of many stakeholders with the aim of achieving a built facility, possibly at the best price, highest quality and within the best specified time frame. The procurement process of every construction or infrastructure project is identified to be a very vital process of project's realization. Simply put, a transparent and successful procurement process is a key determinant of completing a project promptly and within the estimated budget. According to Clough et al. (2000) and Martins (2009), procurement includes purchasing, sourcing and every other activity connected to providing supplies, materials, equipment, workforce, knowledge, management services, and supervision to accomplish stipulated objectives of an infrastructure project. Procurement usually connects a highly fragmented supply side, typically professionals in the construction industry which include contractors, architects, engineers, suppliers, surveyors, labourers, and builders to a less fragmented demand side which includes clients, project representatives, owners and financiers. Bower (2003) highlighted that since every construction project goes through a procurement phase, there is a high potential for procurement as a practice to influence project management in the positive direction. Likewise, a possible flaw in procurement can create an adverse effect on project management. The susceptibility of any procurement phase to corruption exposes an entire project to the risk and awful impacts of corruption. There is, therefore the need to critically and empirically access the vulnerabilities and other associated risks the procurement process faces regarding corruption. Over the past two decades, there has been a growing interest in IP, contributing immensely to the increase in the body of knowledge in the subject area. However, there is an absence of unified view and a systematic review of research studies dedicated to IP over the years which is essential for further studies. This study, therefore, aims to conduct a systematic and a holistic review of corrupt practices in IP processes. While carrying out the stipulated aim, the following specific objectives will be addressed in this study: 1. Identify the degree of thematic or topical coverage of the subject matter in construction and engineering management research; and 2. Determine and propose future research directions on corruption research in IP. This study explores these two objectives in the subsequent sections. This
