Experimental Research in Construction

Abstract

Humans’ unique use of tools originated with their capability to observe, to link causes with effects and to conduct trial and error experiments. Experimental research today is still using these same basic elements albeit augmented by sophisticated tools and methods. Researchers conducting scientific experiments in the construction arena, however, face a “harsh” environment to work in. This paper draws from 20 years of experimental work in construction and engineering education. It provides a short historic background before discussing a framework useful to categorize the various ways researchers conducted experiments that provided meaningful results. Many examples are used to underscore the most important points.
