Abstract

To help prevent noise-induced hearing loss (NIHL), a permissible exposure limit for construction noise has been set to 90 dB over an eight-hour period by the Occupational Safety and Health Administration (OSHA). The National Institute for Occupational Safety and Health (NIOSH) has further set the recommended exposure level to be 85 dB for an eight-hour period. However, construction workers still lack enough awareness of the potential noise hazard in their workplace and the damage that long-term exposure to noise can cause. The feasibility of noise mapping has been approved in improving intuitive noise related awareness especially in urban traffic planning, however, little research of its benefits has been explored in construction worker safety training. Building information modeling (BIM) is increasingly applied in construction safety related analysis and training, while integration of noise hazard into BIM has not been employed. Therefore, this paper presents an innovative framework of integrating wearable sensing data into BIM for construction workplace noise hazard prediction in safety training. The objective of the framework is to predict and visualize noise spatial distribution in BIM based on collected scattered data from wearable noise sensors. A case study is conducted in an indoor renovation project to validate the feasibility of the proposed framework and evaluate its performance.
