Best-value procurement enables highway agencies to make informed selections by assessing not only cost but also technical criteria. However, assessing technical criteria is necessary but not sufficient to reach a best-value selection that is not biased toward cost. In the last two decades, the ranges of scores used in the assessment of technical proposals have shown to play an influential role in the bias toward cost of best-value selections.

Research Objective

This study investigates whether there is any significant difference between technical scores assigned to design-builders in best-value procurements using different award algorithms.

Research Methods

The research used statistical and goodness-of-fit analysis to characterize, evaluate, and compare 822 technical scores from 240 design-build highway projects procured using best-value procurement in the U.S.
