The Request for Proposal (RFP) is a fundamental document frequently employed by construction owners for procuring services, with a focus on criteria beyond cost alone. Particularly prevalent in alternative project delivery methods like design-build, construction manager at risk, and integrated project delivery, the RFP solicitation plays a pivotal role. This study delves into the landscape of RFP standardization efforts within the construction industry, conducting a comprehensive review, analysis, and evaluation of 215 sample RFPs drawn from across all states in the United States. The culmination of this research effort is the development of a standardized RFP template, equipped with a comprehensive framework adaptable to various construction project delivery methods. This study marks the inaugural exploration of this subject, making a substantive contribution to the existing body of literature on this vital topic.
