Analysis of Extension of Time and Suspension of Work Provisions in Standard Specifications for Highways

Abstract

Construction projects are often faced with unforeseen events that require adjustments to project schedules or temporary suspension of work. To deal with these contingencies, the U.S. Departments of Transportation (DOTs) provide guidelines and regulations in their Standard Specifications (SSs) documents. However, several states exhibit a deficiency in providing crucial information and clarity regarding the approval reasons for extensions of time (EOT) or suspensions of work (SOW). This thesis conducts a comprehensive comparative analysis of the extension and suspension of work clauses in all U.S. DOT standard specifications. The research methodology includes a comprehensive literature review and a detailed examination of state-specific sections of the standard specifications. By identifying commonalities and variations, this study aims to uncover key differences in the reasons and criteria for granting extensions of time, suspension of work, and provide a guideline of each section to standardize it in future practices. Standardizing approval reasons across states could ensure consistency and also transparency in decision-making processes.
