ANALYSIS OF INFORMATION STRUCTURE IN INFRASTRUCTURE LIFECYCLE

This paper discusses the structure of infrastructure information in order to explain its meaning and role in infrastructure lifecycles. The schema of infrastructure information can be represented in the form of a pyramid diagram in an abstract-concrete scale, and an information lifecycle can be divided into five periods: fetal period, young age, youth, mature age and old age. In the infrastructure information pyramid, civil engineering ideas are placed at the top and are related to specific infrastructures below via policies and other parameters. The big pyramid constitutes a holistic body together with people, region, climate and natural environment. In the spatiotemporal structure of the pyramid model, information technology is represented as acquisition, representation/processing, prediction, projection, life management, operation, communication, and information management. These contribute to the solution of information delay and the improvement of the efficiency of construction processes and the quality of products.
