paper investigates the attributes required for an information interface between construction vehicles during an earthwork operation. This paper 1) discusses the importance of an information interface for construction vehicles in order to increase productivity during an earthwork operation, 2) analyses the types of attributes that need to be communicated between construction vehicles, and 3) provides a database that has been built for attribute control. The database built for the information interface between construction vehicles will enhance communication between vehicle operators. Table I shows the typical attributes that should be shared between the excavator operator and the dump truck operator. This information needs to be shared among the operators, as it helps them to plan the earthwork operation in a more efficient manner. A database has been developed to store this information in an entity relation diagram. A user-interface display environment is also developed to provide this information to the operators in the construction vehicles. The proposed interface can help exchange information effectively and facilitate a common understanding during the earthwork operation. For example, the vehicle operators will be aware of the planned volume, excavated volume, transportation time, and transportation numbers. As a part of this study, mobile devices, such as mobile phones and google glasses, will be used as hands-on communication tools.

The waterproofing in slab and wall of underground structure, have a couple of construction methods which are inside waterproofing methods for inner surface, and outside waterproofing methods for out wall and slab surface waterproofing. In resent years, however, it has been adapted the inside waterproofing construction method, as increasing of construction expenses cost and low workability and technology, nevertheless, outside waterproofing has set a most high value construction method. In inside waterproofing construction method, it is difficult to repair and assure durability and safety for concrete which has direct water-press. So, It is necessary for adopt the outside waterproofing method. For that reasons, this study based on the application for outside waterproofing method on the under ground structure, to more increase durability, to introduce mono adhesive sheet waterproofing materials. as considering chemical, physical properties.
