Though significant works of literature are available for project scheduling, project delay in the road construction industry is a common phenomenon. The main objective of this paper is to identify the real-time critical characteristics that influence the project delay in the New Zealand road construction industry and how to manage these delays during project scheduling. The real-time critical characteristics considered are based on environment, resource & surroundings (ERS) to develop a dynamic project schedule. This study adopted semi-structured interviews/ expert opinion and systematic literature review data to determine the critical characteristics of a roading project such as daily weather, Instrument and equipment breakdown, geological and landscaping, material shortage, design errors, pandemic and events. The data were analysed by using descriptive analysis, Likert scale, and thematic analysis techniques to understand the relationship of these factors. Based on the analysis a dynamic model for managing these factors proposed, which in turn can reduce the uncertainty and scheduling errors during the planning phase. This would aid in lesser scheduling modification during the execution phase. In practice, this study will be helpful for road contractors to overcome road construction delays, reduce cost, aid in stakeholder management and sustainable development.
