Feasibility Study of 4D CAD in Commercial Construction

Abstract

What are the major findmgs of the investigation? 4 0 model development stage: It is crucial to have a complete schedule and to establish the level of detail to be used prior to 3D CAD model development for the 4D model to be used according to its origmal purpose. Carrent Izinitation~ of4D CAD: Current 4D models and 4D tools are not flexible and their applicability limited. Fatare reqzlired iqbrouements: Future improvements include facilitating 4D model generation, its manipulation and relaying detected problems to users through knowledge based systems. What outputs were generated (software, other reports, video, other)? 4D model of FDC office building, this report. 6. Research Status: What is the status of the research? Completed. What is the logcal next step? Conduct further research pertaining to the h t a t i o n s described in the report. Are the results ready to be applied or do they need further development? Both. What adktional efforts are required before this research could be applied? A more detailed 4D model, improvements of current 4D tools.

How to measure the benefits of BIM — A case study approach

“…Furthermore, Homayouni et al 2010;Krigsvoll, 2008;Kang et al, 2007;Koo and Fischer, 2000, provide many insights into the other dimensions of BIM and their possible implications on the investments and returns of BIM projects.…”

Temporal Visualization of Building Occupancy Phase

“…Our points of departure for spatio-temporal visualization are based on two perspectives: construction and Geographic Information Systems (GIS) visualization. For construction visualization, a common approach is known as 4D CAD, where user can playback construction duration and visualize construction status on 3D models based on construction schedule (Koo and Fischer 2000). In 4D CAD, main visualization techniques are color-coding and visibility.…”

Web-Based Integrated Project Controls System

“…This necessitates the need of project manager's ability to plan, implement, and sustain an efficient and comprehensive methodology for progress monitoring to promptly recognize, process and communicate variations between actual and planned performances as early as possible [5] [6]. The main challenge for project managers and project controls managers alike is the essential desire to combine and integrate the information gathered and maintained by these various entities within the organization [10] [11] [16]. Project controls usually pursue to integrate variant tools and applications together so that they can get reliable information across those tools and applications.…”
