Abstract
Abstract. Among the various civil engineering tasks, geospatial monitoring of engineering structures takes an essential place. In the digital era, the concept of geospatial monitoring needs a total re-definition. The widespread dissemination of BIM creates new opportunities and challenges simultaneously for the monitoring problem. The presented paper aims to develop the new concept of geospatial monitoring tailored to BIM features and possibilities. The interrelationship of BIM, building life cycle, and geospatial monitoring of engineering structures has been demonstrated. The critical element of geospatial monitoring is its workflow. Up today, BIM is considered separately from monitoring workflow. However, the main stages of geospatial monitoring cannot get by without BIM. That is why the new monitoring workflow with BIM support has been suggested. The workflow takes into account three main stages: design, data collection, and analysis. For each of these stages, the role and application of BIM have been examined. The question of geospatial monitoring design has been addressed, and the new approach to monitoring design with BIM involvement has been suggested. It was pointed out the meaning of BIM for the data collection stage and especially for analysis. The refined concept of geospatial monitoring has been considered as a case study of high-rise building monitoring.

Summary
Modern geospatial monitoring comprises many tools and different equipment. Despite the well-developed concept, it has become obsolete due to the involvement of new technologies and especially software. The issue of the integration and complex processing of geodetic and non-geodetic information provided by, e.g., extensometers, piezometers, etc., creates new challenges. The person conducting geospatial monitoring encounters the big problem: various equipment, different measured values with different meanings, and different software for their processing. Surveyors mostly use BIM as a source of geometric parameters that engineering structures must comply with (Li et al 2007, Tang et al 2010, Qin et al, 2021) Such a situation is typical for supporting the construction process, but how about geospatial monitoring? Section four addresses the contemporary concept of geospatial monitoring for high-rise building monitoring, and section five outlines conclusions
