Abstract
The objective of the paper is to develop a validated scale to measure the factors that cause delays in infrastructure projects. The study employed a standard three phase scale development procedure of Churchill (1979) which was augmented subsequently by Nunnally, Bernstein and Berge (1994) and Prakash and Phadtare (2018). In phase one, 73 factors that cause delays were identified, which were reduced to 45 based on literature review and expert opinions. These 45 factors were subjected to an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) in phase two and three, respectively, to refine and establish convergent, discriminant and nomological validity of the scale. The study confirms that delays in infrastructure projects happen due to six factors, i.e., Contractor Related Factors (CON); Consultant Related Factors (CS); External Factors (EX); Labour Related Factors (LR); Material Related Factors (MT) and Design Related Factors (DJ). The study is particularly useful for the firms engaged in the development of infrastructure projects globally, as it identifies and ranks the factors that cause delays in a project. However, the study being confirmatory in nature only confirms the grouping of factors causing delays and is also limited by the possibility of sampling error.

Construction is an essential component of economic growth and development
The study contributes to the body of knowledge by proposing a refined and validated scale which can be a useful measure in all infrastructure projects
Summary
The increased spending in the construction sector acts as a stimulant to economic growth. Earlier studies have established a positive relationship between the share of construction in gross domestic product and the level of per capita income (Turin, 1973; Wells, 1986). Construction economists such as Jackman (2010), Myers (2008), Tan (2002), Hillebrandt (2000), Bon (1992), Wells (1986) and Turin (1978) emphasized the significance of the construction sector in economic growth
