Integrated visualized time control system for repetitive construction projects

Construction control is an essential management function for successful delivery and achieving of construction projects’ goals. Considerable research efforts have been done regarding project control. However, literature suffers from a lack of visualizing the controlling process. With the growth of using visualization techniques in construction, Building Information Modeling (BIM) and Geographic Information System (GIS) have recently attained a widespread contribution in visualization of construction progress. BIM is a process of creating virtual models data that represents building facilities. In this research, BIM represents a platform for nD (n-Dimensional) visualization of construction progress. The advantages of this paper stems from three main contributions for construction projects control: 1) developing of a mathematical model for time control of repetitive construction projects; 2) an automated system to dynamically integrate project progress with BIM technique; and 3) a GIS-based tool to visualize the progress of distributed sites. The developed model provides abundant information to help decision makers take the appropriate corrective actions. An example application is presented to demonstrate the applicability of the developed system.

Building Information Modeling (BIM) application framework: The process of expanding from 3D to computable nD

The utilization of Building Information Modeling (BIM) has been growing significantly and translating into the support of various tasks within the construction industry. In relation to such a growth, many approaches that leverage dimensions of information stored in BIM model are being developed. Through this, it is possible to allow all stakeholders to retrieve and generate information from the same model, enabling them to work cohesively. To identify gaps of existing work and evaluate new studies in this area, a BIM application framework is developed and discussed in this paper. Such a framework gives an overview of BIM applications in the construction industry. A literature review, within this framework, has been conducted and the result reveals a research gap for BIM applications in the project domains of quality, safety and environmental management. A computable multi-dimensional (nD) model is difficult to establish in these areas because with continuously changing conditions, the decision making rules for evaluating whether an individual component is considered good quality, or whether a construction site is safe, also vary as the construction progresses. A process of expanding from 3D to computable nD models, specifically, a possible way to integrate safety, quality and carbon emission variables into BIM during the construction phase of a project is explained in this paper. As examples, the processes of utilizing nD models on real construction sites are described. It is believed to benefit the industry by providing a computable BIM and enabling all project participants to extract any information required for decision making. Finally, the framework is used to identify areas to extend BIM research.     

The advantages of information management through building information modelling

As building information modelling (BIM) is positioned by governments and construction professionals as a solution to the problems in the construction industry, research is needed into the benefits BIM actually confers. The focus here is on the effectiveness of BIM as a medium for communicating information within a construction team. A case study of an offsite precast concrete fabrication facility was conducted. At the time of the study, the facility was supplying precast units for four public sector projects, and using four information management systems: e-mail, a construction project extranet tool, an Enterprise Resource Planning system and a new BIM-based system. The flow of information through the four media was measured and visualized as the projects progressed. This quantitative measurement of information flow was combined with qualitative data from interviews with facility staff. It was found that the introduction of the BIM-based system diverted information flow through the building model and away from the extranet system. The use of e-mail was largely unaffected. BIM allowed considerably more accurate, on-time and appropriate exchange of information. It is concluded it is possible to quantify some of the benefits of BIM to information management. This research paves the way for future research into the management of more construction project information linked more closely to building models.

Integrating building information models with construction process simulations for project scheduling support

Many construction practitioners and researchers have developed four-dimensional (4D) models by linking the three-dimensional (3D) components of a building information model (BIM) with the network activities of a project schedule. In such a 4D model, the BIM provides limited information, except for the 3D components. To enhance the benefits of using BIM in 4D applications, this study proposes an interface system that uses the BIMs ability with regard to quantity takeoffs of required materials (such as steel, forms, and concrete) to support site-level operations simulation, ultimately leading to the generation of a project schedule. Our proposed system includes mechanisms that collect, store, and transfer information among various software packages. Facilitated by the BIM's quantity takeoffs, the operations simulation is able to consider uncertain durations of work tasks, which allows it to consider the competing needs for resources among multiple work tasks, and to evaluate various resource allocation strategies in order to create a suitable construction plan. Finally, the resulting project schedule is also linked to the BIM 3D components, thus producing an improved BIM-based 4D model.     

BIM嵌入项目管理过程的关键问题探索

Building Information Modeling (BIM) outsourcing among general contractors

Building Information Modeling (BIM) is a process used by Architecture Engineering Construction (AEC) stakeholders which simulates a construction project in a multi-dimensional digital model and provides multitudes of project benefits from project inception to its occupancy. However, a variety of barriers impede a holistic BIM implementation. Due to these barriers, some general contractors outsource the creation and use of BIM models to specialized Information Technology (IT) firms. Since limited literature currently exists for BIM outsourcing, this study aims to identify BIM outsourcing patterns among the general contractors across the US and the perceived impacts it has on construction projects. Analysis of two-hundred and fifty-two complete responses from general contracting firms determines that 45% of responding companies have outsourced BIM, this signifies that outsourcing has become an important facet of BIM implementation. Data was also collected on company demographics, BIM outsourcing locations, strategic reasons for outsourcing, and various other aspects related to BIM outsourcing. The results indicate that respondents perceive BIM outsourcing as less efficient than in-house BIM implementation. However, continued use of outsourcing for BIM functions also displays the adaptability of the industry in meeting challenges and embracing new technology through alternative methods, despite the potential risks.

Requirements for BIM platforms in the concrete reinforcement supply chain

Despite increasing adoption of Building Information Modeling for reinforced concrete, there is a lack of research to identify system requirements for BIM platforms to efficiently perform various activities throughout reinforcement supply chain. In this study, we evaluate current tools' capabilities and performance from this perspective. We first develop the information flow process model for concrete reinforcement over its supply chain. This process model provides the basis to identify the necessary capabilities for BIM tools to efficiently support and improve the entire reinforcement supply chain. The identified capabilities were compared to the implemented capabilities of the major BIM tools supporting the reinforced concrete domain. BIM tools are evaluated in four areas: design and modeling; editing, updating and optimization, interoperability, and project and construction management. This assessment illustrates development trends in the BIM software industry with regard to concrete reinforcement. Recommendations are proposed for future enhancements of BIM platforms to address current shortcomings.     

虚拟施工的BIM应用:三大高校合作项目

越来越多的设施业主要求项目组移交竣工BIM模型,以便用于建筑的运营和维护。根据项目要求的不同,业主可能将竣工模型建立与移交的责任指派给总承包商。因此,施工队伍的各成员不但越来越需要熟悉BIM建模软件的应用,还需熟悉利用可靠的设施信息支持完整BIM的必要业务流程。竣TBIM模型的创建,要求承包商首先要基于建筑师、工程师和顾问等设计师所提供的图纸和信息的基础上,创建建筑,结构和设备模型。这要求承包商的组织机构内要有一名人员具备各与专业设计模型相关的技能和知识。一旦设计模型被创建(或重新创建),承包商可将这些模型用于开发施工用的BIM模型。一个完整的施工模型通常包括:成本估算,施工进度计划、冲突检测与分析以及现场物流。业主对设施管理用竣工模型提出新增要求,包括添加运营和维护用的具体数据。本文所述项目旨在为了更好地了解,在为业主实施BIM的项目上,承包商对项目所起作用的复杂性。为实现此目标,三所大学合作建立了数个校际团队,从每所学校各抽调一名学生分配至三个团队的一个,充当BIM商业建筑项目BIM应用里的承包商角色。本文从两个方面汇报项目的挑战和细节:导师——项目组织、学习目标和策略,学生——项目组织、团队合作过程以及策略。
