Abstract: The overall aim of this dissertation is to determine the slip resistivity of Housing Development Board (HDB) estate walkways in preventing slip and fall accidents in both dry and wet weather. To achieve this, three separate studies were undertaken. The first study was to determine the slip resistance of walkway surfaces objectively (in terms of hard data) by measuring the dynamic coefficient of friction (DCOF) and wet dynamic friction in both dry and wet conditions through the employment of the Tortus 3 device and the wet pendulum tester respectively. The readings were compared to Singapore standard (SS) 485:2011, “Specification for slip resistance classification of pedestrian surface material” to evaluate if it met the specifications, and safe for pedestrians use. Before commencing the measurement, 7 common types of walkway surfaces were identified. The results showed that measurements for dry condition using Tortus 3 tribometer met the classification defined by (SS) 485. However, when it comes to wet condition measurements, the results varied, showing concrete imprint, smooth finish tiles and metal drain with a classification of Z, while concrete surfaces with smooth finish, diamond plate drain covers and textured tiles with a classification of Y, both did not meet the required classification. The purpose of the second study was to evaluate the performance of the walkway surfaces subjectively by interviewing residents of Toa Payoh town who frequented the walkways. They were asked to rate the performance in terms of slip resistivity of the walkway surfaces in both dry and wet conditions and their responses were correlated with the results of the first study. The third study involves a case study in which an elderly in Sembawang reportedly slipped and fell during a rainy day on his way home. This observations study serve to identify factors that could cause the slips and falls, and more importantly provide a real life example and reference to identify similar conditions/problems in this dissertation’s study of walkways to predict the likelihood of slipping and falling. Results suggest that similar conditions that could cause slipping and falling were found in Toa Payoh HDB estate walkways Ultimately, two findings can be concluded from this research. The first is data collected suggests that walkways constructed of tiles with smooth finish are the most accident prone among the 7 surfaces in wet conditions. Secondly, findings highlight the existence of iii unexpected slippery spots in the certain walkway designs found in Toa Payoh town which heightens the probability of slipping and falling. Collectively, the results concluded from this dissertation support its hypothesis that certain walkway surfaces in HDB estates pose a safety concern in the area of slip initiation and fall especially in rainy weather
