Abstract
Delays in road construction projects due to various reasons are a major problem facing construction professionals. The incapability of finishing projects punctually and within a given budget is a persistent issue worldwide. This study aims to determine the ten principal causes of delay in road construction projects in 25 developing countries across the globe. The study involves two steps. First, the authors compiled information regarding the most frequent delays in a road construction project. Second, they analyzed the intensity of each cause of delay in these projects. Being more accurate in the methodology, given the nature of the information, the researchers used a quasi-meta-analysis for processing the data. Half (50%) of the countries have similar causes of delay, and likewise, 50% of the countries identified the top ten primary causes of delay in road construction projects based on the intensity results. This study uses the results of the intensity. According to the results of the homologation, the lack of experience of the construction manager, inadequate planning/scheduling, and influence on people’s land alongside the road construction project (expropriation for the construction of the project) have more significant impacts than frequent changes in the design (which was listed as the most frequent cause of delay).
Highlights
The primary function of roads is to provide accessibility and mobility
Road projects are being listed as the primary focus in their national budget, given that a good road network contributes to the development of the economy and national growth
The causes of delays are quite comparable across developing countries, several factors unambiguously pertain to local industries, socio-economic backgrounds, cultural matters, and project features, such as land disputes and problems of the right of way for roads
Summary
The primary function of roads is to provide accessibility and mobility. Presently, developing countries around the world are prioritizing the improvement and linking of their road networks. The fourth category of delay or the Concurrent Delay is when the concurrency dispute is not from the position of defining the project’s severe delays but from the viewpoint of conveying accountability for damages related to critical path delays In their investigation for the main causes of construction delays, Trauner, Manginelli, and Nagata [10] presented a relationship between the delays. Faridi and El-Sayegh [11] said that construction delays are the most recurring problems in the building industry, which hurt the success of the projects in terms of safety, cost, time, and quality It must be a priority for the owner and the contractor to define and identify the most significant causes for project delay to reduce the scope of its impact on the construction project
