Potential applications of geographic information systems to construction industry

Geographic Information Systems (GIS) are one of the fastest growing computer-based technologies of the 1990s, yet, their full potential in the construction industry has not been realized. This technology provides adequate capabilities for solving problems that involve the integration and analysis of large volumes of spatial and descriptive data from a variety of sources. This technology supports the interaction of multiple participants such that they can approach problems in a more comprehensive and systematic way. The primary objectives of this paper are to describe GIS technology and explore potential construction applications that can benefit from the implementation of this technology. An example application of this technology to contractor prequalification is provided. One benefit expected from the application of GIS to contractor prequalification is the creation of a comprehensive data base. This data base can provide a wide range of construction users with a mechanism for rapid retrieval and manipulation capability to satisfy their need of spatial and descriptive information required in the process. Practical considerations regarding GIS application to the construction industry are also addressed. Finally, several research areas worthy of further investigation are noted.
