Sand and dust storms (SDSs) are recognized as meteorological hazards that negatively impact air quality, visibility, human health, and various socioeconomic factors. Dust reduces visibility, which may contribute to a variety of transportation and navigation safety hazards, such as flight delays. The State of Kuwait experiences SDSs frequently in spring and summer due to strong northwesterly winds that are locally called shamal and strong southeasterly winds locally known as kous. The dust deposited in Kuwait is characterized by fine lightweight particles that can be easily suspended in air due to wind movement. These particles are contaminated with emissions from traffic, the cement industry, and petroleum refineries, as well as construction dust. No previous studies have tackled the impact of dust on construction schedules and worker health and performance in Kuwait. The aim of this study is to assess the impact of SDSs on the progress of construction projects as well as worker health and performance. For the study, 120 questionnaires were distributed to contractors and construction companies, and 73 responses were received. The results indicate a significant impact on project timelines from delays due to SDSs. Although most construction activities are disabled during SDSs, 22% of the sample respondents experienced respiratory problems during such dust events. The results of this study will contribute to supporting decision-makers, such as engineering firms and consultancies, in determining potential SDSs risks to project timelines, as well as to the health and safety of workers and nearby residents.
