The building construction is an essential field to consider weather condition because construction works are performed in a site. From this reason, this study evaluated the effect of weather condition with work sections in building construction by Analytic Hierarchy Proces (AHP) method. The results of this study as follows : (1) The effect of weather condition with work sections is affected by rainfall in summer season, and by a low temperature in winter season (2) The effect of weather condition with work sections is 0.235 for mold work, 0.210 for concrete work, 0.181 for steel-frame work.

본 논문은 시기별 국내 건설경기 변화와 해외건설수주 간의 관계성을 벡터오차수정모형을 통해 비교분석하는 것을 목적으로 한다. 분석결과 IMF 외환위기 이후에는 주거용 건설경기가 하락할 경우에만, 해외건설시장 진출이 더욱 활발히 나타나는 것으로 확인되었다. 게다가 IMF 외환이기 이전보다 외환위기 이후에는 국내 주거용 건설경기 변화에 즉각적으로 반응하여 해외건설시장 진출 규모가 확대되는 것으로 나타났다. 이와 같은 현상은 국내 건설업체들의 사업 포트폴리오 상 주거용 건설경기에 매우 민감하게 반응할 수밖에 없음에 기인한다. 즉 국내 주택시장 침체는 국내 건설업체의 경영상태에 심각한 영향을 미치게 되고, 이를 긴급히 타개하기 위하여 해외건설시장 진출 규모를 확대한 것으로 판단된다. 본 연구에서 분석을 통해 확인한 바와 같이 주택경기 침체에 따른 건설업체 경영상태 악화를 개선하기 위하여 해외건설시장 진출의 외연적확대는 오히려 건설업체 경영상태를 더욱더 악화시키는 결과를 초래한 것이다. 이에 따라 급박한 상황에서의 사업 전환은 오히려 수익률 확보보다 회사 내 현금흐름 확보를 위한 수단으로 전락할 수도 있기 때문에 전략적 유연성을 확보할 수 있도록 사업 다각화 수준을 지속적으로 일정 범위 안에서 관리할 필요가 있을 것으로 판단된다.

Water leakage could be caused deterioration of environmental conditions, user condition, reduction of life span and long term safety in underground concrete structure. Many materials and construction method to repair on these problems have been developed, however, it is not proper to successful repair or raise problem of increasing repair cost However, there are many limitations as practical appraisal methods due to different view of reliability for test methods. Because, it was not enough that the technical objectivity could be lack and also application of environmental condition is inadequate. In this paper, we suggest varied test methods divided to appraisal for property of matter, construction, manufacturing, specification and maintenance, friendly environmental condition. It could be more practical as a objective standard considering various angles. In summery, it should be subdivided and differentiated to accomplish proper application and to select proper materials and construction method for repair even if the synthetical condition is very complicated.

This paper presents a study on the construction condition and environmental effect of deep soil mixing. Construction condition means the difference in unconfined compressive strength with respect to the depth and location of samples. Environmental effect means alkalinity diffused from soil stabilizer. The experimental results indicate that the unconfined compressive strength vary with respect to the depth, and doesn't show consistency pattern. So, in field application we must decide a mixing ratio enough to satisfy the least unconfined compressive strength. The difference in unconfined compressive strength with respect to the location of samples is negligible. The generation of alkalinity from soil stabilizer is reduced by permeating in non-improved soil and it is expected that the diffusion of alkalinity has no environmental effect on soil and ground water.

Recently, a structure has been larger and higher under the improvement of construction technique. So, a mass concrete constructions that a mat foundation thickness of structure is over 80cm have been many. Also, because of the reason of high strength of concrete, the matter of thermal crack have become an important task to be solved absolutely. tn a cause of a thermal crack occurrence, there are material used, mixture of concrete, construction condition and so forth. In this study, we executed temperature and stress analysis of mat foundation to know the effect of the construction condition on a thermal crack of mat foundation. And we evaluated quantitatively about the occurrence possibility of thermal crack using the hydration heat analysis program. By using of this analysis technique, we will can control skilfully the quality of a mat foundation in advance.

The construction noise and vibration is a serious social problem in the downtown. This results in many expenses and delays of construction process because of the satisfactory settlement of popular complaints. In this study, we analyze the dispute mediation cases on the damages of construction noise and vibration and the noise and vibration condition in construction sites by using questionnaire surveys.

With the ever-increasing important of high-speed information in society as we move towards the 21 st century. Interior design and it's working condition has been changed a great deal included a sort of each special character and make a difference against the others. It used to be find a great poles asunder of worker's safety and project quality according to the environmental dimension of interior construction field as if they should be a pleasantness or poor condition. This research aimed to improvement of environmental construction field of interior with construction engineers and particular interior labors in 4 phases as : ⅠThe preparatory phase : -Secure a Budget, Environmental safety supervisor -Fix of Design quality, Construction period. -Choice of Construction method, Sub constructing Ⅱ. Starting work phase ; -Capacity , Safety of temporary power line. -Carriage, Stock of Material -Safety of Electronic tools, -Personal protector. Ⅲ. Working period ; -Ventilation, I illumination of working place. -Measurement of environmental working condition Ⅳ.Finish working phase ; -Analysis of measurement data. -Evaluation and making up for the weak point. -Keeping data.

The technical expert standing system of our construction industry is operated by the Ministry of Labor subjective national technical qualification law, as the professional engineer, architect and architect-engineer and so on. The construction management(CM) which is introduced on middle 1990 activates a building industry the condition of the essential indispensability for is becoming, is not officially recognized with is judged as the nostril people for qualification of the civil CM educational institutions ha the certification which is a each educational program and a separate way and it is the actual condition which is become accomplished, In this research, it observes the capital increase reserve problem point which is a domestic CM and the certification integration which is a report and system anger it leads and with national certified qualification it develops to present the improvement program for, it does to sleep.

With the social demands for tall building, the level of techniques for construction become high and there are various building materials. Also, the construction system become very complicated with the increase of worker. In spite of above facts, the method of construction management depends on the experimental capacity of a construction manager, and there are many unreasonable elements. These elements prevent well-going in construction process. To solve this problem, it is necessary to make a new system of construction management which is adequate for the condition of company and the contents of construction. In this study, the characteristic of production system and the present condition of construction management were investigated with the help of survey. Thus, the new method of construction management which can clear the previous problems was proposed.
