Science is a huge pyramid, still rising upon the previous studies. Therefore, the stronger the previous studies the higher the pyramid. Yet in order to make the studies more efficient some professional methods are needed. Throughout the years many different research methodologies emerges. New technology provided researchers to use more reliable and feasible methods. Some of those research technics are more popular than the rest. Sometimes a study may be performed only by using a specific research technic but mostly a few of those technics are used at the same time. Hence, it might be possible to compare the outcomes of different methods on same study. The presented study analysis and evaluates the development and performance measures trends of research methods used in the field of civil engineering. The database used in this paper has been taken from three different sources “science direct”, “ProQuest”, “Scopus”, it presents a detailed description about the research methods evolution and their impact in different fields in construction and management. The technique used in this study has been derived from meta-analysis research method because of its simplicity in extracting the needed information and summarize them in proper way. The “findings and discussion” part presents the evolution of “35” different research methods in four different decades, namely, “from 1990 to 2000”, “from 2001 to 2010”, “from 2010 to 2020”, and the overall evolution “from 1990 to 2020” by using more than “700” different research reports, the impact of each research methods is represented by drawing a graph for each decade and analyze it for different branches in civil engineering. Lastly, a proper conclusion has been discussed with a future expectation about the use of the research methods.
