【 摘 要 】

The article defines ground laser scanning (GLS) as a process of total geodetic survey with the survey system, which measures the distance between the instrument and the object's surface and records corresponding directions in horizontal and vertical planes. The components of GLS system and data obtained during the scanning are indicated. The necessity of processing the data obtained by GLS is pointed out. The main usage of laser scanning which is the obtaining of precise geometric characteristics of an object complemented with any attributive data is stated. Thus, GLS can be widely used in buildings and construction information modeling. Analyzed the range of Russian documents regulating common requirements and developing rules and the usage of information models of massive building objects for applied tasks during different object life-cycle phases as well as usage of contemporary project and survey technology, particularly GLS. The conclusion is made stating on the idea of information modeling supposes its usage containing information characterizes the building object model during the different phases of its life-cycle. In relation to stated facts the role and position of GLS in information model development of a construction site, executive and operational models of an object are pointed out.
