Building Information modeling is playing an important role in transforming the construction industry. It helped the industry with better visualization, minimum design errors, and excellent planning of the construction activities. Time and cost saving can be effectively achieved by using BIM for any construction project. It improves information exchange between all the project stakeholders. However, the development of earthwork 3D BIM is still underway and has not been fully implemented yet. This paper presents the study of a complete process for Earthwork BIM design using Autodesk Civil 3D. A real site road construction project is used as a case study to explain the process of earthwork modeling, starting from laser scanning to 3D model. Quantity take off calculation is very important part of any road construction project so during this study earthwork volume from two 3D earthwork model is calculated. The results obtained through this study will be the basis for future work which has been concluded in this paper.

An effective logistics management is necessary for successful construction projects. So, prompt and precise logistics information collecting and management is needed, but there has been no systematic and effective method for this, Therefore, in this research, a standardized plan for RFID application in logistics management that could comprehend processes in building construction projects, was developed. With the 7 generalized process types that comprehend processes in construction projects, critical factors that should be considered for RFID applications were derived, and systematic and efficient application method for building projects were developed.

Overseas construction projects tend to be more complex than domestic projects, being exposed to more external risks, such as politics, economy, society, and culture, as well as more internal risks from the project itself. It is crucial to have an early understanding of the project condition, in order to be well prepared in various phases of the project. This study compares a structural equation model and multiple regression analysis, in their capacity to predict cost performance of international construction projects. The structural equation model shows a more accurate prediction of cost performance than does regression analysis, due to its intrinsic capability of considering various cost factors in a systematic way.

Excavation for construction is implemented in natural geographical terrain using a variety of construction equipment. Therefore, 3D excavation simulation requires integration of geographical and equipment modeling. This paper proposes a technique that integrates geographical and equipment modeling for 3D simulations of construction excavation. The geographical model uses a digital map to show ground surface changes during excavation and the equipment model shows equipment movement and placement. This combination produced a state of the art 3D simulation environment that can be used for machine guidance. An equipment operator can use the 3D excavation simulation to help construction equipment operators with decisions during excavation work and consequently improve productivity.

In the tall building construction, the slab formwork largely impacts on construction cost. Because productivity of a slab formwork is influenced by a number of and the efficiency of equipment, using the equipment-based construction method, an appropriate equipment input planning is crucial for the productivity. Meanwhile, the general equipment input planning is conducted by intuition based on experience due to the lack of equipment productivity data. Thus, this study develop a simulation model to analyze table formwork productivity and to propose an optimum equipment input plan that reflects the construction process, based on the full consideration of the economic factors. This study developed a simulation model by using CYCLONE and the data for the model was collected by measuring the duration of each unit activity in the tall building where table forms were applied. It is expected that a simulation model helps users to make better decision on the equipment input planning of slab formwork.

건축공사시 민원의 발생은 경우에 따라 비용보상, 공사중지, 행정처벌 등으로 인해 건설현장의 공사수행에 많은 어려움을 초래하고 있다. 따라서 본 연구는 건축민원의 사례 중 신축공사에 관한 민원사례를 연도별, 권역별, 발생시점별로 민원발생원인과 처리실태를 분석함으로써 건축민원의 특성을 파악하였다. 본 연구의 결과를 보면 (1) 연도별 건축민원을 분석한 결과 민원인들의 생활수준 및 의식수준이 향상됨에 따라 건축 민원 발생건수가 증가추세에 있다. (2) 권역별 건축민원을 분석한 결과 강남권역이 다른 지역에 비해 민원발생비율이 높게 나타났다. (3) 발생시선별 민원은 주로 공사중에 96%가 발생하는 것으로 나타났다. 이에 본 연구는 분석 내용을 토대로 시공자가 해당 권역에서 공사 시 주로 어떤 민원이 발생하는지를 사전에 예측하고 처리함으로써, 결과적으로 공사피해를 최소화 할 수 있는 자료로 활용될 것으로 사료된다.

Construction projects are high-risk activities. When undertaking such projects in an international setting, it can be complicated by foreign exchange (FOREX) fluctuation risk. This affects the construction business performance in various ways, namely its progress due to delays, which in turn create further problems, specifically cost overruns as a result of price increase in raw materials, disputes, arbitration, litigation and even, total abandonment. Thus, the effective management of FOREX fluctuations is crucial. Previous studies have focused on the need for contract safeguards, adequate insurance, careful planning and management, as well as foreign exchange futures hedging to address some of the risks triggered by FOREX fluctuations. An analysis of FOREX fluctuations in the international construction industry revealed that more often it was focused on project-specific issues. Currently, there is a relative lack of awareness on Organizational Capabilities (OC), the abilities that owned by the organization, which is essential in managing the impact of FOREX fluctuations. Where research has focused on OC, these are viewed in isolation. Therefore, this study attempts to close the gap by proposing a framework on managing the impact of FOREX fluctuations in the international construction industry, employing the OC perspective.

Issues in the construction industry of Cambodia in ASEAN Economic Community (AEC) is the main priority to be identified before identifying causing factors in order to find out recommendations, to improve this sector, and to survive in this community. Two major issues were identified from the literature review and the investigation, namely i) Long-term vision and its policy, and ii) practice culture. The total sample collected from concerned government officers and engineers in Cambodia were 463. Factor analysis was then conducted to find out the issues, and as the results, there are five issues in two main groups: (i) the Organization's vision and its skill, which consist of a vision of the organization, knowledge and skill, and less investmen in the construction sector; (ii) Knowledge and motivation towards the AEC, which consist of knowledge about the AEC, and level to promote organization for the AEC.

This paper probes into safety leadership in construction and its impacts on site safety performance. A safety leadership model for construction is proposed. It contains two impacting paths of safety leadership, namely safety management and safety culture. By action research, safety improvement is achieved through leadership fulfillment on construction sites.
