Assessment of delay and cost-overrun in federal road construction project in Abuja

Abstract

Poor road infrastructure in Nigeria is a significant challenge, just like poverty, insecurity, and unemployment. The construction of road in the country is characterized by numerous challenges throughout the project life cycle. Some of these challenges are project delay and cost overrun, corruption and fraud, faulty contractual process among others. Objectives of this study are to identify factors influencing delays and cost overruns in road construction project, to rank these factors base on their impacts and importance, and to suggest conservative ways to address the future challenges that can result from delays and cost overruns of future road construction projects. The research instruments include in-depth literature review, fieldwork, questionnaire administration, and interview. Inferential statistics such as Relative importance index (RII) and Mean Value techniques were used to analyze collected data. The result of the study identified factors influencing delays and cost overruns in road construction projects as; man related, money-related, machine-related, material related, environmental-related, and method related factors. Analysis using RII and MV ranked man and money related as the highest factors for delay and cost overrun respectively. Hence, the research recommends that the Government should create an enabling environment, making suitable policy for the construction company to operate.

Delay Risk Assessment in Crusher System Construction at Pt Freeport Indonesia Underground Mine

“…The construction delay risks related to material is in line with previous studies (Zhang et al 2020;Egila et al 2020;Durdyev and Hosseini, 2019;Abdullah and Alshibani, 2018;Rao et al 2016;Iqbal et al 2015). The PTFI's crusher system main materials are specific, big size and heavy.…”

“…The construction delay risks related to resources is in line with previous studies (Egila et al 2020;Zhang et al 2020;Durdyev and Hosseini, 2019;Derakhsanfar et al 2019;Zidane and Andersen, 2018;Iqbal et al 2015). Construction of the crusher system was carried out using PTFI's own resources.…”

“…The questionnaire consisted of a list of identified risks of delay submitted to respondents to provide a score on both likelihood and consequence variables on each risk. Likelihood is defined as how often the possibility of a risk event occurring when the project is implemented environment (Egila et al 2020); design quality (Mpofu et al 2017;Hong et al 2017;Zidane and Andersen, 2018;Jimoh et al 2016); scope and design change (Mpofu et al 2017;Hong et al 2017;Zidane and Andersen 2018;Jimoh et al 2016); materials (Iqbal et al 2015;Rao et al 2016;Zhang et al 2020;Abdullah and Alshibani, 2018;Durdyev and Hosseini, 2019;Egila et al 2020); administrative (Zidane and Andersen, 2018); resources (Egila et al 2020;Iqbal et al 2015;Derakhshanfar et al 2019;Zidane and Andersen, 2018;Zhang et al 2020;Durdyev and Hosseini, 2019); project management (Mpofu et al 2017;Hong et al 2017;Rao et al 2016;Zidane and Andersen, 2018;Abdullah and Alshibani, 2018;Durdyev and Hosseini, 2019); project team communication and coordination (Caldas and Gupta, 2016;Rao et al 2016;Linh and Hadikusumo, 2014;Zidane and Andersen, 2018;Abdullah and Alshibani, 2018;Durdyev and Hosseini, 2019); quality control (Linh and Hadikusumo, 2014;Zidane and Andersen, 2018);...…”
