Article Abstract

The author demonstrates an effective methodology for improving design and construction project performance.

Engineering and Construction (E&C) already has a systematic process in place, due in part to specifications from the Construction Specification Institute (CSI) and the American Institute of Architects (AIA). The process follows the natural flow of work: project is conceived, feasibility/other studied, design criteria established, design is output, engineering reviewed, long and short lead items procured, site is prepared, etc. Each step can be seen as a probability density function (pdf), cumulating in a project pdf.

Quality measurement in a construction project occurs almost entirely during the design phase -- quality problems in later phases are almost always due to quality problems in the earlier phases. Solutions to these problems are based primarily on a wealth of experience. To measure the quality of these solutions requires comparing each project to a common base. Quality Cost Analysis can improve a single quality attribute in an independent case. However, since construction projects cannot wait until the next project before improving quality, the author illustrates Design of Experiments (DOE) as another useful tool.

The author also provides a listing of several construction professional societies and the quality standards they devised.
