This paper presents the core technology of Construction Business Process Automation to model and automate construction business processes. Business Process Reengineering (BPR) and Automation (BPA) have been recognized as one of the important aspects in construction business management. However, BPR requires a lot of efforts to identify, document, implement, execute, maintain, and keep track thousands of business processes to deliver a project. Moreover, existing BPA technologies used in existing Enterprise Resource Planning (ERP) systems do not lend themselves to effective scalability for construction business process management. Application of Workflow and Object Technologies would be quite effective in implementing a scalable enterprise application for construction community. This paper present the technologies and methodologies for automating construction business processes by addressing how: 1) Automated construction management tasks are developed as software components, 2) The process modeling is facilitated by dragging-and dropping task components in a network, 3) Raising business requests and instantiating corresponding process instances are delivered, and 4) Business process instances are executed by using workflow technology based on real-time simulation engine. This paper presents how the construction business process automation is achieved by using equipment reservation and cancellation processes simplified intentionally.

The architecture, engineering and construction (AEC) industry is beginning to utilize Building Information Modeling (BIM), benefiting from the resulting improved visualization and productivity, better coordination of construction drawings, building documents that contain embedded links to virtual information, faster delivery, and lower costs. However, construction firms often face challenges when reorganizing their company structure to take full advantage of these benefits. This paper proposes an organizational structure that will enable engineering-construction firms to successfully adopt and implement BIM for major construction projects. A case study research method is utilized based on in-depth interviews with four BIM directors and vice presidents charged with BIM adoption, implementation and education. Organizational transformation challenges and recommendations are discussed in detail for those considering implementing BIM in the engineering-construction industry. Topics such as organizational changes in the firm, costs and benefits of BIM implementation, strategies of BIM implementation (execution) plan, BIM education, risks and opportunities associated with BIM, BIM software, contract methods, human resource management and new hires, and the future implementation and direction of BIM are discussed in detail.

Cash management is a major concern for all contractors in the construction industry. It is arguable that cash is the most critical resource of all. A contractor needs to secure sufficient funds to navigate the project to the end, while keeping an eye on maximizing profits along the way. Past research attempted to address such topic via developing models to tackle the time-cost tradeoff problem, cash flow forecasting, and cash flow management. Yet, little was done to integrate the three aspects of cash management together. This paper, as such, presents a comprehensive model that integrates the time-cost tradeoff problem, cash flow management, and cash flow forecasting. First, the model determines the project optimal completion time by considering the different alternative construction methods available for executing project activities. Second, it investigates different funding alternatives and proposes a project-level cash management plan. Two funding alternatives are considered; they are borrowing and company own financing. The model was built as a combinatorial optimization model that utilizes ant colony search capabilities. The model also utilizes Microsoft Project software and spreadsheets to maintain an environment that incorporates activities, their durations, and other project data, in order to estimate project completion time and cost. Ant Colony Optimization algorithm was coded as a Macro program using VBA. Finally, an example project was used to test the developed model, where it acted reliably in maximizing the contractor's profit in the test project.

Recently, the scale of construction project is getting bigger compared to previous projects. Therefore, the job stress of the field manager responsible for the construction project is getting more and more intense. Therefore, construction companies should establish a job stress management plan for stable human resource management of the field managers. From this perspective, in this study was developed a job stress measurement system in connection with MBTI personality types. The developed system allows the job stress of the field manager to be judged on a scale from 1 to 9 points. Accordingly, it is expected that construction companies will contribute to the effective management of field managers in the future.

건설 프로젝트의 자원관리는 공사원가의 절감, 건축물의 공정 및 품질확보에 직접적으로 관계되어 이외의 공사관리요소와 함께 매우 중요한 요소를 차지하고 있다. 하지만 자원소요계획은 공사초기에 수립되고 고려요소가 다양하여 전사적 차원의 자원소요계획을 수립하기에는 한계가 있고, 관리자간의 정보단절로 실적정보관리가 불가능하다. 건설공사의 유기적 관리를 위해서는 각 관리요소의 체계적 구성이 필요하며, 각 관리간의 사업수행정보와 실적자료의 주기적인 갱신으로 이루어져야 한다. 이에 현장변동상창을 반영하고 효과적인 자원소요계획을 수립하기 위해서는 비용 일정 통합관리의 실적 데이터를 이용하여 자원소요량 산출근거를 명확히 하고, 효율적인 자원소요계획체계를 구성하여야 한다. 본 논문에서는 비용$\cdot$일정 통합관리를 이용한 자원소요량 산출방법을 제시하였으며, 비용$\cdot$일정 통합관리를 이용한 자원 조달관리 업무프로세스를 분석하여 체계적인 자원소요계획 체계를 마련하였다.

과거 건설공사의 목표는 원가절감과 공기단축을 통한 효율성 증진이었다. 이에 비하여 안전관리는 오랜 기간 동안 소홀히 되어온 것이 사실이다. 하지만 최근 건설 산업 내에서 안전관리로 패러다임 전환이 일어나고 있으며, 이에 따라 안전관리의 중요성이 부각되고 있다. 또한 건설공사가 보다 대형화, 복잡화됨에 따라 사고의 규모가 더욱 더 커지고 있어, 건설현장에서는 보다 확실한 안전관리가 요구되고 있다. 이러한 배경 하에 본 연구는 작업자 중심의 현장 안전관리 시스템을 제안하고자 한다. 시스템 요소기술로는 위치 추적 기술(RTLS-Real Time Locating System), BIM(Building Information Modeling)기반의 모니터링 시스템(BIM Based Monitoring System), 데이터 마트(Data Mart), 알람 기술(Alarm System)이 복합적으로 적용된다. 본 시스템을 통하여 현장에서는 가변적인 상황 및 작업자에 대한 관리가 가능하게 됨으로써 기존의 정적인 관리 형태에서 벗어나 보다 폭 넓은 안전관리가 가능해 질 것이다. 또한 작업자 중심의 안전관리를 통하여 보다 체계적이고, 발전된 형태의 실시간 안전관리를 하고자 한다.
