Linked Data for Cross-Domain Constraint Information Sharing in LNG Construction

Abstract: Reliable construction plans are vital for effective collaboration across a projectŐs design, procurement and construction. Numerous constraints arising from engineering, supply chains and construction site are the main factors affecting planning reliability. Currently, there is not an efficient way to access all these constraint information because they are stored in various systems and managed by multiple domain participants. This paper aims to utilise Linked Data Technology to enable links to be set between data (i.e. constraint information) in different systems and therefore connect these systems into a single global data space. A prototype of the proposed approach was developed and tested on a sample LNG project.

A framework for evaluating it benefits in construction companies

Abstract: Information Technology (IT) is seen as an enabling mechanism to allow radical change to be effected in construction industry. However, firms in the construction industry are slowly responding and adapting to developments in information and communication technologies (Love, et al., 2000). A key barrier to the more effective exploitation and application of IT in the construction sector has been the lack of investment on a scale comparable with other sectors. A primary reason cited for the low level of investment is the low level of perceived benefits from IT investments amongst construction business managers (Andresen, et al., 2000). Based on literature review and a survey in the local construction companies, this paper presents a “5Cs” evaluation framework to assist construction companies to predict, measure and evaluate the potential benefits that can or should be achieved by the introduction of IT. The proposed framework answers questions concerning about all factors that need to be considered in the evaluation, such as why, what, when, who and how to perform the evaluation. It is not only presented as a research result but also can be used as a guideline in practice.

Assessement of 4D modeling for schedule visualization in construction engineering education

Abstract: This paper describes a longitudinal study to assess the value of using 4D modeling in construction engi-neering education for schedule visualization. In 2005, a preliminary 4D learning module was developed and incorpo-rated in a project management course to help students learn how to develop a Short Interval Production Schedule. Comparative assessment methods were used to examine the learning product (solution quality). Direct observation and surveys were used to examine presentation effectiveness and student perceptions. This assessment concluded that 4D modeling is an effective learning aid for students to better achieve learning outcomes. In 2006, a more rigorous as-sessment methodology was designed to determine the impact of the 4D learning module on both the learning process and final exercise product. In addition to examining a traditional 4D modeling process, we also developed a 4D model generation interface titled the Virtual Construction Simulator (VCS), which allows students to generate a construction schedule directly from a 3D model. Ten student groups using these two interfaces were observed, videotaped, analyzed and compared. The final results from a detailed content analysis of the videotapes shows that both processes were valuable for improving the students’ learning experience. The VCS interface showed additional value beyond the cur-rent 4D CAD application.
