Assessment of Delay Factors and its Impacts on Selected Road Construction Supervised by Department of Road

Abstract

The objective of the study was to analyze the factors causing delay, their impacts, and the perception of local stakeholder towards the delay caused by delay causing factors. Questionnaire surveys were conducted and examination of records from concerned stakeholders within the research area has been carried out. The factors affecting the project delay were ranked using ‘five-point’ scale ranged from 1 (strongly disagree) to 5 (strongly agree) and transformed to Relative Importance Index (RII). This study was carried out on the basis of literature review and the questionnaire survey on selected road to know the opinion of different parties involved. The questionnaire contained questions on delay causing factors identified through literature review and it came to eight groups and its impacts to five groups and perceptions of local stakeholder towards the delay caused by these delay factors into three groups on three roads i.e. Bharatpur-Meghauli road, Bharatpur-Bypass road, Baseni-Padampur road in Bharatpur Metropolitan City. The top five delay factors identified through the analysis of RII were political interference by political parties, timely payment to labors, local and political pressure, financial problem of the contractor and poor communication of consultant with other working parties. External factor was found to be the ranked one delay causing factors followed by labor factor, project factor, contractor factor and consultant factor. Time overrun cost overrun, wastages and under-utilization of human resources, cost inflation for equipment and materials due to extension of time and reputation of all parties’ involved in the projects were the impacts of delays. The SPI for all three roads was found less than 1 indicating all three projects were behind the schedule (time overrun). For the perception of local stakeholder towards the delay on road construction: accident on site, price inflation in goods and services, increase in noise pollution, increased in air pollution due to dust and particulates and human health were the top most main perceptions.
