Investigating the Relationship between Delay an‎d Project Control Methods in Construction Projects

Delays in construction projects, as one of the main challenges in the construction industry, impose significant financial an‎d time costs on stakeholders. This issue highlights the need to investigate the relationship between delay, project control methods, an‎d project performance, because identifying delay factors an‎d improving control methods can lead to enhancing project productivity. This study aimed to investigate this relationship in Iranian construction projects. The research method was descriptive-analytical with a mixed approach (quantitative an‎d qualitative). In the qualitative part, data were collected through semi-structured interviews with 11 experts between 2010 an‎d 2014 an‎d analysed using the grounded theory method. In the quantitative part, a questionnaire was distributed among 107 managers, engineers, an‎d contractors of construction projects, an‎d the data were analysed using structural equation modelling (PLS-SEM). The statistical population consisted of individuals with at least 5 years of experience in construction projects with delays exceeding 10%. Qualitative results showed that delays were mainly caused by financial (lack of liquidity, late payment by the client), managerial (contractors’ incoordination, poor planning), an‎d operational (lack of materials an‎d skilled labour) factors. Modern project control methods such as EVM, Primavera, an‎d agile methods are effective in reducing delays, but they depend on the client’s support an‎d technological infrastructure. Quantitative analysis confirmed that the causes of delays have a strong impact on project control methods (path coefficient 0.591) an‎d a weaker impact on project performance (path coefficient 0.205), an‎d project control methods improve performance (path coefficient 0.241). These findings emphasise the need to strengthen coordination, training, an‎d the use of modern tools to reduce delays an‎d improve project performance.
