| The occupational indoor air quality (IAQ) during construction plays a major role in workers. health and safety as construction activities frequently generate airborne pollutants. Exposure to dusts, fumes, fibres and volatile organic compounds (VOCs) can cause health issues such as lung cancer, asthma and silicosis. The occupational exposure limits for hazardous airborne pollutants in the workplace is legislated by the Alberta Occupational Health and Safety Code. This thesis proposes a methodology to predict the occupational indoor air quality during construction activities utilizing Building Information Modeling (BIM). The single zone mass balance model was used to determine the indoor pollutant concentration; the model was integrated with BIM to calculate the air pollutant concentration during construction activities. This method allows the stakeholders to determine the indoor air quality before actual construction work. A case study demonstrates the proposed methodology during a drywall sanding activity to verify its effectiveness. |
