Daily site interpretation tools for different hierchical levels in a construction project Yue, Benjamin Tsan-Pin


This thesis is an extension of Fayek’s work (Fayek 1992) on the automated interpretation of a construction activity’s problems and suggestion of possible corrective actions. It consists of three major parts. First, an extensive field test was undertaken in order to obtain a real data set to test and validate both Fayek’s work and extensions to it. As part of this exercise, an attempt was made to capture the expertise of seasoned construction personnel regarding the selection of corrective actions as a function of problem source and prevailing job site conditions. The original problem source list was extended from seven problem sources to fifteen, and corrective actions for the new sources were identified. The second part of the thesis, which constitutes the core of the work, deals with the formulation of a general, higher-level analysis schema. It includes integrating across all problem sources and corrective actions at the activity level, and the detection of patterns of problems at the trade and overall project levels, along with the suggestion of higher-level corrective actions. One of the challenges confronted in this work is the need to deal with conflicting corrective actions arising from the diagnosis. Several examples are given to illustrate the workings of a prototype. Lastly, the graphical representation of daily site data is partially explored. Construction personnel are often overwhelmed by the amount of data that describes a project. The use of graphics, especially the stacking of different graphs, helps the user to identify patterns of problems and provides insights into causation. Various graphical images are presented, along with suggestions for more complex three dimensional representations.
