The nature of civil infrastructure projects can be described as complex and large-scale systems that are dynamically associated with diverse organizations and participants. Large budgets, collaboration efforts, and IT strategies are involved in major projects to increase the efficiency and effectiveness of all site activities involved. Emerging IT-based computational environments are providing a feasible vision of ubiquitous computing for the improvement of productivity and efficiency. This paper introduces the serviceability criteria of wireless sensor network to investigate the practical and technical considerations. Among the criteria, reliability issue was chosen for experimental analysis to analyze the equivalent distance between receiver and transmitter. The performance measurement indicates that the degraded ratio compared with the line-of-sight condition increases in accordance with the thickness and dielectric constant of construction material.
