Development of a Risk Analysis Model for Schedule Delays in Infrastructure Construction Projects in Puerto Rico

Abstract

This paper presents a risk analysis model for schedule delays in infrastructure construction projects in Puerto Rico. The model was developed through five phases aligned with the PMBOK risk management framework: risk identification, risk classification, risk analysis, risk prioritization, and risk response planning. Fourteen delay risk factors were identified through literature review, project data, and expert consultation with construction professionals with 11 to more than 34 years of experience. The risks were classified into six categories and scored using occurrence frequency and delay duration. Permit and government approval delays and imported material delivery delays were the highest priority risks. Advance material procurement and early permit submission were rated as the most effective mitigation strategies.
