Impacts of Natural Disasters on the Construction Industry: Contractors’ Perspectives

Contractors are at the core of the construction industry and the forefront of disaster response and reconstruction programs. The resilience capacity and the wellbeing of the contracting industry are crucial. This study investigates the impacts of natural hazard disasters on construction contractors. Semi-structured interviews with twelve senior executives from leading construction firms were conducted, and the data was thematically analysed. The research revealed four prominent themes: opportunities arising from disaster events, workforce and materials challenges, incurred damages and losses, and weather-related disruptions. The increased project demands resulting from damages by disasters constitute growth opportunities for the contractors, and the urgent nature of the response and reconstruction works usually entail lower levels of pre-construction bureaucracies. However, the sudden hike in demand introduces significant challenges for the sector. Workforce shortages due to labour migration to affected areas, material shortages, and financial losses from uncompensated overheads and damages were experienced. One study finding was that contractors employ various strategies to manage these impacts, including workforce redistribution, multi-skilling training initiatives, and technological solutions such as GPS tracking systems for resource management. Additional impacts revealed included weather-related disruptions in project delivery and performance due to climate change and the changing weather pattern in New Zealand. While the construction sector demonstrates adaptability in disaster response, there is a critical need for more robust disaster preparedness strategies, including formal resource-sharing agreements, regional resource pools, and climate-adjusted planning and scheduling models.
