A Graphical Representation Framework for Enhanced Visualization of Construction Control Processes

Abstract

Graphical representation for construction control information--processes such as scheduling, budgeting and RFIs--follows no formalized method. Many graphics neglect relevant information necessary to highlight trends in or relationships between processes. The principles of data graphics offer visual capabilities beyond those currently employed by the construction industry to display appropriate information in a manner that enhances comprehension of control processes. This paper describes a method that incorporates four tasks; those of structuring and filtering data, editing for density and communicating efficiently; as necessary to creating effective data graphics. In addition to an evaluation technique, these tasks are outlined in a coherent framework. Several construction control processes are then described with respect to these four tasks. Focused application of the framework to the budgeting process produces four graphics that are subsequently evaluated by industry professionals. Conclusions detailed at the end of this document draw together lessons learned from the process of creating data graphics as well as from quantitative and qualitative evaluations of the visual cost report.
