Abstract: Technological advancement has allowed the design of more complex structures consequently making the traditional method of construction inefficient. Additionally, the decline of productivity has called for the use of modern technology such as augmented reality to improved construction productivity. This study investigated the productivity of using Interactive Augmented Reality (IAR) method for the construction of complex brick wall designs. A total of 17 people with no previous bricklaying experience participated in experiments to construct three different types of brick walls with different complexities. The walls were constructed using the traditional method (no technology) and with IAR and productivities recorded. The Wilcoxon/Kruskal-Wallis non-parametric test indicated statistically significant difference in the mean productivity of the IAR (ranging from 2 to 2.5 minutes/brick) and the traditional method (ranging from 6.61 to 49.4 minutes/brick). The results indicate that the average productivity rate for placing bricks per minute using the IAR method was significantly higher than that of the traditional method.
