This paper presents a study on risk analysis in terms of contractor's costs in construction phase in which Crystal ball (software of Decisioneering, UK) has been utilized as a main tool. To realize it, a questionnaire survey has been carried out to identify the dominant factors that strongly influence contractor costs in Vietnam. Based on results of questionnaire investigation, the survey identified three factors which were duration of each construction task, costs of reinforcing steel, and cement. Then a spreadsheet model was created in order to analyze risks. The study also indicates that the cost of reinforcing steel and cement are the cause of risks for contractors. According to the suggested model, contractors may foresee the probability of completion within the approved budget, and the possibility of earning in accordance with owner's payment conditions.

The propose of this research is derive project management factors and evaluate its decision weight in LNG plant EPC phases. In order to research, we studied the demestic and international research trend and analysed expert opinions. Initially we derived nine project management factors in each phase of EPC. Elicited factors in research are project management, design management, cost management, time management, contract and craim management, safety management, environment management, and risk management. Then, we evaluated the weight of project management factors with expert survey method and elicitated. Finally, The remarkable points in the result are that key management factors of EPC project are project management and risk management.

Greenhouse gas emissions and excessive energy consumption have been an on-going world issue nowadays. We can find that the majority portion is caused by high-rise office buildings. In order to resolve these problems, it is extremely important to implement various active or passive strategies in a building design. To successfully meet these design goals and energy reduction approaches, a project building must utilize an efficient design process from the early start. One of the most effective project delivery process called Integrated Project Delivery (IPD) will be implemented in a case study project building (KEPCO) during design phase and show how important it is to plan a project's green environmental performance goal together through an early collaboration from all key project participants, which helps to construct an successful green building design without any critical construction pitfalls.

Cost management always being the matters for project manager as well as other entities involved the construction projects. Vietnam is emerging country, many construction works were carried out and lot of construction projects will be developed in the near future with a huge investment capital come from outside and inside Vietnam. In recent years, international project management firms enter the Vietnam construction market, some issues emerged need to be solved. In which cost and schedule of the construction project was put in a thoroughly consider of not only project management team but also stakeholders. The research attempts to identify and assess the relationship of factors affecting the construction cost in construction phase in Ho Chi Minh City, Vietnam. Five main factor groups Owners/clients; Consultants; Contractors; Resource and Other were identified to propose the solution for cost management.

As the number of high-rise building construction projects grows up, the subject of the transportation planning has become one of the grave issue. however important decision making are made by the experience of the a planner without the rational plans for information sharing. therefore, the purpose of this study is to suggest a plan of prefect information management not only for describing drafting process for transportation planning but also for systematizing information used in the procurement, transportation and construction phase to achieve these objectives, this study 1)analyzes the prior theory about transportation planning, 2)performs a case study of actual project to embody the problems of site management by analyzing the results of interviewing experts. In conclusion, the following factors are systematized : 1)the structure of drafting process for transportation planning, 2)the contents of information used in the procurement, transportation and construction phase, 3)the actual condition of code breakdown structure in transportation Planning phase. It is anticipated that the proposed methodology would be able to improve information management among the related engineers and accumulated data that might be used in similar construction projects in Korea.

소프트웨어 개발 프로젝트는 성공률이 30% 밖에 되지 않는 어려운 과제이다. 소프트웨어 개발 프로젝트가 실패하는 이유는 여러 가지가 있을 수 있으나, 체계적인 관리 소홀이 큰 비중을 차지하고 있다. 특히, 완성도가 떨어지는 산출물을 다음 단계로 진행시키는 것은 많은 시간과 노력을 허비하여 프로젝트를 실패로 이끌 수 있다. 이를 방지하기 위해 채택되고 있는 방식은 동료 검토(Peer Review) 또는 인스펙션(Inspection) 등과 같은 산출물들에 대한 검토활동이다. 문제가 발견된 산출물들은 다시 개발자에게 돌아가서 수정하게 되는데, 이 과정을 재작업 (Rework)이라고 한다. 프로젝트 관리자가 완성도가 떨어지는 산출물들을 다음 단계로 넘겨서 오류에 대한 막대한 비용을 지출하고 기간을 지연시키는 등의 사고를 막기 위하여, 본 연구에서는 재작업의 충실도를 높일 수 있는 방법을 연구하였다. 즉 프로젝트의 재작업 시에 작업분석을 시행함으로써 재작업된 결과의 검토 수준을 달리하는 재작업지표를 개발하였고, 이에 대한 검증을 위해 4개의 프로젝트를 선택하여 개발된 지표의 적용 여부를 관찰하고 그 효율성을 입증하였다.

Utilizing a building model design of the investigation factors and structured questionnaire, the results of an investigation concerning the improvement factors in the construction phase, as perceived by academic staffs including graduate students, designers, contractors and property management teams, are presented. Findings reveal that management commitment dominate improvement factors for building projects, although construction firms frequently mentioned the team work in design firms. Significant improvements in building projects are obtained when college programs include courses that treat the administrative aspects involved in the building project and that continuing education programs cover quality training. Eighteen predominant selection factors are identified, ranked and correlated.

This paper presents the continuous commissioning process, information on the case study facility, improved system operation, and building energy consumption measures before and after continuous commissioning implementation. Continuous commissioning is an ongoing process to resolve operating problems, improve comfort, optimize energy use and identify retrofits for existing commercial and institutional buildings and central plant facilities. Continuous commissioning process consists of two phases. The first phase is the project development phase and the second phase implements and verifies project performance. Results of a case study show that continuous commissioning implementation can reduce energy costs. The energy reports show the electricity savings of 22% and gas savings of 47% on an average.

The domestic construction industry recognize that review of design and construct-ability has the devastating effects. The way to take advantage of BIM for increase the possibility of discovered the design errors in advance are being discussed a lot recently. Since 2012, Public procurement published that the Turn-key project which is the more than 50 billion won in construction have to let the BIM-based design be mandatory. However, people expected the advent of BIM technology can resolve the existing design errors. But the situation is the connection of design stage and construction stage is very insufficient in domestic. Therefore, in this study understanding the types of design errors in construction phase. according the review of design errors before construction. Then can acceleration the application of BIM to improve the workability in a construction site.

In the trend of building enlargement, high-rise and irregular shaped building, domestic application of BIM in construction phase is increasing in recent years. BIM that is based on a three-dimensional, requires a specific building expression. Model expression level required for each phase such as design, construction, and maintenance of the construction project can be different. BIM model to apply in practice is difficult because it is not clear to set up the criteria for the expression level of construction BIM model. And it has a limit that is lower productivity in construction project. Therefore, this study considers the way of the improvement and analyzes the application for representation level of construction BIM model through the survey. By analyzing of the survey results, this study will be to present a basis for an appropriate expression level setting of construction BIM model.
