Safety Assessment of Construction Site Layout Using Geographic Information System

Abstract

Construction site layouts involve identifying the positions of temporary facilities on site, and play a major role in the safety and productivity of operations, particularly when site space is restricted. This paper presents a new method of safety assessment of construction site using geographic information system (GIS). First, safety issues on construction sites are discussed and the factors that contribute to unsafe sites are outlined. A procedure for dynamic safety assessment of site layout has been developed in a GIS to obtain proper safety zones around the construction temporary facilities. Safety-related temporary facilities and potential places for locating temporary facilities were established. Furthermore, optimum placement of temporary facilities on the site was considered. An application example is analyzed to demonstrate the application of the model in assessment of construction site layouts based on safety consideration. This shows the capability of GIS combination for proper site layout which can lead to significant improvement in the safety and cost performance construction
