The COVID-19 pandemic was one of the unforeseeable risks in the construction industry. The supply chain (SC) trend globally and locally was disrupted by the sudden pandemic that forced people to limit the movement to minimize the further infection of the virus. Joint risk management (JRM) is a strategy that encourages and enhances collaboration in construction. Furthermore, with the complexity of the industry, joint risk management is an alternative tool for managing unforeseeable risks in construction. The objective of this research is to identify the impact, problems, and solutions companies have encountered in the construction industry supply chain amid the pandemic in CALABARZON. Moreover, developed a strategy using joint risk management. The data for the case study was collected through interviews. The study results show that some companies are not significantly affected by the pandemic in terms of projects. However, construction companies face delays and lack in supply, problems in mobility, an increase in raw and construction material, and problems with human resources. The construction adapted to the situation and strategized through effective planning, scheduling, time management, and good communication with each project stakeholder. Lastly, a joint risk management strategy was developed to encourage collaboration with each construction project stakeholder.
