Research paper thumbnail of Managing a Large Volume of Data for Public Engineering Enterprise

It requires a good understanding of the underlying data and their structures as well as a good software tool that enables extracting, transforming, and cleansing of data stored in different platforms. Moreover, domain expertise and knowledge are needed in order to reason about these data to enable early detection of business risks and chances. These challenges are unique and differ from system to system and from organization to organization. This paper focuses on these challenges and presents a case study conducted in developing an information management system for a government agency in Thailand to integrate data from various sources and provide business insights for its management team. This paper discusses some technical difficulties experienced in its current information management practice and describes our resolutions to overcome them by using the developed system. Finally...

Determining paths for transporting materials at a construction site is an important planning acti... more Determining paths for transporting materials at a construction site is an important planning activity. Typically, construction of building facilities entails various activities involving transporting, storing, preparing, and placing building materials at different locations within the boundary of a site. It is necessary that materials be transported to storage locations and become readily available and accessible when they are needed. Discrete-event simulation tools exist for modeling and visualizing movement of pieces of equipment and materials and identifying related spatial conflicts. The simulation tools allow engineers to conduct what-if analysis and to assess the effectiveness of material-handling operations. However, such simulation tools do not necessarily provide a solution that result in conflict-free operation. This paper presents a research approach that focuses on determining conflict-free paths for material transportation. The approach takes building design and schedul...

Research paper thumbnail of Assessment of the Capabilities of a Commercial 4D CAD System to Visualize Equipment Space Requirements on Construction Sites

Construction Research Congress, 2003

These spatial conflicts can cause delays at the start and at the completion of activities resulting in possible late completion of a project and in claims between involved parties. Currently, some commercially available 4D CAD systems enable spatial representations of the dynamic motions of equipment operations. This paper discusses the technical capabilities of a commercially available 4D CAD system to model, visualize, communicate, and coordinate spaces required by equipment. It summarizes the benefits and limitations of equipment space representations on a largescale construction project using a 4D CAD simulation system and states some recommendations for improvement.

Research paper thumbnail of Automated generation of workspace requirements of mobile crane operations to support conflict detection

Automation in Construction, 2007

To identify spatial conflicts related to crane operations, project engineers need to model and reason about spatio-temporal behaviors of cranes and coordinate them within a dynamic construction environment across time. Current approaches for identifying equipmentrelated spatial conflicts are based on discrete-event simulation of dynamic equipment motion. The accuracy of spatial conflicts detected using such approaches can be error-prone since it depends on a rate of time increment for the simulation to be set by the user. This paper presents an approach for generating workspaces that encapsulate spaces occupied by mobile cranes moving during an operation. It also discusses an assessment of the effectiveness of the approach in identifying spatial conflicts between mobile cranes and building components.

Research paper thumbnail of Transformation of a 4D product and process model to generate motion of mobile cranes

Automation in Construction, 2009

Current tools for visualizing equipment motion in three dimensions (3D) and across time have limitations due to their reliance on users in modeling a sequence of movement of each piece of equipment experientially and manually. This paper presents an approach for automatically generating motions of mobile cranes to support conflict detection. This approach builds on and extends existing approaches in product and process modeling and visualization of construction operations. It takes a product and process model that contains building design and schedule information of a specific project together with specifications of cranes and construction methods utilized by the project as input. The crane specifications and construction methods constitute project-independent information that describes how cranes should be operated during the execution of activities. The output of the approach is a transformed product and process model that incorporates a set of operations and motions of cranes, which can be used for identifying spatial conflicts associated with crane operations. Validation studies show that the developed approach can be used to model different types of mobile cranes and generate their motion during operations, which enables detection of spatial conflicts related to cranes.
