Impact of scope definition indeterminacy on iron triangle performances in public building construction projects

Abstract

Public building projects are vital in the construction industry since they can provide a variety of public benefits and improve the efficiency of public utilities. The Iron Triangle is a crucial driver of public building projects, ensuring project success through proper management of the Iron Triangle's components. However, when it comes to the elements that have identified in this research, the scope is the most important factor to consider. As a result, analysing the impact of the Iron Triangle due to scope indeterminacy in public building projects is a critical performance metric for reducing negative impacts on the Iron Triangle and ensuring the efficacy of public building projects. Therefore, the study focuses on the assessing the above impact of scope indeterminacy on the performance Iron Triangle in public building projects. Case content analysis and descriptive statistics were used to analyse the empirical data acquired from expert interviews and a questionnaire survey. The studies revealed twenty-seven causes for scope indeterminacy in public building projects, with twelve (12) of them being unique to public building projects. In addition to that, the study discovered 34 handling strategies for reducing the impact of scope indeterminacy. In the context of public building projects, eleven of the most severe causes of scope indeterminacy for Iron Triangle performance were discovered, with "Lack of Planning" and "Lack of Concentrate on Defining Scope" being the most severe causes of scope indeterminacy for Iron Triangle performance in public building projects.
